This article is about a system or feature that is no longer in use.

The page is retained for historical reasons.

Reason: Code pages use the Ace editor by default as of March 6th, 2019.

This script is for PERSONAL use only!

You are free to install this script for yourself, but it is not allowed to be used wiki-wide (e.g., in MediaWiki:Common.js or MediaWiki:Wikia.js), as it would violate Fandom's Terms of Use.
(See the customization policy)

CodeEditorSwitch is a script that allows the user to use the VisualEditor for regular pages and the Classic editor for code pages. It modifies the "Edit" button on pages ending in .js and .css to use the Classic editor and redirects .js and .css VisualEditor links to the Classic editor.


Option List & Defaults

The following tables lists all the options that can be configured, a description of each, their accepted values, and their default values.

Option Description Accepted Values Default
changeEditBtn Whether or not to change the "Edit" button on .js and .css pages to use the Classic editor. true, false true
redirectToClassic Whether or not to redirect .js and .css VisualEditor links to the Classic editor. true, false true
lang Defines which language the script should use to display the "VisualEditor" text in the edit menu. Two letter language codes as a string (i.e. surrounded in quotes) Language set in the user's preferences or "en" if that language is not supported

How to Configure

To configure CodeEditorSwitch properties, use the window.codeEditorSwitch object and place it before the importArticles call in your personal JavaScript. Be sure to separate each the properties with a comma. An example configuration follows:

window.codeEditorSwitch = {
// importArticles call
    type: 'script',
    articles: [
        // ...

Using configuration options with Fandom Developers Wiki scripts

The instructions on this page describe how to use configuration options with a script. Here on the Fandom Developers Wiki, many scripts provide optional configuration settings as a mean to alter or enhance the default behavior of the script. When installing configuration options in your JavaScript file, please note that they need to go above the import statement in order to work — unless the directions say otherwise. In case MediaWiki:ImportJS is used to load the scripts, it will be executed last.

Configuration options load too late, don't work
// 1. AjaxRC import statement
// 2. AjaxRC configuration option
var ajaxRefresh = 30000;
Proper placement of configuration options
// 1. AjaxRC configuration option
var ajaxRefresh = 30000;
// 2. AjaxRC import statement


  • When redirectToClassic is set to true, the VisualEditor link in the "Edit" menu is not redirected. This is done with the cesredirect=false URL parameter.
    • You can force users with CodeEditorSwitch installed to use the VisualEditor for a .js or .css link by adding &cesredirect=false after ?veaction=edit. However, this is not recommended because those users prefer the Classic editor for code, unless you are trying to demonstrate a bug with the VisualEditor.

Submitting Translations

If you would like to submit a translation for CodeEditorSwitch, you can do so on the code.js page in the i18n object. Please place translations in alphabetical order according to the language's two-letter code (e.g. "en" is "English"), and use the translation Fandom uses for the "VisualEditor" button in the "Edit" menu. Using a different translation can be inconsistent and confusing for a user, as they may be used to seeing certain text. If Fandom uses the text "VisualEditor" for the VE button for a language, please do not submit that translation as the script labels the button "VisualEditor" by default.
