I've copied over code from an exciting website (https://romonysetra.no/tomtevelger/) to new website build (WP Divi). But I have no luck getting the code to work on the new site.https://romonysetra.no/divi/tomtevelger/
Any tips on what is wrong or what it not working on the new website build is greatly appreciated. Thanks!

I'm using Leaflet to make a cloropleth map over Europe. I would like to remove the map so that just the cloropleth layer is visible (background white).
I've tried to use different versions of map.removeLayer but I haven't been able to make a change without removing all layers.
I've also tried to alter .leaflet-container in the css.
Any ideas on how to remove the background map and keep the colored layer over the countries?

If i'm understanding the question correct, Using the example you added in the comments, I believe you can hide .leaflet-tile-container?

This is a mapbox.js / leaflet map, not mapbox-gl-js, so the difference is in Leaflet the scroll zoom control is called scrollWheelZoom not scrollZoom. If you replace the last line of your script with the following it should work. http://jsfiddle.net/x5j669zj/
if (map.scrollWheelZoom) {
map.scrollWheelZoom.disable();
}
I'm trying to create an online map using OpenLayers 3.
I'm brand new to using OpenLayers, and all I'm trying to do is to get the coordinates of the points, lines, polygons that I drew on the map. I'm aware that there is a featuresadded parameter available, but I'm not able to implement it correctly.
Can anybody point me in the right direction how to get the coordinates of a drawn feature (either in an alert() or console.log)?
Thanks a ton!!

Register a listener on ol.source.Vector and wait until the drawn feature is added:
source.on('addfeature', function(evt){
var feature = evt.feature;
var coords = feature.getGeometry().getCoordinates();
});
Use drawend event
drawend (ol.interaction.DrawEvent) - Triggered upon feature draw ends
Ex:
this.draw = new ol.interaction.Draw();
this.draw.on('drawend', function(evt){
//in evt you will get ol.feature
// from ol.feature get the geometry and than get coordinates
});
Let me know if I am wrong.
I have a script that was written a long time ago and not by me that I have updated from V2 to V3 and I am trying to draw range rings from a centered LatLng point. This worked in V2 but it is not working in V3 and I can't figure out why as I know some of the code is depreciated but not sure what it needs to be replaced with.
//Function to draw circles
function doDrawCircle(circleUnits, center, circleRadius, liColor, liWidth, liOpa, fillColor, fillOpa, opts, radials){
var bounds = new google.maps.LatLngBounds();
var circlePoints = Array();
with (Math) {
if (circleUnits == 'KM') {
var d = circleRadius/6378.8; // radians
}
else { //miles
var d = circleRadius/3963.189; // radians
}
var lat1 = (PI/180)* center.lat(); // radians
var lng1 = (PI/180)* center.lng(); // radians
for (var a = 0 ; a < 361 ; a++ ) {
var tc = (PI/180)*a;
var y = asin(sin(lat1)*cos(d)+cos(lat1)*sin(d)*cos(tc));
var dlng = atan2(sin(tc)*sin(d)*cos(lat1),cos(d)-sin(lat1)*sin(y));
var x = ((lng1-dlng+PI) % (2*PI)) - PI ; // MOD function
var point = new google.maps.LatLng(parseFloat(y*(180/PI)),parseFloat(x*(180/PI)));
circlePoints.push(point);
bounds.extend(point);
if(a==0){
var offset = new google.maps.Size(-5,0); // Added the offset - mile markers look a bit better
var label = new ELabel(point, circleRadius, "style1", offset, 40);
map.addOverlay(label);
}
if (((a==0) || (a==45) || (a==90) || (a==135) || (a==180) || (a==225) || (a==270) || (a==315)) && radials) {
//if (((a==0) || (a==45) || (a==90) || (a==135) || (a==180)) && radials) {
var pline = new google.maps.Polyline([center,point] , liColor, liWidth, liOpa);
map.addOverlay(pline);
}
}
var poly = new google.maps.Polygon(circlePoints, liColor, liWidth, liOpa, fillColor, fillOpa, opts);
map.addOverlay(poly); // Add a target circle to the map
map.setZoom(map.getBoundsZoomLevel(bounds)); // This sets the map bounds to be as big as the target circles, comment out if you don't want it
}
}
Then I have this within the initialize() function for the map.
// You can add circles, or change other parameters
// radials should be set to true for the maximum distance if you want radials
// doDrawCircle(circleUnits, center, circleRadius, lineColor, lineWidth, lineOpacity, fillColor, fillOpacity, opts, radials)
doDrawCircle('MI',llCenter, 62, lcolor, 1, .7, "#FFFF00", 0, { clickable: false }, false);
doDrawCircle('MI',llCenter, 124, lcolor, 1, .7, "#FFFF00", 0, { clickable: false }, false);
doDrawCircle('MI',llCenter, 187, lcolor, 1, .7, "#FFFF00", 0, { clickable: false }, false);
doDrawCircle('MI',llCenter, 249, lcolor, 1, .7, "#FFFF00", 0, { clickable: false }, false);
doDrawCircle('MI',llCenter, 312, lcolor, 1, .7, "#FFFF00", 0, { clickable: false }, false);
doDrawCircle('MI',llCenter, 374, lcolor, 1, .7, "#FFFF00", 0, { clickable: false }, false);
// doDrawCircle('MI',llCenter, 374, lcolor, 1, .7, '#00FF00', 0, { clickable: false }, true); // This would add the radials
This is what it is suppose to look like. This is from the working V2 map.

First thing you'll need to do is get the newest version of elabel.js for google maps V3 here:
https://github.com/erunyon/ELabel/blob/master/elabel.js
Then, the good news is you don't need all of that complicated math and stuff which you have going on in your doDrawCircle function. You can now make use of google.maps.Circle as well as the geometry library which must be included via the google maps script tag's url parameters using a 'libraries=geometry' parameter so we can get the text label placement position starting point via google.maps.geometry.spherical.computeOffset. And then I've included a little tweeking of the text placement below to look a bit more tidy.

EDIT:
Here is revised version which allows to toggle visibility of the rings via the 'Range' button. Also removed all the text label positioning adjustment math and replaced with using style classes for different length texts instead (makes it easier to just use em units in the styles if desired). Added LabelCircle constructor for easier encapsulation and simultaneous control of circles & labels.
