rebuild-position-list

对地图点位数组数据进行重构。添加lonLat经纬度数组字段。并移除经纬度脏数据。防止地图渲染异常

Install

yarn add rebuild-position-list
import changeLonLat from 'rebuild-position-list'
const list1 = [
  {
    lon: '1', lat: '2'
  },
  {
    lon: '1.366346463', lat: '2.34234234223'
  },
  {
    lon: '1.366346463w', lat: '2.34234234223'
  }
]
changeLonLat(list1)
输出
[
  {
    "lon": "1",
    "lat": "2",
    "lonLat": [
      1,
      2
    ]
  },
  {
    "lon": "1.366346463",
    "lat": "2.34234234223",
    "lonLat": [
      1.366346463,
