AngularJS ng-click 停止传播 [英] AngularJS ng-click stopPropagation

问题描述

我在表格行上有一个点击事件，在这一行中还有一个带有点击事件的删除按钮.当我单击删除按钮时，该行上的单击事件也会被触发.

I have a click Event on a table row and in this row there is also a delete Button with a click Event. When i click the delete button the click Event on the row is also fired.

这是我的代码.

<tbody>
  <tr ng-repeat="user in users" class="repeat-animation" ng-click="showUser(user, $index)">
    <td>{{user.firstname}}</td>
    <td>{{user.lastname}}</td>
    <td>{{user.email}}</td>
    <td><button class="btn red btn-sm" ng-click="deleteUser(user.id, $index)">Delete</button></td>
  </tr>
</tbody>

如何防止在单击表格单元格中的删除按钮时触发 showUser 事件?

How can I prevent that the showUser Event is fired when i click the delete Button in the table cell?

推荐答案

ngClick 指令(以及所有其他事件指令)创建在相同范围内可用的 $event 变量.这个变量是对 JS event 对象的引用，可以用来调用 stopPropagation():

ngClick directive (as well as all other event directives) creates $event variable which is available on same scope. This variable is a reference to JS event object and can be used to call stopPropagation():

<table>
  <tr ng-repeat="user in users" ng-click="showUser(user)">
    <td>{{user.firstname}}</td>
    <td>{{user.lastname}}</td>
    <td>
      <button class="btn" ng-click="deleteUser(user.id, $index); $event.stopPropagation();">
        Delete
      </button>
    </td>              
  </tr>
</table>
