Dear All,

I am working on a web application www.ireps.gov.in which is running successfully on IE6 & IE7 without any issue and we want to run it on IE8 but there were some issues.

I want to know that following:

1. There will be any chance of javascript failure while accessing the pages with IE8?

2. Can anyone submit negative values intentionally where only postive integer value allowed using IE8?


Please help me ASAP

I'm not an expert at this but once I worked on a migration project where we had a requirement to support IE 7 (we were running on IE 6). We did find a lot of javascript runtime errors. So you have to run your application against IE 8 and look for potential failures and fix them accordingly. I've recently started to use jQuery and it looks much more portable to be run on any browsers without any hassle.

Yes there can be errors and you guys and gals are already behind since IE9 is out. Might want to pony up and make it work with all modern day browsers. If your code depends on browser dependent code, it might/will fail.

Anyone can get around browser validation. It should not matter what is sent from the client, the server should be checking it too.
