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> |
