ciao a tutti.. devo realizzare una tabella.. e in uno dei campi devo mettere del testo che dev'essere scrollabile tramite 2 immagini (freccia su e freccia giu'). ho cercato nel forum e ho trovato vari script... ma funzionano solo con IE.. su firefox..niente da fare. Qualcuno puo' darmi una mano?? Secodo me l'errore sta nella funzione verifyCompatibleBrowser().. ma non ci capisco niente.
(Di seguito metto il codice che ho usato)
<html>
<head>
<style type="text/css">
#divContainer{
position:relative;
width:499px;
height:244px;
overflow:hidden;
clip:rect(0,499,244,0);
visibility:hidden;
margin: 0px;
padding: 0px;
}
#divContent{
position:absolute;
top:0;
left:0;
padding:10px;
text-align:left;
}
</style>
<script language="JavaScript">
function verifyCompatibleBrowser(){
this.ver=navigator.appVersion
this.dom=document.getElementById?1:0
this.ie5=(this.ver.indexOf("MSIE 5")>-1 && this.dom)?1:0;
this.ie4=(document.all && !this.dom)?1:0;
this.ns5=(this.dom && parseInt(this.ver) >= 5) ?1:0;
this.ns4=(document.layers && !this.dom)?1:0;
this.bw=(this.ie5 || this.ie4 || this.ns4 || this.ns5)
return this
}
bw=new verifyCompatibleBrowser()
var speed=50
var loop, timer
function ConstructObject(obj,nest){
nest=(!nest) ? '':'document.'+nest+'.'
this.el=bw.dom?document.getElementById(obj):bw.ie4 ?document.all[obj]:bw.ns4?eval(nest+'document.'+obj):0;
this.css=bw.dom?document.getElementById(obj).style :bw.ie4?document.all[obj].style:bw.ns4?eval(nest+'document.'+obj):0;
this.scrollHeight=bw.ns4?this.css.document.height: this.el.offsetHeight
this.clipHeight=bw.ns4?this.css.clip.height:this.e l.offsetHeight
this.up=MoveAreaUp;this.down=MoveAreaDown;
this.MoveArea=MoveArea; this.x; this.y;
this.obj = obj + "Object"
eval(this.obj + "=this")
return this
}
function MoveArea(x,y){
this.x=x;this.y=y
this.css.left=this.x
this.css.top=this.y
}
function MoveAreaDown(move){

}
}

}

}
}
function CeaseScroll(){

objScroller.MoveArea(0,0)

}
