javascript实现爱你在FF IE下都有效的添加一个项目

IE不是很乖,在IE里setAttribute只认一些静态属性,而像ONCLICK事件时无效的,要用attchEvent方法

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> 
<title>无标题文档</title> 
</head> 
<script type="text/javascript"> 
var elementCount=0; 
function mycreateElement(element,tag) 
{ 
    elementCount++; 
    var parentElement=element; 
    var count=elementCount; 
    var childElement=document.createElement(tag); 
    setProperty(childElement,"type","text"); 
    setProperty(childElement,"id","input" + elementCount) 
    var delElement=document.createElement("input"); 
    setProperty(delElement,"type","button"); 
    setProperty(delElement,"value","删除"); 
    setProperty(delElement,"id","delButton" + elementCount) 
    if(navigator.appName=="Microsoft Internet Explorer") 
    delElement.attachEvent("onclick",function(){del(count)}) 
    else 
    setProperty(delElement,"onclick","del(" + elementCount + ")"); 
    var wrap=document.createElement('div') 
    setProperty(wrap,"id","div" + elementCount) 
    wrap.appendChild(childElement); 
    wrap.appendChild(delElement); 
    parentElement.appendChild(wrap) 
} 
function setProperty(element,tag,property) 
{ 
    var element1=element; 
    element1.setAttribute(tag,property); 
} 
function del(elementCount1) 
{ 
    var parentNode=document.getElementById("mycontent"); 
    var divNode=document.getElementById("div" +elementCount1); 
    parentNode.removeChild(divNode); 
} 
</script> 
<body> 
<div> 
</div> 
<input type="button" value="增加" onClick="mycreateElement(document.getElementById('mycontent'),'input')"> 
</body> 
</html>
