Hi,
Am new to javascript, i have two fields
1. Start time ( hh:mm:ss Am/Pm )
2. End time (hh:mm:ss Am/Pm)
i want to validate it. Start time should be always greater than end time.
Eg: start time : 10:00:00 Am
end time : 09:00:00 Am
It should alert the user, invalid time.
Suggesst me what to do..
<html>
<script language="javascript">
function validate(dt1,dt2)
{
var jdt1=Date.parse('20 Aug 2000 '+dt1);
var jdt2=Date.parse('20 Aug 2000 '+dt2);
/* if(jdt1=='NaN')
{
alert('invalid start time');
return false;
}
if(jdt2=='NaN')
{
alert('invalid end time');
return false;
}*/
if (jdt1>jdt2)
{
alert('start is greater');
}
else
{
alert('start is less equal');
}
}
</script>
<body>
<div>
<form name=frm id=frm action=temp.php method="get" accept="text/csv">
<P> </P>
start <INPUT id=txt1 name=txt1 value='10:30:05 am'> <br>
end <INPUT id=txt2 name=txt2 value='10:40:05 am'>
<input type=button value=ok id=button2 name=button2 onclick ='validate(document.frm.txt1.value,document.frm.txt2.value)'>
</P>
</form></div>
<script language='javascript'>
</script>
<div id="txtHint">
</div>
<P></P>
</body>
</html>" Start time should be always greater than end time. "
Cool,
finish the task before you start it
no wonder the op cant find logic to complete their code
Hi almostbob, I overlooked that sentence but this code should work in either way you
want.
anandhikrishnan, here is final code
<html>
<script language="javascript">
function validate(dt1,dt2)
{
var jdt1=Date.parse('20 Aug 2000 '+dt1);
var jdt2=Date.parse('20 Aug 2000 '+dt2);
if(isNaN(jdt1))
{
alert('invalid start time');
return false;
}
if(isNaN(jdt2))
{
alert('invalid end time');
return false;
}
if (jdt1>jdt2)
{
alert('start is greater');
}
else
{
alert('start is less equal');
}
}
</script>
<body>
<div>
<form name=frm id=frm action=temp.php method="get" accept="text/csv">
<P> </P>
start <INPUT id=txt1 name=txt1 value='10:30:05 am'> <br>
end <INPUT id=txt2 name=txt2 value='10:40:05 am'>
<input type=button value=ok id=button2 name=button2 onclick ='validate(document.frm.txt1.value,document.frm.txt2.value)'>
</P>
</form></div>
