Question

i want to build a custom event with jQuery that is not set to a DOM element.

It says in the jQuery description, that:

jQuery.event.trigger('test');

is to trigger an Custom Event.

But how i can catch it ??

thx in advance

Answer 1

I suppose you’re asking about that custom event (at least it made no sense for me attempting to catch the trigger): it’s done with .bind:

$('some_selector').bind('test', function() { 
  console.log('Test was caught'); }
);

UPDATE: Actually no, you don’t need a selector – just an object to be a ‘host’ of event. You might use something like this:

// taken from the comments at the Doc page
var o = {length: 3};
$(o).bind( 'custom', function(){ console.log('hi') } );
$(o).trigger('custom');

// Output
hi
hi
hi
