JavaScript for getElementById
 
02:34
Introduction JavaScript JavaScript is a scripting or programming language that allows you to implement complex things on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. • HTML is the markup language that we use to structure and give meaning to our web content, for example defining paragraphs, headings, and data tables, or embedding images and videos in the page. • CSS is a language of style rules that we use to apply styling to our HTML content, for example setting background colors and fonts, and laying out our content in multiple columns. • JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. (Okay, not everything, but it is amazing what you can achieve with a few lines of JavaScript code.) Before You Starting JavaScript You should know basic HTML and CSS

Javascript Tutorial with Examples For Beginners (pt 1)
 
04:21
This is part one of a series of javascript programming tutorials for beginners. I've created a bunch of example and sample problems for you to solve here: http://www.pyaraapp.com/js-tutorial-1.html Go to that site, open the developer console and type in the following commands and see what happens: /* Javascript Can Change HTML Content */ document.getElementById("demo").innerHTML = "Hello There"; /* JavaScript Can Change HTML Styles (CSS) */ document.getElementById("demo").style.fontSize = "30px"; /* JavaScript Can Hide HTML Elements */ document.getElementById("demo").style.display="none"; /* JavaScript Can Show HTML Elements */ document.getElementById("demo").style.display="block"; The problem with most javascript tutorials is that they don't give you enough example problems. If you are a beginner, it is really hard to learn how to code by just watching videos. You need to go out there and really solve sample problems. What is javascript: JavaScript is the programming language of HTML and the Web. Programming makes computers do what you want them to do. JavaScript is easy to learn. This tutorial series will take you from a JavaScript beginner to an expert. Why Study JavaScript? JavaScript is one of the 3 languages all web developers must learn: 1. HTML to define the content of web pages 2. CSS to specify the layout of web pages 3. JavaScript to program the behavior of web pages This tutorial is about JavaScript, and how JavaScript works with HTML and CSS. Learn by Examples: Examples are better than 1000 words. Examples are often easier to understand than text explanations. This tutorial supplements all explanations with clarifying "Try it Yourself" examples. If you try all the examples, you will learn a lot about JavaScript, in a very short time! In this video, I will use the javascript console thats built into the chrome developer tools to get you to start writing javascript code. With the chrome browser, you will be able to write out some code and see the results immediately. Then I will show you how to store a variable and what a variable really is. Then I will go over the different types of variables and then how to output the values of these variables you created.

My Personal JavaScript Notes on How to
 
05:30
MyWebSite: https://www.aimiecaprice.com How to store an HTML elements content into a variable. How to write content to a variable using JavaScript. How to run a comparison statement on an HTML elements content When I initially dove into this, creating the condition was the thing that stumped me most. I got the rest of the equation that stated if this condition exists, do xyz. But my problem came with how do you get JavaScript to check if the condition exist and how do you create condition? Actually creating the condition is what really stump me most probably because I was over thinking it. I knew I wanted JavaScript to change the CSS display property depending on what image a user clicked...so I needed to write a function, make the image clickable, and have the function fire off "OnClick" So I created the condition inside the function which meant every time that function fired off the condition would be created by the function. JavaScript would literally write code that stated var x = 1, or var x = 2, depending on which function was being called by the user clicking various different images. . Example var x = 1; if( x == 1) { document.getElementById("desTxt1").style.display = "inline-block"; document.getElementById("desTxt2").style.display = "none"; document.getElementById("desTxt3").style.display = "none"; document.getElementById("desTxt4").style.display = "none"; document.getElementById("desTxt5").style.display = "none"; document.getElementById("desTxt6").style.display = "none"; document.getElementById("desTxt7").style.display = "none"; document.getElementById("desTxt8").style.display = "none"; document.getElementById("desTxt9").style.display = "none"; document.getElementById("desTxt10").style.display = "none"; document.getElementById("desTxt11").style.display = "none"; document.getElementById("desTxt12").style.display = "none"; }

