AngularJS中如何使用$http对MongoLab数据表进行增删改查
Darren Ji 人气:0主页面:
<button ng-click="loadCourse()">Load Course</button> <button ng-click="toggleAddCourse(true)">Add New Course</button> <ng-includce src="'course_list.html'"></ng-include> <ng-include src="'add_course.html'" ng-show="toggleAddCourseView"></ng-include> <ng-include src="'edit_course.html'" ng-show="toggleEditCourseView"></ng-include>
以上,页面上显示course_list.html,add_course.html和edit_course.html的内容显示与toggleAddCourseView和toggleEditCourseView值有关,而toggleAddCourseView和toggleEditCourseView值将通过方法来控制。

$scope.courses = []; var url = "https://api.mongolab.com/api/1https://img.qb5200.com/download-x/databases/my-academy/collections/course?apiKey=myAPIKey"; var config = {params: {apiKey: "..."}}; $scope.toggleAddCourseNew = false; $scope.toggleEditCourseView = false; //列表 $scope.loadCourses = function(){ $http.get(url, config) .success(function(data){ $scope.courses = data; }); } //添加 $scope.addCourse = function(course){ $http.post(url, course, config) .success(function(data){ $scope.loadCourses(); }) } //显示修改 $scope.editCourse = function(course){ $scope.toggleEditCourseView = true; $scope.courseToEdit = angular.copy(course); } //修改 $scope.updateCourse = function(courseToEdit){ var id = courseToEdit._id.$oid; $http.put(url + "/" + id, courseToEdit, config) .success(fucntion(data){ $scope.loadCourses(); }) } //删除 $scope.delteCourse = function(course){ var id = course._id.$oid; $http.delete(url+ "/" + id, config) .success(function(data){ $scope.loadCourses(); }) } $scope.toggleAddCourse = function(flag){ $scope.toggleAddCourseView = flag; } $scope.toggleEditCourse = fucntion(flag){ $scope.toggleEditCourseView = flag; }
course_list.html 列表
<tr ng-repeat="course in courses"> <td>{{$index+1}}</td> <td>{{course.name}}</td> <td>{{course.category}}</td> <td>{{course.timeline}}</td> <td>{{course.price | currency}}</td> <td><button ng-click="editCourse(course)">Edit</button></td> <td><button ng-click="deleteCourse(course)">Delete</button></td> </tr>
