在同一页面增加多个拖动对象，也就是多个图片，在指定区域内拖动，学习JS拖动值得一看。

{
    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");
