我想使用可拖动的航路点显示多个方向,并在调用 Route.prototype.setWayPoints() 时将每个航路点与起点、目标关联到对象或数据库中。
这家伙正在使用带有可拖动航点的单条路线(并将它们保存在数据库中)。
我想要多条路线而不是一条。我用谷歌搜索了很多,但找不到任何东西!
这是我尝试过的。
function Route(origin, destination){
this.origin = origin; // LatLng
this.destination = destination; //LatLng
this.way_points = null;
};
Route.prototype.drawRoute = function(){
this.dser.route({'origin': this.origin,
'destination': this.destination,
'waypoints': this.way_points,
'travelMode': google.maps.DirectionsTravelMode.DRIVING},
function(res,sts) {
if(sts=='OK'){
var dren = new google.maps.DirectionsRenderer({ 'draggable':true });
dren.setMap(map); //global variable 'map'
dren.setDirections(res);
}
});
};
Route.prototype.setGMap = function(map){
this.dren.setMap(map);
};
Route.prototype.setWayPoints = function(){
this.way_points = //... what should I do?
};
/* --- main part --- */
r0 = new Route(new google.maps.LatLng( 30, 31 ), new google.maps.LatLng( 40, 41 ));
r0.drawRoute();
// User drags and drops the route on the browser
r0.setWayPoints(); // newly added waypoints should be stored in r0.way_points
r1 = new Route(new google.maps.LatLng( 50, 51 ), new google.maps.LatLng( 60, 61));
r1.drawRoute();
// User drags and drops the route on the browser
r1.setWayPoints(); // newly added waypoints should be stored in r1.way_points
谁能告诉我如何实现 Route.prototype.setWayPoints 以便当前 googlemap 上的路线中的航点可以存储在 Route 对象中?
