Google Maps API(JS)在航点中使用PlaceId创建路线

[英]Google Maps API (JS) Create a route using PlaceId in waypoints

路由只有在我使用LatLng或String参数时才会创建,但我需要通过PlaceId创建它,但它不起作用

例:

directionsService.route({
        origin: {'placeId': 'ChIJc1lGdwfP20YR3lGOMZD-GTM'},
        destination: {'placeId': 'ChIJdTGhqsbP20YR6DZ2QMPnJk0'},
        waypoints: [{stopover: true, location: new google.maps.Place('ChIJRVj1dgPP20YRBWB4A_sUx_Q')}],
        optimizeWaypoints: true,
        travelMode: google.maps.TravelMode.DRIVING
    }

只需要将google.maps.Place对象作为航点位置传递即可。 例如:

directionsService.route({
    origin: { placeId: "ChIJc1lGdwfP20YR3lGOMZD-GTM" },
    destination: { placeId: "ChIJdTGhqsbP20YR6DZ2QMPnJk0" },
    waypoints: [{ stopover: true, location: { placeId: "ChIJRVj1dgPP20YRBWB4A_sUx_Q" } }],
    optimizeWaypoints: true,
    travelMode: google.maps.TravelMode.DRIVING
}

location指定航点的位置,LatLng,google.maps.Place对象或将进行地理编码的String。

这是JsFiddle

我发布的代码出现javascript错误: Uncaught TypeError: google.maps.Place is not a constructor此行Uncaught TypeError: google.maps.Place is not a constructor

waypoints: [{stopover: true, location: new google.maps.Place('ChIJRVj1dgPP20YRBWB4A_sUx_Q')}],

您需要以与origindestination placeIds相同的方式指定该location

waypoints: [{
  stopover: true,
  location: {'placeId':"ChIJRVj1dgPP20YRBWB4A_sUx_Q"}
}],

文档中的描述

Google.maps.Place对象规范

placeId | 类型:字符串地点的地点ID(例如商家或兴趣点)。 地点ID是Google地图数据库中地点的唯一标识符。 请注意,placeId是识别地点的最准确方式。 如果可能,您应该指定placeId而不是placeQuery。 可以从Places API的任何请求中检索地点ID,例如TextSearch。 也可以从对Geocoding API的请求中检索地点ID。 有关更多信息,请参阅地点ID概述

代码段:

 function initialize() { var map = new google.maps.Map(document.getElementById("map_canvas")); var directionsService = new google.maps.DirectionsService(); var directionsDisplay = new google.maps.DirectionsRenderer({ map: map }); directionsService.route({ origin: { 'placeId': 'ChIJc1lGdwfP20YR3lGOMZD-GTM' }, destination: { 'placeId': 'ChIJdTGhqsbP20YR6DZ2QMPnJk0' }, waypoints: [{ stopover: true, location: { 'placeId': "ChIJRVj1dgPP20YRBWB4A_sUx_Q" } }], optimizeWaypoints: true, travelMode: google.maps.TravelMode.DRIVING }, function(response, status) { if (status === 'OK') { directionsDisplay.setDirections(response); } else { window.alert('Directions request failed due to ' + status); } }); } google.maps.event.addDomListener(window, "load", initialize);
