UIEvent.detail read-only property, when non-zero, provides the current (or next, depending on the event) click count.

For click or dblclick events, UIEvent.detail is the current click count.

For mousedown or mouseup events, UIEvent.detail is 1 plus the current click count.

对于所有其它 UIEvent 对象， UIEvent.detail is always zero.
