Leaflet 使用GeoJson数据更改传单地图中的标记

我用传单和GeoJSON构建了一个网络地图。我想更改标记，但是传单站点的示例对我没有帮助，因为它是用于本地文件的。你知道怎么改吗

$.getJSON("https://gist.githubusercontent.com/vassilaros/3791204ca226d5b236b4cd3106ef23cf/raw/PicnicSites.geojson", function(data) { addDataToMap(data, map); });

及

我想把

{icon:greenIcon}

添加到我的图层中。 我必须添加这行代码吗

EDIT2:

我要更改此标记：

只需使用pointToLayer函数

  var MyIcon = L.icon({
    iconUrl: 'leaf-green.png',
    iconSize:     [38, 95], // size of the icon
    shadowSize:   [50, 64], // size of the shadow
    iconAnchor:   [22, 94], // point of the icon which will correspond to marker's location
    shadowAnchor: [4, 62],  // the same for the shadow
    popupAnchor:  [-3, -76] // point from which the popup should open relative to the iconAnchor
});

  L.geoJson(data  ,{
    pointToLayer: function(feature,latlng){
      return L.marker(latlng,{icon: MyIcon});
    }
  }).addTo(map);

你想用哪一点替换哪一点？可能重复的我认为你的json无效。你想用哪一点替换哪一点？可能重复的我认为你的json无效。poinToLayer可能是解决方案。我发现这个问题和我的问题很接近。点图层可能是解决方案。我发现这个问题和我的问题很接近。
