在ajax中用POST方法提交的XML串，服务器端如何回显到客户端？
符上原代码：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN ">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<META NAME= "Generator " CONTENT= "EditPlus ">
<META NAME= "Author " CONTENT= " ">
<META NAME= "Keywords " CONTENT= " ">
<META NAME= "Description " CONTENT= " ">
</HEAD>
<script>
var xmlhttp;
function createXmlRequest(){
if(window.ActiveXObject){
xmlhttp=new window.ActiveXObject( "Microsoft.XMLHTTP ");
}else{
if(window.XMLHttpRequest){
xmlhttp=new XMLHttpRequest();
}else{
alert( "error ");
}
}
var url= "postxml.php? "+new Date().getTime();
xmlhttp.open( "POST ",url,true);
xmlhttp.setRequestHeader( "Content-Type ", "application/x-www-form-urlencoded; ");
xmlhttp.onreadystatechange=show;
xmlhttp.send(createXml());
}
function createXml(){
var xml= " <pets> ";
var options=document.getElementById( "petTypes ").childNodes;
var option=null;
for(var i=0;i <options.length;i++){
option=options[i];
if(option.selected){
xml=xml+ " <type> "+option.value+ " </type> ";
}
}
alert(xml+ " </pets> ");
return xml+ " </pets> ";
}
function show(){
if(xmlhttp.readyState==4){
if(xmlhttp.status==200){
var response=document.getElementById( "response ");
if(response.hasChildNodes()){
response.removeChild(response.childNodes[0]);
}
document.getElementById( "response ").appendChild(document.createTextNode(xmlhttp.responseText));
}
}
}
</script>
<BODY>
<h1> select OPtion </h1>
<form action= "# ">
<select name= "s " id= "petTypes " multiple >
<option value= "a "> afds </option>
<option value= "子子子 "> 子子子 </option>
<option value= "ccc "> cccc </option>
<option value= "声东击西test "> 声东击西test </option>
</select>
<input type= "button " value= "XMLPOST " onclick= "createXmlRequest(); ">
</form>
Server response
<div id= "response "> test </div>
</BODY>
</HTML>
[解决办法]
客户端:下面这个函数里面应该添加接收后的处理.
function show(){
if(xmlhttp.readyState==4){
if(xmlhttp.status==200){
var return_value = xmlhttp.responseXML;
//然后你再对返回的这个值进行处理.
}
}
服务器端:postxml.php中
根据你所获取的参数进行输出一个XML格式的东西.
我也是刚接触.如有不对,敬请谅解.
