How to check loaded jQuery UI version?

In this post I will show how to check currently loaded jQuery UI version on the page. Unlike checking loaded jQuery version ( $().jquery ), checking jQuery UI version is a bit different.

Checking currently loaded jQuery UI version on the page:

// Returns jQuery UI version (ex: 1.8.2) or undefined $.ui.version // Alternatively jQuery.ui.version

You would most probably use it in the if statement:

if($.ui && $.ui.version){ // jQuery UI is loaded }

// Checking if jQuery UI is loaded or not if($.ui){ // jQuery UI is loaded }else { // jQuery UI is not loaded }
