Registering key-presses

Post your current script.

I've found three scripts on the internet. None of them worked. Script 1 Qualtrics.SurveyEngine.addOnload(function() { if ($('NextButton')) $('NextButton').hide(); if ($('PreviousButton')) $('PreviousButton').hide(); var that = this; Event.observe(document,'keydown',function(e){ var choiceID = null; if (e.keyCode == 76) //'l' was pressed { choiceID = 1; } else if (e.keyCode == 72) //'h' was pressed { choiceID = 2; } if (choiceID) { that.setChoiceValue(choiceID,true); that.clickNextButton(); } }); }); Script 2 Qualtrics.SurveyEngine.addOnload(function() { this.hideNextButton(); this.hidePreviousButton(); var that = this; Event.observe(document, 'keydown', function keydownCallback(e) { var choiceID = null; switch (e.keyCode) { case 72: // 'h' was pressed choiceID = 1; break; case 76: // 'l' was pressed choiceID = 2; break; } if (choiceID) { Qualtrics.SurveyEngine.setEmbeddedData("choiceID",choiceID); Event.stopObserving(document, 'keydown', keydownCallback); that.setChoiceValue(choiceID, true); that.clickNextButton(); } }); }); Script 3 Qualtrics.SurveyEngine.addOnload(function() { this.hideNextButton(); this.hidePreviousButton(); var that = this; Event.observe(document, 'keydown', function keydownCallback(e) { var choiceID = null; switch (e.keyCode) { case 74: // 'j' was pressed choiceID = 1; break; case 75: // 'k' was pressed choiceID = 2; break; } if (choiceID) { Event.stopObserving(document, 'keydown', keydownCallback); that.setChoiceValue(choiceID, true); that.clickNextButton(); } }); });

Try changing addOnload to addOnReady.

changing addOnload to addOnReady had no effect on registration of key-presses. Do you have another suggestion?

Are you in preview mode? If so, you have to click in the desktop window first.

No i'm not in review mode, I've distributed and completed the survey by anonymous link.

@LaurenK, Thank you for your latest response. Unfortunately, also the scripts mentioned in the links in your response does not register responses (the second link does not even let me proceed to the next page). I'm still struggling with this puzzle, any help is appreciated.

@TomG I've tried the three scripts I mentioned in my post on June 2, unfortunately none of them worked.

Lauren is correct, the JavaScript I wrote for Left and Right arrow keys will work here: https://gist.github.com/mattbloomfield/e35b360fb259df583e17020abcec4ca9 You need to change the key mappings though. Your browser listens for key presses and there is a numeric code associated with each key, as shown here: http://keycode.info/ Working Example: https://qualtricssfi.az1.qualtrics.com/jfe/preview/SV_6KzTr6Nr0UfPJSl?Q_SurveyVersionID=current&Q_CHL=preview .qsf attached -- and as Lauren pointed out, in Preview you do have to click the survey for it to register clicks. This is because it is iFramed in rather than presented as the main scope.

@mattyb513 just wanted to say that your code works for me. Thank you. This example made it simple to learn how to get keyboard responses.

@mattyb513, @PsychSurvey, @LaurenK, @TomG, thank you very much for your help!! The script provided by mattyb513 works for me too :) Again thanks a lot for your help. Much appreciated!
