javascript - How to get entered value after onkeydown? -


i'm trying new value of inputbox after entering each character if it's number. ajax in example below sends old value , not newly entered value.

for example, if value 1 , focused inputbox, deleted value , pressed 2, ajax send "1". need send "2"

html

<input type="text" class="quant-input" size="7" name="qty" value="1" onkeydown="change_qty();"/>

javascript

function change_qty(evt) {     var charcode = event.keycode     if (charcode > 48 || charcode < 57) {         jquery.ajax("page.php", {                 type: "post",                 data:'data='+$('.quant-input').val()             });         return true;     } else {         return false;     } }

the value isn't changed until keyup event. need use following instead:

onkeyup="change_qty();"

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
