I am using google map in my website, bydefault it takes latitude and longitude to display center area during intializing the map. I have latitude, longitude and pincode variable, so i want when my latitude and longitude have values then it show on map during initializing but when they are empty display my pincode as center on the map.
var lat = '<%=lat%>';
var lon = '<%=lon%>';
var pincode = '<%=mappincode%>';

function first() 
             if (!lat || !lon) {
                 geocoder.geocode({ 'address': pincode }, function (results, status) {
                     if (status == google.maps.GeocoderStatus.OK) {
                         lat = results[0];
                         lon = results[0].geometry.location.lng();
             } else {

function InitializeMap() {
         var latlng = new google.maps.LatLng(lat, lon);
         var myOptions =
             zoom: 13,
             center: latlng,
             mapTypeId: google.maps.MapTypeId.ROADMAP
         var map = new google.maps.Map(document.getElementById("Gmap"), myOptions);
window.onload = first;

<div id ="Gmap" style="height: 300px; width: 600px; removed 25px; removed 25px;" ></div>
