AngularJS - 多次ng-click - 事件冒泡

Question

在以下示例中:

  <li ng-repeat="item in items" ng-click="showItem(item)">
    <h3>{{item.title}}</h3>
    <button ng-click="remove(item)">Remove</button>
  </li>

当我点击按钮时,showItem()由于事件冒泡也会调用它.我知道我可以$event用来观察$event.currentTarget和做$event.stopPropagation()等等,但这非常难看.

顺便说一句.我不想停止传播button(在我的情况下button是一个twitter bootstrap dopdown/button- 这只是一个例子)

showItem()当我点击remove按钮时,如何停止调用？

编辑 丑陋的解决方案是:

function remove(item,$event){
  $event.originalEvent.prevent = true;
  // rest of the code
}

function showItem(item,$event){
  if($event.originalEvent.prevent)return;
  // rest of the code
}

这个解决方案对我有用(我只支持最近的浏览器,所以我尝试修改代码以更复古兼容):

HTML:

<li ng-repeat="item in items" ng-click="showItem(item)">
    <h3>{{item.title}}</h3>
    <button ng-click="remove(item, $event)">Remove</button>
</li>

脚本:

function remove(item, $event) {
    // do some code here

    // Prevent bubbling to showItem.
    // On recent browsers, only $event.stopPropagation() is needed
    if ($event.stopPropagation) $event.stopPropagation();
    if ($event.preventDefault) $event.preventDefault();
    $event.cancelBubble = true;
    $event.returnValue = false;
}
function showItem(item) {
    // code here
}
