谷歌地图V3可点击驾驶方向(Clickable Driving Direction on Googl

2019-06-26 15:51发布

我在做一个谷歌地图项目,需要在其上创建一个路由点击。

我的项目有2个,有一个预定义的纬度和经度,我想通过自己抽的开始和点A和B的结束,不要失去它的功能。

我做了另一个项目,您可以单击绘制路线,但它没有标记,并且不draggabble, 这是我的实际项目与完整的代码,我将在这里发表一个简短的代码只能用我的方向。

我想,我的第一次点击的A点和第二点我B,并可能拖累他们,像项目链接

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);    
    })      

}   

我更新这里我的代码,我只是做了哇呀,这是第一个航点,第二个是一个预定义的latLng,在那里你点击,它得到的经纬度,并把“原点”里面。

    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);    
    })      

这是我测试用的完整代码

Answer 1:

概念:(听起来好像这是你想要的)

  1. 添加一个click事件侦听到地图
  2. 当用户点击地图上添加一个拖动的标记(我会点击监听器添加到它,使他们可以通过点击删除)
  3. 当用户点击地图上的第二次添加的第二拖动的标记
  4. 加入第二标记时,调用指示服务与两个标记的位置。
  5. 如果任一标志被拖到再次调用导航服务。

(如果你正在尝试并遇到了问题,代码或活链接将是有益的)

这是因为丢失#3,#4
