Autosubmit a form via AJAX (Rails 3.1)

Hi!

I have a form with only a checkbox. When the user clicks this checkbox I want to submit the form through AJAX. It’s like a TODO-list where you can mark the item as done by ticking a box.

So, how can I do this? :slight_smile: I’m using Rails 3.1.

I guess there is no native function to achieve this. So far I have this:

My form in the view:

 <%= form_for [@list, item], :remote => true do |f| %>
<%= f.check_box :status %>
 <% end %>

Then in my javascript file I guess I need to do something like (coffee):

$(‘input#item_status’).live ‘click’, (e) →

form = $(this).parent(‘form’)

/* SUBMIT FORM HERE! */

Any ideas?

Hi,

just run submit()

$('input#item_status').live 'click', ->    $(this).parent('form').submit()

param (e) is not needed, even in coffee :slight_smile:

Hehe great! I actually tried it in an onClick=“” but that didn’t submit the form through AJAX so I didn’t think it would work when doing it directly in jQuery either :slight_smile: It does work indeed.

And I now I don’t need the param (e). It’s a habit to pass in case I need it. Otherwise I remove it :slight_smile:

Thanks for the quick help!
