Date validation with javascript

P

pete0085

I found some sample code through some online searches for date validation
with javascript. Not really sure what I'm doing, but I have two dates I want
to validate. Basically a "to date" and "from date". The problem I'm having
is the script only works one one of the dates and not both.

Can someone help me with this if I post the code I'm using in a separate post?

Nobody can help if you don't post the code. Better still, publish the
entire page and post a link -we will need to see how the code is being
called, as well as the javascript itself.

I think this is the code where my problem is but not sure how to fix it. I
have one text box called "date", the other is "date1".

I tried to make two separate scripts, but then it only validates the second
date.

function ValidateForm(){
var dt=document.frmSample.date
if (isDate(dt.value)==false){
dt.focus()
return false
}
return true

Change the function to:

function ValidateForm(){
var dt=document.frmSample.date;
var dt1=document.frmSample.date1;
if (isDate(dt.value)==false) {
dt.focus();
return false;
}
if (isDate(dt1.value)==false){
dt1.focus();
return false;
}
return true;
}
