javascript - JSP - session is undefined? -


i'm trying pass variable between 2 jsp files, when come use them, error saying 'session undefined'

i'm using following:

jsp1: //following function called on button press function clickandclose() {     session.setattribute("test", "some value here");      window.close();  }  jsp2: <!doctype html> <html> <body> show selected rs number     <script language="javascript">         string number = session.getattribute("test");         session.removeattribute("test");         document.write(number);     </script> </body> </html>

the fact error on session.setattribute confuses me, thought session implicit object (included?) ?

note: i'm getting error on session.setattribute("test", "some value"); , saying session undefined, not string text = session.getattribute("test");

you trying use session inside <script language="javascript"> tag, not available there. use inside scriptlet or jstl tags.

javascript executed in client side, whereas jsp implicit objects available , executed in server side

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
