AngularJs ng-mouseleave Example

What is ng-mouseleave directive? Why we use it?

The ng-mouseleave is used to specify to perform the custom behaviour on mouse leave event.

If you want to add and fire a mouse leave event on HTML button that time we need to use these events.

When you mouse leave on focused button in the below example, the ngMouseleave function get called.

As you can see in the below controller function "mouseleave" get called after ngMouseleave on button.

The example as,

//The HTML Code sample
<button ng-mouseleave="mouseleave(IsActive)"> NG-MOUSELEAVE</button> 

//The AngularJs Code sample
var app = angular.module('myApp', []);
app.controller('ngClickCtrl', function ($scope) {
            $scope.firstName = "Anil";
            $scope.lastName = "Singh";
            $scope.IsActive = false;

            $scope.mouseleave = function (IsActive) {
                if (!IsActive) {
                    $scope.IsActive = true;
                } else {
                    $scope.IsActive = false;
                }
            };
});
