JavaScript WYSIWYG Algorithm

Despite my searches on SO, it appears that most questions revolve around simply making a div editable using contenteditable="true".

I am interested in finding the most effective method for tracking all formatting tags applied to a document. Merely toggling selected text with jQuery seems to cause issues as overlapping tags can corrupt the document after multiple edits.

Would it be more appropriate to separate each character into an array, establish a strategy for adding/modifying/removing tags based on window.getSelection(), and then generate an output version to insert back into the editable div? Or is there a superior alternative?

Answer №1

Instead of manually wrapping elements in tags with JavaScript/jQuery, I have discovered the execCommand() function which is widely supported and allows for various formatting options like those found in WYSIWYG editors. This includes color, font size, family, adding links, etc. While my initial question may have been broad, I hope this information can guide others in the right direction as well.

For example:

document.execCommand('bold', 0);
document.execCommand('forecolor', 0, '#ff0000');
document.execCommand('fontSize', 0, '7');

This functionality works in Chrome, Firefox, and Safari, though its compatibility with Internet Explorer is currently uncertain. The bold example above illustrates how the browser can maintain existing formatting and toggle styles on and off accordingly.
