About jQuery Cheat Sheet

This jQuery cheat sheet is a compact reference to the library that still powers a huge share of existing sites: selectors, document ready and DOM basics, DOM manipulation, attributes and CSS, events, effects and animation, traversing, AJAX, forms, and utilities.

If you maintain legacy front-ends, plugins or older CMS themes, jQuery fluency is still a practical skill. Each row pairs a method call with a one-line description, so you can recall the exact signature for event delegation, chained traversal or an AJAX request without digging through old documentation.

The sheet is free and fully client-side. Filter methods live with the search box, jump between sections from the sticky table of contents, copy any snippet with one click and print the page when you are deep in a legacy refactor.

How to use jQuery Cheat Sheet

Skim the sections, from Selectors and Document ready & DOM through Traversing to AJAX and Utilities.
Search for a method like on, closest or ajax to filter the sheet live.
Jump to a section such as Effects & animation via the sticky sidebar.
Click a snippet or its copy icon to copy the jQuery call into your code.
Print the sheet for offline reference while working on legacy projects.

Frequently asked questions

Ten sections: selectors, document ready and DOM basics, DOM manipulation, attributes and CSS, events, effects and animation, traversing, AJAX, forms, and utility helpers.

For new projects most teams use vanilla JavaScript, but an enormous amount of production code, plugins and CMS themes still run jQuery — this sheet is aimed at maintaining and migrating that code confidently.

Yes. The events section includes the delegated form of .on() along with binding, unbinding and triggering — the pattern you need most when working with dynamically inserted elements.

Yes. Click any snippet, or the copy icon on its row, and the call is copied to your clipboard ready to paste.

Yes, entirely free — searchable, printable and rendered in your browser with no sign-up.
