我有经纬度。我怎样才能得到西/东 | GPS的北/南？

附截图：截图

$().ready(function() {

    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    $('#location').geo_autocomplete(new google.maps.Geocoder, {

        $('#lng').val (_data.geometry.location.lng())


        console.log (coords.lat () + '/' + coords.lng ());

        if (_data) map.fitBounds(_data.geometry.viewport);
    });

});
</script>
<style>
.ac_results li img {
    float: left;
    margin-right: 5px;
}
</style>

东/西：如果经度 < 0 则为西，否则为东
北/南：如果纬度 < 0 则为南，否则为北

说明：
0 子午线（通过伦敦/格林威治）是东西方之间的界限。
赤道是南北之间的界限。

在 Google 中，坐标以十进制度数表示，其中负号定义 E/W 或 N/S
