[EDIT] After a lot of digging around, I found out that the problem was in how I integrated the CKEditor into my page. The simple and obvious way does work in this case, as laid out in the accepted answer.
Hi,
I need to change the values of a form, after the submit button has been pressed, but before the actual submission has taken place.
I've tried hooking into the submit event of the form, and changing the text field values there manually, but it looks like that doesn't actually change the values submitted.
Any ideas?
