In this article I will explain with an example, how to use ng-copy directive in AngularJS.
 
 

HTML Markup

The following HTML Markup consists of:
DIV – For applying ng-app and ng-controller AngularJS directives.
Note: If you want to learn more about these directives, please refer my article Introduction to AngularJS.
 
TextBox – For capturing user input.
The HTML INPUT TextBox has been assigned with the following AngularJS directive.
ng-copy – Called when the text in the TextBox is being copied.
SPAN – For displaying message.
<div ng-app="MyApp" ng-controller="MyController">
    <input type="text" ng-copy="Copy()" value="ASPSnippets" />
    <hr />
    Copied: <span style="font-weight:bold">{{Copied}}</span>
</div>
 
 

Implementing ng-copy Directive

Inside the HTML Markup, the following AngularJS script file is inherited:
1. angular.min.js
Then, inside the Controller, the Copied variable is set to FALSE.
When the text in the TextBox is being copied, the Copy function is called and it is also called if the (Ctrl + c) is pressed on keyboard without even selecting any text.
Inside this function, the Copied variable is set to TRUE, which will be later displayed on the page using SPAN element.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<script type="text/javascript">
    var app = angular.module('MyApp', [])
    app.controller('MyController', function ($scope) {
        // By default false.
        $scope.Copied = false;
        $scope.Copy = function () {
            // Set to true.
            $scope.Copied = true;
        }
    });
</script>
