leaflet 加载geojson 出现 Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'. 解决办法

在加载geojson文件时报错 ： Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node' 如图所示：

以下是 geojson文件格式

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "name": 0
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    101.7581977222,
                    36.8348153089
                ]
            }
        },

错误原因是 "properties"的格式错误"name": 0 零应双引号括起来。

js。代码片段

 for (let i = 0; i < excelConvertArr.length; i++) {
                        //excel文件数据格式纬度在前而Geojson格式是经度在前这里进行转换
                        var x = excelConvertArr[i][0];
                        var y = excelConvertArr[i][1];
                        var coordinate = [y, x];
                        var properties = { name:  i}
                        var pointToFeature = this._pointToFeature(coordinate, properties)
                        lnglat.push(pointToFeature);                      
                    }

错误代码为

下面展示一些 内联代码片。

  var properties = { name:  i}

将var properties = { name: i}更改为

 var properties = { name:  `${i}` }

问题解决 修改后的 geojson代码片。

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "name": "0"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    101.7581977222,
                    36.8348153089
                ]
            }
        },

"name": "0"加双引号后问题解决。
