Advanced markers uses two classes to define markers: the
AdvancedMarkerElement
class provides the basic parameters (position
,
title
, and map
), and the PinElement
class contains options for further
customization. The following snippet shows code to create a new PinElement
,
then apply it to a marker.
// Create a pin element.
const pin = new PinElement({
scale: 1.5,
});
// Create a marker and apply the element.
const marker = new AdvancedMarkerElement({
map,
position: { lat: 37.419, lng: -122.02 },
content: pin.element,
});
In maps created using HTML, the basic parameters for a marker are declared using
the gmp-advanced-marker
HTML element; any customization that uses the
PinElement
class must be applied programmatically. To do this, your code must
retrieve the gmp-advanced-marker
elements from the HTML page. The following
snippet shows code to query for a collection of gmp-advanced-marker
elements,
then iterate through the results to apply customization that was declared in the
PinElement
.
// Return an array of markers.
const advancedMarkers = [...document.querySelectorAll('gmp-advanced-marker')];
// Loop through the markers
for (let i = 0; i < advancedMarkers.length; i++) {
const pin = new PinElement({
scale: 2.0,
});
marker.appendChild(pin.element);
}
This page shows you how to customize markers in the following ways:
- Add title text
- Scale the marker
- Change the background color
- Change the border color
- Change the glyph color
- Hide the glyph
Add title text
Title text appears when the cursor hovers over a marker. Title text is readable by screen readers.
To add title text programmatically, use the AdvancedMarkerElement.title
option:
// Default marker with title text (no PinElement). const markerViewWithText = new AdvancedMarkerElement({ map, position: { lat: 37.419, lng: -122.03 }, title: "Title text for the marker at lat: 37.419, lng: -122.03", });
To add title text to a marker created using HTML, use the title
attribute:
<gmp-map center="43.4142989,-124.2301242" zoom="4" map-id="DEMO_MAP_ID" style="height: 400px" > <gmp-advanced-marker position="37.4220656,-122.0840897" title="Mountain View, CA" ></gmp-advanced-marker> <gmp-advanced-marker position="47.648994,-122.3503845" title="Seattle, WA" ></gmp-advanced-marker> </gmp-map>
Scale the marker
To scale a marker, use the scale
option.
TypeScript
// Adjust the scale. const pinScaled = new PinElement({ scale: 1.5, }); const markerViewScaled = new AdvancedMarkerElement({ map, position: { lat: 37.419, lng: -122.02 }, content: pinScaled.element, });
JavaScript
// Adjust the scale. const pinScaled = new PinElement({ scale: 1.5, }); const markerViewScaled = new AdvancedMarkerElement({ map, position: { lat: 37.419, lng: -122.02 }, content: pinScaled.element, });
Change the background color
Use the PinElement.background
option to change the background color of a marker:
TypeScript
// Change the background color. const pinBackground = new PinElement({ background: '#FBBC04', }); const markerViewBackground = new AdvancedMarkerElement({ map, position: { lat: 37.419, lng: -122.01 }, content: pinBackground.element, });
JavaScript
// Change the background color. const pinBackground = new PinElement({ background: "#FBBC04", }); const markerViewBackground = new AdvancedMarkerElement({ map, position: { lat: 37.419, lng: -122.01 }, content: pinBackground.element, });
Change the border color
Use the PinElement.borderColor
option to change the border color of a
marker:
TypeScript
// Change the border color. const pinBorder = new PinElement({ borderColor: '#137333', }); const markerViewBorder = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.03 }, content: pinBorder.element, });
JavaScript
// Change the border color. const pinBorder = new PinElement({ borderColor: "#137333", }); const markerViewBorder = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.03 }, content: pinBorder.element, });
Change the glyph color
Use the PinElement.glyphColor
option to change the glyph color of a marker:
TypeScript
// Change the glyph color. const pinGlyph = new PinElement({ glyphColor: 'white', }); const markerViewGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.02 }, content: pinGlyph.element, });
JavaScript
// Change the glyph color. const pinGlyph = new PinElement({ glyphColor: "white", }); const markerViewGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.02 }, content: pinGlyph.element, });
Hide the glyph
Set the PinElement.glyph
option to an empty string to hide a marker's glyph:
TypeScript
// Hide the glyph. const pinNoGlyph = new PinElement({ glyph: '', }); const markerViewNoGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.01 }, content: pinNoGlyph.element, });
JavaScript
// Hide the glyph. const pinNoGlyph = new PinElement({ glyph: "", }); const markerViewNoGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.01 }, content: pinNoGlyph.element, });
Alternatively, set PinElement.glyphColor
to the same value as PinElement.background
.
This has the effect of visually hiding the glyph.
