angular 中ng-bind-html 、$scope服务

angularjs最强大之处之一，数据双向绑定。项目中常用到的两个是ng-bind和ng-model.

ng-bind 针对普通模块进行绑定、ng-model针对form表单进型绑定。

  <td>
                                            <input type="number" class="form-control" name="mobile" ng-model="newModel.mobile" ng-maxlength="11" />
                                            <span class="text-danger" ng-show="form.mobile.$dirty && form.mobile.$invalid">
                                                <small class="text-danger" ng-show="form.mobile.$error.maxlength">
                                                    <i class="fa fa-exclamation-triangle"></i> 移动电话不能超过11个字符
                                                </small>
                                            </span>
                                        </td>

 <span ng-if="selectedItems.length == 0" class="selected-items">
      <span ng-bind="defaultLabel"></span>
    </span>
    <span ng-if="selectedItems.length > 0" class="selected-items">
      <span ng-repeat="selectedItem in selectedItems" class="selected-item">{{selectedItem.name}} <span class="selected-item-close"
                                                                                  ng-click="deselectItem(selectedItem, $event)"></span></span>
        <!--<span class="caret"></span>-->
    </span>
