Var item = $(' input [@ name = items] [@ checked] '). The val ();

The second element of the radio radio group is the currently selected value

$(' input [@ name = items] '). The get (1) checked = true

Radio set radio: $(" input [@ type = radio] "). The attr (" checked ", '2'); // the item with value=2 is the currently selected item

The old version of jquery

Var_name = $(" input [@ name = 'radio_name'] : checked "). The val ();

Jquery 1.3 later

Var_name = $(" input [name = 'radio_name'] : checked "). The val ();

var_name = $("input[name='isspecialcnt']:checked").val();
//alert(var_name);
if(var_name=='1'){
$("#isspecialcntyes").show();
$("#isspecialcntno").hide();
}
if(var_name=='0'){
$("#isspecialcntyes").hide();
