Hi all
I'm a complete newbie to web development and Javascript especially. I've been creating a form for a webpage and have used a validation script gen_validatorv2 .js which I downloaded from the zip file referenced on http://www.javascript-coder.com/html...lidation.phtml
I managed to get everything working and was testing through Firefox that alerts were generated. However at the very end I thought I'd better check it was all ok on IE and found that the alerts aren't being generated at all.
The scenario is that I have a form with several fields to complete and I tested it by leaving some of the mandatory ones blank. When I click on submit, the alerts pop up in Firefox and prevent the form being submitted. In IE, I don't get any alerts popping up and the form doesn't submit either.
As I'm completely new, I really don't know where to start on this and my web searches haven't yet come up with anything. I am happy to post code to this thread, but am not sure where to start. If you experts are able to advise, I would be very grateful :) Are there any well known differences between how IE and Firefox handle Javascript?
Many thanks

hi can u please post the code.
Thanks for the reply :)
The webpage is quite long so I'll try and post the relevant bits
1. This is within the <head> </head> section
<script src="gen_valida torv2.js" type="text/javascript"></script>
2. To start the form I have
<form name="myform" method="post" action="Contact _Us_with_java_p 2.php" />
3. This performs the validation and comes just after the end of </form>
<script type="text/javascript">
var frmvalidator = new Validator("myfo rm");
frmvalidator.ad dValidation("Re asonForSale","r eq","Please select your Reason For Sale");
frmvalidator.ad dValidation("Wo uldLikeToSellAn dRentBack","req ","Please select if you would like to Sell and Rent Back");
frmvalidator.ad dValidation("Wa ntToSellWithin" ,"req","Plea se select How Quickly You Need to Sell");
frmvalidator.ad dValidation("Fi rstName","req", "Please enter your First Name");
frmvalidator.ad dValidation("La stName","req"," Please enter your Last Name");
frmvalidator.ad dValidation("Em ail","email","P lease enter a valid email address");
frmvalidator.se tAddnlValidatio nFunction("Chec kContactNumber" );
</script>
4. Below is the first part of the gen_validatorv2 .js code ( I need to post the 2nd part in another post as it is too long)

Hi,
I have a problem with our intranet, we are planning to install Firefox
instead of Internet Explorer onto some new PCs.
However, we can't get the following JavaScript to work in Firefox and
similar code is used in lots of the intranet stuff.
The code should bring up a message box with a warning and not allow
the user to continue unless they have filled in the entry in an html
form (the form is called 'myauthor').

Hello Guys,
I am posting my weird experience on firefox by a piece of code I have
written. That piece of code is supposed to be executed when the page is not
posted back i.e., for the very first time.
In IE, my code is doing what it is supposed to do i.e.., it is not executing
that piece of code whenever page is posted back but in firefox browser it is
executing even if it is a postback.
