A Validation Error resfreshes the page and JavaScript won't execute. Why?
I use this code in JavaScript to hide the PreviousButton on a page:
Qualtrics.SurveyEngine.addOnload(function() {
jQuery("input#PreviousButton.PreviousButton.Button").css("display", "none");
});
I use this code on the first question of the block, no page break, and put it in addOnload, addOnready, addOnunload.
However, one of the question has a validation parameter. When this validation is not met and the NextButton is pressed, the page reloads and the PreviousButton is back.
Why is that so and how to fix it?

I had a similar problem but fixed it (albeit in a hacky way) by putting the code inside a timer

I think your code is too complicated :)
Try this:
Qualtrics.SurveyEngine.addOnReady(function()
{
$('PreviousButton').hide();
});

jQueryin place of
$as
$is a reserved token. Ref
