如题:
JavaScript 如何遍历得到控件的所有属性?

[是是非非]

for(var s in window){
alert('window.'+s+' = '+window[s]);
}

好,谢谢
还有.
如果这个属性对象还有属性,怎么遍历属性的属性.

即如何得到子属性的个数.

<span a=1 b=2 c=3 onclick="test(this)">点击查看我的属性集</span>
<br>
<br>
<div id=result></div>
<script>
function test( the )
{
var str = "" ;
for( var i = 0 ; i < the.attributes.length ; i++ )
{
str += "nodeName:" + the.attributes[ i ].nodeName + "<br>" ;
str += "nodeType:" + the.attributes[ i ].nodeType + "<br>" ;
str += "nodeValue:" + the.attributes[ i ].nodeValue + "<br>" ;
str += "name:" + the.attributes[ i ].name + "<br>" ;
str += "specified:" + the.attributes[ i ].specified + "<br>" ;
str += "expando:" + the.attributes[ i ].expando + "<br>" ;
str += "<br>---------------<br>"
}
result.innerHTML = str
}
</script>
