如何在谷歌地图API中向AdvancedMarkerElement添加自定义属性

问题描述 投票：0回答：1

我正在将地图标记迁移到 

AdvancedMarkerElement
和 我想向 
AdvancedMarkerElement

添加自定义属性

像这样：

new AdvancedMarkerElement({
  map: this.map,
  position: data.position,
  dataWHD: data.data,
})

这会产生以下错误：

Unknown property 'dataWHD' of AdvancedMarkerElement

我该怎么做。

提前致谢..

您无法将自定义属性直接添加到 

AdvancedMarkerElement
。

相反，您可以通过 

AdvancedMarkerElement
content
属性传输自定义属性，以便您可以使用所需的任何数据构建自己的标记。

以下是来自官方文档的示例。

async function initMap() {
  // Request needed libraries.
  const { Map } = await google.maps.importLibrary("maps");
  const { AdvancedMarkerElement } = await google.maps.importLibrary("marker");
  const center = { lat: 37.43238031167444, lng: -122.16795397128632 };
  const map = new Map(document.getElementById("map"), {
    zoom: 11,
    center,
    mapId: "4504f8b37365c3d0",
  });

  for (const property of properties) {
    const AdvancedMarkerElement = new google.maps.marker.AdvancedMarkerElement({
      map,
      content: buildContent(property),
      position: property.position,
      title: property.description,
    });

    AdvancedMarkerElement.addListener("click", () => {
      toggleHighlight(AdvancedMarkerElement, property);
    });
  }
}

function toggleHighlight(markerView, property) {
  if (markerView.content.classList.contains("highlight")) {
    markerView.content.classList.remove("highlight");
    markerView.zIndex = null;
  } else {
    markerView.content.classList.add("highlight");
    markerView.zIndex = 1;
  }
}

function buildContent(property) {
  const content = document.createElement("div");

  content.classList.add("property");
  content.innerHTML = `
