In a form_tag, there is a list of 10 to 15 checkboxes:

<%= check_box_tag 'vehicles[]', car.id %>

How can I select-all (put a tick in every single) checkboxes by RJS? Thanks

EDIT: Sorry I didn't make my question clear. What I meant to ask is how to add a "Select/Un-select All" link in the same page to toggle the checkboxes.