Converting strings to numbers in JavaScript
 
17:14
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/11/converting-strings-to-numbers-in.html In this video we will discuss different methods that are available in JavaScript to convert strings to numbers. This example allows the user to enter 2 numbers and add them. Along the way we will learn the use of the following functions 1. parseInt() 2. parseFloat() 3. isNan() Here is the HTML for the web form [table style="border:1px solid black; font-family:Arial"] [tr] [td]First Number[/td] [td][asp:TextBox ID="txtFirstNumber" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Second Number[/td] [td][asp:TextBox ID="txtSecondNumber" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Result[/td] [td][asp:TextBox ID="txtResult" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td] [/td] [td] [input type="button" value="Add" id="btnAdd"/] [/td] [/tr] [/table] Include the following JavaScript in the head section of the web form. [script type="text/javascript"] function addNumbers() { var firstNumber = document.getElementById("txtFirstNumber").value; var secondNumber = document.getElementById("txtSecondNumber").value; document.getElementById("txtResult").value = firstNumber + secondNumber; } [/script] Set the onclick attribute of the Add button to call the addNumbers() function. The HTML for the button should be as shown below. [input type="button" value="Add" id="btnAdd" onclick="addNumbers()" /] Run the application and enter 20 as the first number and 10 as the second number. Click Add buton. Notice that JavaScript concatenates the numbers instead of adding them. This is because the value property of the textbox is returning the number in a string format. So we need to explicitly do the conversion. This is when parseInt() function is useful. Modify the addNumbers() JavaScript function as shown below. function addNumbers() { var firstNumber = parseInt(document.getElementById("txtFirstNumber").value); var secondNumber = parseInt(document.getElementById("txtSecondNumber").value); document.getElementById("txtResult").value = firstNumber + secondNumber; } Run the application and test. Notice that we now get 30 as expected. Let's do another test. Enter 20.5 as the first number and 10.3 as the second number. Click the Add button. Notice that the decimal part is ignored. To retain the decimal places, use parseFloat() function. function addNumbers() { var firstNumber = parseFloat(document.getElementById("txtFirstNumber").value); var secondNumber = parseFloat(document.getElementById("txtSecondNumber").value); document.getElementById("txtResult").value = firstNumber + secondNumber; } If you leave first number and second number textboxes blank or if you enter text instead of a number, and when you click the Add button, NaN is displayed in result textbox. NaN in JavaScript stands for Not-a-Number. In JavaScript we have isNaN() function which determines whether a value is an illegal number. This function returns true if the value is not a number, and false if not. Modify the addNumbers() JavaScript function as shown below. function addNumbers() { var firstNumber = parseFloat(document.getElementById("txtFirstNumber").value); if (isNaN(firstNumber)) { alert("Please enter a valid number in the first number textbox"); return; } var secondNumber = parseFloat(document.getElementById("txtSecondNumber").value); if (isNaN(secondNumber)) { alert("Please enter a valid number in the second number textbox"); return; } document.getElementById("txtResult").value = firstNumber + secondNumber; } Now, when you leave first number and second number textboxes blank or if you enter text instead of a number, and when you click the Add button, you get relevant validation error messages as expected. Let's make the validation error message a little more relevant: If the first number and second number textboxes are left blank, then we want to display the following validation messages a) First Number is required b) Second Number is required If you enter text instead of number a) Please enter a valid number in the first number textbox b) Please enter a valid number in the second number textbox

Events in JavaScript
 
17:08
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/events-in-javascript.html What is an event An event is a signal from the browser that something has happened. For example, 1. When a user clicks on an HTML element, click event occurs 2. When a user moves the mouse over an HTML element, mouseover event occurs When events occur, we can execute JavaScript code or functions in response to those events. To do this we need to associate JavaScript code or functions to the events. The function that executes in response to an event is called event handler. In JavaScript, there are several ways to associate an event handler to the event 1. Using the attributes of an HTML tag 2. Using DOM object property 3. Using special methods In this video we will discuss associating event handler methods to events using the attributes of HTML tags. In the following example, the code to execute in response to onmouseover & onmouseout events is set directly in the HTML markup. The keyword "this" references the current element. In this example "this" references the button control. [input type="button" value="Click me" id="btn" onmouseover="this.style.background= 'red'; this.style.color = 'yellow'" onmouseout="this.style.background= 'black'; this.style.color = 'white'" /] The above example, can be rewritten as shown below. In this case the code to execute in response to the event is placed inside a function and then the function is associated with the event. [input type="button" value="Click me" id="btn" onmouseover="changeColorOnMouseOver()" onmouseout="changeColorOnMouseOut()" /] [script type="text/javascript"] function changeColorOnMouseOver() { var control = document.getElementById("btn"); control.style.background = 'red'; control.style.color = 'yellow'; } function changeColorOnMouseOut() { var control = document.getElementById("btn"); control.style.background = 'black'; control.style.color = 'white'; } [/script] Events are very useful in real-world applications. For example they can be used to 1. Display confirmation dialog box on submitting a form 2. Form data validation and many more How to show confirmation dialog in JavaScript [input type="submit" value="Submit" id="btn" onclick="return confirmSubmit()" /] [script type="text/javascript"] function confirmSubmit() { if (confirm("Are you sure you want to submit")) { alert("You selected OK"); return true; } else { return false; confirm("You selected cancel"); } } [/script] JavaScript form validation example : In this example, both First Name and Last Name fields are required fields. When you type the first character in any of the textbox, the background colour is automatically changed to green. If you delete all the characters you typed or if you leave the textbox without entering any characters the background colour changes to red indicating the field is required. We made this possible using onkeyup and onblur events. onkeyup occurs when the user releases a key. onblur occurs when an element loses focus. [table] [tr] [td] First Name [/td] [td] [input type="text" id="txtFirstName" onkeyup="validateRequiredField('txtFirstName')" onblur="validateRequiredField('txtFirstName')"/] [/td] [/tr] [tr] [td] Last Name [/td] [td] [input type="text" id="txtLastName" onkeyup="validateRequiredField('txtLastName')" onblur="validateRequiredField('txtLastName')"/] [/td] [/tr] [/table] [script type="text/javascript"] function validateRequiredField(controlId) { var control = document.getElementById(controlId); control.style.color = 'white'; if (control.value == "") { control.style.background = 'red'; } else { control.style.background = 'green'; } } [/script]

