请教AJAX后台代码C#的
我的前台代码已经写好了是一个严整码的程序,请高手指教下小弟跪谢.
我的前台是:
<html>
<head>
<title> </title>
<meta name= "GENERATOR " content= "Microsoft Visual Studio .NET 7.1 ">
<meta name=ProgId content=VisualStudio.HTML>
<meta name=Originator content= "Microsoft Visual Studio .NET 7.1 ">
<script language=javascript>
var xmlhttp;
function createXMLHttpRequest()
{
if(window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
if(window.ActiveXObject)
{
xmlhttp=new ActiveXObject( "Microsoft.XMLHTTP ");
}
}
function validate()
{
createXMLHttpRequest();
var date=document.getElementById( "birthDate ");
var url= "ValidationServlet.aspx?birthDate= "+eacape(date.value);
xmlhttp.open( "GET ",url,true);
xmlhttp.onreadystatechange=callback;
xmlhttp.open(null);
}
function callback()
{
if(xmlhttp.readyState==4)
{
if(xmlhttp.status==200 || xmlhttp.status==200)
{
var mes=xmlhttp.responseXML.getElementsByTagName( "message ")[0].firstChild.data;
var val=xmlhttp.responseXML.getElementsByTagName( "passed ")[0].firstChild.data;
setMessage(mes,val);
}
}
}
function setMessage(message,isValid)
{
var messageArea=document.getElementById( "dateMessage ");
var fontColor= "red ";
if(isValid== "true ")
{
fontColor= "green ";
}
messageArea.innerHTML= " <font Color= "+fontColor+ "> "+message+ " </font> ";
}
</script>
</head>
<body>
<h1> AJAX Validation Example </h1>
Birth date: <input type=text size=10 id=birthDate onchange=validate()>
<div id= "dateMessage "> </div>
</body>
</html>
------解决方案--------------------
不是有现成的框架么,何必呢
