room to write

Apologies for the less-than-fully-assed entry that follows:

I thought a pretty common task for jQuery would be to make a textarea automatically expand as content was added into it. And a bit of googling shows that a number of people have taken a stab at it. But it looks like no one has gotten it quite right, and I don't have enough time and energy to fix that.

The best I found is padolsey's jQuery.fn.autoResize. Once you include the .js file usage is trivial:

$(document).ready(function() {

There are some configuration options as well.

I'm not 100% enamored of it: if you edit the value manually (like by calling $("textarea").val()) , the thing is not resized, and while it has basic coverage for resizing when users paste in text, it gets a bit wonky.
