I'm very new to JavaScript, and I'm currently trying to add a custom code to my Qualtrics survey that makes it so pressing the enter key continues the survey. I have a code that should be working; however, I'm getting an "Unexpected token )" error.
Here is the code:
Qualtrics.SurveyEngine.addOnload(function()
{
document.addEventListener("keydown", function(e) {
if (e.keyCode === 13) {
function(){
that.clickNextButton();
}
}
}
});
the "clickNextButton" function was found in the Qualtrics API document and is supposed to emulate the next button click. The function is clickNextButton(), but the example provided has the code as that.clickNextButton().
The example they use is below:
//Hides the next button and displays the question
//for 5 seconds before moving to the next page
this.hideNextButton();
var that = this;
(function(){that.clickNextButton();}).delay(5);
I don't need the hiding button function or the delay, but just wanted to include an example of how it is used.
Any help is much appreciated, thanks in advance!
Here is a simplified version that works (updated to hide NextButton):
Qualtrics.SurveyEngine.addOnload(function() {
$('NextButton').hide();
document.on("keydown", function(e) {
if (e.keyCode === 13) $('NextButton').click();
});
});
It depends on the scope, or specifically where the function clickNextButton resides.
If you don't bother with the timeout you should be able to just remove the word 'that' from your Qualtrics.SurveyEngine function and it should work fine.
It's possible the function is not available in your current scope. So if removing 'that' doesn't work. Put it back in and put var that = this; in the line before your function call. It's far from a tidy way to do things at all but it may fix things for you.
Worth reading this.

Didn't Meatloaf say something like... I'd do anything for scope.... but I don't do THAT?
As said in my comment...See if it solves your error
Qualtrics.SurveyEngine.addOnload(function()
{
document.addEventListener("keydown", function(e) {
if (e.keyCode === 13) {
function(){
that.clickNextButton();
}
}
} ); // here was a missing bracket here
});
So I have a video embedded in a question and I needed to disable to Next button for 15 seconds in that way I would know that autoplay video was watched.
And this worked for me so well:
Qualtrics.SurveyEngine.addOnload(function()
{
//Hides the next button and displays the question
//for 15 seconds before moving to the next page
this.disableNextButton();
var that = this;
(function(){that.enableNextButton();}).delay(15);
});
You can change the (15) seconds to any number, the Next Button will be activated and ready to be clicked next, but not automatically send you to next page.

I am designing an experiment in qualtrics using java script. For each question in my study, a participant needs to guess the correct answer, type it in, and then hit the space button. Once they hit the space button, a logic checks whether their answer is correct or not. If the answer was correct, a sound should be played for 1.2 seconds, the background color should change into red for a second and then back to white, and lastly the experiment should automatically moves on to the next question.
So far, I figured out the correct sequence of commands. However, it seems like i am not using the setTimeout logic correctly. no matter what combination of timeout values I used, I couldn't get it play all the middles steps, including the audio play and red background flash, before the screen moves to the next question.
Here, I 've shared my code. I would very much appreciate any help.
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/
});
Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
var qid = this.questionId;
var changepage = null;
/*focus on the box*/
jQuery("#"+qid+" .InputText").select().focus();
document.onkeydown = function(event) {
console.log('keydown',event);
if (event.which == 32) { //hit the space button
event.preventDefault();
//read the input
input = jQuery("#"+qid+" .InputText").val();
console.log(input);
if (input.trim().toLowerCase() == "cat") {
//alert(input.trim().toLowerCase());
document.getElementById("correct").play(); //play the correct sound which is 1.2seconds long
setTimeout(jQuery("body").css("background-color","red"), 3000); // change the background color
setTimeout( jQuery('#NextButton').click(), 2000) //move on to the next question
} //end of if
} // end of if 32
} //end of down button
});
Qualtrics.SurveyEngine.addOnUnload(function()
{
jQuery("body").css("background-color","white");
});
setTimeout is asynchronous. If you want multiple setTimeouts to execute in a fixed order then the times have to be additive. So your NextButton timing should be 5000ms (3000ms + 2000ms).
Alternatively, you could put the NextButton click inside the background color change setTimeout function. To add to that, could you put both inside an 'ended' event on your audio.
if (input.trim().toLowerCase() == "cat") {
//alert(input.trim().toLowerCase());
//play the correct sound which is 1.2seconds long
vid.play();
vid.onended = function()
{
jQuery(".skirt").css("background-color","red");
jQuery('#NextButton').click();
};
} //end of if
I am running a page with a timer that I'm using to run in a iframe of a page so that I know that someone was on there actually with window in focus paying attention to screen and if leave have the timer pause until back viewing the window or in focus.
I have 4 timer files: timer.css timer.js timer.php & timerb.js
I believe I would execute it in the following file and code, but that is where I am stuck as don't know what or where to add it for sure and no luck yet and why here asking so please take a look and let me know if you can help.
File: timer.js
function adTimer() {
timer++;
if(timer == fulltimer) {
var show="Click "+key;
$("#buttons").fadeIn();
$("#timer").html(show);
}
else {
setTimeout(adTimer, 1000);
}
$("#bar").width((timer/fulltimer)*200);
}
This could be enough for you:
$(window).blur(function(){
//your code for inactive
});
$(window).focus(function(){
//your code for active
});
or non jQuery solution (https://stackoverflow.com/a/1760283)
window.onblur = function () {
//your code for inactive
};
window.onfocus = function () {
//your code for active
};
if not try Page Visibility API (answer already here https://stackoverflow.com/a/1060034)
Just wondering why all that implementation if JQuery already provide a timeout. did you try to use set Timeout.

