Hi,

I want to use a form select-field for users to select their country of residence, which shows the IP based country as default value (plus the IP address next to it);

Location info (ipinfodb.com) is working. I'm passing "country" and "ip" to the function, which should modify select-field and ip adress

Problem: IP adress works, but the select-field only updates after I hit refresh.

Can someone tell me why?

Here is the code:
HTML

<select name="setup_changeCountry" id="setup_changeCountry">
     <option value="AL-Albania">Albanien</option>
     <option value="AD-Andorra">Andorra</option>
     <option value="AM-Armenia">Armenien</option>
     <option value="AU-Australia">Australien</option>
     ...
</select>
<div class="setup_IPInfo">
    <span>Your IP</span>
    <span class="ipAdress"> -- ip --</span>
</div>

Javascript/Jquery

function morph(country,ip) >> passed from function, called on DOMContentLoaded
{
var ipAdress = ip;
$('.ipAdress').text(ipAdress);

var countryForm = country; 
$('#setup_changeCountry  option').each(function()
    {
    if ($(this).val().substr(0,2) == countryForm)
        {
        $(this).attr('selected', "true");
        }
    });
} 

Thanks for any clues on how to fix this.
