Answer 1

alert(results[1].address_component['country']); // country is a string

Answer 2

hi, this wont work alert(results[1].address_component['country']);

could this be a bug? or am i missing something? does results[1] includes the country name ?!

thanks

For one thing, address_components should be plural. The Google documentation is misleading on that due to a typo.

The address_components array has an item for each component of the address. The types array within each item tells you all of the types that apply to each address component (eg: country, locality, etc.) - So what you really want to do is find the address_components array item that has "country" as one of its types, and then take either the short_name or long_name for that array item.

Also, you may not always have a value for results[1]. That would assume there are at least 2 search results returned. results[0] would be the first one.

here's an example:

var country;

for (i=0;i<results[0].address_components.length;i++){
    for (j=0;j<results[0].address_components[i].types.length;j++){
       if(results[0].address_components[i].types[j]=="country")
          country = results[0].address_components[i].long_name
    }
}
