How to transform html codes within textarea while typing, as text editors do? I searched a lot, but preview is outside the textarea (which is very simple by jquery). I want to know the trick text editors do to display formatted html inside the textarea!
Note that I do not want a text editor, I want to show markeup when typping; for example displaying BOLD when typing <b>BOLD</b> inside textarea.
textarea does not have such a feature. However, you can still achieve the same effect with some Javascript acrobatics.
