我想单独标记每个div的计数，但是它给出了全长。在我的情况下，我不想要全长我需要每个div标签计数。为了做到这一点，我每个人都使用jquery，但它给出了错误的数量，请有人帮助我..
如果标签数量大于5，我想加载+否则它应该隐藏。 HTML代码，
$('.list-group-item').each(function() {
var label_count = 0;
label_count = $(this).find('label').length;
alert(label_count);
// alert(label_count);
$(this).find('label:gt(4)').hide();
// count++;
if (label_count > 4) {
//alert(count);
$(".loadMore").show();
}
// else
// {
// $(".loadMore").show();
// }

答案 0 :(得分：3)
要解决此问题，首先需要限制选择器仅查找div类的.list-group-item元素。从那里你需要使用$(this).find('.loadMore')来获取当前标签集中的按钮，而不是一次影响所有标签。试试这个：
$('div.list-group-item').each(function() {
var $group = $(this);
var label_count = $group.find('label').length;
$group.find('label:gt(3)').hide();
$group.find(".loadMore").toggle(label_count > 4);
});.loadMore, .showLess { display: none; }<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

请注意，:gt选择器使用从零开始的元素索引，因此您需要使用:gt(3)来隐藏除前四个元素之外的所有元素。
