How to disable mouse scroll wheel scaling with Goo

Question

I am using Google Maps API (v3) to draw a few maps on a page. One thing I'd like to do is disable zooming when you scroll the mouse wheel over the map, but I'm unsure how.

I have disabled the scaleControl (i.e. removed the scaling UI element), but this doesn't prevent scroll wheel scaling.

Here is part of my function (it's a simple jQuery plugin):

$.fn.showMap = function(options, addr){
  options = $.extend({
    navigationControl: false,
    mapTypeControl: false,
    scaleControl: false,
    draggable: false,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }, options);
  var map = new google.maps.Map(document.getElementById($(this).attr('id')), options);

  // Code cut from this example as not relevant
};

Answer 1

Just in case, you are using the GMaps.js library, which makes it a bit simpler to do things like Geocoding and custom pins, here's how you solve this issue using the techniques learned from the previous answers.

var Gmap = new GMaps({
  div: '#main-map', // FYI, this setting property used to be 'el'. It didn't need the '#' in older versions
  lat: 51.044308,
  lng: -114.0630914,
  zoom: 15
});

// To access the Native Google Maps object use the .map property
if(Gmap.map) {
  // Disabling mouse wheel scroll zooming
  Gmap.map.setOptions({ scrollwheel: false });
}

Answer 2

You just need to add in map options:

scrollwheel: false

Answer 3

Use that piece of code, that will give you all the color and zooming control of google map. (scaleControl: false and scrollwheel: false will prevent the mousewheel from zoom up or down)

function initMap() {
            // Styles a map in night mode.
            var map = new google.maps.Map(document.getElementById('map'), {
                center: {lat: 23.684994, lng: 90.356331},
                zoom: 8,
                scaleControl: false,
                scrollwheel: false,
              styles: [
                {elementType: 'geometry', stylers: [{color: 'F1F2EC'}]},
                {elementType: 'labels.text.stroke', stylers: [{color: '877F74'}]},
                {elementType: 'labels.text.fill', stylers: [{color: '877F74'}]},
                {
                  featureType: 'administrative.locality',
                  elementType: 'labels.text.fill',
                  stylers: [{color: '#d59563'}]
                },
                {
                  featureType: 'poi',
                  elementType: 'labels.text.fill',
                  stylers: [{color: '#d59563'}]
                },
                {
                  featureType: 'poi.park',
                  elementType: 'geometry',
                  stylers: [{color: '#263c3f'}]
                },
                {
                  featureType: 'poi.park',

                  stylers: [{color: '#f77c2b'}]
                },
                {
                  featureType: 'road',
                  elementType: 'geometry',
                  stylers: [{color: 'F5DAA6'}]
                },
                {
                  featureType: 'road',
                  elementType: 'geometry.stroke',
                  stylers: [{color: '#212a37'}]
                },

                  featureType: 'road',
                  elementType: 'labels.text.fill',
                  stylers: [{color: '#f77c2b'}]
                },
                {
                  featureType: 'road.highway',
                  elementType: 'geometry',
                  stylers: [{color: '#746855'}]
                },
                {
                  featureType: 'road.highway',
                  elementType: 'geometry.stroke',
                  stylers: [{color: 'F5DAA6'}]
                },
                {
                  featureType: 'road.highway',
                  elementType: 'labels.text.fill',
                  stylers: [{color: 'F5DAA6'}]
                },
                {
                  featureType: 'transit',
                  elementType: 'geometry',
                  stylers: [{color: '#2f3948'}]
                },

                  stylers: [{color: '#f77c2b3'}]

             var marker = new google.maps.Marker({
              position: {lat: 23.684994, lng: 90.356331},
              map: map,
              title: 'BANGLADESH'
            });
          }

Answer 4

Just in case you want to do this dynamically;

function enableScrollwheel(map) {
    if(map) map.setOptions({ scrollwheel: true });
}

function disableScrollwheel(map) {
    if(map) map.setOptions({ scrollwheel: false });
}

Sometimes you have to show something "complex" over the map (or the map is a small part of the layout), and this scroll zooming gets in the middle, but once you have a clean map, this way of zooming is nice.

Answer 5

Just incase anybody is interested in a pure css solution for this. The following code overlays a transparent div over the map, and moves the transparent div behind the map when it is clicked. The overlay prevents zooming, once clicked, and behind the map, zooming is enabled.

See my blog post Google maps toggle zoom with css for an explanation how it works, and pen codepen.io/daveybrown/pen/yVryMr for a working demo.

Disclaimer: this is mainly for learning and probably won't be the best solution for production websites.

HTML:

<div class="map-wrap small-11 medium-8 small-centered columns">
    <input id="map-input" type="checkbox" />
    <label class="map-overlay" for="map-input" class="label" onclick=""></label>
    <iframe src="https://www.google.com/maps/embed?pb=!1m14!1m12!1m3!1d19867.208601651986!2d-0.17101002911118332!3d51.50585742500925!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!5e0!3m2!1sen!2suk!4v1482355389969"></iframe>
</div>

CSS:

.map-wrap {
    position: relative;
    overflow: hidden;
    height: 180px;
    margin-bottom: 10px;
}

#map-input {
    opacity: 0;
}

.map-overlay {
    display: block;
    content: '';
    position: absolute;
    top: 0;
    left: 0;
    width: 100% !important;
    height: 100% !important;
    overflow: hidden;
    z-index: 2;    
}

#map-input[type=checkbox]:checked ~ iframe {
    z-index: 3;
}

#map-input[type=checkbox]:checked ~ .map-overlay {
    position: fixed;
    top: 0;
    left: 0;
    width: 100% !important;
    height: 100% !important;
}


iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 100% !important;
    height: 100% !important;
    z-index: 1;
    border: none;
}

Answer 6

In version 3 of the Maps API you can simply set the scrollwheel option to false within the MapOptions properties:

options = $.extend({
    scrollwheel: false,
    navigationControl: false,
    mapTypeControl: false,
    scaleControl: false,
    draggable: false,
    mapTypeId: google.maps.MapTypeId.ROADMAP
}, options);

If you were using version 2 of the Maps API you would have had to use the disableScrollWheelZoom() API call as follows:

map.disableScrollWheelZoom();

The scrollwheel zooming is enabled by default in version 3 of the Maps API, but in version 2 it is disabled unless explicitly enabled with the enableScrollWheelZoom() API call.
