Domain switcher button for different languages - if-statement

Question

I want to create a dropdown menu With English or German as the options in Javascript / jQuery that checks that:
check if on a domain - say happy.com/pizza
if german is selected on dropdown
redirect user to
happy.de/pizza
and I could have a list
if happy.com/pizza got to happy.de/pizza
happy.com/coke got to happy.de/coke
happy.com/juice got to happy.de/juice
etc etc.
I have written the code yet but how would one go about this?
Thanks!
I have written some code but I just need a little help please:
In this scenario I am on the www.something.com/beer page and want it to go to the German Beer Page!
<select>
<option value="1">English</option>
<option value="2">German</option>
</select>
if(value == 2) && is current domain www.something.com/beer{
window.top.location.href = 'www.something.de/beer';
}else if(value == 2) && is current domain www.something.com/cheese{
window.top.location.href = 'www.something.de/cheese';
}else{
do nothing
}
How do I get this to check the value of the dropdown and the domain is currently on?
Here is my Jsfiddle

function current(arr) {
// discuss at: http://phpjs.org/functions/current/
// original by: Brett Zamir (http://brett-zamir.me)
// note: Uses global: php_js to store the array pointer
// example 1: transport = ['foot', 'bike', 'car', 'plane'];
// example 1: current(transport);
// returns 1: 'foot'
this.php_js = this.php_js || {};
this.php_js.pointers = this.php_js.pointers || [];
var indexOf = function (value) {
for (var i = 0, length = this.length; i < length; i++) {
if (this[i] === value) {
return i;
}
}
return -1;
};
// END REDUNDANT
var pointers = this.php_js.pointers;
if (!pointers.indexOf) {
pointers.indexOf = indexOf;
}
if (pointers.indexOf(arr) === -1) {
pointers.push(arr, 0);
}
var arrpos = pointers.indexOf(arr);
var cursor = pointers[arrpos + 1];
if (Object.prototype.toString.call(arr) === '[object Array]') {
return arr[cursor] || false;
}
var ct = 0;
for (var k in arr) {
if (ct === cursor) {
return arr[k];
}
ct++;
}
// Empty
return false;
