function createXmlHttpRequest()

}
var xmlHttpRequest = createXmlHttpRequest();
function openWindow(windowDiv)

if(xmlHttpRequest.readyState==4 &&xmlHttpRequest.status==200)
{
var response = xmlHttpRequest.responseText;
alert(response);
windowDiv.innerHTML=response;
response=null;
url=null;
windowDiv=null;
}
}
//xmlHttpRequest.open("post",url,true);
//xmlHttpRequest.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
//xmlHttpRequest.send("name=在&password=12346");
xmlHttpRequest.open("get","test.html",true);
xmlHttpRequest.send();
}
我整个项目都是用GBK编码,如果test.html中有中文就会出现乱码,求救!!!

private string escape(string value)
{
StringBuilder sb = new StringBuilder();
byte[] ba = System.Text.Encoding.Unicode.GetBytes(value);
for (int i = 0; i < ba.Length; i += 2)
{
sb.Append("%u");
sb.Append(ba[i + 1].ToString("X2"));
sb.Append(ba[i].ToString("X2"));
}
return sb.ToString();
}
在后台进行编码处理
前台的时候用unescape进行解码吧，这样不会出现乱码问题
这个功能我大概描述下，当面页面有一个DIV，通过回调var response = xmlHttpRequest.responseText;就可以获得test.html页的代码，原后windowDiv.innerHTML=response; 放进DIV里去,test.html有中文就出现乱码了。
解决编码问题，一般返回字节流即可，然后转换，可以用responseBody属性
