每个 event 都有一个event.bubbles属性，可以知道它可否冒泡。(ref：W3定义的Event Interface)

当然 W3 DOM Level 3 Events 的细则里已经附上这个表格了：

Event Type Bubbling phase
abort ✗
beforeinput ✔
blur ✗
click ✔
compositionstart ✔
compositionupdate ✔
compositionend ✔
dblclick ✔
error ✗
focus ✗
focusin ✔
focusout ✔
input ✔
keydown ✔
keyup ✔
load ✗
mousedown ✔
mouseenter ✗
mouseleave ✗
mousemove ✔
mouseout ✔
mouseover ✔
mouseup ✔
resize ✗
scroll ✔
select ✔
unload ✗
wheel ✔

还附上了 Legacy Events（旧浏览器支持的非标准遗留事件）的 bubble 属性。

Event Type Bubbling phase
DOMActivate ✔
DOMAttrModified ✔
DOMCharacterDataModified ✔
DOMFocusIn ✔
DOMFocusOut ✔
DOMNodeInserted ✔
DOMNodeInsertedIntoDocument ✗
DOMNodeRemoved ✔
DOMNodeRemovedFromDocument ✗
DOMSubtreeModified ✔
keypress ✔

H5 还定义了一些新事件：

  • media相关事件，都不冒泡

  • drag相关事件 dragstart 、 drag 、 dragenter 、 dragexit 、 dragleave 、 dragover 、 drop 、 dragend均冒泡

  • History相关事件：popstate，hashchange冒泡（从window开始……所以意义在哪里），pagetransition不冒泡

还有很多H5新事件，大多在草案阶段，就不一一翻开了。

此外，这里还有一个关于IE的事件列表,http://www.feiesoft.com/html/events.html

事件冒泡是我们实现事件代理（委托）的关键，在avalon1.6中，默认让能冒泡的事件都使用事件代理实现了！
