Salve a tutti dovrei usare un codice Js in più parti in una pagina, ora incollandolo + volte nella varie parti della pagina non funziona; l'idea sarebbe scriverlo in un file .js e poi ri chiamarlo nelle varie parti della pagina; il problema e che non so quale parte di codice va nella pagina e poi come va richiamato dove mi serve, chi mi spiega?
Il codice è questo:
Codice PHP:
<script type="text/javascript">
 
    var galleryspeed=2 
  
    var galleryanchor="450px"
 
    var galleryalt="115px"
 
    galleryback="#000000"
 
    var slidespace=5
    var imagespace=""
    var galleryimage=new Array()
    var endphoto=''
 
    galleryimage[0]='<a href="http://www.ideepercomputeredinternet.com/search/label/add-on" target="blank"><img border="0" src="https://lh4.googleusercontent.com/_nT13UtBmmiU/TUpyoOtBKeI/AAAAAAAARrw/bufdtmNXtjA/alba1X.jpg" title="post con etichetta add-on" alt="Titolo Miniatura"></a>'
 
    galleryimage[1]='<a href="http://www.ideepercomputeredinternet.com/search/label/annunci" target="blank"><img border="0" src="https://lh4.googleusercontent.com/_nT13UtBmmiU/TUpyoMAlRuI/AAAAAAAARr0/kBEWibne4-I/alba2x.jpg" title="post con etichetta annunci" alt="Titolo Miniatura"></a>'
