Kosalela yango

Na nzela ya ba attributs ya ba données to JavaScript, plugin oyo ezali kokita ebalusaka makambo oyo ebombami (ba menu oyo ezali kokita) na kobongola .showkelasi na moboti .dropdown-menu. Attribut data-bs-toggle="dropdown"etie motema mpo na kokanga ba menu ya kokita na niveau ya application, yango wana ezali likanisi malamu kosalela yango ntango nyonso.

Na ba appareils oyo ekoki ko toucher, kofungola dropdown ebakisi ba mouseoverhandlers ya pamba na bana ya mbala moko ya <body>élément. This admittedly ugly hack is necessary to work around a quirk in iOS’ event delegation , oyo soki te elingaki kopekisa robinet esika nyonso libanda ya dropdown e déclencher code oyo ekanga dropdown. Soki kaka dropdown ekangami, ba mouseoverhandlers oyo ya pamba ya kobakisa elongolamaka.

Na nzela ya ba attributs ya ba données

Bakisa data-bs-toggle="dropdown"na lien to na bouton mpo na kobongola esika oyo ezali kokita.

<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>

Na nzela ya JavaScript

Benga ba dropdowns na nzela ya JavaScript:

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

Indépendamment soki obengi dropdown na yo na nzela ya JavaScript to na esika na yango kosalela data-api, data-bs-toggle="dropdown"esengeli ntango nyonso kozala présent na élément déclencheur ya dropdown.

Makambo oyo okoki kopona

Ba options ekoki koleka na nzela ya ba attributs ya ba données to JavaScript. Mpo na ba attributs ya ba données, bakisa kombo ya option na data-bs-, lokola na data-bs-offset="". Sala makasi obongola lolenge ya cas ya kombo ya option uta camelCase na kebab-case tango ozali koleka ba options na nzela ya ba attributs ya ba données. Na ndakisa, na esika ya kosalela data-bs-autoClose="false", salelá data-bs-auto-close="false".

Nkombo Lolenge Mbeba Ndimbola
boundary molongo ya molongo | eloko 'clippingParents' Frontière ya contrainte ya débordement ya menu ya kokita (etali kaka modificateur ya preventOverflow ya Popper). Na ndenge ya libela ezali 'clippingParents'mpe ekoki kondima référence HTMLElement (na nzela ya JavaScript kaka). Mpo na koyeba makambo mingi tala Docs ya detectOverflow ya Popper .
reference molongo ya molongo | élément | moto ya likambo 'toggle' Elemento ya référence ya menu oyo ezali kokita. Endimi motuya ya 'toggle', 'parent', référence HTMLElement to eloko oyo epesaka getBoundingClientRect. Mpo na koyeba makambo mingi tala ba docs ya constructeur ya Popper mpe ba docs ya élément virtuel .
display shene 'dynamic' Par défaut, tosalelaka Popper pona positionnement dynamique. Désactiver oyo na static.
offset array ya | molongo ya molongo | mosala [0, 2]

Offset ya dropdown par rapport na cible na yango. Okoki koleka molongo na ba attributs ya ba données na ba valeurs oyo ekabwani na virgule lokola:data-bs-offset="10,20"

Tango fonction esalelami pona koyeba offset, ebengamaka na objet oyo ezali na placement ya popper, référence, na ba rects ya popper lokola argument na yango ya liboso. Node DOM ya élément déclencheur eleki lokola argument ya mibale. Fonction esengeli kozongisa array oyo ezali na ba nombres mibale: .[skidding, distance]

Mpo na koyeba makambo mingi tala Docs ya offset ya Popper .
autoClose boolean ya | shene true

Configurer comportement ya auto close ya dropdown:

  • true- esika ya kokita ekokangama na kofina libanda to na kati ya menu ya kokita.
  • false- déroulant ekokangama na kofina bouton toggle mpe kobenga manuellement hideto toggleméthode. (Lisusu ekokangama te na kofina esctouche)
  • 'inside'- esika ya kokita ekokangama (kaka) na kofina na kati ya menu ya kokita.

popperConfig null | eloko | mosala null

Mpo na kobongola configuration ya Popper ya liboso ya Bootstrap, tala configuration ya Popper .

Tango fonction moko esalelami pona kosala configuration ya Popper, ebengami na objet oyo ezali na configuration ya Popper par défaut ya Bootstrap. Esalisaka yo osalela mpe osangisa oyo ya liboso na configuration na yo moko. Fonction esengeli kozongisa objet ya configuration pona Popper.

Kosalela fonction napopperConfig

var dropdown = new bootstrap.Dropdown(element, {
  popperConfig: function (defaultBsPopperConfig) {
    // var newPopperConfig = {...}
    // use defaultBsPopperConfig if needed...
    // return newPopperConfig
  }
})

Ba méthodes ya kosala
