ResponseWrite({var output; output = 正在装载页面;dots++;if(dots>=dotmax)dots=;);

ResponseWrite(for(var x = ;x < dots;x++){output += ·;}mydivinnerText =output;});

ResponseWrite(function StartShowWait(){mydivstylevisibility = visible; );

ResponseWrite(windowsetInterval(ShowWait());});

ResponseWrite(function HideWait(){mydivstylevisibility = hidden;);
