It may work, if you have html enabled in your wiki - but marquee does not belong to the html-standard (and I don't like this element).
If you do not want to allow html, you may write a little plugin to include marquee:
Look at
http://www.heine-wiki.de/Playground
take the code of my Blockquote-Plugin and rename every (!) "blockquote" to "marquee" - instead of my <bq>some text</bq> you may use <mq>...</mq>
so
function connectTo and
function postConnect will be
function connectTo($mode) {
$this->Lexer->addEntryPattern('<mq>(?=.*\x3C/mq\x3E)',$mode,'plugin_marquee');
}
function postConnect() {
$this->Lexer->addExitPattern('</mq>','plugin_marquee');
}
[/color]
and
function render will be
function render($mode, &$renderer, $data) {
if($mode == 'xhtml'){
if ($data[1] == DOKU_LEXER_ENTER){
$renderer->doc .= '</p><marquee behavior="scroll" direction="right" loop="-1" truespeed>';
} else if ($data[1] == DOKU_LEXER_UNMATCHED){
$renderer->doc .= $renderer->_xmlEntities($data[0]);
} else if ($data[1] == DOKU_LEXER_EXIT){
$renderer->doc .= '</marquee><p>';
}
return true;
}
return false;
}
[/color]
It will not give you the possibility to change direction, speed etc. but it should work - I used code from
