rails and javascript, know if the user has confirmed a dialog

In my rails 3.2.17 application, i have a delete button:

<%= link_to 'Delete', destroy_item_path(@item), 
    method: :delete, 
    data: { confirm: "Do you confirm?"},
    id: "a_delete" 
%>

I need to perform some javascript code after the item has been deleted, or better: after the user has confirmed to delete the item.
Naively, i added an id to the anchor and I bound an click listener:

$("#a_delete").click(function() {
    //Has the user confirmed or canceled the operation?
} );

But how can i know what is the user choice? I've checked the https://github.com/rails/prototype-ujs but I didn't figure out how and even if this can be done.

Click event occurs before the user can cancel or confirm. You could use a form and capture the submit action, which will only happen after the user confirms, and will not happen at all if the user cancels the dialog.

Instead of having rails.js handle showing the dialog, You can show dialog yourself in your click handler and respond accordingly:

$('#a_delete').click(function(e) {
    if(confirm('Do you confirm?') {
        alert('going to delete!');
    } else {
        e.preventDefault();
        alert('not going to delete!');
    }
} );

This will allow you to do your processing before the delete request is sent to the server.

Easy way(after item will destroyed) it's a send request as JS, rails will render destroy.js.erb and you can add code here. Hard way (after confirm before destroy) it's a modify rails confirmation dialog http://lesseverything.com/blog/archives/2012/07/18/customizing-confirmation-dialog-in-rails/
