triggerHandler vs. trigger in jQuery

Question

Out of curiosity -- what is the purpose of / use cases for jQuery\'s triggerHandler? As far as I can tell, the only \"real\" differences between trigger

Answer 1

For me the main difference is that 'triggerHandler' returns whatever was returned by the last handler, whereas 'trigger' returns the jQuery object.

So, for a handler such as:

  $( document ).on( 'testevent', function ()
  {
    return false;
  });

Using 'triggerHandler' you can do the following:

  if( $( document ).triggerHandler( 'testevent' ) === false )
  {
    return;
  }

So you would use 'triggerHandler' if you wanted to respond to the result returned from the handler.
