The old version of jquery
Var_name = $ ("input[@name = ' radio_name ']:checked"). Val ();

Look at a jquery instance that gets the radio value

function Getra () {

Var_name = $ ("input[name= ' isspecialcnt ']:checked"). Val ();
alert (var_name);
if (var_name== ' 1 ') {
$ ("#isspecialcntyes"). Show ();
$ ("#isspecialcntno"). Hide ();
}
if (var_name== ' 0 ') {
$ ("#isspecialcntyes"). Hide ();
$ ("#isspecialcntno"). Show ();
}
}
