Auto Scoll on a Java Frame?

[Christoph Wiese]

Hi,
I need a script to auto scroll a time schedule witch is part of a website.
The Idea is to have a Web application running where the people can see a time schedule.

It has to scroll down and up and sometimes refresh the page.

For normal webpages I created these script, witch is scrolling. But it is not working on pages that are more like an app, like the google calendar.

How can I move a scroll bar in a page not of the window?

As attachment i add a Picture of the web application I want to manipulate.



That is my Script, witch is scrolling normal webpages up and down.

var pos = 0                                                //Koordinaten Variable
var richtung = 0                                    //0= Runter, 1= Hoch
var gschwindigkeit = 20                        //Je größer der wertz umso langsamer
var weite = 5                                            //Schrittweite pro Durchgang
 
function scrollen(){
 
//Hauptfunktion 
window.scrollTo({
  top: pos,
  left: 0,
  behavior: 'smooth'
});

//Richtungswechsel und nächste Koordinate
  //Nach unten
   if(richtung == 0){ 
       if(scrollY == scrollMaxY)
        richtung = 1;
      else
        pos=pos+weite;
   }
 //Nach oben
   if(richtung == 1){
       if(pos <= 0)
        richtung = 0;
      else
        pos=pos-weite;
   }
}
setInterval(scrollen, gschwindigkeit);
