  • ng-if展开收起列表

    用ng-if判断当displayMore值为false时列表状态为收起状态,显示的按钮为展开按钮;

    当displayMore的值为true时列表状态为展开状态,显示的按钮为收起按钮;

    html代码:

     1 <div class="edit-template-column">
     2     <div layout="row" layout-align="space-between center" class="margin-bottom-10">
     3         已选中的列(可对列进行拖动排序):
     4         <a style="color: #A2A2A2;" ng-if="$ctrl.displayMore"
     5            ng-click="$ctrl.changeDisplayMore()">
     6             <i class="glyphicon glyphicon-chevron-up"></i>
     7             收起
     8         </a>
     9         <a style="color: #A2A2A2;" ng-if="!$ctrl.displayMore"
    10            ng-click="$ctrl.changeDisplayMore()">
    11             <i class="glyphicon glyphicon-chevron-down"></i>
    12             展开
    13         </a>
    14     </div>
    15     <!--站点-->
    16     <table class="table table-bordered table-list table-striped no-margin-bottom">
    17         <thead>
    18         <tr>
    19             <th width="60" class="text-center">排序</th>
    20             <th>列名</th>
    21             <th width="100">主键</th>
    22             <th width="100">必填</th>
    23         </tr>
    24         </thead>
    25         <tbody data-ng-model="table.ListColumn" as-sortable>
    26         <tr ng-repeat="selectedColumn in table.ListColumn"
    27             ng-if="!$ctrl.displayMore && $index<4 || $ctrl.displayMore" as-sortable-item>
    28         //设置展开收起的内容
    29             <td class="text-center">
    30                 <md-icon class="material-icons step icon-24-999"
    31                          ng-bind="' open_with'" as-sortable-item-handle>
    32                 </md-icon>
    33             </td>
    34             <td>{{selectedColumn | columnTranslateFilter}}</td>
    35             <td><span ng-if="selectedColumn.IsPrimaryKey">{{'true' | translate}}</span></td>
    36             <td><span ng-if="selectedColumn.IsRequired">{{'true' | translate}}</span></td>
    37         </tr>
    38         </tbody>
    39     </table>
    40 </div>
    JS代码:
    var self = this//定义初始状态为收起状态
    self.displayMore = false;
    self.changeDisplayMore = function () {
       self.displayMore = !self.displayMore
    };
