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>
