Getting the checked radio button when there's only one
If I only have one radio button, JS decides it ain't a list and won't give you a length for it, so you have to trap for this:
limit = document.forms[1].customer_id.length;
if(limit){ for(i = 0; i < limit; i++){
if(document.forms[1].customer_id[i].checked == true){
this_id = document.forms[1].customer_id[i].value; }
}
}
else { this_id = document.forms[1].customer_id.value; }
window.opener.document.location='index.php?customer_id=' + this_id;
window.close();
