## Disable mouse scroll wheel zoom on embedded Google Maps
Question:

I work on a WordPress site where the authors usually embed Google Maps using iFrames in most posts.
Is there a way to disable the zoom via mouse scroll wheel on all of them using Javascript?


Solution:
I was having the same problem: when scrolling the page then the pointer becomes over the map,
it starts to zoom in/out the map instead of continuing scrolling the page. :(

So I solved this putting a div with an .overlay exactly before each gmap iframe insertion, see:
In my CSS i created the class:


The div will cover the map, preventing pointer events from getting to it. But if you click on the div,
it becomes transparent to pointer events, activating the map again!

I hope get helped you :)
