在分析jQuery的事件的時候有提到綁定事件的方式：
Dean Edwards的跨瀏覽器事件綁定使用的方式是
element["on" + type] = handleEvent;
即綁定的事件的前提條件是element.onxxx屬性必須存在。
jQuery的綁定方式是使用瀏覽器的綁定綁定方法
if ( elem.addEventListener ) { elem.addEventListener( type, eventHandle, false ); } else if ( elem.attachEvent ) { elem.attachEvent( "on" + type, eventHandle ); }
爲什麼不用Dean Edwards使用的方式來綁定？
原因：
並非所有瀏覽器支持的事件都有對應的["on" + type]屬性。比較典型的例子動畫事件
<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>該實例使用了 addEventListener() 方法爲 DIV 元素添加"animationstart", "animationiteration" 和 "animationend" 事件。</p> <div id="myDIV" >點我開始動畫</div> <script> var x = document.getElementById("myDIV") //存在onclick屬性 x.onclick = myFunction; // 使用 JavaScript 開始動畫 function myFunction() { //x.style.WebkitAnimation = "mymove 4s 2"; // Chrome, Safari 和 Opera 代碼 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 事件觸發 - 動畫已經開始"; this.style.backgroundColor = "pink"; } function myIterationFunction() { this.innerHTML = "animationiteration 事件觸發 - 動畫重新播放"; this.style.backgroundColor = "lightblue"; } function myEndFunction() { this.innerHTML = "animationend 事件觸發 - 動畫已經完成"; this.style.backgroundColor = "lightgray"; } </script>
上面的例子在IE10+、webkit4.0+內核瀏覽器（chrome、Opera、safari)、Firefox16.0+都能正常運行。但是如果將動畫的綁定事件換成
x.onanimationstart = myStartFunction; x.onanimationiteration = myIterationFunction; x.onanimationend = myEndFunction;
三個動畫函數沒有任何一個能夠正常運行。
所以現在明白jQuery爲什麼使用原生的事件綁定方法了吧。
document.documentElement即html標籤的DOM對象
document.body即body標點的DOM對象

chrome瀏覽器的事件基本都都列在上面了，基本上每個事件都有.onxxx屬性，連animationend這樣的HTML5新事件都包含在裏面了，不過需要加webkit前綴。除了一下幾個比較特殊的以外：
沒有onfocusin，但是支持focusin事件
沒有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來綁定

Firefox有幾個比較特殊的地方：
沒有onfocusin，也不支持focusin事件
沒有onfocusout，也不支持focusout事件
沒有onsearch,也不支持該事件
沒有onanimationend，但是支持animationend事件
沒有onanimationiteration，但是支持animationiteration事件
沒有onanimationstart，但是支持animationstart事件
沒有ontransitionend，但是支持transitionend事件
已廢棄onmousewheel
沒有onstorage
沒有ontoggle，也不支持toggle事件
到此爲止了，花費的時間不少，算是一個各個瀏覽器差別的筆記，比較粗略，實際上每個瀏覽器不同版本會有一些細微差別，不過有這這個大概的目錄以後會比較容易查找不同。以後項目中如果遇到有onxxx事件綁定的問題有個參考。
