Hi,
My problem is if a user enters a date in text box(dd-MMM-YYYY) format then the entered date must be after the current system date else an alert box must be raised.

The code that i have written is


<HTML><head>
<link rel="stylesheet" type="text/css" href="./managchpass.css" />
<script>
function fun()
{
var flag1=0;
var s6=document.f1.T3.value;
var s7=document.f1.date.value;
if(s6=="")
{
window.alert("Enter CloseDate");
flag7=0;
}
else if((s6.after(s7)) || (s6.equals(s7)))
{
flag7=1;
}
else
{
flag7=0;
window.alert("Enter correct date which is after current date");
}

if(flag1)
return true;
else
return false;
}
</script>

</head>
<body text="black" >

<FORM name=f1 method="post" action="./msurveydisp" onsubmit="return fun()">
<CENTER><B><u><FONT size=6 face="monotype corsiva">Create Poll</u></b> <br>


<%@page import="java.lang.*,javax.servlet.*,java.io.*,java.util.*,javax.servlet.http.*,java.sql.*"%>

<%
java.util.Date d=new java.util.Date();

DateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");
Format f = new SimpleDateFormat("dd-MMM-yyyy");

f.format(d);

%>

<table>
<TR>
<td>

ENTER THE CLOSING DATE OF THE
POLL<INPUT type=text name="T3"></td></tr>

</TABLE>
<input type="hidden" name="date" value="<%=f.format(d)%>">
<input type="image"
src="C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\prath\submit.jpg">

<a href="managesurvey.html">
<img src="C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\prath\back.jpg" border="0"></a>
</FORM></B>
</BODY>
</HTML>



Please help in solving this problem

This is not JavaScript: else if((s6.after(s7)) || (s6.equals(s7))) unless you extended the String Object

hi.... why are you making code so difficult.. this problem is very simple. you have to write only few lines code. and why are you taking so much flags variables...

code:

function datevalidate()
{
var val1=document.formname.fieldname.value;
var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
var year = currentTime.getFullYear()
var val2=document.write(month + "/" + day + "/" + year)
if(val1<val2)
{
alert("please start date should be greater than current date");
return false;
}
return true;
}

try this simple code... it's really fine.

regards, sanju...
