如何使用turf.js与ionic

Question

我是离子的新手，并试图在离子应用中使用草皮。首先，我通过npm使用

安装它

npm install turf

在节点模块中添加草皮文件夹。我复制了这个在lib文件夹。然后我在索引页添加了turf.min.js的链接。

给出这个错误

turf.featurecollection is not a function

使用的代码-

  var features = [
            turf.point([-97.502754, 35.463455], {
                "marker-color": "#6BC65F",
                "title": "Too Far",
                "marker-size": "small"
            }),
            turf.point([-97.508269, 35.463245], {

        var nearest_fc = turf.featurecollection([point, nearest]);
        var map = L.mapbox.map('map', 'charuoshan.0n1b363n')
            .setView([35.463453, -97.508014], 14);
        L.mapbox.featureLayer().setGeoJSON(fc).addTo(map);
        L.mapbox.featureLayer().setGeoJSON(nearest_fc).addTo(map);

Answer 1

看起来像是一个简单的打字错误。应该是featureCollection
