нужна помощ Создание сайта с java
 
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.

Плиз помогите разобрать код.......

// make the menus and provide information on usage
//================================================== ==================================
//
// In order to customise your menus all you need to do is:
// - edit the styles .dot, .dotoff and .caption
// - add the main menu using the following code
// var [menu_name] = new menuObject("[menu_name]", [x position], [y position], [caption], [spacing between sub menus]);
// - add the subemus using:
// var [sub_menu] = [menu_name].addItem([caption],[action],[spacing]);
// OR
// var [sub-sub_menu] = [sub_menu].addItem([caption],[action],[spacing]);
// OR
// [menu_name].subMenus[x].addItem([caption],[action],[spacing]);
//
// - where action is string that get's evaluated when the dot is clicked
//
// (NOTE the spacing is optional and if left blank gets inherited
// and is equal to the (parent's value)/2 - the default for
// the main menu item uis 400)
//
// - the following allow extra manipulation of the menus:
// + menuItem.show() - show's the menu's dot
// + menuItem.showCaption() - show's the menu's caption
// + menuItem.hide()
// + menuItem.hideCaption()
// + menuItem.startAngle = x - default is 0-degrees which means the first submenu appears
// directly to the right, the following items are traced in a
// clockwise direction
// + menuItem.setCaption("text") - allows you to change a menus caption
// + menuItem.expand() - opens a menus submenus (if they exist)
// + menuItem.collapse() - closes a menu's subItems (unless one of them is open)
//
// + menuItem.moveMe(x,y) - moves a menu to coordinates (x,y)
// + menuItem.moveBy(x,y) - moves a menu by (x,y)-pixels
// + menuItem.x() & menuItem.y() - retrieve a menus coordinates
//
//================================================== ==================================

Эм...а что именно непонтяно-то?


PS: http://www.segfault.kiev.ua/smart-questions-ru.html

o55rus 22.09.2008 09:38
сам код java что и как тут написано плиз выручайте

GreenBear 22.09.2008 09:40
омг, кто тебе будет столько кода комментировать ?

biophreak 22.09.2008 09:48
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)

В школах яваскрипт учат :)

n3m0 22.09.2008 11:49
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

Код HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

  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

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.

Плиз помогите разобрать код.......
Экзамены 23 сентября?)
В любом случае, код из разряда мега-функций getProperty, может, чуть лучше:
Код:
function getProperty(object, str)
{
  return eval('object.' + str);
};
За один день всё равно не научишься.
