I would like to understand how jQuery event namespacing works across different browsers.

I don't see anything about this on MDN and I would like to know how to namespace events without using jQuery as well (on older IE as well on modern browsers)

Update (Oct 1st, 2017):

If anyone is interested, I've answered in another question how to write minimal events emitter with namespaces in Vanilla JavaScript: https://stackoverflow.com/a/44432013/104380

jQuery event namespaces are exactly that – jQuery event namespaces.

This feature is unique to jQuery; the DOM doesn't have anything like it.

The point of event namespaces is the ability to remove your event handlers by name only; the DOM APIs don't do that at all.

  • I know what they are and what they do, i want to know how they work so I could write my own code which does the same, without jQuery (so events won't collide) – vsync Feb 26 '13 at 17:49

    @vsync: Read the jQuery source. You can maintain an object of event handlers for each namespace and loop over them when raising events. – SLaks Feb 26 '13 at 18:06
