Oscriptel = document.createelement ("script");
Oscriptel.type = "Text/javascript";
Oscriptel.language = "JavaScript";

Oscriptel.onreadystatechange = DoCallback;

Oscriptel.onload = function ()
{
This.readystate = "complete";
DoCallback ();
if (typeof (Lianbo) = = "Object") {
Lianbo.init (window. QVPL);
}
};

OTIMEOUTHDL = Window.settimeout (doerror,script_timeout);
document.getElementsByTagName ("Head") [0].appendchild (Oscriptel);

function DoCallback ()
{
if (oscriptel.readystate = = "complete" | | | oscriptel.readystate = = "Loaded")
{
Oscriptel.onload = Oscriptel.onreadystatechange = new Function ();
Window.cleartimeout (OTIMEOUTHDL);
}
