javascript - Google 在 icon-fillColor 和 strokeColor 之间映射标记图标填充

Question

我正在尝试在 icon-fillColor 和外部 StrokeColor 之间创建一个带有填充的 Google 地图标记图标。

我的标记代码：

marker = new google.maps.Marker({
id: i,
position: position,
label: {
    text: 'id',
    color: "white",
    fontWeight: 'bold',
    fontSize: '16px',
},
map: map,
title: "My Title",
icon: {
    path: google.maps.SymbolPath.CIRCLE,
    scale: 15,
    fillColor: "#4A86FE",
    fillOpacity: 1.0,
    strokeWeight: 6,
    strokeOpacity: 0.8,
    strokeColor:"red",
    rotation: 30
},
animation: google.maps.Animation.DROP,});

我当前的输出：如果你能看到内蓝色圆圈和外红色圆圈相互接触。我正在尝试在内部和外部之间编码白色。检查我的预期输出。

我想要达到的目标如下：

像这样（使用两个重叠标记）应该可以工作，您可以添加其他参数（或创建“选项”对象）来定义各个部分的颜色：

function makeComplexIcon(map, latLng, fillColor, stripeColor, outsideColor, title, id, label) {
  var bottom = new google.maps.Marker({
    zIndex: 10, // bottom
    id: id,
    position: latLng,
    map: map,
    title: title,
    icon: {
      path: google.maps.SymbolPath.CIRCLE,
      scale: 15,
      fillColor: fillColor,
      fillOpacity: 1.0,
      strokeWeight: 6,
      strokeOpacity: 0.8,
      strokeColor: outsideColor,
      rotation: 30
    },
  });
  var top = new google.maps.Marker({
    zIndex: 15, // top
    id: id,
    position: latLng,
    label: label,
    map: map,
    title: title,
    icon: {
      path: google.maps.SymbolPath.CIRCLE,
      scale: 15,
      fillColor: fillColor,
      fillOpacity: 1.0,
      strokeWeight: 2,
      strokeOpacity: 0.8,
      strokeColor: stripeColor,
      rotation: 30
    },
  });

代码片段：

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {
      lat: -25.363882,
      lng: 131.044922
    }
  });

  var position = map.getCenter(),
    i = 10;
  makeComplexIcon(map, position, "#4A86FE", "white", "red", "My Title", i, {
    text: 'id',
    color: "white",
    fontWeight: 'bold',
    fontSize: '16px',
  });
  makeComplexIcon(map, {
    lat: -27.6728168,
    lng: 121.6283098
  }, "green", "yellow", "orange", "W. Australia", 12, {
    text: 'id1',
    color: "blue",
    fontWeight: 'bold',
    fontSize: '16px',
  })
  makeComplexIcon(map, {
    lat: -30.0,
    lng: 136.2
  }, "black", "white", "black", "S. Australia", 14, {
    text: 'id2',
    color: "red",
    fontWeight: 'bold',
    fontSize: '16px',
  })
}

function makeComplexIcon(map, latLng, fillColor, stripeColor, outsideColor, title, id, label) {
  var marker = new google.maps.Marker({
    zIndex: 10, // bottom
    id: id,
    position: latLng,
    map: map,
    title: title,
    icon: {
      path: google.maps.SymbolPath.CIRCLE,
      scale: 15,
      fillColor: fillColor,
      fillOpacity: 1.0,
      strokeWeight: 6,
      strokeOpacity: 0.8,
      strokeColor: outsideColor,
      rotation: 30
    },
  });
  var marker = new google.maps.Marker({
    zIndex: 15, // top
    id: id,
    position: latLng,
    label: label,
    map: map,
    title: title,
    icon: {
      path: google.maps.SymbolPath.CIRCLE,
      scale: 15,
      fillColor: fillColor,
      fillOpacity: 1.0,
      strokeWeight: 2,
      strokeOpacity: 0.8,
      strokeColor: stripeColor,
      rotation: 30
    },
  });
}
