Conflict with Prototype.js when triggering a custom event called `update`

Reported by: christiedom@… Owned by:
Priority: undecided Milestone: None
Component: unfiled Version: 1.11.0

Blocked by: Blocking:


Triggering a custom event called update inside a keyup/keydown event handler prevents default behaviour when Prototype.js is included. No exceptions are thrown, but keystrokes in a textarea (which trigger update) have no effect.

keyup test case: http://jsbin.com/finix/14/edit

This bug has been reproduced with jQuery versions:

  • 1.8.3
  • 1.9.1
  • 1.10.2
  • 1.11.0

with Prototype.js versions:

  • 1.7.1

using the following Browsers:

  • IE8 Win XP
  • IE8 Win 7
  • IE9 Win 7
  • IE10 Win 7
  • IE11 Win 7

Works as expected on recent versions of Chrome OS X (32.0.1700.102), Firefox OS X (27), and on IE6 and IE7 on Windows XP.

This is because Prototype adds an .update() method to the element.


Augmenting an object you don't own with non-standard methods is bad practice and the source of several problems with Prototype.

As jQuery documents, when an event is fired on an element jQuery calls the corresponding DOM method if found. If you don't want that to happen, use .triggerHandler() rather than .trigger().
