ajaxreg.js代码如下：
var http_request=false;
function send_request(url){//初始化，指定处理函数，发送请求的函数
http_request=false;
//开始初始化XMLHttpRequest对象
if(window.XMLHttpRequest){//Mozilla浏览器
http_request=new XMLHttpRequest();
if(http_request.overrideMimeType){//设置MIME类别
http_request.overrideMimeType("text/xml");
}
}
else if(window.ActiveXObject){//IE浏览器
try{
http_request=new ActiveXObject("Msxml2.XMLHttp");
}catch(e){
try{
http_request=new ActiveXobject("Microsoft.XMLHttp");
}catch(e){}
}
}
if(!http_request){//异常，创建对象实例失败
window.alert("创建XMLHttp对象失败！");
return false;
}
http_request.onreadystatechange=processrequest;
//确定发送请求方式，URL，及是否同步执行下段代码
http_request.open("GET",url,true);
http_request.send(null);
}
//处理返回信息的函数
function processrequest(){
var mess
if(http_request.readyState==4){//判断对象状态

if(http_request.status==200){//信息已成功返回，开始处理信息
if(http_request.responseText=='exist')
mess="<font color=red>此用户名已经存在，请更换用户名！</font>";

return false;
}
else{

}
}
function pwdrecheck(obj){
