</style><script language="JavaScript">
//读取框
var t_id = setInterval(animate,20);
var pos=0;
var dir=2;
var len=0;
function animate()
{
var elem = document.getElementById('progress');
if(elem != null) {
if (pos==0) len += dir;
if (len>32 || pos>79) pos += dir;
if (pos>79) len -= dir;
if (pos>79 && len==0) pos=0;
elem.style.left = pos;
elem.style.width = len;
}
}
function remove_loading() {
this.clearInterval(t_id);
var targelem = document.getElementById('loader_container');
