Question

I have the following function (taken from Elevation Service @ Google Maps API) which output for example 63.00425720214844 when I click somewhere on the map I have created with Google Maps JavaScript API v3:

function getElevation(event) {
    var locations = [];
    var clickedLocation = event.latLng;
    locations.push(clickedLocation);

    var positionalRequest = {
        'locations': locations
    }

    elevator.getElevationForLocations(positionalRequest, function(results, status) {
        if(status == google.maps.ElevationStatus.OK) {
            var s = results[0].elevation
            if(results[0]) {
                alert(s.substring(0, s.indexOf('.') - 1));
            } else {
                alert('Inget resultat hittades');
            }
        } else {
            alert('Det gick inte att hitta höjdskillnaden på grund av följande: ' + status);
        }
    });
}

I want to remove everything after the dot including the dot, for example remove .00425720214844 from 63.00425720214844 but when I click somewhere on the map, I’m getting this error message in the console: Uncaught TypeError: Object 63.00425720214844 has no method 'indexOf'.

What have I done wrong?

Thanks in advance.

Just do a javascript parseInt(63.00425720214844) to get 63.
