javascript geocoding from address to latitude,longitude - wordpress

Question

I m using google maps api v3. This is my code
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
<script src="https://maps.googleapis.com/maps/api/js?
v=3.exp&sensor=false&libraries=places"></script>
<script>
var geocoder;
var map;
function initialize() {
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input);
//var latlng = new google.maps.LatLng(18.52043030000, 73.85674369999);
var mapOptions = {
zoom: 15,
//center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('googleMap'), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
function codeAddress() {
var address = document.getElementById('searchTextField').value;
geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'searchTextField': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
alert(latitude);
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
</script>
I m doing all this in wordpress template file. I m displaying suggestion using autocmplete places. I want that when user select one of the location from suggestion list, map should navigate to that place. It's not going into the if condition i.e. if (status == google.maps.GeocoderStatus.OK) {
This is html code
<input id="searchTextField" type="textbox">
<input type="button" value="Geocode" onclick="codeAddress()">

If you run this code you will see you have an error that says:
InvalidValueError: unknown property searchTextField
Geocoder accepts 'address' as a property among others, but no 'searchTextField'.
So just change:
geocoder.geocode( { 'searchTextField': address}, function(results, status) {
to:
geocoder.geocode( { 'address': address}, function(results, status) {
