创建 mapbox 地图后如何更新 GeoJSON？

Question

我有这个html：

<div id="clickthis"><p>addGeoJSON</p></div>
<div id='raw'></div>
<div id='map'></div>

这是我的 javascript 代码：

var geojson = [
  {
    "type": "Feature",
    "geometry": {
      "type": "Point",
      "coordinates": [-77.03238901390978,38.913188059745586]
    },
    "properties": {
      "title": "Mapbox DC",
      "description": "1714 14th St NW, Washington DC",
      "marker-color": "#fc4353",
      "marker-size": "large",
      "marker-symbol": "monument"
    }
  },
  {
    "type": "Feature",
    "geometry": {
      "type": "Point",
      "coordinates": [-122.414, 37.776]
    },
    "properties": {
      "title": "Mapbox SF",
      "description": "155 9th St, San Francisco",
      "marker-color": "#fc4353",
      "marker-size": "large",
      "marker-symbol": "harbor"
    }
  }
];
L.mapbox.accessToken = 'pk.eyJ1IjoibWFwcGllc3RpY2tlciIsImEiOiJIn0.IgCoorxIUvE0CjcPriROeQ';
var map = L.mapbox.map('map', 'mappiesticker.kh78ogof').setView([34, -118.50], 9);

$('#clickthis').click(function(){
  alert('alkr');
  dataLayer = L.mapbox.featureLayer(geojson);
  dataLayer.addTo(map);
})

当我单击 div 时会触发警报，但没有其他任何反应。我尝试使用 .setGeoJSON 函数，但它返回未定义。我得出的结论是，这仅在您创建地图时使用，而不是在创建后添加 GeoJSON

我在使用您的令牌时遇到 401 错误：

Failed to load resource: the server responded with a status of 401 (Unauthorized)

当我将您的代码与 Mapbox 的示例令牌和地图一起使用时（请注意，您应该使用自己的令牌和地图）它非常好：

L.mapbox.accessToken = 'pk.eyJ1IjoicGF1bC12ZXJob2V2ZW4iLCJhIjoiZ1BtMWhPSSJ9.wQGnLyl1DiuIQuS0U_PtiQ';

var map = L.mapbox.map('mapbox', 'examples.map-i86nkdio', {
    'center': [0, 0],
    'zoom': 1
});

我会仔细检查您的帐户令牌和地图 ID。
