====== Continue by Pressing a Key ======

Sometimes, the keyboard should be used: for instance, in laboratory studies for navigating the questionnaire or to exclude participants from a study for methodological reasons if they do not have a keyboard.

[[:en:create:javascript|JavaScript]] can directly react to inputs in the questionnaire and also to a keypress via the "keyup" event. The following HTML/JavaScript code hides the "Next" button but allows navigation to the next page by pressing the spacebar (keyCode 32).

<code html>
<script type="text/javascript">
// Hide the "Next" button
SoSciTools.submitButtonsHide();
// React to the "keyup" event
window.addEventListener("keyup", function(e) {
    if (e.keyCode == 32){
        SoSciTools.submitPage();
    }
});
</script>
</code>
