Question

I have a jQuery.ajax() POST request, that runs on button click and has its data parameter set to $(this).parents('form').serialize().

There is one Textarea in the form that has a default placeholder, which I would like to replace with a blank value just before the AJAX request is sent. Is it possible to achieve this using the beforeSend event of jQuery.ajax?

You could simply manipulate the form data.

$.extend($(this).parents('form').serialize(), { textarea_name: "" });

If you don’t want the value being sent at all, delete the property from the object returned by serialize().
