Hi there,



I am trying to set up a multiple choice question with two answer options that does the following things:



1. The time it takes the respondent to make a decision is recorded (I do this by adding a timing question)

2. Instead of using the mouse, I want respondents to use either of two designated keys on the keyboard to log their response

3. The respondent should then advance automatically to the next question/block once they made a decision





I found some code that should do exactly that (see below). However - for some reason I don't understand - it does the following things instead:



1. I need to select an answer with the mouse. Thus, pressing j or k in order to select an answer doesn't do the trick.

2. However, once I selected an answer with the mouse and I press either j or k, I do advance to the next question.





What could be going wrong here and how can I fix it? Thanks so much in advance!



Theresa

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();

}

});

});
