javascript - Jquery text change event -

-

i need fire event anytime content of textbox has changed.

i cant use keyup nor can use keypress.

keyup , keydown doesn't work if hold down on key.

keypress triggers before text has changed. doesn't recognize backspace or delete either.

so i'm assuming i'm going have build custom logic or download plugin. there plugins out there? or if should build one, constraints should out for?

for eg. facebook search @ top. can press , hold.

another example writing stackoverflow question. right below editor, contents copied in real time, backspace , everythng works. how it?

i took @ so's source. looks lot this:

function updatepreview(){     $('div').text($('textarea').val()); }  $('textarea').bind('keypress', function(){         settimeout(updatepreview, 1);     } );​

they stuff make html tags bold , italics , links , such , time it. increase delay 1 longer if takes long generate html.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
