一个html标记中attribute的集合怎么取

[madpc]

我用attributes属性,发现会取出一大堆,我只要在html中写出来的

[xinyung]

可以这样去取

function getAttributes(obj) {
	var attributes = new Array();
	var allAttr = obj.attributes;
	var attrValue;
	var j = 0;
	for (var i in allAttr) {
		attrValue = obj.getAttribute(i);
		if (attrValue != null && attrValue != "" && attrValue != "inherit")
			attributes[j++] = i;
	}
	return attributes;
}

<img src="aaa.gif" alt="img" id="img1" />
<script>
    var img = document.getElementsByTagName("img")[0];
    var html = img.outerHTML;
    var re = /(\w+)[\s]*=[\s]*("[^"]+"|[^\s]+)/g;
    html.replace(re,function(s){
       if(s!=html){
	  var arr=s.split("=")
          alert(arr[0]+":"+arr[1]);
       }
    });
</script>
