Two radio buttons share one “id”?

Question

I\'m borrowing/adapting this simple html/javascript form set up to put some data in the database. The original code uses text fields in the form, but I\'m using radio button

Answer 1

If want to use pure javascript you have to use..

document.querySelector('input[name=radio_btn_name]');

but it need updated browser. Old browsers may result incorrect.

To overcome this issue, javascript library is to use (library will handle the issue). For this use the following..

$('input[name=radio_btn_name]:checked').val();
