Quick Reference
The data() method attaches data to, or gets data from, a selected element.
$('div').data();Syntax
To Attach Data to an Element:
(selector).data(name,value)$('button').click(function() {
alert($('div').data('message', 'Hello World'));
});To Get Data from an Element:
(selector).data(name)$('button').click(function() {
alert($('div').data('message'));
});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.
Parameters

- When using jQuery, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
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.
