var name = $('#txtname').val();
alert(name);

few diff betwn keypress and keydown :-

1.keydown event detects special keys like CTRL,ALT,ESC etc. but keypress won't.
2. keydown is case insenitive i.e it considers ASCII code of a =65 and A = 65.
While keypress considers A=65, a=97.

Hai suresh brother. I am a Beginner. But i found very small mistake in this code.
$('txtdetails').keyup(function() ----> Before write Id name should be use #.
its not a big mistake.. But am a Beginner So, Please avoid that kind of mistake.
