Google Maps API和自定義標記

Question

我正在使用google maps api並想要創建一些自定義標記，除了顏色之外，它們都是一樣的，我不想重復這樣的代碼

 // Add a custom marker
var marker1 = {
    path: 'M12 2C8.13 2 5 5.13 5 9c0 5.25 7 13 7 13s7-7.75 7-13c0-3.87-3.13-7-7-7zm0 9.5c-1.38 0-2.5-1.12-2.5-2.5s1.12-2.5 2.5-2.5 2.5 1.12 2.5 2.5-1.12 2.5-2.5 2.5z',
    fillColor: '#ff61b4',
    fillOpacity: 0.95,
    scale: 2,
    strokeColor: '#fff',
    strokeWeight: 3,
    anchor: new google.maps.Point(12, 24)
};

var marker2 = {
    path: 'M12 2C8.13 2 5 5.13 5 9c0 5.25 7 13 7 13s7-7.75 7-13c0-3.87-3.13-7-7-7zm0 9.5c-1.38 0-2.5-1.12-2.5-2.5s1.12-2.5 2.5-2.5 2.5 1.12 2.5 2.5-1.12 2.5-2.5 2.5z',
    fillColor: '#05950a',
    fillOpacity: 0.95,
    scale: 2,
    strokeColor: '#fff',
    strokeWeight: 3,
    anchor: new google.maps.Point(12, 24)
};

當我想使用標記

 // Markers
var marker = new google.maps.Marker({
    map: map,
    icon: marker, // can i override the fillColor here ?
    position: new google.maps.LatLng(51.489401, -3.203586),
    title: 'title'
});

我希望能夠聲明一個標記，然后覆蓋fillColor，我該怎么辦？

謝謝

一種選擇是使用函數生成圖標（即createIcon函數），該函數將顏色作為參數並返回圖標匿名對象：

function createIcon(color) {
  return {
    path: 'M12 2C8.13 2 5 5.13 5 9c0 5.25 7 13 7 13s7-7.75 7-13c0-3.87-3.13-7-7-7zm0 9.5c-1.38 0-2.5-1.12-2.5-2.5s1.12-2.5 2.5-2.5 2.5 1.12 2.5 2.5-1.12 2.5-2.5 2.5z',
    fillColor: color,
    fillOpacity: 0.95,
    scale: 2,
    strokeColor: '#fff',
    strokeWeight: 3,
    anchor: new google.maps.Point(12, 24)
  };
}

然后在創建標記時使用它：

var marker1 = new google.maps.Marker({
    map: map,
    position: {
      lat: 37.448,
      lng: -122.143
    },
    icon: createIcon('#ff61b4')
  });

概念證明

代碼段：

 function createIcon(color) { return { path: 'M12 2C8.13 2 5 5.13 5 9c0 5.25 7 13 7 13s7-7.75 7-13c0-3.87-3.13-7-7-7zm0 9.5c-1.38 0-2.5-1.12-2.5-2.5s1.12-2.5 2.5-2.5 2.5 1.12 2.5 2.5-1.12 2.5-2.5 2.5z', fillColor: color, fillOpacity: 0.95, scale: 2, strokeColor: '#fff', strokeWeight: 3, anchor: new google.maps.Point(12, 24) }; } 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 marker = new google.maps.Marker({ map: map, position: map.getCenter(), icon: createIcon('blue') }); var marker1 = new google.maps.Marker({ map: map, position: { lat: 37.448, lng: -122.143 }, icon: createIcon('#ff61b4') }) var marker2 = new google.maps.Marker({ map: map, position: { lat: 37.44, lng: -122.148 }, icon: createIcon('#05950a') }); } google.maps.event.addDomListener(window, "load", initialize); 

 html, body, #map_canvas { height: 100%; width: 100%; margin: 0px; padding: 0px } 

 <script src="https://maps.googleapis.com/maps/api/js"></script> <div id="map_canvas"></div>

您可以使用setOptions，例如：僅更改圖標

marker.setOptions({
     icon = "http://labs.google.com/ridefinder/images/mm_20_white.png"
});

或可點擊

marker.setOptions({clickable:false});

因此您可以對所有標記選項執行相同的操作
