jQuery事件冒泡 [英] jQuery event bubbling
问题描述
我想了解如何解释冒泡。这是否意味着上升HTML代码层次结构或其他什么？
I want to understand how exactly to interpret bubbling. Does it mean going up the HTML code hierarchy or something else?
其次，我正在经历一个示例我无法理解它所说的最后一部分
Secondly, I was going through an example and I could not understand the last part where it says
基于P的点击处理程序侦听click事件，然后阻止它传播（冒泡）
The P-based click handler listens for the click event and then prevents it from being propagated (bubbling up)
这是什么意思？
推荐答案
return false;
将阻止冒泡。它用于停止默认操作，例如选中复选框，打开选择，点击等。
will prevent "bubbling". It's used to stop default actions like checking a checkbox, opening a select, a click, etc.
阻止更多处理程序在执行后执行使用.live（），
绑定处理程序必须返回false。调用.stopPropagation（）将不会
完成此操作。
To stop further handlers from executing after one bound using .live(), the handler must return false. Calling .stopPropagation() will not accomplish this.
推理（感谢@AlienWebguy）：
From Caveats in jQuery .live()
Reasoning (thanks to @AlienWebguy):
原因 stopPropagation（）不适用于 live（）是 live（）将事件绑定到文档，因此当它触发时，没有其它地方可以传播。
The reason stopPropagation() doesn't work with live() is that live() binds the event to document so by the time it fires there's no where else for it to propagate.
