我正在尝试将我的数组解析为代表这样的数据
-1.80511,53.84632:-1.80511,53.84632:-1.80511,53.84632:xxx,xxx:xxx
lat,lng:lat,lng
这样它就可以被api读取。这是我到目前为止的代码,我只能把它变成这种格式(coordsnew)
-1.7651,53.88566,-1.76896,53.8866,-1.77125,53.88801
我当前的代码
var coordsnew = [];
var i;
for (i = 0; i < coords.length; i++) {
coordsnew += coords[i];
console.log(coordsnew);
我的coords数组数据目前是这样形成的
var statesdata = {

这是数据的传递方式以及它在控制台中的表示方式
var coords = layer.feature.geometry.coordinates;
0:Array(1)
0:Array(94)
0:Array(2) [-1.75937311731598, 53.808343451011]
0:-1.75937311731598
1:53.808343451011
答案 0 :(得分:0)
获取所需的字符串:
var colonString = statesdata
.features[0]
.properties
.geometry
.coordinates[0][0]
.map(pair => pair.reverse().join())
.join(':');
这是一些深度嵌套的geoJSON。
