Google Maps v3在两点之间创建路线 [英] Google Maps v3 Create routes between two points

问题描述

我正在使用Google地图API开发Web应用程序。我试图创建一个两点之间的路线，但由于某种原因，我还没有想出如何创建它。以下是我的代码，请让我知道是否有我缺少的东西。谢谢。

 < script> 
 var Center = new google.maps.LatLng（18.210885，-67.140884）; 
 var directionsDisplay; 
 var directionsService = new google.maps.DirectionsService（）; 
 var map; 
 
函数initialize（）{
 directionsDisplay = new google.maps.DirectionsRenderer（）; 
 var properties = {
 center：Center，
 zoom：20，
 mapTypeId：google.maps.MapTypeId.SATELLITE 
}; 
 
 map = new google.maps.Map（document.getElementById（map），properties）; 
 directionsDisplay.setMap（map）; 
 
 var marker = new google.maps.Marker（{
 position：Center，
 animation：google.maps.Animation.BOUNCE，
}）; 
 
 marker.setMap（map）; 
 
 
 
函数Route（）{
 
 var start = new google.maps.LatLng（18.210885，-67.140884）; 
 var end = new google.maps.latLng（18.211685，-67.141684）; 
 var request = {
 origin：start，
 destination：end，
 travelMode：google.maps.TravelMode.WALKING 
}; 
 directionsService.route（request，function（result，status）{
 if（status == google.maps.DirectionsStatus.OK）{
 directionsDisplay.setDirections（result）; 
 } 
}）; 
} 
 
 google.maps.event.addDomListener（window，'load'，initialize）; 
< / script> 
  

解决方案

1. 呼叫路线功能
   

2. 更改：
   
   

     var end = new google.maps.latLng（18.211685，-67.141684）; 
     

到：

  var end = new google.maps.LatLng（18.211685，-67.141684）; 
  

（javascript区分大小写，浏览器在javascript控制台中报告错误）

代码片段：

var Center = new google.maps.LatLng（18.210885，-67.140884）; var directionsDisplay; var directionsService = new google。 maps.DirectionsService（）; var map;函数initialize（）{directionsDisplay = new google.maps.DirectionsRenderer（）; var properties = {center：Center，zoom：20，mapTypeId：google.maps.MapTypeId.SATELLITE}; map = new google.maps.Map（document.getElementById（map），properties）; directionsDisplay.setMap（地图）; var marker = new google.maps.Marker（{position：Center，animation：google.maps.Animation.BOUNCE，}）; marker.setMap（地图）; Route（）;}函数Route（）{var start = new google.maps.LatLng（18.210885，-67.140884）; var end = new google.maps.LatLng（18.211685，-67.141684）; var request = {origin：start，destination：end，travelMode：google.maps.TravelMode.WALKING}; directionsService.route（request，function（result，status）{if（status == google.maps.DirectionsStatus.OK）{directionsDisplay.setDirections（result）;} else {alert（could not get directions：+ status） ;}}）;} google.maps.event.addDomListener（window，'load'，initialize）;

  html，body，＃map {margin：0;填充：0; height：100％;}

I'm using the Google Maps API to develop a web application. I am trying to create a route between two points but for some reason I haven't figured out how create it. Below is my code, please let me know if there is something I am missing. Thank you.

<script>
var Center=new google.maps.LatLng(18.210885,-67.140884);
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;

function initialize() {
  directionsDisplay = new google.maps.DirectionsRenderer();
var properties = {
    center:Center,
    zoom:20,
    mapTypeId:google.maps.MapTypeId.SATELLITE
};

map=new google.maps.Map(document.getElementById("map"), properties);
directionsDisplay.setMap(map);

var marker=new google.maps.Marker({
position:Center,
animation:google.maps.Animation.BOUNCE,
});

marker.setMap(map);

}

function Route() {

var start = new google.maps.LatLng(18.210885,-67.140884);
var end =new google.maps.latLng(18.211685,-67.141684);
var request = {
origin:start,
destination:end,
travelMode: google.maps.TravelMode.WALKING
 };
 directionsService.route(request, function(result, status) {
if (status == google.maps.DirectionsStatus.OK) {
  directionsDisplay.setDirections(result);
}
});
} 

google.maps.event.addDomListener(window,'load',initialize);
</script>

解决方案

It works for me if I:

1. call the Route function

2. change:

   var end =new google.maps.latLng(18.211685,-67.141684);
   

to:

    var end =new google.maps.LatLng(18.211685,-67.141684);

(javascript is case sensitive, the browser reported the error in the javascript console)

working version

code snippet:

var Center = new google.maps.LatLng(18.210885, -67.140884);
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;

function initialize() {
  directionsDisplay = new google.maps.DirectionsRenderer();
  var properties = {
    center: Center,
    zoom: 20,
    mapTypeId: google.maps.MapTypeId.SATELLITE
  };

  map = new google.maps.Map(document.getElementById("map"), properties);
  directionsDisplay.setMap(map);

  var marker = new google.maps.Marker({
    position: Center,
    animation: google.maps.Animation.BOUNCE,
  });

  marker.setMap(map);
  Route();
}

function Route() {

  var start = new google.maps.LatLng(18.210885, -67.140884);
  var end = new google.maps.LatLng(18.211685, -67.141684);
  var request = {
    origin: start,
    destination: end,
    travelMode: google.maps.TravelMode.WALKING
  };
  directionsService.route(request, function(result, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(result);
    } else {
      alert("couldn't get directions:" + status);
    }
  });
}

google.maps.event.addDomListener(window, 'load', initialize);

html,
body,
#map {
  margin: 0;
  padding: 0;
  height: 100%;
}
