写法1：
<html> <head> <title></title> <script language="javascript" type="text/javascript"> function dbClick() { alert(2); } function attClick() { alert(1); } function load() { var b = document.getElementById('mytd'); b.attachEvent("onclick", attClick); } </script> </head> <body id="mybody" onload="load();" > <table><tr><td ><a id="mytd" onclick="javascript:dbClick();">hello world!</a> </td></tr></table> </body> </html>
写法2：
<html> <head> <title></title> <script language="javascript" type="text/javascript"> window.attachEvent("onload", load); function dbClick() { alert(2); } function attClick() { alert(1); } function load() { var b = document.getElementById('mytd'); b.attachEvent("onclick", attClick); } </script> </head> <body id="mybody" > <table><tr><td ><a id="mytd" onclick="javascript:dbClick();">hello world!</a> </td></tr></table> </body> </html>
attachEvent的事件处理函数执行顺序
<script> window.attachEvent("onload",function(){alert('a')}); window.attachEvent("onload",function(){alert('b')}); window.attachEvent("onload",function(){alert('c')}); </script> <body onload=alert('x')> </body>
下面这段代码触发是在 <body onload=alert('x')> 之后才触发的。
window.attachEvent("onload",function(){alert('a')});
window.attachEvent("onload",function(){alert('b')});
window.attachEvent("onload",function(){alert('c')});
