Description
editEdit a page on a foreign wiki. Could easily be modified for other types of actions.
Code

* CORS cross-site editing example

// Custom hooks for edit success / failure (e.g., console.log)
var errorHook = typeof info.error === 'function', // has error function?

// Most "modern" browsers except IE support CORS
if (!$.support.cors) {
