Okuqukethwe kwangaphandle

Kwesinye isikhathi ufuna ukusebenzisa i-plugin yokugoqa ukuze uqalise isici sesiqukathi sokuqukethwe okuhlala ngaphandle kwe- .navbar. Ngoba i-plugin yethu isebenza ekufaniseni idnasekufaniseni data-bs-target, lokho kwenziwa kalula!

<div class="collapse" id="navbarToggleExternalContent">
  <div class="bg-dark p-4">
    <h5 class="text-white h4">Collapsed content</h5>
    <span class="text-muted">Toggleable via the navbar brand.</span>
  </div>
</div>
<nav class="navbar navbar-dark bg-dark">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>

Uma wenza lokhu, sincoma ukuthi ufake i-JavaScript eyengeziwe ukuze uhambise ukugxila ngokohlelo kusiqukathi uma sivulwa. Uma kungenjalo, abasebenzisi bekhibhodi nabasebenzisi bobuchwepheshe obusizayo bazoba nobunzima bokuthola okuqukethwe okusha okuveziwe - ikakhulukazi uma isiqukathi esivuliwe siza ngaphambi komguquli esakhiweni sedokhumenti. Futhi sincoma ukuthi wenze isiqiniseko sokuthi isiguquli sinesibaluli aria-controls, esikhomba idesiqukathi sokuqukethwe. Ngokombono, lokhu kuvumela abasebenzisi bobuchwepheshe obusizayo ukuthi bagxume ngokuqondile ukusuka kusiguquli baye esitsheni esisilawulayo–kodwa usekelo lwalokhu okwamanje alunalutho.
