以下是我想要實(shí)現(xiàn)的目標(biāo) - 當(dāng)選擇導(dǎo)航欄中的下拉項(xiàng)時(shí)，完成以下兩個(gè)操作：轉(zhuǎn)到目標(biāo) id 的 div將導(dǎo)航欄卷起至初始狀態(tài)（將其隱藏回完全卷起的狀態(tài)）事實(shí)證明，我只能做到其中之一，但不能同時(shí)做到兩者。有人可以幫助指導(dǎo)我如何實(shí)現(xiàn)這兩點(diǎn)嗎？我相信第一個(gè)下拉項(xiàng)錨點(diǎn)應(yīng)該做到這一點(diǎn)，但是，由于某種原因，它在卷起導(dǎo)航欄后不會(huì)轉(zhuǎn)到 targetId。data-toggle="collapse"僅當(dāng)我刪除和 時(shí)，錨點(diǎn)才會(huì)帶我到達(dá)目標(biāo)data-target=".navbar-collapse.show"，這是第二個(gè)錨點(diǎn)顯示的內(nèi)容，但導(dǎo)航欄不會(huì)卷起。<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css"><nav class="navbar navbar-dark bg-dark fixed-top"> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarsExampleDefault"> <ul class="navbar-nav mr-auto"> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Menu</a> <div class="dropdown-menu shadow rounded" aria-labelledby="dropdown01"> <a class="dropdown-item" href="#targetId" data-toggle="collapse" data-target=".navbar-collapse.show">nav-link does get hidden, but it doesn't hit the target</a> <a class="dropdown-item" href="#targetId">Hits the target, but the nav-link does not get hidden</a> </div> </li> </ul> </div></nav><!-- navbar ends here --><div id="targetId">Content</div><script src="https://code.jquery.com/jquery-3.4.1.slim.min.js"></script><script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js"></script><script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js"></script>

你可以用Javascript它。
document.querySelectorAll('.custom_collapse').forEach(cur => {
cur.addEventListener('click', () => {
document.querySelector('.navbar_collapse').classList.remove('show');
});
});
#targetId {
/* JUST FOR SEE TARGET */
margin-top: 120vh;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">
<nav class="navbar navbar-dark bg-dark fixed-top">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse navbar_collapse" id="navbarsExampleDefault">
<ul class="navbar-nav mr-auto">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Menu</a>
<div class="dropdown-menu shadow rounded" aria-labelledby="dropdown01">
<a class="dropdown-item custom_collapse" href="#targetId">nav-link does get hidden, but it doesn't hit the target</a>
<a class="dropdown-item custom_collapse" href="#targetId">Hits the target, but the nav-link does not get hidden</a>
</div>
</li>
</ul>
</div>
</nav>
<!-- navbar ends here -->
<div id="targetId">Content</div>
