Rails 3 UJS - on hover, not on click

Question

For my show action, I show show.js.erb. This happens when I click the link_to link with the setting :remote => true. How can I set it up so that it works on hover?

Answer 1

Create a link with an attribute that will not run the Rails-UJS driver:

<%= link_to 'mouse over me!', '#', :'data-remote-on-hover' => true %>

and then hook your own event:

$('a[data-remote-on-hover]').hover(function() {
  // do something
})

Answer 2

HTML5 Custom Data Attributes FTW!
