这里我试图将“$ scope.getCourse ='adobe'”的值传递给服务器,以便它返回相应的课程详细信息,从中我可以使用响应数据中的ng-repeat填充列表。但是当我插入“$ scope.getCourse”和servelet url时,下面的代码失败了。
var courseApp = angular.module('courseApp', []); courseApp.controller('courseCtrl', ['$scope', '$http', function($scope, $http){ //$scope.getCourse = 'adobe'; //need to pass this value to the server; $http.post('javaServerlet', $scope.getCourse).success(function(data){ $scope.result = data.MainTopic; $scope.lessons = data.CourseOutline; }) }])
来自servelet的json格式
{ "MainTopic": "Adobe", "RunningTime": "6h11min", "Description": "Course Description comes here", "CourseOutline": [ { "Lessons" : "Lesson 1" , "Title" : "Introduction1" , "Duration" : "31m 27s"}, { "Lessons" : "Lesson 2" , "Title" : "Introduction2" , "Duration" : "56m 05s"}, ] }
请让我知道如何实现上述情况,我对angularjs很新。

您的data
应该是键/值对,请尝试:
$http.post('javaServerlet', {course: $scope.getCourse})
该变量将在参数course
