Question

How to use jQuery to get the checked checkboxes values, and put it into a textarea immediately?

Just like this code:

Answer 1

Anyway, you probably need something like this:

 var val = $('#c_b :checkbox').is(':checked').val();
 $('#t').val( val );

This will get the value of the first checked checkbox on the page and insert that in the textarea with id='textarea'.

Note that in your example code you should put the checkboxes in a form.
