angularjs鼠标移入移出实现显示隐藏

Posted 2020-10-30 mini_fan

<tr ng-repeat="item in items track by $index">
    <td data-title="操作" align="center" ng-mouseenter="$parent[\'buttonList\'+$index] = true" ng-mouseleave="$parent[\'buttonList\'+$index] = false">
          <div ng-show="!$parent[\'buttonList\'+$index]">操作</div>
           <div ng-show="$parent[\'buttonList\'+$index]">
                  <button class="btn btn-primary fa fa-download"></button>
                  <button class="btn btn-success fa fa-reply"></button>
                  <button class="btn btn-primary fa fa-edit"></button>
                  <button class="btn btn-danger fa fa-trash"></button>
             </div>          
    </td>
</tr>

　　主要是ng-mouseenter和ng-mouseleave配合使用，同时注意$parent实现动态拼接变量
