I can set a radio button to checked fine, but what I want to do is set up a sort of 'listener' that activates when a certain radio button is checked.

Take, for example, the following code:


    $('#radio_button').attr("checked", "checked");


it adds a checked attribute and all is well, but how would I go about adding an alert. For example, that pops up when the radio button is checked without the help of the click function?

Try using the code given below:

$('#element').click(function() {

   if($('#radio_button').is(':checked')) { alert("it's checked"); }
