How to detect a textbox's content has changed

Question

I want to detect whenever a textbox\'s content has changed. I can use the keyup method, but that will also detect keystrokes which do not generate letters, like the arrow ke

Answer 1

The 'change' event doesn't work correctly, but the 'input' is perfect.

$('#your_textbox').bind('input', function() {
    /* This will be fired every time, when textbox's value changes. */
} );
