如何添加獨特的鏈接到谷歌地圖標記

Question

我只是想弄清楚如何添加獨特的鏈接到每個谷歌地圖標記。

我試着向每個位置數組項添加第三個值，然後將url：locations [2]添加到新的google maps類，但它只是打破了地圖。

我有以下的JS ...

  function initMap() { 

      var centerPoint = { lat: 51.6856885, lng: -3.6304398 }; 

      var map = new google.maps.Map(document.getElementById('map'), { 
       zoom: 10, 
       center: centerPoint, 
       styles: [{ "featureType": "all", "elementType": "labels.text.fill", "stylers": [{ "color": "#ffffff" }] }, { "featureType": "all", "elementType": "labels.text.stroke", "stylers": [{ "visibility": "on" }, { "color": "#424b5b" }, { "weight": 2 }, { "gamma": "1" }] }, { "featureType": "all", "elementType": "labels.icon", "stylers": [{ "visibility": "off" }] }, { "featureType": "administrative", "elementType": "geometry", "stylers": [{ "weight": 0.6 }, { "color": "#545b6b" }, { "gamma": "0" }] }, { "featureType": "landscape", "elementType": "geometry", "stylers": [{ "color": "#545b6b" }, { "gamma": "1" }, { "weight": "10" }] }, { "featureType": "poi", "elementType": "geometry", "stylers": [{ "color": "#666c7b" }] }, { "featureType": "poi.park", "elementType": "geometry", "stylers": [{ "color": "#545b6b" }] }, { "featureType": "road", "elementType": "geometry", "stylers": [{ "color": "#424a5b" }, { "lightness": "0" }] }, { "featureType": "transit", "elementType": "geometry", "stylers": [{ "color": "#666c7b" }] }, { "featureType": "water", "elementType": "geometry", "stylers": [{ "color": "#2e3546" }] }] 
      }); 

      // Create an array of alphabetical characters used to label the markers. 
      var labels = ''; 

      // Add some markers to the map. 
      // Note: The code uses the JavaScript Array.prototype.map() method to 
      // create an array of markers based on a given "locations" array. 
      // The map() method here has nothing to do with the Google Maps API. 
      var markers = locations.map(function (location, i) { 
       return new google.maps.Marker({ 
        position: location, 
        label: labels[i % labels.length] 
       }); 
      }); 

      // Add a marker clusterer to manage the markers. 
      var markerCluster = new MarkerClusterer(map, markers, 
       { imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m' }); 
     } 
     var locations = [ 
      { lat: 51.5474973, lng: -3.5777395 }, 
      { lat: 51.4668561, lng: -3.1689607 }, 
      { lat: 51.6156059, lng: -3.6934229 }, 
      { lat: 51.5250486, lng: -3.6780919 }, 

      { lat: 51.6428655, lng: -3.9859831 }, 
      { lat: 51.5447132, lng: -3.5961878 }, 
      { lat: 51.5678233, lng: -3.2866061 }, 
      { lat: 51.5122641, lng: -3.5073934 }, 
      { lat: 51.4668561, lng: -3.1689607 } 
     ] 

Answer 1

如果我正確理解你的問題。您可以將第三個元素添加到您的位置數組項目中，但您無法直接按原樣使用它。你可以有

var locations = [ 
     { latLng:{lat: 51.5474973, lng: -3.5777395},url:'google.com' } 
] 

然後在功能做到這一點

return new google.maps.Marker({ 
    position: location.latLng, 
    url: location.url, 
    label: labels[i % labels.length] 
}); 

那麼URL將是每個標記對象。所以點擊一個標記，你可以調用this.url並獲得網址。
