window、document、html、body、element的事件属性比较
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
<style>
#myDIV {
margin:25px;
width:550px;
height:100px;
background:orange;
position:relative;
font-size:20px;
}
/* Chrome, Safari, Opera */
@-webkit-keyframes mymove {
from {top: 0px;}
to {top: 200px;}
}
@keyframes mymove {
from {top: 0px;}
to {top: 200px;}
}
</style>
<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("animationstart", myStartFunction);
x.addEventListener("animationiteration", myIterationFunction);
x.addEventListener("animationend", 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

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

Firefox有几个比较特殊的地方：
没有onfocusin，也不支持focusin事件
没有onfocusout，也不支持focusout事件
没有onsearch,也不支持该事件
没有onanimationend，但是支持animationend事件
没有onanimationiteration，但是支持animationiteration事件
没有onanimationstart，但是支持animationstart事件
没有ontransitionend，但是支持transitionend事件
已废弃onmousewheel
没有onstorage
没有ontoggle，也不支持toggle事件
到此为止了，花费的时间不少，算是一个各个浏览器差别的笔记，比较粗略，实际上每个浏览器不同版本会有一些细微差别，不过有这这个大概的目录以后会比较容易查找不同。以后项目中如果遇到有onxxx事件绑定的问题有个参考。
