这是我的角度控制器
//Save AddNewEmployee functionality
EDC.SaveNewEmployee = function () {
if (EDC.AddNewEmployeeFormValidator.validate()) {
var UserID = '0',
CandidateSubmit = '';
if (EDC.isEdit) {
UserID = EDC.rowIdToEdit;
}
EmployeeDetailService.SaveNewEmployee(EDC.NewEmpAdd, UserID, CandidateSubmit).then(function (response) {
//Close popup window
EDC.AddNewEmployeeWindow.data("kendoWindow").close();
//EDC.NewEmpSave = response;
EDC.EmployeeDetailsGrid.dataSource.read();
});
}
};
这是我的MVC控制器。

通常javascript代码同步执行（默认），javascript有核心promise对象，用于使函数异步。
Angularjs有核心服务$ q，用于使函数异步。
Angularjs简单示例：
angular.module("starter", [])
.controller("myCtrl", function($scope, $q, $http){
var GetData = function(){
var root = 'https://jsonplaceholder.typicode.com';
var defer = $q.defer();
$http({
method: "GET",
url: root + '/posts/1'
}).then(function(response){
//success call back
defer.resolve(response);
}, function(error){
//error callbcall
defer.reject();
});
return defer.promise;
};
$scope.AsynchCall = function(){
GetData().then(function(response){
//success call back
console.log(response);
alert(JSON.stringify(response));
}, function(error){
//error callbcall
console.log(JSON.stringfy(error));
alert(error);
});
};
}); <html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body ng-app="starter" ng-controller="myCtrl">
<button ng-click="AsynchCall()"> Asynch call </button>
</body>

这是因为JSON.stringify将返回toJSON函数的返回值（如果存在）。
