how can i add the EventListen on "wheel"

[leehonleon]

Because I am making a network application, loading a large number of DCM files will consume a lot of bandwidth, so I want to allocate the load of DCM files.

the same as #954 , but #954 do has sample code. First , how to add event listening for "wheel" ?

Not sure I get your question, but wheel is a browser event, check wheel_event on MDN.
