How do you determine which radio is checked using Javascript, so I can change target on submit?

<form>
<input type=checkbox name=chk value=1>Send to 1
<input type=checkbox name=chk value=2>Send to 2
</form>

Good solution bustarooms but what if he has many?

for( i = 0; i < document.yourFormName.elements.length; i++ )
{
var found = false;

if( document.yourFormName.elements[i].type == "radio" && document.yourFormName.elements[i].checked )
{  
   alert( document.yourFormName.elements[i].name );
   found = true;
}

if( !found )
   alert("No Radio buttons were checked.");
