告诉你怎样解决Ajax中文乱码问题
亿网
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
<%@ Page 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。
