jQuery查找li元素直到，如果有nextUntil元素

Posted 2021-02-26

Catches click, if element has nextUntil elements, triggers a slideDown of child elements and returns false (to stop the anchor), if there are no nextUntil elements, does nothing and allows the click through (the anchor works).

$("li.par_cat").click(function() {
	var el_count = $(this).nextUntil("li.par_cat").size();
	if(el_count == 0){
		// I'll add something here later.
	}else{
	$(this).nextUntil("li.par_cat").each(function() {
		$(this).slideToggle("slow");
	});
	return false;
	}
});
