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!
var canBubbleUp = { click: true, dblclick: true, keydown: true, keypress: true, keyup: true, mousedown: true, mousemove: true, mouseup: true, mouseover: true, mouseout: true, wheel: true, mousewheel: true, input: true, change: true, beforeinput: true, compositionstart: true, compositionupdate: true, compositionend: true, select: true, cut: true, paste:true, focusin: true, focusout: true, DOMFocusIn: true, DOMFocusOut: true, DOMActivate: true, dragend:true, datasetchanged:true}if (!W3C) { delete canBubbleUp.change delete canBubbleUp.select}//.... |
