JQuery ajax: before event

Question

I saw some colleagues use this on rails

    $('[data-once=true]').live('ajax:before', function(request, e) {

});

However, I am trying to use it with jquery and it does not work, does this event come with a rails jquery adapter?

Answer 1

Yes, ajax:beforea jQuery event that adds / rails triggers, although this is not the latest version ajax:beforeSend. In jQuery, though ( ajax:beforewas around before the JS agnostic changes were tied to rails), you can just connect to it globally using a ajaxSendglobal event , like this:

$(document).bind('ajaxSend', function(e, request, options) {
  $('[data-once=true]').something();
});
