[jQuery] Field Highlight when comparing form fields

[jQuery] Field Highlight when comparing form fields


Hi,
I am trying to get a field highlighter working. I have a 2 column
layout with a form in each. The form on the left is the 'original'
data and the form on the right is newly updated. I would like to look
at each form field and compare their values and if different add a
class to highlight the change. I have the following code:

The forms are quite large and this code basically kills the browser
and I get a Slow script warning. Does anyone know if there is a way to
speed this up or make it more efficient or should I handle it server
side?
Cheers
Dave
