Changing onkeypress behavior for field element

[Rick Measham]

I can't find this anywhere, so I hope it can be done:
Here's what I can do so far:

1. Certain fields have a class 'textfield' while others are
'textfieldreq'.

2. OnSubmit checks all elements and makes sure that those with 'req'
have some value

3. It then sets the border on empty required fields to red

Now what I want to do is:

4. alter the onkeypress for the field

5. to restore the original class when someone enters something.

Can this be done?

Cheers!
Rick

Use onchange instead. It is probably what you want.

You didn't say that you changed the class, only the border style.

Maybe something like this, in the code that recognizes empty fields:
---
badElement.style.border = "2px solid red"; // or whatever you do
badElement.onchange = function() { this.style.border="";
this.onchange=undefined; };
---
If you insist on using "onkeypress", change "onchange" to it
