AngularJS中如何使用$http对MongoLab数据表进行增删改查
主页面:
<buttonng-click="loadCourse()">LoadCourse</button> <buttonng-click="toggleAddCourse(true)">AddNewCourse</button> <ng-includcesrc="'course_list.html'"></ng-include> <ng-includesrc="'add_course.html'"ng-show="toggleAddCourseView"></ng-include> <ng-includesrc="'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。
