js 获得鼠标的坐标
event.clientX 设置或获取鼠标指针位置相对于窗口客户区域的 x 坐标，其中客户区域不包括窗口自身的控件和滚动条。
event.clientY 设置或获取鼠标指针位置相对于窗口客户区域的 y 坐标，其中客户区域不包括窗口自身的控件和滚动条。
event.offsetX 设置或获取鼠标指针位置相对于触发事件的对象的 x 坐标。
event.offsetY 设置或获取鼠标指针位置相对于触发事件的对象的 y 坐标。
event.screenX 设置或获取获取鼠标指针位置相对于用户屏幕的 x 坐标。
event.screenY 设置或获取鼠标指针位置相对于用户屏幕的 y 坐标。
一般用event.clientX 和event.clientY的比较多！