I'm trying to have a stop watch stop when 5 divs have been clicked. Then i would like to insert this record time into a seperate div and display it to the person in question. The stop watch and clicking works fine but i can't seem to get the message to show.
$(".masterobject").click(function() {
$(this).addClass("clicked");
if ($(".masterobject").length == $(".clicked").length){
pause();
var myrecordtime = document.GetElementById("yourtime");
$("#success").show();
$("#success").text('Congratulations! Your score is' + myrecordtime)
}
});
the masterobject class are the clicked divs. The pause() var works fine and after that is a mess. What is the correct way make sure the if statement runs all of this? Thanks in advance.
full code with the stop watch at http://jsfiddle.net/8qmyg/306/
After experimenting some more i solved it by changing the variable.
$(".masterobject").click(function() {
$(this).addClass("clicked");
if ($(".masterobject").length == $(".clicked").length){
pause();
$("#success").show();
var recordtime = $("#yourtime").text();
$("#success").html("congratulations your time is" + recordtime)
}

I'm trying to limit the user's ability to click on an object to a certain time limit. I looked around and found that apparently, setTimeout() is the correct function to use for this type of thing. I've applied the function to my code, but its not working. I'm thinking/know now that the problem is that the setTimeout in my code isn't limiting the actual click event, which I need to do. Here is a snippet of my click code:
function clickRun(event) {
var $objectVersion = correspondingObject(event.target.id);
if (isAnyVisible() == false) { // none open
$objectVersion.makeVisible();
} else if (isAnyVisible() && $objectVersion.isVisible()) { //click already open div
$objectVersion.makeInvisible();
} else if (isAnyVisible() && $objectVersion.isVisible()==false) { //different div open
searchAndDestroy();
$objectVersion.delay(600).makeVisible();
};
};
$('.ChartLink').click(function(event) {
setTimeout(clickRun(event),5000);
});
I've also created a JSFiddle to represent what I'm talking about: http://jsfiddle.net/FHC7s/
Is there a way to achieve limiting the actual click detection on the page?
I think the easiest way to do it is to keep track of the time of the previous click and if the current click is too soon after that, then don't do anything:
onClick = function(){
if(new Date().getTime() - lastCheck < MIN_CLICK_SPACING) return;
}
Have a look at this JSFiddle, I've set it up so you can have the button disable itself for time duration after detecting a click. Just make sure to remember how your closures are operating with your setTimeouts.
Your code contains an error... your line should be
setTimeout(function(){clickRun(event)},5000);
but even then I don't think that's exactly what you're looking for; that code will "delay" the click by 5 seconds, not actually prevent more clicks. If your true intent is to ignore all clicks after a certain amount of time, then I would go with mowwalker's answer; there's no way to stop the clicks, but you can check to see if you should honor them or not.
I want that when mouse is over an image, an event should be triggered ONCE, and it should be triggered again only after mouse is out of that image and back again, and also at least 2 seconds passed.
If I leave my mouse over the image,it gets called like every milisecond,and by the logic of my function once you hover on the variable 'canhover' becomes 0 until you move mouse out
This code seems to have a bug and I cant see it. I need a new pair of eyes, but the algorithm is kinda logical
Working code :
<script type="text/javascript">
var timeok = 1;
function redotimeok() {
timeok = 1;
}
//
function onmenter()
{
if (timeok == 1)
{
enter();
timeok = 0;
}
}
//
function onmleave()
{
setTimeout(redotimeok, 2000);
leave();
}
//
$('#cashrefresh').hover(onmenter,onmleave);
function enter(){
$("#showname").load('./includes/do_name.inc.php');
$("#cashrefresh").attr("src","images/reficonani.gif");
}
function leave(){
$("#cashrefresh").attr("src","images/reficon.png");
}
</script>
I don't know if this will solve your entire problem (since we don't have a detailed description of what it is), but instead of:
$('#cashrefresh').hover(onmenter(),onmleave());
try:
$('#cashrefresh').hover(onmenter,onmleave);
And the same thing here:
setTimeout(redotimeok, 2000); // just the function name
Also, I don't see where you ever set timeok to zero. Do you mean to set timeok = 0 in onmenter()?
There are two methods in jquery for your problem:
.mouseenter() and .mouseleave()
Check out the demos there.
EDIT:
I thought hover was for mouseover and mouseout, sorry for confusion.
I checked your code again. And it seems that you're changing the image when mouse gets over the image, which forces browser to load the new image and the old image disappears for a very little while till the new one appears and i think this must be triggering both handlers continuosly and you're getting this behaviour.
Try not to change the source of the image, comment out that line and instead console.log("some message") there and see if the message is repeated as much as .load() was fired before.
Hope this helps.
Try changing onmleave function as follows:
function onmleave()
{
setTimeout(redotimeok, 2000);
leave();
}
