Halaman ini menunjukkan cara menyesuaikan penanda dengan cara berikut:
- Menambahkan teks judul
- Menskalakan penanda
- Mengubah warna latar belakang
- Mengubah warna batas
- Mengubah warna glyph
- Menggunakan teks dalam glyph
- Menyembunyikan glyph
Penanda lanjutan menggunakan dua class untuk menentukan penanda: class AdvancedMarkerElement menyediakan parameter dasar (position,
title, dan map), dan class PinElement berisi opsi untuk penyesuaian lebih lanjut.
Untuk menambahkan penanda ke peta, Anda harus
memuat library marker terlebih dahulu
yang menyediakan class AdvancedMarkerElement
dan PinElement.
Cuplikan berikut menunjukkan kode untuk membuat PinElement baru, lalu menerapkannya ke
penanda.
// Create a pin element.
const myPin = new PinElement({
scale: 1.5,
});
// Create a marker.
const myMarker = new AdvancedMarkerElement({
position: { lat: 37.4239163, lng: -122.0947209 },
});
// Append the pin to the marker.
myMarker.append(myPin);
// Append the marker to the map.
mapElement.append(myMarker);
Dalam peta yang dibuat menggunakan elemen HTML kustom, parameter dasar untuk
penanda dideklarasikan menggunakan elemen HTML gmp-advanced-marker; penyesuaian
apa pun yang menggunakan class PinElement harus diterapkan
secara terprogram. Untuk melakukannya, kode Anda harus mengambil elemen gmp-advanced-marker
dari halaman HTML. Cuplikan berikut menunjukkan kode untuk membuat kueri
kumpulan elemen gmp-advanced-marker, lalu melakukan iterasi pada hasilnya
untuk menerapkan penyesuaian yang dideklarasikan di 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.append(pin);
}
Menambahkan teks judul
Teks judul muncul saat kursor diarahkan ke penanda. Teks judul dapat dibaca oleh pembaca layar.
Untuk menambahkan teks judul secara terprogram, gunakan opsi AdvancedMarkerElement.title:
// Default marker with title text (no PinElement). const markerWithText = new AdvancedMarkerElement({ position: { lat: 37.419, lng: -122.03 }, title: 'Title text for the marker at lat: 37.419, lng: -122.03', }); mapElement.append(markerWithText);
Untuk menambahkan teks judul ke penanda yang dibuat menggunakan elemen HTML kustom, gunakan atribut 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>Menskalakan penanda
Untuk menskalakan penanda, gunakan opsi scale.
TypeScript
// Adjust the scale. const pinScaled = new PinElement({ scale: 1.5, }); const markerScaled = new AdvancedMarkerElement({ position: { lat: 37.419, lng: -122.02 }, }); markerScaled.append(pinScaled); mapElement.append(markerScaled);
JavaScript
// Adjust the scale. const pinScaled = new PinElement({ scale: 1.5, }); const markerScaled = new AdvancedMarkerElement({ position: { lat: 37.419, lng: -122.02 }, }); markerScaled.append(pinScaled); mapElement.append(markerScaled);
Mengubah warna latar belakang
Gunakan opsi PinElement.background untuk mengubah warna latar belakang penanda:
TypeScript
// Change the background color. const pinBackground = new PinElement({ background: '#FBBC04', }); const markerBackground = new AdvancedMarkerElement({ position: { lat: 37.419, lng: -122.01 }, }); markerBackground.append(pinBackground); mapElement.append(markerBackground);
JavaScript
// Change the background color. const pinBackground = new PinElement({ background: '#FBBC04', }); const markerBackground = new AdvancedMarkerElement({ position: { lat: 37.419, lng: -122.01 }, }); markerBackground.append(pinBackground); mapElement.append(markerBackground);
Mengubah warna batas
Gunakan opsi PinElement.borderColor untuk mengubah warna batas penanda:
TypeScript
// Change the border color. const pinBorder = new PinElement({ borderColor: '#137333', }); const markerBorder = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.035 }, }); markerBorder.append(pinBorder); mapElement.append(markerBorder);
JavaScript
// Change the border color. const pinBorder = new PinElement({ borderColor: '#137333', }); const markerBorder = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.035 }, }); markerBorder.append(pinBorder); mapElement.append(markerBorder);
Mengubah warna glyph
Gunakan opsi PinElement.glyphColor untuk mengubah warna glyph penanda:
TypeScript
// Change the glyph color. const pinGlyph = new PinElement({ glyphColor: 'white', }); const markerGlyph = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.025 }, }); markerGlyph.append(pinGlyph); mapElement.append(markerGlyph);
JavaScript
// Change the glyph color. const pinGlyph = new PinElement({ glyphColor: 'white', }); const markerGlyph = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.025 }, }); markerGlyph.append(pinGlyph); mapElement.append(markerGlyph);
Menggunakan teks dalam glyph
Gunakan opsi PinElement.glyphText untuk mengganti glyph default dengan karakter
teks. Glyph teks PinElement diskalakan dengan PinElement dan
warna defaultnya cocok dengan glyphColor default PinElement.
TypeScript
const pinTextGlyph = new PinElement({ //@ts-ignore glyphText: 'T', glyphColor: 'white', }); const markerGlyphText = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.015 }, }); markerGlyphText.append(pinTextGlyph); mapElement.append(markerGlyphText);
JavaScript
const pinTextGlyph = new PinElement({ //@ts-ignore glyphText: 'T', glyphColor: 'white', }); const markerGlyphText = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.015 }, }); markerGlyphText.append(pinTextGlyph); mapElement.append(markerGlyphText);
Menyembunyikan glyph
Tetapkan opsi PinElement.glyphText ke string kosong untuk menyembunyikan glyph
penanda:
TypeScript
// Hide the glyph. const pinNoGlyph = new PinElement({ //@ts-ignore glyphText: '', }); const markerNoGlyph = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.005 }, }); markerNoGlyph.append(pinNoGlyph); mapElement.append(markerNoGlyph);
JavaScript
// Hide the glyph. const pinNoGlyph = new PinElement({ //@ts-ignore glyphText: '', }); const markerNoGlyph = new AdvancedMarkerElement({ position: { lat: 37.415, lng: -122.005 }, }); markerNoGlyph.append(pinNoGlyph); mapElement.append(markerNoGlyph);
Atau, tetapkan PinElement.glyphColor ke nilai yang sama dengan
PinElement.background. Tindakan ini memiliki efek menyembunyikan glyph secara visual.
