客户端代码：
var xmlHttp;
function createXMLHttpRequest(){
if(window.ActiveXObject){
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}else if (window.XMLHttpRequest){
xmlHttp = new XMLHttpRequest();
}
}
function sl(url){
//可加一些验证信息
document.getElementById('slform').style.display='';//打开受理form
//alert("url="+url);
createXMLHttpRequest();//为 xmlHttp 赋值
xmlHttp.open("GET", url, true);
xmlHttp.onreadystatechange = slcallback;
xmlHttp.send(null);
}
function slcallback(){
if (xmlHttp.readyState == 4) {
if (xmlHttp.status == 200) {
var applyPerson = xmlHttp.responseXML.getElementsByTagName('applyPerson')[0].firstChild.data;
var applyIdCard = xmlHttp.responseXML.getElementsByTagName('applyIdCard')[0].firstChild.data;
document.getElementById('slPerson').value=applyPerson;
document.getElementById('slId').value=applyIdCard;
}
}else{
}
}
在action里，返回到一个jsp页面，在jsp页面里把内容设为xml格式
如下：
<%@ page contentType="text/xml; charset=GBK"%>
<%
String applyPerson = (String)request.getAttribute("applyPerson");
String applyIdCard = (String)request.getAttribute("applyIdCard");
%>
<?xml version="1.0" encoding="GBK"?>
<response>
<applyPerson><%=applyPerson%></applyPerson>
<applyIdCard><%=applyIdCard%></applyIdCard>
</response>
