Google地图v3上的可点击行驶方向

Question

我正在制作谷歌地图项目,需要创建一个点击它的路线.

我的项目有2个点有一个预定义的lat和lng,我想自己画A点和B点的开始和结束,不要失去它的功能.

我做了另一个项目,你可以点击绘制路线,但它没有标记,并且不可拖动,这是我的实际项目与完整的代码我将在这里发布一个短代码只与我的方向.

我希望我第一次点击A点,第二点点B,他们可以拖动它们,就像项目链接一样

function goma()
{   
    var mapDiv = document.getElementById('mappy');
    var mapOptions = {
    zoom: 12, 
    center: new google.maps.LatLng(-23.563594, -46.654239),
    mapTypeId : google.maps.MapTypeId.ROADMAP
    }
    pode ser ROADMAP, SATELLITE, HYBRID, TERRAIN
    map = new google.maps.Map( mapDiv, mapOptions ); 

    //Render route, etc.
    ren = new google.maps.DirectionsRenderer( {'draggable':true} );
    ren.setMap(map);
    ren.setPanel(document.getElementById("directionsPanel"));
    ser = new google.maps.DirectionsService();

    //Create the route
    ser.route({ 'origin': new google.maps.LatLng(-23.563594, -46.654129), 'destination':  new google.maps.LatLng(
-23.563672, -46.640396), 'travelMode': google.maps.DirectionsTravelMode.DRIVING},function(res,sts) {
        if(sts=='OK')ren.setDirections(res);    
    })      

}   

我在这里更新我的代码,我只做了wayA,这是第一个航点,第二个是latLng预定义,你点击它,它得到latLng并放入'origin'.

    google.maps.event.addListener(map, "click", function(event) {
            wayA = new google.maps.Marker({ 
              position: event.latLng,
              map: map                
            });
     });
    ren = new google.maps.DirectionsRenderer( {'draggable':true} );
    ren.setMap(map);
    ren.setPanel(document.getElementById("directionsPanel"));
    ser = new google.maps.DirectionsService();          
    ser.route({ 'origin': wayA, 'destination':  new google.maps.LatLng(
-23.563672, -46.640396), 'travelMode': google.maps.DirectionsTravelMode.DRIVING},function(res,sts) {
        if(sts=='OK')ren.setDirections(res);    
    })      

这是我对完整代码的测试

Answer 1

概念:(听起来这就是你想要的)

1. 向地图添加单击事件侦听器
2. 当用户点击地图时添加一个可拖动的标记(我会添加一个点击监听器,以便他们可以通过点击删除它)
3. 当用户第二次点击地图时添加第二个可拖动标记
4. 添加第二个标记时,使用两个标记的位置调用路线服务.
5. 如果拖动任一标记,请再次调用路线服务.

(如果这是你正在尝试并遇到问题,代码或实时链接会有帮助)

你缺少#3和#4

工作实例

代码段:

var map, ren, ser;
var data = {};
var data2 = {};
var marker;
var infowindow;
var doMark = true;
var directionsDisplay;

var wayA;
var wayB;

//Função de Inicio

function goma() {

  var mapDiv = document.getElementById('mappy');

  var mapOptions = {
      zoom: 12,

      center: new google.maps.LatLng(-23.563594, -46.654239),
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    //Cria o mapa do google, coloca as definições do mapa, como tipo de visualização, pode ser ROADMAP, SATELLITE, HYBRID, TERRAIN
  map = new google.maps.Map(mapDiv, mapOptions);


  var control = document.createElement('DIV');
  control.style.padding = '1px';
  control.style.border = '1px solid #000';
  control.style.backgroundColor = 'white';
  control.style.cursor = 'pointer';
  control.innerHTML = '<img src="http://i47.tinypic.com/2dlp2fc.jpg" border="0" alt="Image and video hosting by TinyPic">';
  control.index = 1;


  map.controls[google.maps.ControlPosition.TOP_RIGHT].push(control);

  google.maps.event.addDomListener(control, 'click', function() {
    doMark = false;
    markNow();


  });

  google.maps.event.addListener(map, "click", function(event) {
    if (!wayA) {
      wayA = new google.maps.Marker({

        position: event.latLng,
        map: map

      });
    } else {
      wayB = new google.maps.Marker({

        position: event.latLng,
        map: map

      });

      //Renderiza a rota, o draggable é diz se o waypoint é arrastavel ou não
      ren = new google.maps.DirectionsRenderer({
        'draggable': true
      });
      ren.setMap(map);
      ren.setPanel(document.getElementById("directionsPanel"));
      ser = new google.maps.DirectionsService();

      //Cria a rota, o DirectionTravelMode pode ser: DRIVING, WALKING, BICYCLING ou TRANSIT
      ser.route({
        'origin': wayA.getPosition(),
        'destination': wayB.getPosition(),
        'travelMode': google.maps.DirectionsTravelMode.DRIVING
      }, function(res, sts) {
        if (sts == 'OK') ren.setDirections(res);
      })

    }
  });
}
