leaflet中地图交互事件(map interaction events)的触发顺序

地图交互事件(map interaction events)有以下类型：
"preclick", "click", "dblclick", "mouseover", "mousemove", "mousedown", "mouseup", "mouseout", "keypress", "contextmenu"

//dblclick触发过程，click后又触发了一次mousemove
mouseover->mousemove->mousedown->mouseup->preclick->click->mousemove
                    ->mousedown->mouseup->preclick->click->dblclick->mousemove->mouseout

//contextmenu触发过程，没有preclick
mouseover->mousemove->mousedown->mouseup->contextmenu->mousemove->mouseout

//keypress触发过程，map需要获取焦点(need to be focused)，点击map可获取焦点
