In this article I will explain with an example, how to use ng-mousedown 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.
Button – For capturing user input.
The HTML INPUT Button has been assigned with the following AngularJS directive.
ng-mousedown – Called when the mouse button is clicked.
SPAN – For displaying message.
<div ng-app="MyApp" ng-controller="MyController">
    <input type="button" ng-mousedown="SetCount()" value="Increment" />
    <hr />
    Count: <span style="font-weight:bold">{{Count}}</span>

Implementing ng-mousedown Directive

Inside the HTML Markup, the following AngularJS script file is inherited:
1. angular.min.js
Then, inside the Controller, the Count variable is set to Zero.
When the mouse button is clicked, the SetCount function is called.
Inside this function, the Count variable is incremented by 1, which will be latter displayed on the page using SPAN element.
<script type="text/javascript" src=""></script>
<script type="text/javascript">
    var app = angular.module('MyApp', [])
    app.controller('MyController', function ($scope) {
        // By default Count is zero.
        $scope.Count = 0;
        $scope.SetCount = function () {
            // Increment the Count by one.
