How can I know which radio button is selected via jQuery?

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();

This should work:

$("input[name='radioName']:checked").val()
Note the "" usaged around the input:checked and not '' like the Peter J's solution

To get the value of the selected radio name item with a form id my form

$('input[name=radioName]:checked', '#myForm').val()
