I used to use this to prevent (by first asking if the user is sure (s)he wants to leave) the usage of the browser's back button or the closing of the tab/window before completing the survey:
Code:
function goodbye(e) {
if(document.limesurvey.move.value == '')
{
if(!e) e = window.event;
//e.cancelBubble is supported by IE - this will kill the bubbling process.
e.cancelBubble = true;
e.returnValue = 'Sind Sie sicher, dass Sie die Seite verlassen möchten? Eingegebene Daten werden unter Umständen nicht gespeichert.'; //This is displayed on the dialog
//e.stopPropagation works in Firefox.
if (e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
}
}
}
window.onload=function() { document.limesurvey.move.value = ''; }
window.onbeforeunload=goodbye;
The variable document.limesurvey.move seems to have been removed in the current version (2.05+ b140302). Is there a good alternative? I wonder why this is not part of the core functionality because the survey can break on improper use of the back button - and also some people forget about the survey the already opened and are reminded before they close it... But anyways, I can solve it myself but find it hard to detect which activity is "proper use" and which is not.
Is this really a non-issue for everyone else? What if someone wants to go back and uses the "back" button? Do you just accept that this participant will drop out of the survey because it will show "document expired"?
Not sure it work on all browser, but you can use your own 'identifier'
Try this:
Code:
function goodbye(e) {
if(!$('#submitted').length)
{
if(!e) e = window.event;
//e.cancelBubble is supported by IE - this will kill the bubbling process.
e.cancelBubble = true;
e.returnValue = 'Sind Sie sicher, dass Sie die Seite verlassen möchten? Eingegebene Daten werden unter Umständen nicht gespeichert.'; //This is displayed on the dialog
//e.stopPropagation works in Firefox.
if (e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
}
return 'Sind Sie sicher, dass Sie die Seite verlassen möchten? Eingegebene Daten werden unter Umständen nicht gespeichert.'; // For chrome
}
}
window.onbeforeunload=goodbye;
$(document).on('click',".button,[name='move']", function(event){
$('body').append('<input type="hidden" id="submitted" />');
});

Because : user are master of their browser. If user want to close their browser, let them close their browser, or click previous or reload etc ....
Maybe

Just kidding... I just think especially the use of the "back" button often happens because people are used to it. Also, I'm not disabling functionality, just making sure that it really is what the user wants.
But yeah, I get your point and why such functionality might not be part of the original LS code. Still, I think it should be.

(BTW: The code above does not seem to work yet, I will get back on that Monday...)

It seems it will jump to next compulsory question. If I have 50 questions on 50 different pages. Each question are compulsory. Now I want to test skip logic around Q40. Currently, I have to answer all the questions up to Q40. Are we able to let question index jump to Q40 directly? It will save a lot of time when testing.
No .... stop at first error, but don't stop at actual page.

Denis, thanks again for your solution! The reason why it did not work for me was that I changed the wrong template - d'oh!
But I have one (I think quite important) addition to your code. In order for participants to be able to leave the survey without a message AFTER completing, I added another condition to the if-statement:
