在传单中显示具有属性的线字符串

Question

我希望可视化发送到传单/JavaScript应用程序的以下GeoJSON对象。如何可视化显示属性的所有线字符串。每个线条字符串的名称参数（例如，通过工具提示）。

{“features”：[{“type”：“Feature”，“properties”：{“name”：“0”}，“geometry”：{“type”：“LineString”，“坐标”：[[10.941445541381836,52.438697814941406]，[10.941454124450684,52.4387092590332]，[10.941451263427734,52.43870544433594]，[10.941441445541381836,52.438697814941406]，[10.941254806555.44073778516]，[10.941254806555]，{“type”，“properties”：}，“Feature”，“几何学”：{“类型”：“线串”，“坐标”：[[10.941445541381836,52.438697814941406]，[10.941454124450684,52.4387092590332]，[10.941451263427734,52.43870544433594]，[10.941445541381836,52.438697814941406]，[10.941254806518555,52.4407377778516]}}}

任何帮助都会很好！

谢谢

您没有正确使用GeoJSON。如果有多个要素，则应使用要素集合：https://geojson.org/geojson-spec.html

然后使用这个网站有正确的格式：https://jsonformatter.curiousconcept.com/

然后，如果您想添加工具提示，请参阅本教程：http://leafletjs.com/examples/geojson/

var geojsonFeature = {
   "type":"FeatureCollection",
   "features":[
      {
         "type":"Feature",
         "geometry":{
            "type":"LineString",
            "coordinates":[
