Testar amostra
Os Marcadores Avançados usam duas classes para definir marcadores: a
classe AdvancedMarkerElement
fornece os parâmetros básicos (position
,
title
e map
), e a classe PinElement
contém opções para mais
personalização.
Para adicionar marcadores a um mapa, primeiro carregue a biblioteca marker
, que fornece as classes AdvancedMarkerElement
e PinElement
.
O snippet a seguir mostra o código para criar um novo PinElement
e aplicá-lo a um marcador.
// 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,
});
Em mapas criados usando HTML, os parâmetros básicos de um marcador são declarados usando o elemento HTML gmp-advanced-marker
. Qualquer personalização que use a classe PinElement
precisa ser aplicada de forma programática. Para fazer isso, o código precisa
extrair os elementos gmp-advanced-marker
da página HTML. O snippet
abaixo mostra o código para consultar uma coleção de elementos gmp-advanced-marker
e iterar pelos resultados para aplicar a personalização declarada no
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);
}
Nesta página, mostramos como personalizar marcadores da seguinte forma:
- Adicionar texto do título
- Ajustar a escala do marcador
- Mudar a cor do plano de fundo
- Mudar a cor da borda
- Mudar a cor do glifo
- Usar texto em um glifo
- Ocultar o glifo
Adicionar texto do título
O texto do título aparece ao passar o cursor sobre um marcador e pode ser lido por leitores de tela.
Para adicionar o texto do título de forma programática, use a opção
AdvancedMarkerElement.title
:
// 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", });
Para adicionar o texto do título a um marcador criado usando HTML, use o atributo title
:
<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>
Ajustar a escala do marcador
Para redimensionar um marcador, use a opção scale
.
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, });
Mudar a cor do plano de fundo
Use a opção PinElement.background
para mudar a cor de fundo de um marcador:
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, });
Mudar a cor da borda
Use a opção PinElement.borderColor
para mudar a cor da borda de um marcador:
TypeScript
// Change the border color. const pinBorder = new PinElement({ borderColor: '#137333', }); const markerViewBorder = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.035 }, content: pinBorder.element, });
JavaScript
// Change the border color. const pinBorder = new PinElement({ borderColor: "#137333", }); const markerViewBorder = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.035 }, content: pinBorder.element, });
Mudar a cor do glifo
Use a opção PinElement.glyphColor
para mudar a cor do glifo de um marcador:
TypeScript
// Change the glyph color. const pinGlyph = new PinElement({ glyphColor: 'white', }); const markerViewGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.025 }, content: pinGlyph.element, });
JavaScript
// Change the glyph color. const pinGlyph = new PinElement({ glyphColor: "white", }); const markerViewGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.025 }, content: pinGlyph.element, });
Adicionar texto a um glifo
Use a opção PinElement.glyph
para substituir o glifo padrão por um caractere de texto. O glifo de texto de PinElement
é dimensionado com a PinElement
e
a cor padrão corresponde à glyphColor
padrão da PinElement
.
TypeScript
const pinTextGlyph = new PinElement({ glyph: 'T', glyphColor: 'white', }); const markerViewGlyphText = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.015 }, content: pinTextGlyph.element, });
JavaScript
const pinTextGlyph = new PinElement({ glyph: "T", glyphColor: "white", }); const markerViewGlyphText = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.015 }, content: pinTextGlyph.element, });
Ocultar o glifo
Defina a opção PinElement.glyph
como uma string vazia para ocultar o glifo de um marcador:
TypeScript
// Hide the glyph. const pinNoGlyph = new PinElement({ glyph: '', }); const markerViewNoGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.005 }, content: pinNoGlyph.element, });
JavaScript
// Hide the glyph. const pinNoGlyph = new PinElement({ glyph: "", }); const markerViewNoGlyph = new AdvancedMarkerElement({ map, position: { lat: 37.415, lng: -122.005 }, content: pinNoGlyph.element, });
Também é possível definir PinElement.glyphColor
como o mesmo valor que PinElement.background
.
O efeito é semelhante a ocultar o glifo.
