在同一个受控变量中获取 $scope.data 的值 [英] get the value of $scope.data in a variable in same controlled

问题描述

我的代码有点东西

        $scope.data = {};
        var init = function () {
            $http.post('views/Report.aspx/GetMailReport', {})
            .success(function (data, status, headers, config) {
                $scope.data = JSON.parse(data.d);
            })
            .error(function (data, status, headers, config) {
                $scope.data = status;
            })
        };
        init();

        var data = $scope.data;

但 var 数据返回空 {}

But the var data is returning empty {}

推荐答案

如果你想要一个副本，你应该按照下面的方式做... 由于 http 调用是异步的，你在成功回调方法中分配

If you want a copy you should do as below... As the http call is asynchronous you assign inside the success callback method

$scope.data = {}; 
var data;

var init = function () {           
  $http.post('views/Report.aspx/GetMailReport', {}) .success(function (data, status, headers, config) {
  $scope.data = JSON.parse(data.d); 
data = $scope.data;
}) .error(function (data, status, headers, config) { 
  $scope.data = status; 
}) }; 
init();
