// Das Newsboard wartet noch auf das Vervollständigen seiner Funktionen.
|
||||||
|
|
||||||
|
// 1. Belege die Links » und « mit Funktionalität. Der Link mit der Aufschrift « soll es erlauben, zur ersten Nachricht zu springen, der Link » zur letzten.
|
||||||
|
|
||||||
|
// 2. Der bisher eher sinnlose rote Kreis in der linken oberen Ecke soll nun die Gesamtanzahl der Nachrichten anzeigen. Schreibe eine Funktion, die diese Anzahl ausliest und in das <span> mit der Klasse message_number einträgt.
|
||||||
|
|
||||||
|
// 3. Unterstütze ab sofort das Navigieren durch die News mit der Tastatur. Die Pfeiltasten nach links und rechts sollen dabei jeweils die gleiche Funktionalität wie die Buttons < und > ermöglichen.
|
||||||
|
|
||||||
|
// 4. Auch das Springen auf die erste bzw. letzte Position soll nun mit Tastatur möglich sein. Die Tastenkombination dafür ist alt und die Pfeiltaste nach links (zur ersten Nachricht) bzw. rechts (zur letzten Nachricht).
|
||||||
|
|
||||||
|
// Übung 9: Newsboard: Jetzt ist aber Schluss!
|
||||||
|
|
||||||
|
// Die neuen Features des Newsboards sind schon fast fertig. Problematisch ist aber, dass die Vorwärts- und Rückwärts-Buttons auch aktiv sind, wenn es keine vorige bzw. nächste Nachricht mehr gibt. Dies führt zu einem sehr unschönen Fehler.
|
||||||
|
|
||||||
|
// 2. Sorge dafür, dass die Vor- und Rückwärts-Buttons jeweils deaktiviert werden, sobald der Anwender am Anfang bzw. Ende der Nachrichtenliste angekommen ist.
|
||||||
|
|
||||||
|
// 3. Auch die Buttons, die den Anwender zur ersten bzw. zur letzten Nachricht führen, sollen deaktiviert sein, sobald sich der Anwender bei der ersten bzw. letzten Nachricht befindet.

<h2>Übung 10 - Chasing Lights</h2>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
Eine erste Variante sind die chasing Lights. Dabei muss der Anwender das Lauflicht mit der Maus »jagen«. Immer
|
||||||
|
wenn der Mauszeiger sich über einer Glühbirne befindet, schaltet sich die nächste Birne ein und die aktuelle
|
||||||
|
aus. Versucht der Benutzer, mit dem Mauszeiger die leuchtende Glühbirne zu berühren, springt das Licht auf die
|
||||||
|
nächste über. Er »jagt« quasi das Lauflicht. Bei der letzten Lampe beginnt das Spiel wieder von vorn!
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Programmiere ein weiteres Lauflicht. Diesmal soll das Lauflicht weiterspringen, wenn der Benutzer auf eine der
|
||||||
|
Lampen klickt. Auch hier gilt: Nach der letzten Lampe fängt das Licht wieder von vorn an zu laufen.
|
||||||
|
