Qualtrics - progress to next block when time is up

问题

I need a survey to auto progress to the next block when a specified time limit has been reached for the previous block. Currently I am using the below script to display the timer but need the script to execute the action when time has elapsed. Any assistance is greatly appreciated.

Javascript in timing question.

Qualtrics.SurveyEngine.addOnload(function()
{
    var headerCont = document.createElement("div");  
 headerCont.className = "header-cont";  
 headerCont.id = "header_container";  
 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: <span id='time'>00:10</span>";  
 headerCont.appendChild(header);  
 header.appendChild(timer);  
 document.body.insertBefore(headerCont, 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;  
   if (--timer < 0) {  
    clearInterval(myTimer);  
    timeOver();  
   }  
  }, 1000);  
 }  
 var timerSeconds = 10,  
 display = document.querySelector('#time');  
 startTimer(timerSeconds, display);  
 var timeOver = function() {  
     document.getElementById("timer_1").innerHTML = "Time is up.";}



});

CSS

    .header-cont {  
   width:100%;  
   position:fixed;  
   top:0px;  
   z-index:1000;  
 }  
 .header {  
   height:75px;  
   background:#FFFFFF;  
   width:100%;  
   margin:0px auto;  
 }  
 .timer{   
   margin: auto;  
   text-align: center;  
   vertical-align: middle;        
   font-size: 200%;
    font-family: Arial;
 }

EDITED ANSWER BASED ON COMMENT:

Initialize an embedded data field in the survey flow before block:

blockTimeFlag = 0

Add the following lines to the timeOver function:

Qualtrics.SurveyEngine.setEmbeddedData("blockTimeFlag", "1");    
$('NextButton').click();

However, this means that none of your questions can be forced response.

Add display logic to your questions:

if blockTimeFlag = 0
