<p>Kidney problems, sometimes requiring dialysis, have been reported.</p>
<p>Some people who take medicines called DPP-4 inhibitors like JANUVIA, may develop joint pain that can be severe. Call your doctor if you have severe joint pain.</p>
<p>If you take JANUVIA with another medicine that can cause low blood sugar (hypoglycemia), such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea medicine or insulin may need to be lowered while you use JANUVIA. Signs and symptoms of low blood sugar may include headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heart beat, sweating, and feeling jittery.</p>
<p>Your doctor may do blood tests before and during treatment with JANUVIA to see how well your kidneys are working. Based on these results, your doctor may change your dose of JANUVIA. The most common side effects of JANUVIA are upper respiratory tract infection, stuffy or runny nose and sore throat, and headache.</p>

要达到预期效果，请使用以下选项
if ($a.hasClass('active')) {
$(".minidiv").hide(); // this is not working****
$a.removeClass('active').siblings('.content').slideUp();
}
else {
$(".minidiv").show(); // this is not working****
$a.addClass('active').siblings('.content').slideDown();
} });
答案 1 :(得分：0)
你的$a即。 $(this)通常是<span class="sticky-close"><h2>[open]</h2></span>，而$(".minidiv", $a)正在.minidiv内搜索<span class="sticky-close"><h2>[open]</h2></span> $(".minidiv", $a).show();
内部$(".minidiv", $a.parent()).show();
，它将不会回馈任何内容。
替换
var accordion_head = $('.global_right_wrapper .stickySection-a .sticky-close');
accordion_head.on('click', function(event) {
var $a = $(this);
