Html页面
<html>
<head>
<title>Ajax小方法，使用方法</title>
<script language='javascript'>...
function Cfrlogname(ln)
...{
if (!checkByteLength(ln.value.trim(),4,20))
...{
alert('请输入4-20字符用户名!');
ln.focus();
return false;
}
var Webreq = new Ajax();
Webreq.Config.Result = "OkSuc";
Webreq.Config.Spn = document.all.logName_info;
Webreq.Config.SucInfo = "验证成功!";
Webreq.Config.FaildInfo = "对不起，验证失败!";
Webreq.Config.returnType = 'Compare';
Webreq.Config.Url = 'www.56best.cn';
Webreq.Action('editData.aspx?types='+ln.value.trim())
}
</script>
</head>
<body>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td><input type="text" name="logName" id="logName" runat="server" >
<input type="button" name="Submit" value="检查会员名" onclick="Cfrlogname(document.all.logName)"></td>
</tr>
<tr>
<td class="gray_2"><div id="logName_info"> </div></td>
</tr>
</table>
</body>
</html> 使的的后台代码是 .aspx.vb 里面
Sub Page_Load()sub Page_Load()
dim Str as string = Request.QueryString("types")
Response.Write("<zwd><result>OkSuc</result></zwd>")
end sub
============================================= 如果在这个页面（HTML）只使用一次这个AJAX方法，不会有问题 但是如果同时多次使用（就是在加载页面时，获取数据时），就会出错。 一般是最后一个使用这个AJAX方法的地方，才会正常显示数据，其他的不能显示。 请帮我看一下.
