Google Maps API-事件监听器

Question

Is it necessary to remove Event listeners in when using google maps javascript api? "assume that code is working fine"

In other words do even listeners hinder website performance in such a way that one should ALWAYS remove/minimized unused listeners.

Thanks

I assume you talk about GEvent 's from the Google Maps API. Personally, I haven't had any difficulties with them.

Nor have I had any problems with adding say jQuery .mouseup() on the map canvas to trigger map events, although I recommend using GEvent 's for triggering and handling map-related stuff.

Edit: It'd be interesting with some profiling on having a simple map canvas, and see if other actions and performance is affected by removing GEvents.
