popup automatically close on the next page.

Hi all, I created this popup, but the popup stays open even when participants proceed to the next page. How can I make automatically closed at the next page? I need this popup to be closed on the next page, if participants don't close on this page. This is my code: Qualtrics.SurveyEngine.addOnload(function() { }); Qualtrics.SurveyEngine.addOnReady(function() { jQuery("[id*='dialog']" ).dialog({ autoOpen: false}); var delayTime = 3000; //This is the time of delay setTimeout(function(){jQuery("[id*='dialog']" ).dialog({ autoOpen: true, draggable:true, scroll:false, height:'auto', width:'750x', open: function(event,ui){ $(event.target).parent().css('position', 'fixed'); $(event.target).parent().css('top', '50px'); $(event.target).parent().css('left', '500px'); } })}, delayTime); }); Qualtrics.SurveyEngine.addOnUnload(function() { });
