JS:
//XML文档对象
var xmlDoc;
//载入XML文档
function loadxmlDocument(docName)
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.validateOnParse = false;
xmlDoc.load(docName);
if(xmlDoc.parseError.errorCode != 0) {
alert(showError(xmlDoc));
return(false);
}
return(xmlDoc);
}
//调用数据
function startload()
{
var option,id,jobname,fid;
xmlDoc = loadxmlDocument("XMLDoc/job.xml");
if(xmlDoc == null)
{
alert('您的浏览器不支持xml文件读取!请使用IE版本');
}
else
{
clearList();
var DeptXML = xmlDoc.getElementsByTagName("job");
//alert(DeptXML.length);
for (var i = 0 ; i < DeptXML.length ; i ++ )
{
id = DeptXML[i].childNodes[0].getAttribute("value");
jobname = DeptXML[i].childNodes[1].getAttribute("value");
fid = DeptXML[i].childNodes[2].getAttribute("value");
// option = new Option(jobname,jobname);

//二级分类
if (fid == "0")

}
}
}
}
}
}
function clearList()
{
var select1 = document.getElementById("sel1");
while (select1.childNodes.length >0)
{
select1.removeChild(select1.childNodes[0]);
}
}
HTML：
加载时候绑定数据
<body onload="startload()">
<form id="form1" runat="server">
<div>
<select id="sel1" name="sel1" multiple="multiple">
</select>
</div>
</form>
</body>
