javascript - 为什么我在 Angular JS 中使用解析时出现错误？

Question

我正在尝试使用resolve。这意味着我需要在加载 Controller 和 View 之前从服务获取数据。我找到了一些如何使用resolve的行。

当我删除解析语句时，我的项目中没有出现错误

.state('a', {
      url: "/a",
      templateUrl: "a.html",
          controller: 'a',
          // resolve:{
          //   messsage:function(testservice){
          //     return testservice.getdata();
          //   }
          //}
      })

当我取消注释解析语句时，出现此错误

我正在尝试在 Controller 中使用之前和加载查看之前从服务加载数据

Answer 1

为您的服务使用良好的语法

factory('testservice', ['$http',
    function testservice($http) {

获取 Controller 中的数据:

$scope.data = testservice.getdata();

那么您应该考虑在服务中备份您的数据，以便您调用 $http.get("data.json") 一次。
