I'm drawing multiple radius circles on my map with the following code:
function drawRadius(size){
var circle = new google.maps.Marker({
position: map.getCenter(),
zIndex: 1,
icon: {
path: google.maps.SymbolPath.CIRCLE,
scale: size,
strokeOpacity: 0.65,
strokeWeight: 4,
fillColor: '#FEFCF3',
fillOpacity: 0.08,
strokeColor: '#efe8b2'
},
map: map
});
}
This method is called multiple times with different size parameters, it results in the the following image:
Unfortunately, I can't move the map anymore, because - as far as I can tell - the events are now fired on the circles and not on the map.
How can I fix this? I just want to be able to normally drag/move the map.
Thank you!
If you don't need to click on the circles (markers), set clickable: false on them, that prevents the markers from receiving mouse events.
From the documentation:
clickable boolean If true, the marker receives mouse and touch events. Default value is true.
function drawRadius(size){
var circle = new google.maps.Marker({
position: map.getCenter(),
zIndex: 1,
clickable: false,
icon: {
path: google.maps.SymbolPath.CIRCLE,
scale: size,
strokeOpacity: 0.65,
strokeWeight: 4,
fillColor: '#FEFCF3',
fillOpacity: 0.08,
strokeColor: '#efe8b2'
},
map: map
});

Hi i have a problem with rotating a mark, roation works fine but it changes its position when its rotated, is there any way to fix this
const image = {
path: "M14 8.947L22 14v2l-8-2.526v5.36l3 1.666V22l-4.5-1L8 22v-1.5l3-1.667v-5.36L3 16v-2l8-5.053V3.5a1.5 1.5 0 0 1 3 0v5.447z",
fillColor: "#ffd400",
fillOpacity: 1,
strokeColor: "000",
strokeOpacity: 0.4,
scale: 1,
rotation: 0,
};
const aircraft = new google.maps.Marker({
position: { lat: 51.9189046, lng: 19.1343786 },
map,
icon: image,
});
The rotation for an SVG symbol is around the anchor position. The default anchor for an SVG Symbol is the upper left corner. To rotate the marker around the center, set the anchor to be the center of the image, which for your icon is:
anchor: new google.maps.Point(13, 13)
complete marker definition:
const image = {
path: "M14 8.947L22 14v2l-8-2.526v5.36l3 1.666V22l-4.5-1L8 22v-1.5l3-1.667v-5.36L3 16v-2l8-5.053V3.5a1.5 1.5 0 0 1 3 0v5.447z",

I have left you this example code in order to have a broader panorama of my problem, because precisely what I am trying to do is a type of home delivery and the areas in blue marked on the map are the areas in which If there is coverage of my home delivery, but if the marker is located outside of them, or if the client moves them outside of them, I need the alert to be displayed to warn that it cannot be, I appreciate all the support, greetings.
You can do this by getting the bounds getBounds() of the circle and check if the location of the marker is within those bounds like so:
function init() {
var
contentCenter = '<span class="infowin">Center Marker (draggable)</span>',
contentA = '<span class="infowin">Marker A (draggable)</span>',
contentB = '<span class="infowin">Marker B (draggable)</span>';
var
latLngCenter = new google.maps.LatLng(37.081476, -94.510574),
latLngCMarker = new google.maps.LatLng(37.0814, -94.5105),
latLngA = new google.maps.LatLng(37.2, -94.1),
latLngB = new google.maps.LatLng(38, -93),
map = new google.maps.Map(document.getElementById('map'), {
zoom: 7,
center: latLngCenter,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false
}),
markerCenter = new google.maps.Marker({
position: latLngCMarker,
title: 'Location',
map: map,
draggable: true
}),
infoCenter = new google.maps.InfoWindow({
content: contentCenter
}),
markerA = new google.maps.Marker({
position: latLngA,
title: 'Location',
map: map,
draggable: true
}),
infoA = new google.maps.InfoWindow({
content: contentA
}),
markerB = new google.maps.Marker({
position: latLngB,
title: 'Location',
map: map,
draggable: true
}),
infoB = new google.maps.InfoWindow({
content: contentB
})
// exemplary setup:
// Assumes that your map is signed to the var "map"
// Also assumes that your marker is named "marker"
,
circle = new google.maps.Circle({
map: map,
clickable: false,
// metres
radius: 100000,
fillColor: '#fff',
fillOpacity: .6,
strokeColor: '#313131',
strokeOpacity: .4,
strokeWeight: .8
});
// attach circle to marker
circle.bindTo('center', markerCenter, 'position');
var
// get the Bounds of the circle
bounds = circle.getBounds()
// Note spans
,
noteA = jQuery('.bool#a'),
noteB = jQuery('.bool#b');
noteA.text(bounds.contains(latLngA));
noteB.text(bounds.contains(latLngB));
// get some latLng object and Question if it's contained in the circle:
google.maps.event.addListener(markerCenter, 'dragend', function() {
latLngCenter = new google.maps.LatLng(markerCenter.position.lat(), markerCenter.position.lng());
bounds = circle.getBounds();
noteA.text(bounds.contains(latLngA));
noteB.text(bounds.contains(latLngB));
});
google.maps.event.addListener(markerA, 'dragend', function() {
latLngA = new google.maps.LatLng(markerA.position.lat(), markerA.position.lng());
noteA.text(bounds.contains(latLngA));
});
google.maps.event.addListener(markerB, 'dragend', function() {
latLngB = new google.maps.LatLng(markerB.position.lat(), markerB.position.lng());
noteB.text(bounds.contains(latLngB));
});
google.maps.event.addListener(markerCenter, 'click', function() {
infoCenter.open(map, markerCenter);
});
google.maps.event.addListener(markerA, 'click', function() {
infoA.open(map, markerA);
});
google.maps.event.addListener(markerB, 'click', function() {
infoB.open(map, markerB);
});
google.maps.event.addListener(markerCenter, 'drag', function() {
infoCenter.close();