How to check if JavaScript is enabled

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/02/how-to-check-if-javascript-is-enabled.html In this video we will discuss how to check if JavaScript is enabled or disabled. Let us understand this with an example. We have a page that captures Name and Gender. Both fields are required. The page relies on JavaScript being enabled for performing validation. We should always have server side validation irrespective of whether we have client side validation or not. It is not a good practice to rely just on client side validation, but for the purpose of this demo, let us say we only have client side validation. If JavaScript is enabled then we want to display the Name and Gender elements and the user can continue to use the application. If JavaScript is disabled then we want to hide the Name and Gender elements and we want to display the following message. It seems that you have disabled JavaScript. Please enable JavaScript. The easiest way to detect if JavaScript is enabled is by using noscript tag. The content inside the [noscript] element will be displayed only if scripts are not supported, or are disabled in the user's browser. [noscript] [style type="text/css"] .rootDiv { display: none; } [/style] [h1]It seems that you have disabled JavaScript. Please enable JavaScript.[/h1] [/noscript] [div id="rootElement" class="rootDiv"] [table border="1"] [tr] [td] Name [/td] [td] [input id="txtName" type="text" onfocus="validateIfEmpty('txtName')" onblur="validateIfEmpty('txtName')" onkeyup="validateIfEmpty('txtName')" /] [/td] [/tr] [tr] [td] Gender [/td] [td] [input id="txtGender" type="text" onfocus="validateIfEmpty('txtGender')" onblur="validateIfEmpty('txtGender')" onkeyup="validateIfEmpty('txtGender')" /] [/td] [/tr] [/table] [/div] [script type="text/javascript"] function validateIfEmpty(control) { var controlToValidate = document.getElementById(control); if (controlToValidate.value == "") { controlToValidate.style.background = "red"; } else { controlToValidate.style.background = "white"; } } [/script]

Белые тигрята в японском зоопарке повеселили посетителей

Белые тигрята в японском зоопарке повеселили посетителей. Белые тигрята я японском зоопарке, которые появились на свет в конце января, показались публике. И сделали это эффектно, устроив своеобразное представление. Забавная спасательная операция развернулась в японском зоопарке Тобу, что в окрестностях Токио. Два белых тигрёнка решили, что их брат не сможет самостоятельно выбраться из мини-бассейна, и пришли ему на выручку, сообщает ТВ Центр. При этом утопающий отчаянно сопротивлялся, а его крики были слышны посетителям через толстое стекло вольера. К тому моменту, когда на помощь подоспели мама-тигрица и ещё один тигрёнок, полосатым спасателям уже удалось вытащить брата на сушу. Сразу четыре детёныша редчайших белых тигров появились на свет в конце января и пока не получили клички. В мае среди посетителей проведут конкурс на лучшие имена для новых питомцев зоопарка.

javascript tutorial - selector in JavaScript and changing html content in JavaScript
 
15:56
In this video, I have discussed on selectors in javascript and how can we change content via js. resource file link https://github.com/polodev/javascript_selector_yt_bangla Javascript selector JavaScript has 2 types of selector scalar selector will return single element composite selector will return array of elements. some elements are unique in html page. like head, body, title, id etc. In this case we will get single element from selector. However in case of tag and class we will get array of element since they can be occur more than one times in html page. So whenever we found array of elements we have to extract single element from array of elements to change them. 5 css selector where first 4 is supported by querySelector and querySelectorAll tag (body) id (#hello) class (.hello) attribute([id='hello']) pseudo(a:hover) some selector which will give us single element document.body document.head document.getElementById('some_id') document.querySelector('any of first 4 css selector from state above list') some selector which will give us array of elements document.getElementsByClassName('html class') document.getElementsByTagName('htmltag') document.querySelectorAll('any of first 4 css selector from state above list') modern javascript selector querySelector and querySelectorAll document.querySelector('css selector') its a scaler type selector in js dom. it will return single element which can be change directly. It will take css selector(first 4 from state above css selector list) as argument document.querySelectorAll('css selector'); its a composite type selector in js dom. It will return array of elements. So in order to change a element we have to extract single element by their index. It will take css selector(first 4 from state above css selector list) as argument

