FAQs div中的jquery slideUp按钮

Question

我的脚本效果很好：

＆＃13;

＆＃13;

$(document).ready(function() {
  $('#faqs li').each(function() {
    var tis = $(this),
      state = false,
      answer = tis.next('div').hide().css('height', 'auto').slideUp();
    tis.click(function() {
      state = !state;
      answer.slideToggle(state);
      tis.toggleClass('active', state);
    });
  });
});

＆＃13;

#faqs h3 {
  cursor: pointer;
}
#faqs li.active {
  color: #d74646;
}
#faqs div {
  height: 0;
  overflow: hidden;
  position: relative;
}
#faqs div p {
  padding: 0;
  margin-bottom: 15px;
}
.slideup:hover {
  color: blue;
  cursor: pointer
}

＆＃13;
