Pass extra variable when submitting a form using jQuery

Question

I have a form in which the Submit button does not sit within the

tags. The submit button has an click handler to submit the form via jQuer

Answer 1

This seems to be an old question, but since I just ran into a similar issue and found a good solution (for me), I thought I'd post it:

 $('#admin_form').trigger('submit', [ { 'variable_name': true } ]);

or

$('#admin_form').trigger('submit', [ 'variable_name', 'true' ]);

depending on whether you want to pass a variable called variable_name with value true or you want to pass 2 separate variables.

And just to be clear, this will not of course automatically submit variable_name with the rest of the form fields, but if you have a submit handler, as I do in jQuery, the variables will be passed as arguments, after the event.
