Show instantly as write into the TextBox using Angular JS

This is my first post about Angular JS. Here in this post I will show you how to show the text into <p> tag as you type into a TextBox. I will do it with the help of Angular JS. Before starting it is important to discuss some thing about Angular JS.

So, what is Angular JS actually?

  1. AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. Angular's data binding and dependency injection eliminate much of the code you currently have to write.
To add this into your project add the following line into the head section.



aNow its time to start the project. Once again I clarify the aim of the project. There will be one TextBox and one <p> tag. As you type in the TextBox the text will be show in the <p> tag. You can do this in the TextChange event in the JavaScript or JQuery. But with the help of Angular JS its a matter of one line.

Lets come how to do this.

Type Text:

ng-app : directive defines an AngularJS application.
ng-model : directive binds the value of HTML controls like input, select, textarea etc. to application data.
ng-bind : directive binds application data to the HTML view. Now run your HTML page and check it out.

Your first Angular JS page is ready to rock n roll.
