原文外掛簡介

Code Unloader is a free WordPress asset manager and script manager that lets you unload unused plugin CSS and JavaScript (JS) on selected pages without writing PHP. Unload assets where a page does not need them and keep them everywhere else. Reduce HTTP requests and page weight by loading files only where they are needed, which improves page speed and performance scores, with a one-click kill switch and per-request bypass for quick rollback.
One WordPress.org user unloaded eight JavaScript files and two CSS files from the homepage, reducing it by 634.2 KB and improving PageSpeed from 96 to 99. Results vary by site and depend on which assets can be safely unloaded.

Common uses

Unload contact-form CSS and JavaScript from pages without a form
Stop WooCommerce assets from loading on pages that do not use shop features
Unload slider, sharing, popup, or page-builder files where they are not needed
Unload JS and CSS only for mobile visitors, or only for desktop
Create different asset rules for desktop and mobile visitors
Apply rules to one URL, a group of URLs, post types, or conditional page types

How it works

Open any frontend page while logged in as an administrator.
Click ⚡ Assets in the WordPress Admin Toolbar.
Find a CSS or JavaScript file and switch it off.
Choose where the rule should apply: an exact URL, wildcard pattern, regular expression, device type, or condition.
Save the rule, clear page cache if needed, and test the page.

The frontend panel groups assets by plugin, theme, or WordPress Core, making it easier to see what is loading and where it came from.

Unload assets per page: scripts, styles and plugin files
WordPress registers each script and stylesheet by handle, and most plugins enqueue theirs on every page. Code Unloader dequeues those handles on the pages you choose, so a form script, slider stylesheet or page-builder bundle loads only where it is used. It works on registered files from plugins, themes and WordPress core alike, and shows you the file’s source before you unload it.
