How can I know which radio button is selected via jQuery? I have two radio buttons and want to post the value of the selected one. How can I get the value with jQuery? I can get all of them like this: $("form :radio") How do I know which one is selected? Answer: To get the value of the selected radioName item of a form with id myForm: $('input[name=radioName]:checked', '#myForm').val() Here's an example: $('#myForm input').on('change', function() { alert($('input[name=radioName]:checked', '#myForm').val()); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form id="myForm"> <input type="radio" name="radioName"
