Answer 1

I needed this to write a unit test , for which i need to simulate a scroll event

function dispatchScroll(target,newScrollTop) {
      target.scrollTop = newScrollTop;
      var e = document.createEvent("UIEvents");
      // creates a scroll event that bubbles, can be cancelled,
      // and with its view and detail property initialized to window and 1,
      // respectively
      e.initUIEvent("scroll", true, true, window, 1);
      target.dispatchEvent(e);
    }
