var checkSelected = false;
for (i = 0; i < planForm.locationOptions.length; i++) {
if (planForm.locationOptions[i].checked) {
checkSelected = true
document.planForm.action=’refreshPlanView.do’;document.planForm.submit();
document.getElementById(“refreshing”).style.display=”block”;
}
}
if (!checkSelected) {
alert(“At least ONE Location must be selected!”);
return false;
}
return true;
}
