Want zoom level in Geocoder

[Bimal]

Hello
I am new to Google map. I am using this example to add Geocoder
feature in my site with Google Map
http://code.google.com/apis/maps/documentation/v3/examples/geocoding-simple.html

This is working fine but I want to add auto zoom feature for search
result.
Example, if I search for "China" then map displays it correctly but I
cannot get Zoom level dynamically. I am getting street view of China
but I want full map of china.
How can I do this ?

Thanks
- Bimal

Hi Bimal,

See this post:

The main method you need is Map .fitBounds()

Regards

And the geocoder response includes LatLngBounds

geometry.viewport and
geometry.bounds

which can be used with Map.fitBounds()

Thanks for fast reply

But this is not working
I have insterted the fitMap() function and call it in codeAddress()
function.

Please help me
Thanks

Can you provide a link to your page? Thats helps debugging.

Here is my page :
http://www.montotechnologies.com/geocode.html

I have added a dropdown box on top for Country selection. I am calling
a javascript function on select.

http://www.montotechnologies.com/geocode.html
fails when I press the "Geocode" button.

39: function codeAddress(country) {
40: //var address = document.getElementById("address").value;
41: var address = country.value;
42: if (geocoder) {
43: geocoder.geocode( { 'address': address}, function(results, status) {

On line 41 you write
var address = country.value;
country.value returns "Geocoder"

That's because you call codeAddress from the "Geocoder" button's
onclick handler:
<input type="button" value="Geocode" onclick="codeAddress(this)">

If instead I select an item from your drop-down menu, you geocode the
address correctly but then call fitMap without the address.:

24 function fitMap (map) {
25 var bounds = new google.maps.LatLngBounds();
26 map.fitBounds(bounds);
27 //map.set_zoom(map.getBoundsZoomLevel(bounds));
28 //map.set_zoom(map.getBoundsZoomLevel(bounds));
29 map.set_center(bounds.getCenter());
30
31}

Line 25 creates an empty LatLngBounds.
Line 26 fits the map to the empty LatLngBounds. That causes the map
to zoom out to level 0.

You will need to call map.fitBounds() with the LatLngBounds returned
by the Geocoder.
