用户刷新页面时如何进行angularjs $ http POST调用？

Question

controller:

app.run(function ($rootScope, $templateCache) {
    $rootScope.$on('$viewContentLoaded', function ($scope, $http) {     
        $templateCache.removeAll();
        alert("refresh.....");
        $http({
            url: '/angularjs-restful/check/check-session',
            method: "POST",
            data: {},
            isArray: false
        }).success(function(data, status, headers, config){
            alert("success.....");
            console.log('status: ' + status);
            console.log('data: ' + data);
        }).error(function(data, status, headers, config){
            alert('error');
        });        
        alert("end.....");
    });       
});

I need to make an AJAX call when a user hit f5 on keyboard or manually refresh the page with a mouse. How can I achieve this? the url is a rest service that either return true or false.

Answer 1

you can use window.onbeforeunload function to listen to the unload event which should fire on f5.

function ctrl($scope, $window) {
    angular.element($window).bind('beforeunload', function() {
        console.log('do ajax call');
    });
}
