Привет всем! выручайте завтра экзамен надо сделать сайт с использованием JAVA. Как бы html знаю а вот java (( Скачал типо примера но в нем не хрена не могу понять что и где а как ни как надо будет преподу рассказывать что и как.

Ну,во-первых, не java,а javascript. А во-вторых,как сказал GreenBear - тебе столько кода вряд-ли возьмется ктонить комментировать...да и в чужом коде оч сложно копаться)
Вообще, закинь свой скрипт подальше. Ты врятли сможешь обьяснить преподавателю как строить динамическое красивое меню на JavaScript'е Вот, написал тебе пример на JavaScript'е, который определяет браузер, и текущее время. Погугли, найдёшь как определять ОС и т.п Этого думаю вполне достаточно HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title>.: :.</title> <script type='text/javascript'> function BrowserName() { var span = document.getElementById('browser'); if(window.opera) { span.innerHTML = 'Opera'; return true; } if(document.all) { span.innerHTML = 'IE'; return true; } if(document.layers) { span.innerHTML = 'NN4'; return true; } if(window.XMLHttpRequest) { span.innerHTML = 'Mozilla (FireFox)'; return true; } span.innerHTML = 'неизвестный браузер'; return true; } function OsDet() { var osdetect = document.getElementById('osdetect'); osdetect.innerHTML = navigator.userAgent; } function CurrDate() { var currdate = document.getElementById('currdate'); current_date = new Date(); currdate.innerHTML = current_date; } </script> </head> <body onload='BrowserName(); OsDet(); CurrDate();'> <p>Ваш браузер: <span id='browser' style='color: red'></span><br /> Заголовки браузера: <span id='osdetect' style='color: red'></span></p> <p>Текущая дата: <span id='currdate' style='color: red'></span><br /></p> </body> </html> Код погуглил и скомпоновал в одно. Маленькие изменения добавил
Экзамены 23 сентября?) В любом случае, код из разряда мега-функций getProperty, может, чуть лучше: Code: function getProperty(object, str) { return eval('object.' + str); }; За один день всё равно не научишься. хммм...
