SunEditor

Compose beautifully formatted text in your web application. Trix is an editor for writing messages, comments, articles, and lists, the simple documents most web apps are made of. It features a sophisticated document model, support for embedded attachments, and outputs terse and consistent HTML. Most WYSIWYG editors are wrappers around HTML’s contenteditable and execCommand APIs, designed by Microsoft to support live editing of web pages in Internet Explorer 5.5, and eventually reverse-engineered and copied by other browsers. Because these APIs were never fully specified or documented, and because WYSIWYG HTML editors are enormous in scope, each browser’s implementation has its own set of bugs and quirks, and JavaScript developers are left to resolve the inconsistencies. Trix sidesteps these inconsistencies by treating contenteditable as an I/O device: when input makes its way to the editor, Trix converts that input into an editing operation on its internal document model.

wysihtml is an extended and less strict approach on xing/wysihtml5 open source rich text editor. The code is library agnostic and has all dependencies bundled, no jQuery, Prototype or similar is required. The currently bundled dependencies are rangy.js (including textrange and selectionsaverestore modules) and base.js. This project is supported by Voog. It’s an open source, community developed wysiwyg html rich text editor. Any web developer can grab it and use it in her projects. Fast and lightweight, auto-linking of urls as-you-type, valid, semantic HTML5 (even when pasting from Word), no iframes required, no jQuery required, and it's modular, so you can add your own tools. Object namespace is now wysihtyml (was previously wysihtml5). This change includes all classnames and event names. The default toolbar is separated to independent module (wysihtml.toolbar.js) and must be added separately if used.
