I m developing one application in which i m having the address of particular person, now i want to find the location of that person on google map. I want to save the latitude and longitude of that person when i m saving his details. How can i find the latitude and longitude from the address?

In address, i m saving his city, state , country, street, etc.

The thing you want to do is called geocoding, see the page on Google Geocoding API

Update:

Probably you will need this function. It is able to iterate over an array and execute a callback after each geocoding return:

function locate(address, callback) {
    var geocoder = new google.maps.Geocoder(),
        latlong = [];

    geocoder.geocode({
        address: address[0]
    }, function(results, status) {
        if (status === google.maps.GeocoderStatus.OK) {
            latlong.push([results[0].geometry.location.Ma, results[0].geometry.location.Na]);
            address.shift();
            if (typeof callback === 'function') callback(latlong);

            if (address.length === 0) {
                return;
            } else {
                locate(address, callback);
            }
        }
    });
}


/*
 * Sample use
 */
locate(['1 Infinite Loop, Cupertino, CA', '1600 Amphitheatre Parkway, Mountain View, CA'], function(result) {
    console.log(result);
});

Don’t forget to include Google Maps API JS file before your script.

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
