Vue Map - Add and Remove

To add routes at design-time, pass an array of objects to the routes property. A route requires only its locations to be specified. The locations will be connected and make up the route.

jQuery
JavaScript
$(function() {
    $("#mapContainer").dxMap({
        zoom: 5,
        routes: [{
            locations: [
                { lat: 40.782500, lng: -73.966111 },
                "40.755833, -73.986389",
                [ 40.753889, -73.981389 ],
                "Brooklyn Bridge,New York,NY"
            ]
        }]
    });

jQuery

To add or remove a route at runtime, call the addRoute(routeOptions) or removeRoute(route) method.

JavaScript
const routesCollection = [{
    locations: [ 
        "40.753889, -73.981389",
        "Brooklyn Bridge,New York,NY"
    ]
}, {
    locations: [
        [40.8304282, -73.9455893],
        [40.767693, -73.9962566],
        [40.7198128, -74.0012278]
    ]
}];

// Adds a route
map.addRoute(routesCollection[0]);

// Adds several routes
map.addRoute(routesCollection);

// Removes the route with specific configuration
map.removeRoute(routesCollection[0]);

// Removes the route with index 1 in the "routes" array
map.removeRoute(1);

// Removes the routes with specific configurations
map.removeRoute(routesCollection);

// Removes the routes with indexes 0 and 2 in the "routes" array
map.removeRoute([0, 2]);

To add or remove a route at runtime, bind the routes property of the Map to a component property.
