Custom JavaScript for Websites 2 - Chrome Extension

Run custom JavaScript on any website. Use this tool to inject custom javascript in any website.

Your scripts are kept in the local storage and applied across domain URLs.

You can use jQuery 1.11.x or 2.1.x or your own external scripts.

Use cases:

  • site debugging (wrong list sort, etc.)
  • hiding annoyng popups and Ads
  • custom UI
  • anything you can think of :)

New features:

  • Ace Editor (formating, highlight, undo/redo by hotkeys)
  • Draft auto save (so doesn't matter when you close the window without saving)
  • Hosts (websites) switch (you can browse customjs of other websites)
  • Include external script (eq. Underscore.js is cool)

Thanks to:


You can find base.js at extension/lib/base.js. It provides useful functions for you. You can directly use all functions in your JavaScript code. To avoid name conflict, all functions start with customjs.

Now there're only one function:


customjsReady('.nav', function(element) {
  // do something

The customjsReady wiil be called when an element matching the selector is added to the DOM. You can find more details from:
