Trabaja con marcadores

Desarrolladores del Espacio Económico Europeo (EEE)

Llama a createWaypointAdvancedMarkers() para crear marcadores para los puntos de referencia de la ruta. De forma predeterminada, createWaypointAdvancedMarkers() crea marcadores para la ruta etiquetada como "A", "B", "C", etcétera, para cada punto de referencia. Puedes personalizar aún más los marcadores pasando opciones para modificar el diseño del marcador según el índice o las propiedades del RouteLeg correspondiente.

En el siguiente ejemplo de código, se muestra cómo crear marcadores personalizados para las paradas de la ruta.

Cómo agregar marcadores predeterminados

Para agregar marcadores con el diseño predeterminado, llama a createWaypointAdvancedMarkers() y pasa una opción de marcador para especificar el mapa actual, como se muestra en el siguiente fragmento de código. 

// Create markers using default style.
const markers = await result.routes[0].createWaypointAdvancedMarkers({ map: innerMap });

Agrega marcadores con un diseño personalizado

Para agregar marcadores con un diseño personalizado, llama a createWaypointAdvancedMarkers() y pasa opciones de marcador que incluyan propiedades de diseño personalizadas. Cuando aplicas estilos como este, todos los marcadores se diseñan de la misma manera. En el siguiente fragmento de código, se muestra cómo crear marcadores con un diseño personalizado. 

// Create markers with a custom style.
const markerOptions = {
  map: innerMap,
  content: new PinElement({
    scale: 1.5,
    background: '#8C0DD1',
    borderColor: '#6D0AA5',
    glyphColor: '#6D0AA5',
  }).element
}

const markers = await result.routes[0].createWaypointAdvancedMarkers(markerOptions);

Aplica un diseño personalizado a marcadores individuales

Para aplicar un diseño personalizado a marcadores individuales, pasa una función a createWaypointAdvancedMarkers() para establecer opciones de diseño de marcadores según el índice del marcador o las propiedades de RouteLeg. En el siguiente fragmento de código, se muestra una función para crear marcadores y darles un diseño según el índice del marcador:

TypeScript

// Alter style based on marker index.

        glyphColor: 'white',
        background: 'green',
        borderColor: 'green',
      }).element
    }
