IDW空间插值法

Question

我正在使用此插件来执行IDW插值方法。但是，当我使用自己的数据时，错误是" IDW不是函数"

function idw(geojson) {
  debugger;
  coords = []; //define an array to store coordinates
  onEachFeature: function (geojson.feature, geojsonLayer) {
     // popupOptions = {maxWidth: 200};
     // layer.bindPopup(feature.properties.popupContent);
     coords.push(feature.geometry.coordinates);
   }
  for (var i=0; i<coords.length; i++) {
    var lat = coords[i][0];
    var lon = coords[i][1];
    var intensity = coords[i][2];
    var markerLocation = new L.LatLng(lat, lon);
    var marker = new L.Marker(markerLocation).bindPopup(popupText).addTo(map);
  }
  var idw = L.idwLayer(coords, {
    opacity: 0.3,
    maxZoom: 18,
    cellSize: 10,
    exp: 3,
    max: 1200
  });
  map.addLayer(idwLayer);
}

我遇到了相同的问题并使其正常工作，我刚刚添加：

<script src="js/leaflet-idw+directdraw.js"></script>
