Mousedown 或 touchstart 被调用？

Question

There's one thing that disturbs me: suppose, I have a laptop with mouse and touch display. What event will be called when I touch some object in a browser on a screen? Mousedown or touchstart? And another situation: what event will be called when I use a tablet with usb-mouse and make mouse-click at the browser?

Hope you can give me the answer.

I've checked it and here are results:

• Android Chrome caused 'touchstart'
• Android FF caused 'touchstart'
• Android browser (4.0.*) caused 'touchstart' and then 'mousedown'
• Android Opera caused both of them
• Laptop with Windows 8 and FF and touch display caused 'mousedown' when using touch
• The same laptop with Chrome caused both of events

A bit fanny. You can check it by yourself: jsfiddle.net/z5cygsb4/2/
