It seems that there're bug in Firefox and Chrome in Ubuntu 12.04
Textchange worked perfectly in all browsers for Ubuntu linux, but 2 days ago it stopped to work both in Firefox and Chrome at the same time. But in Opera it continued to work, very strange.
Then i upgraded my browsers, and the problem has gone.

Doesn't work on latest version of chrome
29.0.1547.66 (Official Build 220848)

Ditto, the demos on this page seem to be broken for Chrome Version 31.0.1650.48 http://zurb.com/playground/jquery-text-change-custom-event

It doesn't work on Chrome and Firerox.. any idea?

I was testing into Chrome and not works. Anyways i will work on your code, you saved Zeokat tons of work.

An event is not performed.

1.$("textarea").val("test1\ntest2");
2.selected delete textarea value;

Because it uses keyup to decide if it should trigger it won't work with multi keystroke characters like ü or many Chinese characters. It triggers on the first keystroke rather than on the full character after the second keystroke.

The examples are not working on this page http://zurb.com/playground/jquery-text-change-custom-event
