You have asked this code:
$('p').html('<br/>Selected Radio Button Value is : ' + selValue + '');
to display the selected value of the radio button inside any
<p>
tag. But you have not provided any
<p></p>
for it to display, add it to your HTML. BTW, you are using HTML5, there is no need to have
/
in ending any HTML tags, for example, instead of
<br />
, just
<br>
will do.
