Add event _vml correlation to VML

The close integration of VML and HTML makes it easy to add events to VML. All of the HTML events can be applied to the middle of the VML! The following example shows: When the mouse moves to the circle, the circle follows the mouse movement, when the mouse click, the circle stops moving.






I do not know if you have noticed that the event area of VML is strictly in its own shape, not as a picture, but as a rectangle. By the way, the function object is used, and if there is less content for the functions, and the call is made once, you can use a function object, by using new to create a function object, which is the contents of the functions. A good way to control events is to use a global variable, an event's execution depends on a global variable, and the other event can set the global variable so that events can be controlled.
