Quick Reference
The on() method attaches one or more event handlers to the selected elements and child elements.
$('div').on('click', function() {
alert('The element was clicked.');
});
Syntax
$(selector).on(event,childSelector,data,function,map)
Note
It is generally good practice to place your jQuery code/function inside the document load function so that the action takes place ONLY after the document has finished loading. This ensures that all of the page elements that you may be selecting are in place before running the code on them.

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
