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.

  1. <input type = “checkbox” ng-model = “enableDisableButton”>Disable Button
  2. button ng-disabled = “enableDisableButton”>Click Me!</button>

  3. <head>
  4.       <title>AngularJS HTML DOM</title>
  5. </head>
  6. <body>
  7.       <h2>AngularJS Sample Application</h2>
  8.       <div ng-app = “”>
  9.            <table border = “0”>
  10.             <tr>
  11.                <td><input type = “checkbox” ng-model = “enableDisableButton”>Disable Button</td>
  12.                <td><button ng-disabled = “enableDisableButton”>Click Me!</button></td>
  13.             </tr>
  14.             <tr>
