My JavaScript was working and now it's not.

It's just to validate the form

I started applying my template on the application and it seems at some point it just stopped...any ideas what could have done this?

  • 4 With problems like these, the best place to start is 'what changed?' – Amy Anuszewski Commented May 23, 2011 at 14:28
  • Pretty much adding the template. to me it seems onSubmit no longer works in the form function...not sure what that would mean however. – Josip Gòdly Zirdum Commented May 23, 2011 at 14:29
  • It's probably going to be something to do with adding a Doctype that triggers standards mode means that an error you made isn't being let through … but tracking through that entire script is going to be a tedious job. What error message do you get in your JS debugger? – Quentin Commented May 23, 2011 at 14:29
  • 4 please define 'stopped working' - does it error out? if so, what does a JavaScript console tool, such as those found in Chrome or FireFox w/ Firebug say? – Matt Commented May 23, 2011 at 14:30
  • @Matt: the JavaScript console is natively available in Firefox, you don't have to use Firebug for that (though it's a very valuable tool). – Marcel Korpel Commented May 23, 2011 at 14:32

Reset to default 6

Your JS is looking for Description but your form control is named description.

(There may be other errors, but that is the one that is currently causing the JS to bug out and not return false)

Error: document.forms.register.Description is undefined

You are calling it here - with capital D:

var Description=document.forms["register"]["Description"].value;

Change it to 

var Description=document.forms["register"]["description"].value;

I will give you one advice,

your javascript looks ok but you should use if you are not, Firefox extension called firebug, turn it on for your page and it will show you errors if you have any and will help you with web development.

You can get it http://getfirebug./

and also add return true; at the end of your methods
