(function() {

  var deviation = get("span[@id='zoomed-out']/a").snapshotItem(0);
  //alert(deviation.nodeName);

  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false,
false, false, false, 0, null);
  deviation.dispatchEvent(evt);


  // xpath function
  function get(query) {
    return document.evaluate(
      query,
      document,
      null,
      XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
      null
    );
  }

})();

This is my whole script. I get Error: deviation.dispatchEvent is not a
function
