jQuery: Check for next element, if not hide

I have some H3 elements that sometimes are followed by a P element. I would like to check and see if the next element after the h3 is a p, and if not, hid开发者_运维知识库e that h3.

$('h3').each(function(n, e) {
    $(e).next().is('p') || $(e).hide();
});

$('h3').filter(function() { return !$(this).next().is('p') }).hide();
