Solving Issues with Google Maps Javascript API v3

My code doesn't seem to be functioning properly. Instead of displaying an error message, it's just showing a blank screen. Could you please take a look at my code to identify the issue? Thank you.

Answer №1

The settings variable lacks a closing bracket and is not within the same scope as the global call to instantiate the map. Even if it were, the map variable instantiation would occur prior to the initialize() function being called. To rectify this, you can use the following snippet of code:

<script type="text/javascript">
    var map;
    function initialize() {
        var latlng = new google.maps.LatLng(57.0442, 9.9116);
        var settings = {
            zoom: 15,
            center: latlng,
            mapTypeControl: true,
            mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
            navigationControl: true,
            navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        map = new google.maps.Map(document.getElementById("map_canvas"), settings);
    };

</script>
