This is quite handy, because on TWoP, 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 IP.Board: Post Saver // @description Automatically copies posts when submitting // @namespace http://www.orbona.com/greasemonkey/ // @include http://forums.televisionwithoutpity.com/index.php* // @include http://www2.konfabulator.com/forums/index.php* // ==/UserScript== var postContentIDName = 'ed-0_textarea'; var gotEditor = true; //----------------------------------------------------------------------------- // A wrapper for the main "copyPostToClipboard" method added to the main // document.
