Hier een chatbox geprogrammeerd met de AJAX-technologie (Asynchronous JavaScript and XML).

De installatie werkt als volgd:

Maak de volgende tabellen aan in een MySQL database:

mysql code - Bekijk de code zonder highlighting - Klap code in 
  1. CREATE TABLE `users` (
  2.   `id` INT(11) NOT NULL AUTO_INCREMENT,
  3.   `name` VARCHAR(18) COLLATE latin1_general_ci NOT NULL DEFAULT '',
  4.   `date` DECIMAL(25,0) NOT NULL DEFAULT '0',
  5.   `color` VARCHAR(7) COLLATE latin1_general_ci NOT NULL DEFAULT '#000000',
  6.   PRIMARY KEY  (`id`),
  7.   KEY `name` (`name`,`date`),
  8.   KEY `color` (`color`)
  9. ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=403 ;


mysql code - Bekijk de code zonder highlighting - Klap code in 
  1. CREATE TABLE `msgs` (
  2.   `id` INT(11) NOT NULL AUTO_INCREMENT,
  3.   `who` VARCHAR(18) COLLATE latin1_general_ci NOT NULL DEFAULT '',
  4.   `color` VARCHAR(7) COLLATE latin1_general_ci NOT NULL DEFAULT '#000000',
  5.   `msg` VARCHAR(255) COLLATE latin1_general_ci NOT NULL DEFAULT '',
  6.   `type` ENUM('msg','info','logoff','logon') COLLATE latin1_general_ci NOT NULL DEFAULT 'msg',
  7.   `date` DECIMAL(25,0) NOT NULL DEFAULT '0',
  8.   PRIMARY KEY  (`id`),
  9.   KEY `who` (`who`,`color`,`msg`,`type`,`date`)
  10. ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=2967 ;


De enige benodigde bestanden zijn index.php en server.php.

Ook heeft het script de optie om smileys te gebruiken, hiervoor kun je de smileys downloaden van: http://files.dsound.nl/smileys.rar

Het script heeft wel zijn mankementen,
in sommige browsers zal het lijken voor de gebruiker dat zijn berichten dubbel gepost worden, dit zien anderen echter niet.

Ook, omdat het script feitelijk constant server.php opnieuw inlaad, zullen sommige browsers in de statusbalk aangeven dat de website nog geladen wordt.

Verder is het een goed werken script, maar onzeker is of dit wel de ideale manier is om een chatbox te maken.

AJAX biedt namelijk veel meer mogelijkheden met zijn functionaliteiten, denk maar aan Googlemaps en Gmail, welke ook met de AJAX-technologie zijn geprogrammeerd.

Allereerst hier mijn chatbox:
