Re: [Flashcoders] Question on variable init in a for loop

[allandt bik-elliott (thefieldcomic.com)]

no that's correct but id should be declared outside of your loop - as3 will
actually give you a duplicate variable error for putting it inside the loop.

you can also refer to your iterator (i) after the loop is done

i'd rewrite your function like this

var arObj:Array = [{},{}]
function test():void
{
      var id:String;

       for each(var i:Object in arObj)
       {
               trace("1" ,id);
               id = "test" + Number(Math.random()).toString();
               trace("2" ,id);
       }

       trace(i);
}
