Question

Ideally I can do $(document.body).on("tap", "#myElement", this.eventHandler);

But jQuery hasn’t done that yet.

I see so many libraries — https://github.com/bebraw/jswiki/wiki/Touch. There’s a long list on that page.

They all seem to use old fashioned event listening. Such as, $("#element").touchLibraryThingy(); $("#element").bind("tap"). Equivalent to addEventListener.

That’s great for an ID (Sorta), but when I have 50 list items that all have events on them, I don’t want someone on an old Android to have 50 event listeners. For performance reasons!

Does anyone know of a library that uses event delegation that is finished?

Answer 1

Better yet, now with jQuery Mobile custom builder, you can only select their mobile events and get the latest touch code, which has improvements over the example above.
