Easily by calling parent.your_var_name in your iframe's script.

One condition: both pages (main and iframe's) have to be on the same domain.

main page:

<script>

 var my_var = 'hello world!';

</script>

iframe

<script>

  function some_fn(){

    alert(parent.my_var); //helo world!

  }

</script>
