### 返回值:Objectevent.stopPropagation()
### *V1.0*概述
防止事件冒泡到DOM樹上，也就是不觸發的任何前輩元素上的事件處理函數。
我們可以用?[event.isPropagationStopped()](#)?來確定這個方法是否(在那個事件對象上)調用過了。
這個方法對?[trigger()](#)?來自定義的事件同樣有效。
注意，這不會阻止*同一個元素上*的其它事件處理函數的運行。
# Additional Notes:
自從[.live()](http://api.jquery.com/live)方法處理事件一旦傳播到文檔的頂部，live事件是不可能停止傳播的。同樣地，[.delegate()](http://api.jquery.com/delegate)?事件將始終傳播給其中包含的被委托元素；元素上的事件將在被委托事件被調用的時候執行。
### 示例
#### 描述:
滅掉click事件的冒泡。
##### jQuery 代碼:
~~~
$("p").click(function(event){
event.stopPropagation(); // do something
});
