将ID添加到Google地图标记

81

我有一个脚本，可以一次循环并添加一个标记。

我正在尝试使当前标记具有一个信息窗口，并且一次在地图上仅具有5个标记（4个没有信息窗口，而1个带有信息窗口）

如何为每个标记添加ID，以便可以根据需要删除和关闭信息窗口。

这是我用来设置标记的功能：

function codeAddress(address, contentString) {

var infowindow = new google.maps.InfoWindow({
  content: contentString
});

if (geocoder) {

  geocoder.geocode( { 'address': address}, function(results, status) {

    if (status == google.maps.GeocoderStatus.OK) {

        map.setCenter(results[0].geometry.location);

       var marker = new google.maps.Marker({
          map: map, 
          position: results[0].geometry.location
       });

       infowindow.open(map,marker);

      } else {
       alert("Geocode was not successful for the following reason: " + status);
      }
    });
  }

}

JavaScript是一种动态语言。您可以将其添加到对象本身。

var marker = new google.maps.Marker(markerOptions);
marker.metadata = {type: "point", id: 1};

同样，因为所有v3对象都将扩展MVCObject()。您可以使用：

marker.setValues({type: "point", id: 1});
// or
marker.set("type", "point");
marker.set("id", 1);
var val = marker.get("id");

我很好奇，一旦给了标记id，您将如何在地图画布之外访问这些标记。$（'＃1'）。doSomething（）; 例如？

@willdanceforfun将点击事件添加到标记中并获得有关以下信息this：google.maps.event.addListener(yourMarker, 'click', function (event) { console.log(this); });

只需添加另一个对我有用的解决方案即可。您只需将其添加到标记选项中即可：

var marker = new google.maps.Marker({
    map: map, 
    position: position,

    // Custom Attributes / Data / Key-Values
    store_id: id,
    store_address: address,
    store_type: type
});

然后使用以下命令检索它们：

marker.get('store_id');
marker.get('store_address');
marker.get('store_type');

这帮了一大堆。这些示例都没有。适用于通过点击返回功能传递消费价值。

我有一个简单的Location类，用于处理所有与标记有关的事情。我将在下面粘贴我的代码，以供您参考。

最后一行是实际创建标记对象的内容。它遍历我位置的一些JSON，如下所示：

{"locationID":"98","name":"Bergqvist Järn","note":null,"type":"retail","address":"Smidesvägen 3","zipcode":"69633","city":"Askersund","country":"Sverige","phone":"0583-120 35","fax":null,"email":null,"url":"www.bergqvist-jb.com","lat":"58.891079","lng":"14.917371","contact":null,"rating":"0","distance":"45.666885421019"}

这是代码：

如果您查看target()我的Location类中的方法，您会发现我保留了对信息窗口的引用，open()并且close()由于引用而可以简单地将它们和它们引用。

        self.rating_class = 'blue';

        // this is the marker point
        self.point = new google.maps.LatLng(parseFloat(self.lat), parseFloat(self.lng));
        locator.bounds.extend(self.point);

        // Create the marker for placement on the map

为什么不使用存储每个标记对象并引用ID的缓存？

var markerCache= {};
var idGen= 0;

function codeAddress(addr, contentStr){
    // create marker
    // store
    markerCache[idGen++]= marker;
}

编辑：当然，这依赖于不提供长度属性（如数组）的数字索引系统。当然，您可以为此类对象原型化对象并创建长度等。OTOH，可能为每个地址生成唯一的ID值（MD5等）。
