Angular中ng-options下拉数据默认值的设定方法
FutaoSmile丶 人气:0今天学习了一下Angular中ng-options下拉数据默认值的设定方法,留个笔记
直接上代码
<div class="form-group"> <label class="col-sm-2 control-label">教师</label> <div class="col-sm-10"> <select style="display:block; width:100%; height:34px; padding:6px 12px; font-size:14px; line-height:1.4; border-radius:4px; border:1px solid #ccc; color:#555; " ng-model="editCourse.TeacherName" ng-options="Teacher.UserName for Teacher in TeacherList" required> <option value="">选择教师</option> </select> </div> </div>
AngularJS
/https://img.qb5200.com/download-x/data为课程的编号ID $scope.Edit = function (data) { //通过课程ID获取课程对象 CourseService.getByCourseID(data).then(function (result) { $scope.editCourse = result.data; //默认值设定 //先通过课程里面的教师ID获取教师对象 CourseService.GetTeacherByTeacherID(result.data.TeacherID).then(function (result) { //$scope.TeacherList为所有教师的列表 for (i = 0; i < $scope.TeacherList.length; i++) { //如果当前课程教师的ID与当前遍历到的教师的ID相等的话就把当前遍历到的这个教师的对象给到 ng-model="editCourse.TeacherName" if (result.data.UserID == $scope.TeacherList[i].UserID) { $scope.editCourse.TeacherName = $scope.TeacherList[i]; } } }); angular.element("#edit").modal({ show: true }) }) }
