You can pass the $event object as an argument when calling the function.
The $event object contains the browser‘s event object:
<div ng-app="myApp" ng-controller="myCtrl">
<h1 ng-mousemove="myFunc($event)">Mouse Over Me!</h1>
<p>Coordinates: {{x + ‘, ‘ + y}}</p>
</div>
<script>
var app = angular.module(‘myApp‘, []);
app.controller(‘myCtrl‘, function($scope) {
$scope.myFunc = function(myE) {
$scope.x = myE.clientX;
$scope.y = myE.clientY;
}
});
</script>
