On the off chance that you as of now have a reference to a radio catch bunch, for instance:
***var myRadio = $("input[name=myRadio]");***
Utilize the **filter()** fucntion, not **find()**. **(find()** is for finding kid/relative components, while **filter()** look through high level components in your determination.)
***var checkedValue = myRadio.filter(":checked").val();***
This answer was initially remedying another answer that suggested utilizing **find()**, which appears to have since been changed. **find()** could, in any case, be valuable for the circumstance where you previously had a reference to a compartment component, however not to the radio catches, e.g.:
***var form = $("#mainForm");
...
var checkedValue = form.find("input[name=myRadio]:checked").val();***
