Based on a script written by Splarka on Wikipedia and rewritten to use jQuery by Grunny, this script works in both Wikia and Monobook skins. It provides a link to a batch undelete form that allows you to list pages to be undeleted, through the API. This script is, essentially, the opposite to AjaxBatchDelete and functions similarly. Nerfmaster8 and Noreplyz have updated the script to using the second version of AjaxBatchDelete.

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

importScriptPage('page1.js', 'wikiname');
importScriptPage('page2.js', 'wikiname');
    type: 'script',

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.


The option to use the Batch Undelete script will appear under your "My Tools" list in oasis and in the toolbar for monobook. In order to undelete a batch of pages, just add the page names (not page URLs) in the form, each on a new line, and proceed to undelete them with a set reason. The script will stop when it reaches an empty line, and it can be terminated early by blanking the list of pages remaining to be undeleted.
