If you're looking to streamline a task on your website, utilizing the jQuery library can be extremely beneficial. While it's possible to achieve the same outcome without jQuery, incorporating it into your workflow can simplify the process significantly.
For instance, consider the following example that mirrors a snippet I frequently employ in my own projects. In this scenario, Script.php represents the server-side script, original.gif pertains to an image displayed on your webpage, and loading.gif serves as the animated 'loading bar' visual.
To implement this code snippet, ensure that you have included the jQuery library within your page.
$(document).ready(function() {
$('#gifImage').click(gifImage_click);
// Here, gifImage corresponds to the ID of the image you wish to swap with a loading gif.
});
function gifImage_click() {
// This code snippet replaces the initial gif image with the loading animation.
$('#gifImage').attr('src','loading.gif');
function successFunction(response) {
// Executed upon successful script execution.
$('#gifImage').attr('src','original.gif');
alert('script completed successfully');
}
function errorFunction(xhr) {
// Triggered if the script encounters an error during execution.
$('#gifImage').attr('src','original.gif');
alert('script execution failed');
}
$.ajax({
type: "POST",
url: "Script.php",
success: successFunction,
error: errorFunction
}); // end - $.ajax
}
