Yuku: Post Saver

// Yuku: Post Saver // Copyright (c) 2006-2007 Orbona // Version 1.0 // Release Date: 2007-10-22 // // See also: http://www.orbona.com/greasemonkey/ // // Original file name: yuku_postsaver.user.js // Please reference the original file name when contacting me regarding this // script. // // This software is licensed under the CC-GNU GPL: // http://creativecommons.org/license/cc-gpl // //----------------------------------------------------------------------------- // DESCRIPTION // // This script modifies the page so that posts are automatically copied to // the system clipboard or to Greasemonkey storage when a post is submitted. // Since the "copy" is performed before the page unloads, posts will never // be lost again (well, unless changes to the site or to Greasemonkey break // this script). This is quite handy, because on some message boards, // returning to the "add/edit post form" doesn't always show you a cached // version of what was typed. When this script is used, if a "submit" // doesn't complete properly, a "Paste" or Tools >> Greasemonkey >> // User Script Commands will give you back your post. // // WARNING: (1) When you submit a post, any text already on the system // clipboard will be overwritten. // // (2) Obviously, a subsequent "cut" or "copy" will overwrite the // post data on the system clipboard, so it's a good idea to // see if your post got "eaten" before doing any more text // editing in any application. //----------------------------------------------------------------------------- // ==UserScript== // @name Yuku: Post Saver // @description Automatically copies posts when submitting // @namespace http://www.orbona.com/greasemonkey/ // @include http://*.yuku.com/forum/* // @include http://*.yuku.com/topic/* // ==/UserScript== //----------------------------------------------------------------------------- // A wrapper for the main "copyPostToClipboard" method added to the main // document.

If the user is currently // saving to the system clipboard, then the most recently edited post won't // be here. Selecting 'ok' on the prompt window will NOT paste the last post // contents into the post body text box since Yuku uses a fancy HTML editor // and I haven't had time to figure out a fool-proof way to set the inner // HTML for the editor.
