Based on a script written by Splarkaon Wikipedia, this code has been rewritten to use jQuery by Grunny and works in both Wikia and Monobook skins. A newer version was made by Ozuzanna that features more functionality than the original.
The option to use the Batch Delete script will appear under your "My Tools" list.
In order to delete a batch of pages, just add the page names (not page URLs) in the form, each on a new line, and proceed to delete 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 deleted.
Version 2 features the ability to protect the pages after deletion (this is optional), as well as loading from a modal on any page with the option to modify the rate at which it deletes/protects. If you'd like to modify the default rate of one delete every 1000 milliseconds (1 second), add the config batchDeleteDelay before importing the script with your own number (in milliseconds) instead. For example, using:
will lower the delete rate to 0.1 second.
This version also enables the user to grab a whole category's contents and puts them into the text area ready for deletion. Note that the script will only load if the user has access to the delete right (content moderator, administrator, VSTF, staff or helper). Deleting Message Walls and threads is possible, however, restoring them properly isn't possible.
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.
If you're already using importArticles(), you can import the script by adding the below to the article list. If you're not wanting to use the default rate of 1000ms, you need to add the config above the importArticles statement as shown in the installation.
