Allora io ho trovato questo codice in JavaScript...ma non ho capito bene come funziona...perchè:
tooltip.js
Codice PHP:
/*
Simple Image Trail script- By JavaScriptKit.com
Visit http://www.javascriptkit.com for this script and more
This notice must stay intact
*/
var w=1
var h=1
if (document.getElementById || document.all)
document.write('<div id="trailimageid" style="position:absolute;visibility:hidden;left:0px;top:-1000px;width:1px;height:1px;border:4px solid #f8f8f8;background:#cccccc;"><img id="ttimg" src="img/s.gif" /></div>')
function gettrailobj()
{
if (document.getElementById) return document.getElementById("trailimageid").style
else if (document.all) return document.all.trailimagid.style
}
function truebody()
{
return (!window.opera && document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}
function hidetrail()
{
document.onmousemove=""
document.getElementById('ttimg').src='/img/s.gif'
gettrailobj().visibility="hidden"
gettrailobj().left=-1000
gettrailobj().top=0
}
function showtrail(width,height,file)
{
if(navigator.userAgent.toLowerCase().indexOf('opera') == -1)
{
w=width
h=height
// followmouse()
document.getElementById('ttimg').src=file
document.onmousemove=followmouse
gettrailobj().visibility="visible"
gettrailobj().width=w+"px"
gettrailobj().height=h+"px"
}
}
function followmouse(e)
{
if(navigator.userAgent.toLowerCase().indexOf('opera') == -1)
{
var xcoord=20
var ycoord=20
if (typeof e != "undefined")
{
xcoord+=e.pageX
ycoord+=e.pageY
}
else if (typeof window.event !="undefined")
{
xcoord+=truebody().scrollLeft+event.clientX
ycoord+=truebody().scrollTop+event.clientY
}
var docwidth=document.all? truebody().scrollLeft+truebody().clientWidth : pageXOffset+window.innerWidth-15
var docheight=document.all? Math.max(truebody().scrollHeight, truebody().clientHeight) : Math.max(document.body.offsetHeight, window.innerHeight)
if (xcoord+w+3>docwidth)
xcoord=xcoord-w-(20*2)
if (ycoord-truebody().scrollTop+h>truebody().clientHeight)
ycoord=ycoord-h-20;
gettrailobj().left=xcoord+"px"
gettrailobj().top=ycoord+"px"
}
}
pagina.html
Codice PHP:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Nuova pagina 1</title>
<script language="javascript" src="tooltip.js"></script>
</head>
<body>
<a href="#" onmouseover="showtrail(400,300,'via%20dei%20Mari%20371.png');" onmouseout="hidetrail();">via dei Mari, 375</a>
<p></p>
</body>
</html>
Ma quando vado nel collegamento spunta l'img con la X come se fosse errata la posizione..perchè?
Eppure tutti i file si trovano in "Documenti" sul mio PC...
Come mai si vede la X?
Grazie 1000...ciao Davide! ^^
