[Javascript] Forum Text-Editor?

[SineCosine]

Notice that when you highlight a bunch of words in this forum's 'quick reply' box and click the 'B' button, it surrounds your highlighted words with [ B ] and [ /B ] tags.

But I can't seem to do it with javascript at all ._.
Anyone know how it's done?

I would use firebug (Can't remember the firefox-extension name) to check..
But I don't have a PC anymore >.>

So..
What exactly goes on when I click the 'B' button?

Ask Google to find you some info on window.getSelection and document.selection.createRange().

As usual, IE does its own thing yet again...


Most people don't write that stuff on their own though:

Thanks, celerisk!

Also the YUI Rich Text Editor is worth a looking at.
