I created a custom timer using JS that goes across all the pages of questions in the block. Participants see the timer as they answer questions on all 9 pages and then after 5 min, they are automatically advanced to the next block. I have the code below on Page 1 and each subsequent page has only a "display if timeRemaining greater than 0." My issue is that since the timer code is only on the first page, if participants (for whatever reason) refresh the page on pages 2 to 9, the timer will disappear and they will not be autoadvanced in my survey. They are trapped in on that page. What can I do to make sure if they refresh on pages 2 to 9 that the timer will reappear, keep counting and auto-advance them once 5 minutes is up?

This is my code for the first page

Qualtrics.SurveyEngine.addOnload(function()

{

var header = document.createElement("div"); 

 header.className = "header" 

 header.id = "header_1"; 

var timer = document.createElement("div"); 

 timer.className = "timer"; 

 timer.id = "timer_1"; 

 timer.innerHTML = "Time Remaining: 03:00"; 

header.appendChild(timer);

document.body.insertBefore(header, document.body.firstChild);

function startTimer(duration, display) { 

 var timer = duration, minutes, seconds; 

var myTimer = setInterval(function() { 

 minutes = parseInt(timer / 60, 10) 

 seconds = parseInt(timer % 60, 10); 

 minutes = minutes < 10 ? "0" + minutes : minutes; 

 seconds = seconds < 10 ? "0" + seconds : seconds; 

 var text = ('innerText' in display)? 'innerText' : 'textContent';

 display[text] = minutes + ":" + seconds; 

	Qualtrics.SurveyEngine.setEmbeddedData('timeRemaining', timer);

if (--timer < 0) { 

 clearInterval(myTimer); 

 timeOver(); 

 } 

 }, 1000); 

 } 

 var timerSeconds = 180, 

 display = document.querySelector('#time'); 

 startTimer(timerSeconds, display); 

 var timeOver = function() { 

 $('NextButton').click();

 document.getElementById("timer_1").innerHTML = ""; 

 x = 1; 

 var bgColor = setInterval(change, 1000); 

 } 

});

Qualtrics.SurveyEngine.addOnReady(function()

{

});

Qualtrics.SurveyEngine.addOnUnload(function()

{

	/*Place your JavaScript here to run when the page is unloaded*/

});
