今天學(xué)習(xí)了一下Angular中ng-options下拉數(shù)據(jù)默認(rèn)值的設(shè)定方法，留個(gè)筆記

直接上代碼

    <div class="form-group">        <label class="col-sm-2 control-label">教師</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="">選擇教師</option>               </select>             </div>      </div>

AngularJS

    //data為課程的編號(hào)ID   $scope.Edit = function (data) {      //通過課程ID獲取課程對(duì)象      CourseService.getByCourseID(data).then(function (result) {        $scope.editCourse = result.data;        //默認(rèn)值設(shè)定        //先通過課程里面的教師ID獲取教師對(duì)象        CourseService.GetTeacherByTeacherID(result.data.TeacherID).then(function (result) {         //$scope.TeacherList為所有教師的列表          for (i = 0; i < $scope.TeacherList.length; i++) {            //如果當(dāng)前課程教師的ID與當(dāng)前遍歷到的教師的ID相等的話就把當(dāng)前遍歷到的這個(gè)教師的對(duì)象給到 ng-model="editCourse.TeacherName"            if (result.data.UserID == $scope.TeacherList[i].UserID) {              $scope.editCourse.TeacherName = $scope.TeacherList[i];            }          }        });        angular.element("#edit").modal({          show: true        })      })    }
