Do something when radio button is checked jQuery?

We have to add an event listener and some attributes to the HTML element whose value is checked when it's checked.  To avoid the mouseover event is called when the radio button is checked, simply use the same jQuery event for both the unchecked and checked states, as follows:

jQuery check a radio button

on Jan 01, 1970
// jQuery version 1.6 or above use:  
$("#myRadioID").prop("checked", true);
 
//jQuery versions below 1.6 use:
$("#myRadioID").attr('checked', 'checked');

There are three user actions that jQuery can run your code when they occur, mouseover, blur, and one click. You can learn more about jQuery event handling here.
