AngularJS HTML DOM

In AngularJS, some directives can be used to bind application data to attributes of HTML DOM elements.

These directives are:

Directive	Description
ng-disabled	It disables a given control.
ng-show	It shows a given control.
ng-hide	It hides a given control.
ng-click	It represents an AangularJS click event.

ng-disabled directive:The ng-disabled directive binds AngularJS application data to the disabled attribute of HTML elements. In the below code, it binds a model to a checkbox.

    <input type = "checkbox" ng-model = "enableDisableButton">Disable Button
<button ng-disabled = "enableDisableButton">Click Me!</button>
 

ng-show directive: The ng-show directive shows or hides an HTML element. In the below code, it binds a model to a checkbox.

    <input type = "checkbox" ng-model = "showHide1">Show Button
<button ng-show = "showHide1">Click Me!</button> 

ng-hide directive: The ng-hide directive hides or shows an HTML element. In the below code, it binds a model to a checkbox.

<input type = "checkbox" ng-model = "showHide2">Hide Button
<button ng-hide = "showHide2">Click Me!</button> 

ng-click directive: The ng-click directive counts the total clicks an HTML element. In the below code, it binds a model to a checkbox.

 <p>Total click: {{ clickCounter }}</p>
<button ng-click = "clickCounter = clickCounter + 1">Click Me!</button> 

Let's take an example to deploy the all above directives and test the variations:

See this example:

<!DOCTYPE html>
<html>
<head>
      <title>AngularJS HTML DOM</title>
</head>
<body>
      <h2>AngularJS Sample Application</h2>
      <div ng-app = "">
           <table border = "0">
            <tr>
               <td><input type = "checkbox" ng-model = "enableDisableButton">Disable Button</td>
               <td><button ng-disabled = "enableDisableButton">Click Me!</button></td>
            </tr>
            <tr>
               <td><input type = "checkbox" ng-model = "showHide1">Show Button</td>
               <td><button ng-show = "showHide1">Click Me!</button></td>
            </tr>
             <tr>
               <td><input type = "checkbox" ng-model = "showHide2">Hide Button</td>
               <td><button ng-hide = "showHide2">Click Me!</button></td>
            </tr>
             <tr>
               <td><p>Total click: {{ clickCounter }}</p></td>
               <td><button ng-click = "clickCounter = clickCounter + 1">Click Me!</button></td>
            </tr>
         </table>
         </div>
<script src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
</body>
