How to restrict how many times participant plays uploaded audio | XM Community
Skip to main content

Hi all,
I have been working on a task involving audio stimuli and a visual analog scale (VAS). After the participant clicks and plays the audio, the participant is supposed to make a judgment of the audio stimulus using a VAS. However, I only want the participants to hear the audio once.
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/
});

Qualtrics.SurveyEngine.addOnReady(function()
{
/*jQuery('audio').on('ended', function() {
    jQuery(this).css("pointer-events","none");*/
});
Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/
});

Above is the code listed in the JS section, per the recommendation of this post. Still doesn't work.

never mind! it worked!!!

Remove /* and */ from start and end. Also add closing brackets });
So the final code would be just this:
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/
});

Qualtrics.SurveyEngine.addOnReady(function()
{
jQuery('audio').on('ended', function() {
    jQuery(this).css("pointer-events","none");

});
});
Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/
});

thanks @rondev!

Hi, modifying the code from this post to hide the audio player after clicking "play"
jQuery('audio').on('play', function() {
jQuery(this).hide();
});
I also want to display a string of text afterwards that says "Audio has already been play once. Please select a response." This way, the user would understand what is going on.
I was thinking that maybe after jQuery(this).hide(), there could be jQuery(message).show()?
Anyone have any idea, how I can set this up?

honsonl ,

Add below code to existing code:
var that = this.questionId;
jQuery('audio').on('ended', function() {
jQuery("

Audio has already been play once. Please select a response.
").appendTo("#"+that+" .QuestionText");
});

Thanks rondev for the quickest reply I have ever seen! This works wonderfully. To modify this code, I try to center the message with "style="
jQuery('audio').on('play', function() { 
jQuery("

Audio has already been played once. Please select a response.
").appendTo("#"+that+
" .QuestionText");
But this gave me an Unexpected Identifier error.
Any work around?

Wrap text align part with single quotes
