How to compare a database field and form field and highlight differences

[kate1232323]

Hi there,

I have been trying to find a coldfusion function that will help, I have tried comparing two strings but the results of -1 1 or 0 aren't very useful.

I need to compare a database field with a form field and highlight all the differences in the form field in red.

Thanks

Katie

This is a non-trivial process.  Rather than doing a compare, you really are wanting to do a diff.  CF doesn't do this out of the box, but you might want to have a sniff around on Google to see if anyone has implemented anything for CF.
