Ciao ragazzi,Premetto subito che cerco un codice in PHP (come se non bastasse la sezione in cui posto),ho una pagina con un javascript che mi permette di fare drag & drop (serve solo a quello poi il java non c'entra è)con degli elementi solo che quando aggiorno la pagina questi elementi ritornano nella loro posizione iniziale e non dove li ho lasciati.Avrei bisogno di poter memorizzare queste posizioni,magari con un pulsante ,ma anche di poter modificarle nuovamente in futuro se volessi.E' possibile una cosa del genere?
Posto la pagina: (per scrupolo tanto qualcuno poi la chiede)
<head>
<style type="text/css"> .dragme{position:relative;cursor: pointer; cursor:hand}</style>
<script type="text/javascript">
var ie=document.all;
var nn6=document.getElementById&&!document.all;
var isdrag=false;
var x,y;
var dobj;
function movemouse(e){
if (isdrag){
dobj.style.left = nn6 ? tx + e.clientX - x : tx + event.clientX - x;
dobj.style.top = nn6 ? ty + e.clientY - y : ty + event.clientY - y;
return false;
}
}
function selectmouse(e){
var fobj = nn6 ? e.target : event.srcElement;
var topelement = nn6 ? "HTML" : "BODY";
while (fobj.tagName != topelement && fobj.className != "dragme"){
fobj = nn6 ? fobj.parentNode : fobj.parentElement; }
if (fobj.className=="dragme"){
isdrag = true;
dobj = fobj;
tx = parseInt(dobj.style.left+0);
ty = parseInt(dobj.style.top+0);
x = nn6 ? e.clientX : event.clientX;
y = nn6 ? e.clientY : event.clientY;
document.onmousemove=movemouse;
return false;
}
}
document.onmousedown=selectmouse;
document.onmouseup=new Function("isdrag=false");
