MassNullEdit is based on several other scripts (NullEditButton, AjaxBatchDelete and ChatBlockButton) that provides a link to a modal (without changing location) which allows the user to list pages to be null edited.


In order to null edit multiple pages, add the page names (not page URLs) each on a new line (including their namespace if necessary) and proceed to null edit them. The script will stop when it reaches an empty line.

If the script is used on Special:WhatLinksHere, it will automatically add the listed pages/files into the text area. Users may also add the contents of categories straight into the text area using the button.

By default, the script will do one page per second. If you'd like to modify that, add the config nullEditDelay before importing the script with your own number (in milliseconds) instead.


The option to use the Mass Null Edit script will appear in your toolbox on the left.


The option to use the Mass Null Edit script will appear under your "My Tools" list (the toolbar at the bottom of your screen).

Please note you must not have the toolbar at the bottom hidden or the script will not function. If you do not see the "My Tools" (or other language equivalent), try clicking Customize and then "reset defaults" to not hide the "My Tools".



Add this JavaScript on your wiki:

Global Personal
w:Special:Mypage/global.js Special:Mypage/common.js
nullEditDelay = 1000;
importScriptPage('MediaWiki:MassNullEdit/code.js', 'dev');
importArticles — Best Practices for installing JavaScript on FANDOM
The importArticles statement is designed to combine multiple HTTP requests into a single data transfer, allowing multiple scripts to load and execute faster. If you've been installing several different scripts, your JavaScript file has probably accumulated unnecessary import statements. Click "Expand" to learn how to efficiently batch import scripts to speed up performance and make your code look cleaner. One other approach is by using the MediaWiki:ImportJS.
If your JavaScript file has several lines of code that say importScript, importScriptPage, or importArticles, you may be able to combine them! By batch importing a collection of scripts with a single import, your JavaScript code will load faster and look cleaner. Consider the example below. On the left is an example of what your JavaScript file might currently look like. On the right is how you could improve that code.
Multiple imports — messy and slow One import — clean and efficient
  type: 'script',
  article: 'u:dev:FloatingToc/code.js'
importScriptPage('page1.js', 'wikiname');
importScriptPage('page2.js', 'wikiname');
    type: 'script',
    articles: [
Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.
But there's much more to importArticles than just this! For more examples and advanced usage, see the help page at Help:Including additional JavaScript and CSS.

If you would like another button to access this script while using Special:WhatLinksHere for the autocomplete functionality but are unable to load it from that point, you can add the following config above the import statement to have this as well. It will appear in the user drop-down menu in the top right.

nullEditUserButton = true;
