js代码：
得到XmlHttpRequest的类
Code
function HttpRequest()
{
//取得Request对象
this.Request=function(){
try
{
if(window.XMLHttpRequest) request=new XMLHttpRequest();
if(!request)request=new ActiveXObject(Microsoft.XMLHTTP);
if(!request)request=new ActiveXObject(Msxml2.XMLHTTP);
return request;
}
catch(e)
{
alert(不支持XMLHTTPRequest);
}}
}
调用过程：
Code
<%@%u3000Page Language=C# AutoEventWireup=true CodeBehind=Default.aspx.cs Inherits=AjaxTest._Default %>
<!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd>
<html xmlns=http://www.w3.org/1999/xhtml>
<head runat=server>
<title>Untitled Page</title>
<script language=javascript type=text/javascript src=User.Base.js></script>
<script language=javascript type=text/javascript>
function Check()
{
var request=new HttpRequest().Request();
request.onreadystatechange=function (){
if(request.readyState==4)
{
if(request.status==200)
{
alert(request.responseText);
}
else
{
alert(request.responseText);
}
}
}
var value=document.getElementById(val).value;
request.open(POST,Default.aspx?Value= value,true);
//设置防止乱码的方法，只要一句话就行
request.setRequestHeader(Content-Type,text/html;charset=gb2312);
request.send(null);
}
</script>
</head>
<body>
<form id=form1 runat=server>
<div>
<input id=val type=text onblur=Check() />
</div>
</form>
</body>
</html>
后台取得输入值：
protected void Page_Load(object sender, EventArgs e)
{
string value = Request[Value];
}
测试过，可以得到正确的输入字符。
