Google maps are used almost everywhere to either implement an address of a business, club, store or anything else on a lot of pages on the internet. It’s a nice and convenient way to do it.

BUT… almost on all pages where this is done, when you scroll down using the mouse wheel, once the mouse ends up inside the Google map, the map starts zooming out instead of the page continuing to scroll down.

Here’s how to make a Google map not zoom in or out when you scroll down a page with the mouse wheel and only zoom, pan or do anything with the Google map as soon as you click inside the map. The following workflow also blocks zooming again once the mouse leaves the Google map area.

I got this from Stackoverflow, reproducing it here in case the zombie apocalypse breaks out and stackoverflow goes bun bun.

First you want to add the following style to your website or custom CSS script in your WordPress installation:

.scrolloff {
  pointer-events: none;
}

Then you want to add the following JavaScript to the page:

<script type="text/javascript">
    jQuery(document).ready(function($) {
    console.log("allLoaded");
        // you want to enable the pointer events only on click;
        jQuery('#map_canvas1').addClass('scrolloff'); // set the pointer events to none on doc ready
	console.log("scrolloffAddedA");
        jQuery('#canvas1').on('click', function () {
	    console.log("clickDetected");
            jQuery('#map_canvas1').removeClass('scrolloff'); // set the pointer events true on click
	    console.log("scrolloffRemoved");
        });
        // you want to disable pointer events when the mouse leave the canvas area;
        jQuery("#map_canvas1").mouseleave(function () {
	    console.log("mouseLeft");
            jQuery('#map_canvas1').addClass('scrolloff'); // set the pointer events to none when mouse leaves the map area
	    console.log("scrolloffAddedB");
        });
    });
</script>

Note that I have a whole lot of echo’s in the code which let’s you debug the code. You might want to consider switching that off for efficiency.

And finally that’s how you want to embed the map itself:

<section id="canvas1" class="map">
<iframe id="map_canvas1" src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d87147.27677140976!2d7.324830610654608!3d46.95476576996358!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x478e39c0d43a1b77%3A0xcb555ffe0457659a!2sBern!5e0!3m2!1sde!2sch!4v1462400079917" width="100%" height="485" frameborder="0" style="border:0" allowfullscreen></iframe>
</section>

Here is how this looks like in the end:
