TypeError: $(...).parents(...).size is not a function
size() was deprecated years ago and removed in version 3 ... use length instead
if (e.target.id == "wrapper" || $(e.target).parents("#wrapper").length)
All you had to do was look this up in the size() docs to find this out
Please use 'length' like @charlietfl suggested. But I was unable to trace from where the error was getting displayed, hence I ended up with below.
(function ($) {
$.fn.extend({
size: function () {
return $(this).length;
}
});
})(jQuery);
