How can I pass a value as an attribute from an Angular template to a directive?

Here's a directive I'm working with:

<g-map-locations center={{myLocation}} zoom="4" id="map" class="map"></g-map-locations>

The zoom parameter is used in Angular to set the zoom level for a Google Map:

attrs.zoom = zoom
setMapOptions: function(center, zoom){
    var mapOptions = {
    zoom: zoom,
    center: center
    }
    return mapOptions;
},

I'm running into an issue where Google Maps is throwing a setZoom: is not a number error, even though it seems to be functioning correctly.

zoom = 4

Is there a way for me to instruct Angular to pass the value as a number or somehow convert it within the directive?

Answer №1

When working with HTML attributes, they are typically passed as strings unless they are being passed in as scoped objects and then parsed accordingly. One simple approach would be to ensure that the number is properly parsed as an integer:

updateMapSettings: function(centerCoordinates, mapZoomLevel){
    var mapSettings = {
        zoom: parseInt(mapZoomLevel, 10),
        center: centerCoordinates
    }
    return mapSettings;
}