I'm asking because I've searched everywhere online and this is all I have been able to find. So far I've been able to make dashed lines on google maps with the following code.
app.config.dashSymbol = {
path: 'M 0,-1 0,1',
strokeOpacity: 1,
scale: 4,
},
new google.maps.Polyline({
map:map,
path:polygon.getPath ? polygon.getPath() : polygon,
strokeColor: vue.Projects[projectID].ContractorColor,
strokeOpacity:0,
icons:[{
icon:app.config.dashSymbol,
offset:'0',
repeat:'20px'
}],
})
That all works fine, but is there a way that I can make a Polygon object with a dashed outline? I tried this, by it doesn't work
new google.maps.Polygon({
map:map,
paths:polygon.getPath ? polygon.getPath() : polygon,
fillColor: vue.Projects[projectID].ContractorColor,
strokeColor:vue.Projects[projectID].ContractorColor,
strokeOpacity:0,
icons:[{
icon:app.config.dashSymbol,
offset:'0',
repeat:'20px'
}]
})
I don't think you can. But you could overlay a Polyline on top of the Polygon.
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(40, 9),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var path = [
new google.maps.LatLng(39, 4),
new google.maps.LatLng(34, 20),
new google.maps.LatLng(44, 20),
new google.maps.LatLng(39, 4)
];
var lineSymbol = {
path: google.maps.SymbolPath.CIRCLE,
fillOpacity: 1,
scale: 2
};
var polygon = new google.maps.Polygon({
strokeOpacity: 0,
strokeWeight: 0,
fillColor: '#00FF00',
fillOpacity: .6,
paths: path,
map: map
});
var polylineDotted = new google.maps.Polyline({
strokeColor: '#000000',
strokeOpacity: 0,
icons: [{
icon: lineSymbol,
offset: '0',
repeat: '10px'
}],
path: path,
map: map
});
}
initialize();

I want to define the longitude latitude once. Right now it only works if it's defined twice.
I've moved things around but all I've managed is a broken map. The font icon only shows when long and lat are in there twice.
Here's my code:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(27.86336,-101.130738),
zoom: 16,
disableDefaultUI: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("google-map"), mapOptions);
new google.maps.Marker({
map: map,
icon: {
path: fontawesome.markers.EXCLAMATION,
scale: 0.5,
strokeWeight: 0,
strokeColor: 'transparent',
strokeOpacity: 0,
fillColor: 'red',
fillOpacity: 1,
},
clickable: false,
position: new google.maps.LatLng(27.86336,-101.130738)
});
}
google.maps.event.addDomListener(window, "load", initialize);
I've used the font marker solution from here: Using Icon Fonts as Markers in Google Maps V3 if that helps
You can merely do:
function initialize() {
var myLatLng = new google.maps.LatLng(27.86336. -101.130738);
var mapOptions = {
center: myLatLng,
zoom: 16,
disableDefaultUI: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("google-map"), mapOptions);
new google.maps.Marker({
map: map,
icon: {
path: fontawesome.markers.EXCLAMATION,
scale: 0.5,
strokeWeight: 0,
strokeColor: 'transparent',
strokeOpacity: 0,
fillColor: 'red',
fillOpacity: 1,
},
clickable: false,
position: myLatLng
});
}
google.maps.event.addDomListener(window, "load", initialize);
As long as you declare the variable within scope you shouldn't have any issues?
I have a map that will contain a group of colored polygons. There are times I want to change the fill color of each poly from whatever it is to transparent. I have the following code:
polys[x].setOptions({
fillColor: "#FFFFFF",
fillOpacity: .01, //This changes throughout the program
strokeColor: '#000000',
});
How can I set the fillColor to transparent? Is there a specific hex value?
The google.maps.PolygonOptions.fillColor is just that, a color, there is no "transparent" color, that is an Opacity value (0.0 is fully transparent, 1.0 if fully opaque).
fillColor | string | The fill color. All CSS3 colors are supported except for extended named colors.
fillOpacity | number | The fill opacity between 0.0 and 1.0
Update: 0.0 seems to work now for transparent Polygons (jsfiddle)
