Assigning event handlers in JavaScript using DOM object property
 
10:20

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]

Style binding in angular 2

Setting inline styles with style binding is very similar to setting CSS classes with class binding. Please wtach Class binding video from Angular 2 tutorial before proceeding with this video. Notice in the example below, we have set the font color of the button using the style attribute. import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: ` [button style="color:red"]My Button[/button] ` }) export class AppComponent { } The following example sets a single style (font-weight). If the property 'isBold' is true, then font-weight style is set to bold else normal. import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: ` [button style='color:red' [style.font-weight]="isBold ? 'bold' : 'normal'"]My Button [/button] ` }) export class AppComponent { isBold: boolean = true; } style property name can be written in either dash-case or camelCase. For example, font-weight style can also be written using camel case - fontWeight. Some styles like font-size have a unit extension. To set font-size in pixels use the following syntax. This example sets font-size to 30 pixels. import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: ` [button style='color:red' [style.font-size.px]="fontSize"]My Button [/button] ` }) export class AppComponent { fontSize: number = 30; } To set multiple inline styles use NgStyle directive 1. Notice the color style is added using the style attribute 2. ngStyle is binded to addStyles() method of the AppComponent class 3. addStyles() method returns an object with 2 key/value pairs. The key is a style name, and the value is a value for the respective style property or an expression that returns the style value. 4. let is a new type of variable declaration in JavaScript. 5. let is similar to var in some respects but allows us to avoid some of the common “gotchas” that we run into when using var. 6. The differences between let and var are beyond the scope of this video. For our example, var also works fine. 7. As TypeScript is a superset of JavaScript, it supports let import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: ` [button style='color:red' [ngStyle]="addStyles()"]My Button[/button] ` }) export class AppComponent { isBold: boolean = true; fontSize: number = 30; isItalic: boolean = true; addStyles() { let styles = { 'font-weight': this.isBold ? 'bold' : 'normal', 'font-style': this.isItalic ? 'italic' : 'normal', 'font-size.px': this.fontSize }; return styles; } }

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.

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

jQuery #id selector
 
10:53
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/jquery-id-selector.html In this video we will discuss 1. What are jQuery selectors 2. Different selectors in jQuery 3. #id selector in jquery What are jQuery selectors One of the most important concept in jQuery is selectors. jQuery selectors allow you to select and manipulate HTML elements. Different selectors in jQuery jQuery selectors allow you to select html elements in the DOM by 1. Element ID 2. Element Tag Name 3. Element Class Name 4. Element attribute 5. Element Attribute values and many more Id selector in jquery To find an HTML element by ID, use the jQuery #id selector Example : The following example finds button with ID button1 and attaches the click event handler. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').click(function () { alert('jQuery Tuorial'); }); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] Changes the background colour of the button to yellow $(document).ready(function () { $('#button1').css('background-color', 'yellow'); }); Important points to remember about jQuery #id selector 1. jQuery #id selector uses the JavaScript document.getElementById() function 2. jQuery #id selector is the most efficient among all jQuery selectors. If you know the id of an element that you want to find, then always use the #id selector. 3. HTML element IDs must be unique on the page. jQuery #id selector returns only the first element, if you have 2 or more elements with the same ID. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').css('background-Color', 'yellow'); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [input id="button1" type="button" value="Click Button" /] [/body] [/html] 4. JavaScript's document.getElementById() function throws an error if the element with the given id is not found, where as jQuery #id selector will not throw an error. To check if an element is returned by the #id selector use length property. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { if ($('#button1').length ] 0) { alert('Element found') } else { alert('Element not found') } }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] 5. JavaScript's document.getElementById() and jQuery(#id) selector are not the same. document.getElementById() returns a raw DOM object where as jQuery('#id') selector returns a jQuery object that wraps the DOM object and provides jQuery methods. This is the reason you are able to call jQuery methods like css(), click() on the object returned by jQuery. To get the underlying DOM object from a jQuery object write $('#id')[0] 6. document.getElementById() is faster than jQuery('#id') selector. Use document.getElementById() over jQuery('#id') selector unless you need the extra functionality provided by the jQuery object.

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]

Change gridview row color when checkbox is checked
 
08:23
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/change-gridview-row-color-when-checkbox.html In this video we will discuss how to change gridview row color when checkbox is checked. We want to achieve this using JavaScript. The background color of the rows that are select should be grey, and the rows that are not selected should be white. We will continue with the example that we worked with in Part 3 of JavaScript with ASP.NET tutorial. Modify HeaderCheckBoxClick() and ChildCheckBoxClick() JavaScript functions as shown below. [script type="text/javascript" language="javascript"] function HeaderCheckBoxClick(checkbox) { var gridView = document.getElementById("GridView1"); for (i = 1; i [ gridView.rows.length; i++) { gridView.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked = checkbox.checked; // Depending on whether the checkbox in the header is checked or // unchecked change the background color of the data rows in the GridView if (checkbox.checked) { gridView.rows[i].style.background = '#CCCCCC'; } else { gridView.rows[i].style.background = '#FFFFFF'; } } } function ChildCheckBoxClick(checkbox) { var atleastOneCheckBoxUnchecked = false; var gridView = document.getElementById("GridView1"); for (i = 1; i [ gridView.rows.length; i++) { // Depending on whether the checkbox in the data row is checked or // unchecked change the background color of the rows in the GridView if (gridView.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked == false) { gridView.rows[i].style.background = '#FFFFFF'; atleastOneCheckBoxUnchecked = true; } else { gridView.rows[i].style.background = '#CCCCCC'; } } gridView.rows[0].cells[0].getElementsByTagName("INPUT")[0].checked = !atleastOneCheckBoxUnchecked; } [/script] The following code makes the text in a GridView row bold on mouseover and normal on mouseout protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onmouseover", "this.style.fontWeight = 'bold';"); e.Row.Attributes.Add("onmouseout", "this.style.fontWeight= 'normal';"); } }

Custom Alert Box Programming JavaScript CSS HTML Tutorial
 
12:04
Lesson Code: http://www.developphp.com/video/JavaScript/Custom-Alert-Box-Programming-Tutorial JavaScript comes equipped with stock dialog boxes that work well enough for alerting, confirming, and prompting for values. But most of the top interactive websites create their own custom dialog windows. Creating these windows yourself gives you more control over the interaction with the user, and allows you to customize every single aspect of the dialog window. In this first video lesson we will cover creating a dynamic custom alert box dialog from scratch. In the two following videos we will cover confirm and prompt boxes.
