我有一个闪烁的 SVG 代码:http://jsfiddle.net/Muthukumaru/n4d80zLd/

我正在尝试将此 SVG 代码添加到 Google map 中的特定指针，以便该特定标记闪烁我是 Google map API 的新手，如何将 SVG 代码添加到 Google map 代码:

这是 Google map 的代码:

我已经通过了带有链接 png 图像的特定中心标记: https://maps.gstatic.com/intl/en_ALL/mapfiles/markers2/boost-marker-mapview.png

我想传递上面提供的 JSfiddle 中的 SVG 代码，而不是 png 图像链接:任何人都可以帮忙吗，

谢谢

最佳答案

您不能使用 SVG 元素作为标记图标。您可以做的是使用 google.maps.OverlayView 模仿 google.maps.Marker 的行为元素。

例如:

    map.Overlay= new google.maps.OverlayView();

    map.Overlay.center_ = new google.maps.LatLng(lat_center, long_center);
    map.Overlay.reddot_ =  '<div id="reddot" class="reddot" style="position:relative;"><svg class="marker" height="66" width="66"><circle cy="33" cx="33" class="mark" r="25"><set id="show" attributeName="visibility" attributeType="CSS" to="visible" begin="0s; hide.end" dur="1s" fill="freeze"/><set id="hide" attributeName="visibility" attributeType="CSS" to="hidden" begin="show.end" dur="1s" fill="freeze"/></circle><img src="http://www.google.com/intl/en_us/mapfiles/ms/micons/red-dot.png" class="locater"></svg></div>';

    map.Overlay.draw = function () {
        var pixelposition = this.getProjection().fromLatLngToDivPixel(this.center_);
        jQuery('#reddot').css({top:(pixelposition.y-50), left:(pixelposition.x-33)});

    };

    map.Overlay.onAdd=function() {
      var self=this;
      jQuery(self.getPanes().markerLayer).append(self.reddot_);
    };

    map.Overlay.setMap(map);

(我使用 jQuery 将 SVG 附加到标记层 Pane ，但您也可以使用原始 js 来做到这一点)
