Hoopiha a hoapono

E hoʻoikaika i kāu .navmau mea e hoʻonui i ka laula piha i loaʻa i hoʻokahi o nā papa hoʻololi ʻelua. No ka hoʻopiha piha ʻana i nā wahi āpau i loaʻa me kāu .nav-items, e hoʻohana i ka .nav-fill. E hoʻomaopopo i ka noho ʻana o nā wahi ākea āpau, akā ʻaʻole like ka laulā o kēlā me kēia mea nav.

  <a class="nav-link" href="#">Much longer nav link</a>
  <a class="nav-link" href="#">Link</a>

No nā mea like-ākea, hoʻohana .nav-justified. E noho ʻia nā wahi ākea āpau e nā loulou nav, akā ʻaʻole e like me ka mea i .nav-fillluna, e like ka laulā o kēlā me kēia mea nav.

Ma o JavaScript

E hoʻā i nā ʻaoʻao papa ma o JavaScript (pono e hoʻāla ʻia kēlā me kēia ʻaoʻao):

var triggerTabList = [].slice.call(document.querySelectorAll('#myTab button'))
triggerTabList.forEach(function (triggerEl) {
  var tabTrigger = new bootstrap.Tab(triggerEl)

  triggerEl.addEventListener('click', function (event) {
    event.preventDefault()
    tabTrigger.show()
  })
})

Hiki iā ʻoe ke hoʻāla i nā pā pākahi ma nā ʻano he nui:

var triggerEl = document.querySelector('#myTab button[data-bs-target="#profile"]')
bootstrap.Tab.getInstance(triggerEl).show() // Select tab by name

var triggerFirstTabEl = document.querySelector('#myTab li:first-child button')
bootstrap.Tab.getInstance(triggerFirstTabEl).show() // Select first tab

Ka hopena mae

No ka hoʻopau ʻana i nā tabs, hoʻohui .fadei kēlā me kēia .tab-pane. Pono ka pane ʻaoʻao mua e ʻike .showi ka ʻike mua.

<div class="tab-content">
  <div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
  <div class="tab-pane fade" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
  <div class="tab-pane fade" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
</div>

Nā ʻano hana

Nā ʻano asynchronous a me nā hoʻololi

Asynchronous nā ala API āpau a hoʻomaka i kahi hoʻololi . Hoʻi lākou i ka mea kelepona i ka wā e hoʻomaka ai ka hoʻololi akā ma mua o ka pau ʻana . Eia kekahi, e nānā ʻole ʻia kahi ala e kāhea ai i kahi mea hoʻololi .

E ʻike i kā mākou palapala JavaScript no ka ʻike hou aku .

constructor

Ho'ā i ka ʻeleʻele tab a me ka ipu maʻiʻo. Pono ka Tab i kahi a i data-bs-targetʻole, inā e hoʻohana ana i kahi loulou, kahi hrefhiʻohiʻona, e huli ana i kahi pahu pahu i ka DOM.

hōʻike

Koho i ka pā i hāʻawi ʻia a hōʻike i kāna pane pili. ʻAʻole i koho ʻia kekahi ʻaoʻao ʻē aʻe i koho mua ʻia a hūnā ʻia kāna pane pili. E hoʻi i ka mea kelepona ma mua o ka hōʻike ʻia ʻana o ka pane tab (ʻo ia hoʻi ma mua o ka hiki ʻana o ka shown.bs.tabhanana).

  var someTabTriggerEl = document.querySelector('#someTabTrigger')
  var tab = new bootstrap.Tab(someTabTriggerEl)

  tab.show()

e hoolei aku

Hoʻopau i ka ʻaoʻao o kahi mea.

getInstance

ʻO ke ala static e hiki ai iā ʻoe ke kiʻi i ka laʻana tab i pili me kahi mea DOM

var triggerEl = document.querySelector('#trigger')
var tab = bootstrap.Tab.getInstance(triggerEl) // Returns a Bootstrap tab instance

getOrCreateInstance

ʻO ke ala static e hiki ai iā ʻoe ke kiʻi i ka laʻana tab i pili me kahi mea DOM, a i ʻole e hana i kahi mea hou inā ʻaʻole i hoʻomaka ʻia.

var triggerEl = document.querySelector('#trigger')
var tab = bootstrap.Tab.getOrCreateInstance(triggerEl) // Returns a Bootstrap tab instance

Nā hanana

I ka hōʻike ʻana i kahi ʻaoʻao hou, e ʻā nā hanana ma ke ʻano penei:

hide.bs.tab(ma ka papa hana o kēia manawa)
show.bs.tab(ma ka ʻaoʻao e hōʻike ʻia)
hidden.bs.tab(ma ka papa hana mua, e like me ka hide.bs.tabhanana)
shown.bs.tab(ma ka ʻaoʻao hou i hōʻike ʻia, e like me ka show.bs.tabhanana)

Inā ʻaʻohe papa i hana mua ʻia, ʻaʻole e puhi ʻia nā hanana hide.bs.taba me nā hanana.hidden.bs.tab

ʻAno hanana	wehewehe
`show.bs.tab`	Hoʻomaka kēia hanana ma ka hōʻike pā, akā ma mua o ka hōʻike ʻia ʻana o ka pā hou. E hoʻohana `event.target`a `event.relatedTarget`e hoʻopaʻa i ka pā hana a me ka pā hana mua (inā loaʻa) kēlā me kēia.
`shown.bs.tab`	Hoʻomaka kēia hanana ma ka hōʻike pā ma hope o ka hōʻike ʻia ʻana o kahi pā. E hoʻohana `event.target`a `event.relatedTarget`e hoʻopaʻa i ka pā hana a me ka pā hana mua (inā loaʻa) kēlā me kēia.
`hide.bs.tab`	Ke ahi kēia hanana i ka wā e hōʻike ʻia ai kahi pā hou (a no laila e hūnā ʻia ka pā hana mua). E hoʻohana `event.target`a `event.relatedTarget`e hoʻopaʻa i ka ʻaoʻao ʻeleu o kēia manawa a me ka ʻaoʻao koke-e-ʻeleu hou.
`hidden.bs.tab`	Ke ahi kēia hanana ma hope o ka hōʻike ʻia ʻana o kahi pā hou (a no laila ua hūnā ʻia ka pā hana mua). E hoʻohana `event.target`a `event.relatedTarget`e hoʻopaʻa i ka papa hana mua a me ka pā hana hou.

var tabEl = document.querySelector('button[data-bs-toggle="tab"]')
