Question

我试图在我的谷歌地图api上使用叠加显示一组停车图标，但由于某种原因无法使其工作。

我为我的html here创建了一个js小提琴。这是它的开始：

  function setMarkers(map, locations) {

      var image = new google.maps.MarkerImage('parkingIcon.png');
  };

感谢任何帮助。感谢。

好的，试试这段代码：

        height: 100%
      }
      body {
        height: 100%;
        margin: 0;
        padding: 0
      }
      #map_canvas {
        height: 100%
      }

您的parkingIcon需要一个URL，它在jsfiddle中不起作用;如果它位于本地目录中，它可能适用于您的站点。

您需要实际处理数组并创建标记，此代码不会执行任何有用的操作：

function setMarkers(map, locations) {
var image = new google.maps.MarkerImage('parkingIcon.png');
};

这样的事情会更好：

function setMarkers(map, locations) {

  var image = new google.maps.MarkerImage('http://maps.google.com/mapfiles/ms/icons/parkinglot.png');
  for (var i=0; i<locations.length; i++)
  {
    var marker = new google.maps.Marker({
      icon: 'http://maps.google.com/mapfiles/ms/icons/parkinglot.png', 
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),
      title: locations[i][0],
      map: map
    });
  }
 };

您需要将“parking”数组传递给函数（位置是未定义的单个元素）。
