window、document、html、body、element的事件属性比较_html/css_WEB-ITnose

　　在分析jQuery的事件的时候有提到绑定事件的方式：

Dean Edwards的跨浏览器事件绑定使用的方式是

element["on" + type] = handleEvent;

　　即绑定的事件的前提条件是element.onxxx属性必须存在。

jQuery的绑定方式是使用浏览器的绑定绑定方法

if ( elem.addEventListener ) {　　elem.addEventListener( type, eventHandle, false );} else if ( elem.attachEvent ) {　　elem.attachEvent( "on" + type, eventHandle );}

　　为什么不用Dean Edwards使用的方式来绑定？

原因：

　　并非所有浏览器支持的事件都有对应的["on" + type]属性。比较典型的例子动画事件

<br /><p>该实例使用了 addEventListener() 方法为 DIV 元素添加"animationstart", "animationiteration" 和 "animationend" 事件。</p><div id="myDIV" >点我开始动画</div><script>var x = document.getElementById("myDIV")//存在onclick属性x.onclick = myFunction;// 使用 JavaScript 开始动画function myFunction() { //x.style.WebkitAnimation = "mymove 4s 2"; // Chrome, Safari 和 Opera 代码    x.style.animation = "mymove 4s 2";}//  Chrome, Safari 和 Opera//x.addEventListener("webkitAnimationStart", myStartFunction);//x.addEventListener("webkitAnimationIteration", myIterationFunction);//x.addEventListener("webkitAnimationEnd", myEndFunction);x.addEventListener("<strong>animationstart</strong>", myStartFunction);x.addEventListener("<strong>animationiteration</strong>", myIterationFunction);x.addEventListener("<strong>animationend</strong>", myEndFunction);function myStartFunction() {    this.innerHTML = "animationstart 事件触发 - 动画已经开始";    this.style.backgroundColor = "pink";}function myIterationFunction() {    this.innerHTML = "animationiteration 事件触发 - 动画重新播放";    this.style.backgroundColor = "lightblue";}function myEndFunction() {    this.innerHTML = "animationend 事件触发 - 动画已经完成";    this.style.backgroundColor = "lightgray";}</script>

　　上面的例子在IE10+、webkit4.0+内核浏览器（chrome、Opera、safari)、Firefox16.0+都能正常运行。但是如果将动画的绑定事件换成

x.onanimationstart = myStartFunction;x.onanimationiteration = myIterationFunction;x.onanimationend = myEndFunction;

　　三个动画函数没有任何一个能够正常运行。

　　所以现在明白jQuery为什么使用原生的事件绑定方法了吧。

　　

　　document.documentElement即html标签的DOM对象

　　document.body即body标点的DOM对象

 　　以chrome/IE8/IE9/firefox为例，简易的比较一下window、document、html、body、element的onxxx属性

　　说明：表格中yes表示对象拥有该属性，否则没有

　　chrome浏览器的事件基本都都列在上面了，基本上每个事件都有.onxxx属性，连animationend这样的HTML5新事件都包含在里面了，不过需要加webkit前缀。除了一下几个比较特殊的以外：

　　没有onfocusin，但是支持focusin事件

　　没有onfocusout，但是支持focusout事件

　　不支持打印事件:onafterprint、onbeforeprint

　　Safari 3.1 到 6.0 版本才支持transitionend事件, 使用webkitTransitionEnd来绑定
