Touch action tests

Just now I published the latest touch action tests. There are no nasty surprises, although IE remains idiosyncratic.

The most common touch action is the single tap. When that action occurs, browsers fire off a whole slew of events, mostly in order to remain backward compatible with older sites that only use mouse events. Although there are quite a few deviations from the “standard” order of these events, they don’t matter much. The average script won’t break because the mouseover event fires before the touchstart event. Still, I documented all deviations. Who knows when this will come in handy?

I also studied the double tap, pinch-zoom, and scroll actions and found that browsers generally fire those events you would expect. The contextmenu event, which could serve as a useful proxy for a touchhold actions, is badly supported.

I also updated the mobile events page with the new information gleaned from these tests.

Enjoy.
