How to get the selected value of the radio button list in jquery?

Question

I have radio button list which has id as the value, I want to access the selected id in the jquery function.

Answer 1

If you have HTML that looks like this:

<input type='radio' name='choices' value='1'>
<input type='radio' name='choices' value='2'>
<input type='radio' name='choices' value='3'>
<input type='radio' name='choices' value='4'>
<input type='radio' name='choices' value='5'>

You would get the selected radio value with this:

$("input:radio[name='choices']:checked").val();

Answer 2

It will get the selected value of the radiobutton at button click.
ex for list

$("#btn").click(function() {
   $('input[type="radio"]:checked').val();
});
