没明白你的意思,但是我有,用ajax做登陆的代码,给你参考吧.
下面是通用js脚本:
// JScript 文件, 2006-05-15--chx
//用于ajax的公用操作
function createRequestObject() //创建XMLHttpRequest对象
{
var xmlhttp_request=null;
try{
if( window.ActiveXObject )
{
for( var i = 5; i; i-- )
{
try{
if( i == 2 )
{
xmlhttp_request = new ActiveXObject( "Microsoft.XMLHTTP" );
}
else
{
xmlhttp_request = new ActiveXObject( "Msxml2.XMLHTTP." + i + ".0" );
xmlhttp_request.setRequestHeader("Content-Type","text/xml");
xmlhttp_request.setRequestHeader("Content-Type","GB2312");
}
break;
}
catch(e)
{
xmlhttp_request=null;
}
}
}
else if( window.XMLHttpRequest )
{
xmlhttp_request = new XMLHttpRequest();
if (xmlhttp_request.overrideMimeType)
{
xmlhttp_request.overrideMimeType('text/xml');
//xmlhttp_request.overrideMimeType('GB2312');
}
}
}
catch(e)
{
xmlhttp_request=null;
}
return xmlhttp_request ;
}
//发送异步请求
function SendRequest(method,url,data,callback,isasyn)//callback该函数获取异步返回信息并显示,dada是字符串
{
var xmlhttp=createRequestObject();
with(xmlhttp)
{
try
{
// 加随机数防止缓存
if (url.indexOf("?") > 0)
{
url += "&randnum=" + Math.random();
}
else
{
url += "?randnum=" + Math.random();
}
open(method, url,isasyn);
// 设定请求编码方式
//setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=GB2312');
if(data!="")
{
send(data);
}
else
{
send();
}
onreadystatechange = function ()
{
if (xmlhttp.readyState == 4)//判断异步调用是否成功
{
callback(xmlhttp);
xmlhttp=null;
}
}
}
catch(e)
{
alert(e);
}
}
}
下面是实际代码:
<script type="text/javascript" src="../JScript/ajax.js"></script>
<script type="text/javascript">
var serid="";
function checkuser(object)
{
var thisid=object.id;
serid=thisid.substring(0,thisid.lastIndexOf('_'));
public_getElementByID(serid+"_ibtmLogin").style.display="none";
public_getElementByID("divlogin").innerHTML="正在登陆......<br/><img width='170' src='../Images/loader.gif'/>";
var user=public_getElementByID(serid+"_txtUserName").value;
var pass=public_getElementByID(serid+"_txtPassWord").value;
SendRequest("POST","../Pages/Check.aspx?loginuser="+user+"&pass="+pass+","",checkok,true);
}
function checkok(http)
{
var response = http.responseText; //返回服务器端生成的字符串
if(response=="登陆成功")
{
public_getElementByID("divlogin").innerHTML=response;
window.location.href="../Default.aspx"
return;
}
else
{
alert(response);
public_getElementByID(serid+"_ibtmLogin").style.display="block";
public_getElementByID("divlogin").innerHTML="";
}
}
</script>
说明:public_getElementByID()是我支持ec和ie 的方法,相当于document.getElementByID(). |
