I am trying to geocode an address given by the user in the text field, however my JavaScript function does not execute from the line \"geocoder.geocode ({\'address\':address......\" onwards.

I am trying to geocode an address given by the user in the text field, however my JavaScript function does not execute from the line "geocoder.geocode ({'address':address......" onwards.

I am stuck here not sure why it doesn't work. It throws thee first alert box showing the address field pulled over to the client script but does not work after that. It just stays without any action. Please let me know where i need to correct. Here is the client side code.

var map;
var geocoder;
function initialize()
{
    geocoder = new google.maps.Geocoder();  
}
function getgeocode() {  
    var address = document.advpollsrch.txtaddress.value;
    alert(address);
    geocoder.geocode( {'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            alert("Geocode was successful");
            var latlng = results[0].geometry.location;
            document.advpollsrch.hidlatitude.value = latlng.lat();
            document.advpollsrch.hidlongitude.value = latlng.lng();
            alert("Geocode split was successful");
            return true;
        } else {
            alert("Geocode was not successful for the following reason: " + status);
            return false;
        }
    });
}  
<body onload="initialize()">
    <form  name="advpollsrch"> <!-- onsubmit="return getgeocode()" -->
        <input type="hidden" name="hidlatitude" id="hidlatitude"></input>
        <input type="hidden" name="hidlongitude" id="hidlongitude"></input>