ASP NET TextBox and JavaScript

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/03/aspnet-textbox-and-javascript.html In this video we will discuss 1. JavaScript focus method 2. JavaScript select method 3. How to count the number of characters as you type in a textbox and display that count in a label control JavaScript focus method : focus() method is used to put the keyboard cursor in a particular textbox when the web page loads so that we can start typing without having to first click in the textbox with the mouse. For example, when a web page with the following HTML and JavaScript is loaded, the keyboard cursor is already in the textbox waiting for the user to type his input. There is no need for the user to first click in the textbox with his mouse. Name : [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [script type="text/javascript"] document.getElementById("TextBox1").focus(); [/script] focus() method can be used with most HTML elements. For example, when a web page with the following HTML and JavaScript is loaded, the keyboard focus is set to DropDownList1 control. You can change the Gender value in the DropDownList by pressing ALT + Down Arrow keys simultaneously. Since we are using focus() method there is no need to first click on the DropDownList with the mouse. [table style="border:1px solid black"] [tr] [td]Name[/td] [td][asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Gender[/td] [td] [asp:DropDownList ID="DropDownList1" runat="server"] [asp:ListItem Text="Male" Value="Male"][/asp:ListItem] [asp:ListItem Text="Female" Value="Female"][/asp:ListItem] [/asp:DropDownList] [/td] [/tr] [/table] [script type="text/javascript"] document.getElementById("DropDownList1").focus(); [/script] JavaScript select method : select() method is used to select the contents of a text field, so when you start typing, the new text that you have typed will automatically replace the existing selected text. You can use select() method with textbox and textarea controls. When a web page with the following HTML and JavaScript is loaded, the text in the textarea element is selected and when you start typing, the new text that you typed will replace the existing selected text. [table style="border:1px solid black"] [tr] [td]Name[/td] [td][asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Comments[/td] [td] [asp:TextBox ID="TextBox2" TextMode="MultiLine" runat="server" Text="Type your comments here"][/asp:TextBox] [/td] [/tr] [/table] [script type="text/javascript"] document.getElementById("TextBox2").select(); [/script] How to count the number of characters as you type in a textbox and display the count in a label control Name : [asp:TextBox ID="TextBox1" runat="server" onkeyup="CountCharacters();"] [/asp:TextBox] [asp:Label ID="Label1" runat="server"][/asp:Label] [script type="text/javascript"] function CountCharacters() { document.getElementById("Label1").innerHTML = document.getElementById("TextBox1").value.length + " charactes"; } [/script]

