TypeScript

const parser = new DOMParser();
const mapElement = document.querySelector('gmp-map') as google.maps.MapElement;

async function initMap() {
    // Request needed libraries.
    const { Map } = await google.maps.importLibrary("maps") as google.maps.MapsLibrary;
    const { AdvancedMarkerElement, PinElement } = await google.maps.importLibrary("marker") as google.maps.MarkerLibrary;

    // Each PinElement is paired with a marker to demonstrate setting each parameter.

    // 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);

    // 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);

    // 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);

        position: { lat: 37.415, lng: -122.035 },
    });
    markerBorder.append(pinBorder);
    mapElement.append(markerBorder);

    // 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);

    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);

本页面介绍了如何通过以下方式自定义标记：

添加标题文字
缩放标记
更改背景颜色
更改边框颜色
更改字形颜色
在字形中使用文字
隐藏字形

高级标记使用两个类来定义标记：AdvancedMarkerElement 类提供基本参数（position、title 和 map），PinElement 类包含进一步自定义的选项。

如需向地图添加标记，您必须先加载 marker 库，该库提供 AdvancedMarkerElement 和 PinElement 类。

以下代码段展示了用于创建新 PinElement 并将其应用于标记的代码。

// 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);

在使用自定义 HTML 元素创建的地图中，标记的基本参数使用 gmp-advanced-marker HTML 元素声明；使用 PinElement 类的任何自定义设置都必须以程序化方式应用。为此，您的代码必须从 HTML 网页中检索 gmp-advanced-marker 元素。以下代码段显示了用于查询 gmp-advanced-marker 元素集合的代码，然后遍历结果以应用在 PinElement 中声明的自定义设置。

// 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);
}

添加标题文字

将光标悬停在标记上时会显示标题文字。标题文字可由屏幕阅读器读出。

如需以程序化方式添加标题文本，请使用 AdvancedMarkerElement.title 选项：

// 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);index.js

如需向使用自定义 HTML 元素创建的标记添加标题文本，请使用 title 属性：

<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>index.html

缩放标记

如需缩放标记，请使用 scale 选项。

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);index.ts

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);index.js

更改背景颜色

使用 PinElement.background 选项可更改标记的背景颜色：

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);index.ts

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);index.js

更改边框颜色

使用 PinElement.borderColor 选项可更改标记的边框颜色：

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);index.ts

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);index.js

更改字形颜色

使用 PinElement.glyphColor 选项可更改标记的字形颜色：

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);index.ts

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);index.js

使用字形中的文字

使用 PinElement.glyphText 选项可将默认字形替换为文本字符。PinElement 的文本字形会随 PinElement 进行缩放，其默认颜色与 PinElement 的默认 glyphColor 相匹配。

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);index.ts

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);index.js

隐藏字形

将 PinElement.glyphText 选项设置为空字符串可隐藏标记的字形：

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);index.ts

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);index.js

此外，还可以将 PinElement.glyphColor 设为与 PinElement.background 一样的值。此操作可实现隐藏字形的视觉效果。
