AngularJS ng-copy Directive

The AngularJS ng-copy directive specifies the custom behavior of AngularJS when an HTML element is being copied. It doesn't override the element's original on copy event; both the ng-copy expression and the original on copy event will be executed.

It is supported by all HTML elements.

Syntax:

Parameter explanation:

expression: It specifies an expression that is executed when the text of an element is being copied.

Let's take an example to demonstrate the ng-copy directive.

See this example:

<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body ng-app="">
<input ng-copy="count = count + 1" ng-init="count=0" value="Copy this text" />
<p>The text has been copied <strong> {{count}} </strong>times.</p>
<p>This example shows that every time you copy the content in the input field, it will increase the value of the variable "count".</p>
</body>
</html>

<!doctype html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>ng-copy example</title>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>  
</head>
<body ng-app="">
  <input ng-copy="copied=true" ng-init="copied=false; value='copy me'" ng-model="value">
copied: {{copied}}
<p><strong>Note:</strong> By default value of this example is false. When you copy the text within the input field, it will be true.</p>
</body>
</html>
