Tšhomišo

Ka dika tša datha goba JavaScript, polaka ya go theoga e fetoša diteng tše di utilwego (dimenu tša go theoga) ka go fetoša .showsehlopha go motswadi .dropdown-menu. Sebopego data-bs-toggle="dropdown"se ithekgile ka go tswalela dimenu tša go theoga maemong a tirišo, ka fao ke kgopolo ye botse go se šomiša ka mehla.

Ka didirišwa tše di kgontšhitšwego ka go kgoma, go bula go theoga go tlaleletša mouseoverditshwaro tše di se nago selo go bana ba kgauswi ba <body>elemente. This admittedly ugly hack is necessary to work around a quirk in iOS’ event delegation , e leng ka tsela e nngwe e ne e tla thibela pompo kae kapa kae ka ntle ho dropdown ho qholotsa khoutu e koala dropdown. Ge go šetše go tswaletšwe, didirišwa tše tša tlaleletšo tše di se nago selo mouseoverdi a tlošwa.

Ka dika ya data

Oketša data-bs-toggle="dropdown"go kgokagano goba konope go fetoša go theoga.

<div class="dropdown">
  <button id="dLabel" type="button" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown trigger
  </button>
  <ul class="dropdown-menu" aria-labelledby="dLabel">
    ...
  </ul>
</div>

Ka JavaScript

Bitša di-drolodown ka JavaScript:

var dropdownElementList = [].slice.call(document.querySelectorAll('.dropdown-toggle'))
var dropdownList = dropdownElementList.map(function (dropdownToggleEl) {
  return new bootstrap.Dropdown(dropdownToggleEl)
})
data-bs-toggle="dropdown"e sa dutše e nyakega

Go sa šetšwe gore o bitša dropdown ya gago ka JavaScript goba go e na le moo o diriša data-api, data-bs-toggle="dropdown"go nyakega ka mehla go ba gona go elemente ya go hlohleletša ya dropdown.

Dikgetho

Dikgetho di ka fetišwa ka dika tša datha goba JavaScript. Bakeng sa dika tša datha, tlaleletša leina la kgetho go data-bs-, bjalo ka go data-bs-offset="". Kgonthiša gore o fetoša mohuta wa molato wa leina la kgetho go tšwa go camelCase go ya go kebab-case ge o fetiša dikgetho ka dika tša datha. Ka mohlala, go e na le go diriša data-bs-autoClose="false", diriša data-bs-auto-close="false".
