Пакунок: libjs-jquery-textchange (0.2.3-1ubuntu1)

detects text changes for input and textarea elements

Simple cross browser detection of text changes for input and textarea elements using a jQuery custom event plugin by ZURB

Implementing this requires binding events to the keyup event, and a couple other events if you want to detect text changes on cut and paste. Even if you're a JavaScript god it's tedious to keeping writing this logic over and over again. Be smart and use the ZURB text change event plugin instead.
