Question

我想在google地图标记中添加一个svg图标。现在我可以通过单一路径创建一个svg图标，请找到以下代码：

    var car = "M17.402,0H5.643C2.526,0,0,3.467,0,6.584v34.804c0,3.116,2.526,5.644,5.643,5.644h11.759c3.116,0,5.644-2.527,5.644-5.644 V6.584C23.044,3.467,20.518,0,17.402,0z M22.057,14.188v11.665l-2.729,0.351v-4.806L22.057,14.188z M20.625,10.773 c-1.016,3.9-2.219,8.51-2.219,8.51H4.638l-2.222-8.51C2.417,10.773,11.3,7.755,20.625,10.773z M3.748,21.713v4.492l-2.73-0.349 V14.502L3.748,21.713z M1.018,37.938V27.579l2.73,0.343v8.196L1.018,37.938z M2.575,40.882l2.218-3.336h13.771l2.219,3.336H2.575z M19.328,35.805v-7.872l2.729-0.355v10.048L19.328,35.805z";
icon = {
    path: car
    , scale: 1
    , strokeColor: 'white'
    , strokeWeight: .10
    , fillOpacity: 1
    , fillColor: '#8dc63f'
    , offset: '100%', //rotation: parseInt(heading[0]),
    anchor: new google.maps.Point(10, 25)
};
marker.setIcon(icon);

我将图标传递给标记以在地图上显示图标。这是一条单一的道路。

现在我想使用svg路径创建一个带有多色的图标。那么任何人都可以发布如何创建多色svg路径图标并将其传递到谷歌地图标记。

根据this link，您可以使用包含SVG的data:image网址作为标记的图标。

var $markerImage = document.querySelector('.markerImage'),
  markerImageSvg = $markerImage.innerHTML || '';
var marker = new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    clickable: false,
    icon: {
      anchor: new google.maps.Point(16, 16),
      url: 'data:image/svg+xml;charset=utf-8,' + encodeURIComponent(markerImageSvg.replace('{{background}}', colors[0]))
    }
  });

代码段

function initialize() {
  var map = new google.maps.Map(
    document.getElementById("map_canvas"), {
      center: new google.maps.LatLng(37.4419, -122.1419),
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

  var $markerImage = document.querySelector('.markerImage'),
    markerImageSvg = $markerImage.innerHTML || '';
  new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    clickable: false,
    icon: {
      anchor: new google.maps.Point(16, 16),
      url: 'data:image/svg+xml;charset=utf-8,' + encodeURIComponent(markerImageSvg.replace('{{background}}', "#FF4847"))
    }
  });
}
google.maps.event.addDomListener(window, "load", initialize);
