Js unchecks the radio button and determines whether the object is empty

The name of a set of radio buttons is country

 
var country = document.getElementsByName('country'); 
for(var i=0;i<country.length;i++){ 
if(country[i].checked) 
{ 
country[i].checked=false; //Not selected
} 
} 

<c:if test="${shippingAddressList != null && not empty shippingAddressList}"> //Determines whether the collection shippingAddressList is empty
