What is the method for notifying the latitude within this Google Maps javascript code?

There's a specific line that triggers an alert showing "undefined". However, when I just alert results[0].geometry.location, it displays (41.321, 41.556).

My goal is to alert this value and then convert it (as an integer) to my id_lat and id_longs...


$("#geocodesubmit").click(function(){
        $("#id_lat").val("");
        $("#id_long").val("");
        var address = $("#addressinput").val();
        geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            $("#badlocation_holder").hide();
            $("#map_canvas").show();
            $("#map_canvas_holder").show().css("background-color", "#E6E6FA").animate({"background-color":"#f5f5f5"}, 800);
            ;
            var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);  
            map.setCenter(results[0].geometry.location);

            alert(results[0].geometry.location[1]); //this is undefined.

            $("#id_lat").val(results[0].geometry.location[0]);
            $("#id_long").val(results[0].geometry.location[1]);


            var marker = new google.maps.Marker({
                map: map, 
                position: results[0].geometry.location,
                draggable:true
            });
          } else {
              $("#map_canvas_holder").hide();
              $("#badlocation_holder").show().css("background-color","#F08080").animate(
              {"background-color":"#f5f5f5"},800);
          }
        });
        return false;
    });

Answer №1

Retrieve the latitude with

results[0].geometry.location.lat()
and obtain the longitude using
results[0].geometry.location.lng()
.

Answer №2

When utilizing the API, the key detail to note is that location is not an array, but a property. Therefore, accessing it with .location is the correct approach, rather than using .location[0].

Locating accurate information in the official documentation can be challenging for certain types, however, you can find updated resources on location (specifically a LatLng type) here:

The method toString() will display the alert as (lat, long), and additionally there are functions like .lat() for latitude and .lng() for longitude, shown here:

alert(results[0].geometry.location.lat());
alert(results[0].geometry.location.lng());
