AngularJS extends HTML through instructions, and binds data to HTML through an expression.
AngularJS is a JavaScript framework
AngularJS is a JavaScript framework. It is a library written in JavaScript.
AngularJS is published as a JavaScript file and can be added to a Web page by a script tag: <script src= "Http://apps.bdimg.com/libs/ang ... gt%3b[note] We recommend placing the script at the bottom of the <body> element.
This will increase the page load speed, because HTML loading is not subject to script loading.
Each angular.js version download: https://github.com/angular/angular.js/releases
AngularJS extends the HTML
AngularJS extends HTML through ng-directives.
The NG-APP directive defines an AngularJS application.
The Ng-model directive binds the element value (such as the value of the input field) to the application.
The ng-bind directive binds the application data to an HTML view.
AngularJS instance <! DOCTYPE html>
<meta charset= "Utf-8" >
<script src= "Http://apps.bdimg.com/libs/ang ... gt%3b
<body>
<div ng-app= "" >
<p> Name: <input type= "text" ng-model= "name" ></p>
</div>
</body>
Example Explanation:
When the page is loaded, AngularJS automatically opens.
The Ng-app directive tells the angularjs,<div> element to be the "owner" of the AngularJS application.
The Ng-model directive binds the value of the input field to the application variable name.
The ng-bind directive binds the application variable name to the InnerHTML of a paragraph.
[Note] If you remove the ng-app instruction, HTML will display the expression directly, and will not evaluate the result of an expression.
