我是靠谱客的博主拼搏大树，最近开发中收集的这篇文章主要介绍JS提交并解析后台返回的XML的代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

<SCRIPT LANGUAGE="JavaScript"> 
<!-- 
function createRequestObject() { 
try { 
xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); //for IE explorer 
usewin = "msxml"; 
} 
catch(e) { 
try { 
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); //for IE 
usewin = "microsoft"; 
} 
catch(e) { 
try{ 
xmlhttp=new XMLHttpRequest();}catch(e){} //for Mozilla 
} 
} 
if(!xmlhttp&&typeof XMLHttpRequest!="undefined") { //object is null 
xmlhttp=new XMLHttpRequest(); 
usewin = "undefined"; 
} 
return xmlhttp; 
} 
function sendRequest() { 
try{ 
var url="/xxxxx.xxx?para_1="xxx"¶_2="xxxx"; 
xmlhttp.open("GET", url, true); 
xmlhttp.setRequestHeader('Content-Type', "text/xml"); //set request type (xml) 
xmlhttp.onreadystatechange = handleResponse; //if state changed, function handleResponse called 
xmlhttp.send(null); //send request 
} 
catch(e){ 
alert('Request send failed.'); 
} 
finally{} 
} 


function handleResponse() //state changed 
{ 
try { 
if((xmlhttp.readyState == 4)&&(xmlhttp.status == 200)){ //Received success 
var response = xmlhttp.responseXML.documentElement; //get response obj 
var node_ = response.getElementsByTagName('user'); //example 
var s=""; 
var grouplist=document.getElementById("guserlist");//example 
var objX=null; 

for(var i=0;i<node_.length;i++) { 
var s1=node_[i].childNodes[0].childNodes[0].nodeValue; //id --example 
var s2=node_[i].childNodes[1].childNodes[0].nodeValue; //name --example 
objX=new Option(s2,s2); 
grouplist.options[document.scugroupsmodform.guserlist.length]=objX; 
} 
} 
}catch(e){ 
alert('Response failed.'); 
} 
finally{} 
} 
//--> 
</SCRIPT>
