从传单路由机获取航点 [英] Getting waypoints from leaflet routing machine

问题描述

我正在尝试从路线(小叶路线选择机)获取经度和纬度的航路点，以便将其写到数据库中.但是，当我呼叫getwaypoints时，我还会获得有关我不想要的路线的更多数据.

I'm trying to get the waypoints from a route (leaflet routing machine) as latitude and longitude so I can write these out to a database. However when I call getwaypoints I also get additional data about the route that I don't want.

我如何只获取经度/纬度的JSON，以便可以将其写到db中?

How do i get just the lat/long as JSON so I can write it out to a db?

    var map = L.map('map').setView([-27.54, 152.9], 10);
    L.tileLayer('http://{s}.basemaps.cartocdn.com/light_all//{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> &copy; <a href="http://cartodb.com/attributions">CartoDB</a>',
    maxZoom: 19
}).addTo(map);

var routeControl = L.Routing.control({waypoints: [
    L.latLng(-27.38851, 153.11606),
    L.latLng(-27.47577, 153.01693)
  ]}).addTo(map);

  var routeArray = new Array();
  routeArray = routeControl.getWaypoints();

  alert (JSON.stringify(routeArray));

输出

[{"options":{"allowUTurn":false},"latLng":{"lat":-27.38851,"lng":153.11606},"_initHooksCalled":true},{"options":{"allowUTurn":false},"latLng":{"lat":-27.47577,"lng":153.01693},"_initHooksCalled":true}]

推荐答案

解决方案无法转换为JSON

alert (routeArray[0].latLng.lng);
