triggering a page change with code

can anyone tell me how I can code a page change event? I've got some JavaScript already running in an iAd page and I want to add some code that will change the ad to page 2 when a condition is met. In other words:

function(isConfirm){  
             if (isConfirm) { 
                  for (n = 1; n <= TotalQuestions; n++) {
                     localStorage.setItem(Place + "Key" + n, "");
                  }
                 location.reload();
               //go to page 2 here
             } else { // etc...

I have a button to run this code, clear student answers from localStorage by reducing the values to an empty string and then reload the page with blank entries from local Storage. The problem is that I have three pages and when the location is reloaded from, say, page 3, it switches back to page 1 as this is the first view that loads when the widget runs. Anyone know how to tell it to reload the widget but then go to the same page the button is on (i.e. this.viewController)?
