First off, that selector you use will only return you elements with the class .parentcheck which are actually checked. By definition, that means every element it returns (as it always returns a set in jQuery) will be checked, so if the element you're looking for isn't checked then it won't be in the set. Something like this might be what you're after:

if (! $(".parentcheck").is(":checked")) {
    $("#parent").hide();
}

I actually can't get your question, it should help you.

var $check = $('.parentCheck');
if ($check.val() == '' || toString($check.val()) == "0") {
    // do your stuff
}

if ($check.attr('checked')) {
    // checked, do your stuff
}
else { 
    // is not checked, do another stuff
}
