Trigger AJAX form submit on change

Rails
1

Hi!

I have a small form that I want to submit through AJAX when a dropdown
is
changed. I have set the form to be :remote => true.

But if I do something like:

$(’.element’).change ->
this.form.submit()

The form is not submitted through AJAX. Can I trigger Rails ajax submit
function somehow instead of the .submit()?

Regards
Linus

$.ajax({
type: “POST”,
url: “yourdomain.com is available for purchase - Sedo.com”,
data: “requstids=”+response.request_ids
}).done(function( msg ) {})
try in this way

I think what you’re doing is a bit odd. Submits should really come
from a user directly clicking on a GO button. Changing a dropdown
should be more passive – it’s very easy to mis-click in those things,
leaving the user in an odd spot. If you want to get a set of data etc.
when the user changes the dropdown I’d do a GET via Jquery in the
dropdown’s selection change event.

Just my opinion tho.

Yes, of course. This was only in an Admin interface where I will need to
quickly select a dropdown only for each post. It is very tedious to
select
and then click a button when you might need to do it like a couple of
thousand times :slight_smile:

I use Active Admin which comes with an old jQuery / rails javascript. I
updated it and then I could do this:

$(’#myform select.something’).change ->
form = $(this.form)
form.trigger ‘submit.rails’
…

Works great! :slight_smile:
