Google地图点击路线上的事件 [英] Google Maps click event on route

本文介绍了Google地图点击路线上的事件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

无论我点击哪条路线，我都想画一个圆圈。我寻找一个解决方案，如何使路由可点击，并找不到有用的东西...下面是我的代码。 

  directionsDisplay = new google.maps.DirectionsRenderer（rendererOptions（））;我点击路线时没有错误，但没有创建圆圈。
 ）; 
 
 //在这里指示服务请求... 
 
 google.maps.event.addListener（directionsDisplay，'click'，function（event）{
 
 var routeClick = new google.maps.Circle（{
 center：event.latLng，// center你点击
半径：500，
 strokeColor：＃0000FF，
 strokeOpacity：0.8，
 strokeWeight：2，
 fillColor：＃0000FF，
 fillOpacity：0.4 
}）; 
 
 routeClick.setMap （地图）; 
 
}）;

更新：

工作代码根据Geocodezip的脚本创建自己的方向折线 http://www.geocodezip.com/v3_directions_custom_iconsC.html和官方API示例 https://developers.google.com/maps/documentation/javascript/例子/高程路径 

  //绘制路径
函数drawPath（path）{
 //显示高程路径的折线。 
 var pathOptions = {
 path：path，
 strokeColor：'＃0000CC'，
 strokeWeight：5，
 opacity：0.4，
 map：map 
} 
 routePolyline = new google.maps.Polyline（pathOptions）; 
}

然后在我添加的directionService请求中

  directionService.route（request，function（result，status）{
 var path = result.routes [0] .overview_path; 
 drawPath（路径）; 
}）;


解决方案

上没有'click'事件href =https://developers.google.com/maps/documentation/javascript/reference#DirectionsRenderer =noreferrer> DirectionsRenderer



你可以自己渲染多段线，并为其添加单击事件侦听器或向地图添加单击侦听器。

I'm trying to draw a circle wherever I click on the route. I looked for a solution on how to make a route clickable and couldn't find anything helpful... Below is my code. I get no errors when I click on the route but no circle is created.

directionsDisplay = new google.maps.DirectionsRenderer(rendererOptions);

//direction service request here...

google.maps.event.addListener(directionsDisplay, 'click', function(event) {

var routeClick = new google.maps.Circle({
  center: event.latLng, //center where you click
  radius: 500,
  strokeColor: "#0000FF",
  strokeOpacity: 0.8,
  strokeWeight: 2,
  fillColor: "#0000FF",
  fillOpacity: 0.4
});

routeClick.setMap(map);

});

UPDATE:

Working code to create your own directions polyline based on Geocodezip's script http://www.geocodezip.com/v3_directions_custom_iconsC.html and official API example https://developers.google.com/maps/documentation/javascript/examples/elevation-paths

    // Draw the path
    function drawPath(path) {
      // Display a polyline of the elevation path.
      var pathOptions = {
        path: path,
        strokeColor: '#0000CC',
        strokeWeight: 5,
        opacity: 0.4,
        map: map
      }
      routePolyline = new google.maps.Polyline(pathOptions);
    }

then in the directionService request I added

directionService.route(request, function(result, status) {
  var path = result.routes[0].overview_path;  
  drawPath(path);
});

解决方案

There is no 'click' event on the DirectionsRenderer

you can render the polyline yourself and add a click event listener to it or add a click listener to the map.

Example of a custom directions renderer

proof of concept fiddle

code snippet:

var infowindow = new google.maps.InfoWindow();
var directions = new google.maps.DirectionsService();
var renderer = new google.maps.DirectionsRenderer({
  suppressPolylines: true,
  infoWindow: infowindow,
});
var map;

function initialize() {
  var mapOptions = {
    zoom: 13,
    center: new google.maps.LatLng(40.7482333, -73.8681295),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };

  map = new google.maps.Map(document.getElementById('map'), mapOptions);

  google.maps.event.addDomListener(document.getElementById('go'), 'click',
    route);

  var input = document.getElementById('from');
  var autocomplete = new google.maps.places.Autocomplete(input);
  autocomplete.bindTo('bounds', map);
  route();
}

function route() {
  var request = {
    origin: document.getElementById('from').value,
    destination: '51 St, New York, NY 10022, USA',
    travelMode: google.maps.DirectionsTravelMode.WALKING
  };

  var panel = document.getElementById('panel');
  panel.innerHTML = '';
  directions.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      renderer.setDirections(response);
      renderer.setMap(map);
      renderer.setPanel(panel);
      renderDirectionsPolylines(response);
      console.log(renderer.getDirections());
    } else {
      renderer.setMap(null);
      renderer.setPanel(null);
    }

  });

}

var polylineOptions = {
  strokeColor: '#C83939',
  strokeOpacity: 1,
  strokeWeight: 4
};
var polylines = [];
function renderDirectionsPolylines(response) {
  for (var i=0; i<polylines.length; i++) {
    polylines[i].setMap(null);
  }
  var legs = response.routes[0].legs;
  for (i = 0; i < legs.length; i++) {
    var steps = legs[i].steps;
    for (j = 0; j < steps.length; j++) {
      var nextSegment = steps[j].path;
      var stepPolyline = new google.maps.Polyline(polylineOptions);
      for (k = 0; k < nextSegment.length; k++) {
        stepPolyline.getPath().push(nextSegment[k]);
      }
      polylines.push(stepPolyline);
      stepPolyline.setMap(map);
      // route click listeners, different one on each step
      google.maps.event.addListener(stepPolyline, 'click', function(evt) {
        infowindow.setContent("you clicked on the route<br>" + evt.latLng.toUrlValue(6));
        infowindow.setPosition(evt.latLng);
        infowindow.open(map);
      })
    }
  }
}
google.maps.event.addDomListener(window, 'load', initialize);
