how to get jquery on() to work on not-yet-existing elements
<p>I have always used delegate() to bind events to elements which don't exist when the DOM is initially loaded. I understand that on() is supposed to replace delegate, but I don't understand the documentation on the jquery site how exactly I would translate the following code to use with on()</p>

<pre><code>$(document).delegate(
            ".Course_Name, .Start_Date, .Book_Title, .Book_Author, .Book_Isbn",
                "click",
                function()
                {
                    var whichButton = $(this).attr("class");
                    make_table(whichButton);
                    fillISBN();
                });
</code></pre>
