Mootools set radio button checked

Question

I have 2 radio buttons

and I used mootool while loading as

 window.addEvent('domready', function() {
   var chk="1";
 if(chk==1){

$('edit-gender-0').set('checked',true);
 }

else if(chk==2){
 $('edit-gender-1').set('checked',true);

  }

but it is not working at all.

Any help will be appreciated... and any other short solution without the if-condition.

Answer 1

The code you've provided works just fine - here's a test-case: http://jsfiddle.net/oskar/tM29a/

Answer 2

window.addEvent('domready', function() {
   var chk="1";
   if(chk==1){
      $('edit-gender-0').set('checked',true);
   } else if(chk==2){
      $('edit-gender-1').set('checked',true);
});

don't forget to add }); at the end of the addEvent function.
