Quick Reference
The .ajaxSetup() method sets default values for future AJAX requests.
<!-- html element to place output -->
<p id="my_output"></p>
// on button click get some info and if successful place it in the HTML element
$('button').click(function() {
$.ajaxSetup({
url: 'test.txt',
success: function(result) {
$('#my_output').html(result);
}
});
$.ajax();
});
Syntax
$.ajaxSetup({name:value, name:value, ... })
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.

- To use jQuery on your site, it must first be downloaded from the official jQuery site and linked to in your document
head, or linked to via a CDN in your documenthead - 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
- When using jQuery, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
