Modify POST vars before post, using jQuery

Question

I have a form, and a submit handler in jQuery.

When the user submits the form, I want to modify (add) some parameters to the POST request, before it is despatched fr

Answer 1

Attach a submit() handler to the form.

$('form#myForm').submit(myPostHandlingFunction);

Then submit/ do the post from your function. The easiest thing would be to just populate a couple of hidden inputs in the form and then return true to allow the submit to happen if everything looks right.
