Is the following example of onbeforeunload message straightforward as it gets?
Can it be shorter or easier? Is there a more AngularJS way vs having those window events?
angular.module('TestApp', [])
.factory('beforeUnload', function ($rootScope, $window) {
// Events are broadcast outside the Scope Lifecycle
$window.onbeforeunload = function (e) {
var confirmation = {};
var event = $rootScope.$broadcast('onBeforeUnload', confirmation);
if (event.defaultPrevented) {
return confirmation.message;
}
};
$window.onunload = function () {
$rootScope.$broadcast('onUnload');
};
return {};
})
.run(function (beforeUnload) {
// Must invoke the service at least once
});
function TestController($scope) {
$scope.$on('onBeforeUnload', function (e, confirmation) {
confirmation.message = "All data willl be lost.";
e.preventDefault();
});
$scope.$on('onUnload', function (e) {
console.log('leaving page'); // Use 'Preserve Log' option in Console
});
}
