How Do I Write This Simple JavaScript In VB Instead?

Hello forum
I'm just wondering how to write this code in VB.  It is a code that chooses the location of the vertical scroll after the page loads.
 
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(pageLoaded);
 
{
window.scrollTo(0,888);
}
 
function pageLoaded(sender, args)
 
Thank you.