Where should the script tag be placed in html
 
09:40
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/11/where-should-script-tag-be-placed-in.html In this video we will discuss, where should the script tag be placed in the html. Should it be placed in the body or head section of the page. In general the script tag can be placed either in the head or body section. Let's look at a few examples : Example 1 : Script tag in the head section [html] [head] [script type="text/javascript"] alert("Welcome to JavaScript Tutorial"); [/script] [/head] [body] [form id="form1" runat="server"] [/form] [/body] [/html] Example 2 : Script tag in the body section [html] [head] [/head] [body] [form id="form1" runat="server"] [/form] [script type="text/javascript"] alert("Welcome to JavaScript Tutorial"); [/script] [/body] [/html] In Example 1 we placed the script tag in the head section and in Example 2, we placed it in body section. In both the cases JavaScript works as expected. Example 3 : Sets the background color of the TextBox to red. [html] [head] [/head] [body] [form id="form1" runat="server"] [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [/form] [script type="text/javascript"] document.getElementById("TextBox1").style.backgroundColor = "red"; [/script] [/body] [/html] Example 4 : This is same as Example 3, except we moved the script tag to the head section. In this case the script will not work as expected. Depending on the browser you are using you get one of the following JavaScript error. Firefox - TypeError: document.getElementById(...) is null Chrome - Uncaught TypeError: Cannot read property 'style' of null IE - Unable to get property 'style' of undefined or null reference To see these JavaScript errors press F12 which launches developer tools. F12 works for all the 3 browsers. [html] [head] [script type="text/javascript"] document.getElementById("TextBox1").style.backgroundColor = "red"; [/script] [/head] [body] [form id="form1" runat="server"] [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [/form] [/body] [/html] Why did the JavaScript did not work in this case JavaScript code is present before the textbox control. By the time the JavaScript code is executed, the textbox is still not loaded into browser DOM (Document Object Model). This is the reason JavaScript can't find the textbox and throws a NULL reference error. In Part 6, we discussed that, in general it is a good practice to store JavaScript in an external .js file. So, if the JavaScript is present in an external file and if you are referencing it on a page using [script] element, where should such [script] element be placed. To answer this question, first let's understand what happens when a browser starts loading a web page. 1. The browser starts parsing the HTML 2. When the parser encounters a [script] tag that references an external JavaScript file. The parser stops parsing the HTML and the browser makes a request to download the script file. Until the download is complete, the parser is blocked from parsing the rest of the HTML on the page. 3. When the download is complete, that's when the parser will resume to parse the rest of the HTML. This means the page loading is stopped until all the scripts are loaded which affects user experience. In general, the suggested good practice is to place the [script] tag just before the closing [body] tag, so it doesn't block the HTML parser. However, modern browsers support async and defer attributes on scripts. These attributes tell the browser it's safe to continue parsing while the scripts are being downloaded. But even with these attributes, from a performance standpoint it is still better to place [script] tag just before closing [body] tag. According to HTTP/1.1 specification browsers download no more than two components in parallel. So, if the page has several images to download and if you place [script] tags at the top of the page, the script files start to download first which blocks the images download which adds to the total page load time.

CSS Display:Block Declaration Explained In Detail
 
02:34
CSS Display:Block Declaration Explained In Detail https://youtu.be/1IgGXzGI5AU Display block css will make it so an element takes up the entire width inside the HTML element where it resides. This is common for headlines and divs. These means if the HTML element is set to be 200 pixels wide then a block element will take up all 200 pixels of that width. Similary, if the element is 1000 pixels wide a block element will take up the whole 1000 pixel width. Or if an element is set to 100% of the page, a block element within that 100% wide parent will take up 100% of the page. The other display values available to you are: Block makes the element take up a whole row in the HTML element where it resides. Here's how it looks: display:block; Inline makes the element take up only the space it needs. Here's how it looks: display:inline; Inherit applies the same display property as its parent element. Here's how it looks: display:inherit; Display none makes elements disappear. It also makes it so the hidden element does not take up any space on the page. Here's how it looks: display:none; That's all there is to it. I hope this video helps you! If you have any questions, please leave them in the comments below.

In Part 36, we discussed, associating event handler methods to events using the attributes of HTML tags. In this video we will discuss using DOM object property to assign event handlers to events. First let us understand, what is DOM DOM stands for Document Object Model. When a browser loads a web page, the browser creates a Document Object Model of that page. The HTML DOM is created as a tree of Objects. Example : [html] [head] [title]My Page Title[/title] [/head] [body] [script type="text/javascript"] [/script] [div] [h1]This is browser DOM[/h1] [/div] [/body] [/html] JavaScript can be used to access and modify these DOM objects and their properties. For example, you can add, modify and remove HTML elements and their attributes. Along the same lines, you can use DOM object properties to assign event handlers to events. We will discuss the DOM object in detail in a later video session. We will continue with the same examples that we worked with in Part 36. Notice that in this case, we are assigning event handlers using the DOM object properties (onmouseover & onmouseout) instead of using the attributes of the HTML tag. We are using this keyword to reference the current HTML element. In this example "this" references the button control. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onmouseover = changeColorOnMouseOver; document.getElementById("btn").onmouseout = changeColorOnMouseOut; function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] The following example is same as the above. In this case we are assigning an anonymous function to onmouseover & onmouseout properties. [input type="button" value="Click me" id="btn" /] [script type="text/javascript"] document.getElementById("btn").onmouseover = function () { this.style.background = 'red'; this.style.color = 'yellow'; } document.getElementById("btn").onmouseout = function () { this.style.background = 'black'; this.style.color = 'white'; } [/script] If an event handler is assigned using both, i.e an HTML attribute and DOM object property, the handler that is assigned using the DOM object property overwrites the one assigned using HTML attribute. Here is an example. [input type="button" value="Click me" id="btn" onclick="clickHandler1()"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler set using HTML attribute"); } function clickHandler2() { alert("Handler set using DOM object property"); } [/script] Using this approach you can only assign one event handler method to a given event. The handler that is assigned last wins. In the following example, Handler2() is assigned after Handler1. So Handler2() owerites Handler1(). [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler1; document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script]
