What is Angular JS?Angular JS is Java Script framework introduced by Google in 2012 (version 1.0). It is an open source. Angular JS allows a developer to write a powerful client-side coding. To work with Angular JS just download angular js file from https://angularjs.org and reference it into your HTML, ASPX page.
The first version of Angular.js is called AngularJS. The architecture of AngularJS is based on the MVC pattern.
Let's start with Directives. What are the directives?
Directives give a way to group HTML and Java Script functionality into one bundle.
Few directives that are used in Angular JS from programming context are -
Here If isDisplay value changed to false, above div section will be hidden.
Here question may rise that, why Angular JS?
Angular JS is a very powerful tool for developing an application that requires two-way data binding.
It means if you need to change the contents of HTML you need to write code like this.
$('span').html('My first Angular JS Code');
In angular JS below code will change the value of Lable as soon as you start typing in Textbox
<input type="text" ng-model="UserName" />
Hello ! <label id="l1" ng-bind="UserName"></label>
Below is the output for above code
Angular JS expression can be written in double braces.
Example 1: Write below code in your HTML page
Output - 30
<div ng-app="" ng-init="points=[2,11,7,32,4,3]">
<p>The third result is <span ng-bind="points"></span></p>
Output - 32
