Control the loading of JS and CSS files globally and specifically in Joomla!

With this plugin, the loading of JS and CSS files can be easily controlled. You may suppress loading those files on pages where they are not needed. This might be important for example at the frontpage for optimizing loading times. The plugin is able to exclude those files globally or just on selected pages.

For global exclusion you have to enter the concerned file (with suffix) in a field. For selective exclusion on specified pages you have to enter parameters of the specified page additionally to the file name. You may generate an output of required parameters using the Debug Mode in the frontend. See "Installation" for more details.

Features

Excludes / Includes JavaScript (.js) files
Adds async and defer attributes to the script tags
Excludes / Includes CSS (.css) files
Global and specific deactivation of the files
Debug Mode (for determining of the required parameters) with detailed information

Language: English and German

Installation

Install the plugin by accessing the administration menu of the back-end under Extensions. Then access Extensions -> Plugins -> System - JCC - JS CSS Control and customize it to your needs. Don't forget to activate the plugin eventually!

Usage:

There are two options available. The first one is for the exclusion of JavaScript files, the second for the CSS files.

Enter only one file name each line. If you want to disable the file globally on all sides, then it is sufficient to enter the name of the file with the .js / .css extension. If you want to exclude specific files on a particular page, then you must also specify the parameters of the page. The parameters can be determined using the option "Debug Mode".

Procedure: Enable debug mode, load the desired page in the frontend, copy and paste the displayed parameters in the plugin settings, disable debug mode.

Debug Mode:

The debug mode shows the parameters with which the files can be excluded on certain pages. In addition, further information such as the number and sizes of files are displayed.

Version 5.2.0.0-PRO - 2025-01-13

+ Increased technical requirements for Joomla! 5: Increasing Technical Requirements 2025 - Core & PHP for Joomla! Pro Extensions
+ Optimising code to meet new requirements can enhance its quality, performance, and security.

Version 5.1.0.0-PRO - 2024-05-27

+ Subscriber Interface: The plugin has been rewritten to utilise the subscriber interface, enhancing its integration and performance capabilities.
+ Improved Pro Security Token validation check. The Pro package contains a token file with an individual security token linked to the user account that is checked against the validation server for authenticity. If the file is missing or the token is invalid, you cannot edit the settings and use the extension. The Pro Security Token field has been extended to handle incorrect tokens and blocked accounts. If you encounter an error message related to the token, download the Pro version with your Pro subscription from the linked download page and install it again!
Attention: The Pro extension will not work correctly if the token file or custom field is missing or modified. Never edit or remove the files to ensure correct functionality.

Version 5.0.2.0-PRO - 2024-03-12

+ Added Execution type option for JavaScript rules. You may select the type of execution for the rule. The async and defer attributes in the <script> tag optimise JavaScript loading in HTML documents. async allows a script to load in the background and execute immediately upon download, ideal for independent scripts. defer also loads scripts in the background but delays execution until the HTML document is fully parsed, suitable for scripts that interact with the DOM or depend on other scripts. These attributes enhance page load performance by controlling script execution timing. The default value is remove. Thanks to Tanja for requesting this feature!
