Lub hauv paus .navtivthaiv tsis suav nrog ib .activelub xeev. Cov piv txwv hauv qab no suav nrog cov chav kawm, feem ntau yog ua kom pom tias chav kawm tshwj xeeb no tsis ua rau muaj qhov tshwj xeeb styling.

Txhawm rau qhia lub xeev nquag mus rau kev pabcuam thev naus laus zis, siv tus aria-currentcwj pwm - siv tus pagenqi rau nplooj ntawv tam sim no, lossis truerau cov khoom tam sim no hauv ib txheej.

<ul class="nav">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>

  </li>
  <li class="nav-item">
    <a class="nav-link disabled">Disabled</a>
  </li>
</ul>

Raws li ib txwm muaj, ntsug navigation yog ua tau yam tsis muaj <ul>s, ib yam nkaus.

<nav class="nav flex-column">

  <a class="nav-link disabled">Disabled</a>
</nav>

Tabs

Siv qhov yooj yim nav los ntawm saum toj no thiab ntxiv cov .nav-tabschav kawm los tsim ib lub tabbed interface. Siv lawv los tsim cov cheeb tsam tabbable nrog peb tab JavaScript plugin .

<ul class="nav nav-tabs">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">

  </li>
  <li class="nav-item">
    <a class="nav-link disabled">Disabled</a>
  </li>
</ul>

Cov tshuaj

Siv tib yam HTML, tab sis siv .nav-pillshloov:

<ul class="nav nav-pills">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>

  </li>
  <li class="nav-item">
    <a class="nav-link disabled">Disabled</a>
  </li>
</ul>

Sau thiab ua pov thawj

quab yuam koj .navcov ntsiab lus txuas ntxiv qhov dav muaj nyob hauv ib qho ntawm ob chav hloov kho. Yuav kom proportionately sau tag nrho cov chaw muaj nrog koj .nav-items, siv .nav-fill. Daim ntawv ceeb toom tias txhua qhov chaw kab rov tav yog nyob, tab sis tsis yog txhua qhov khoom nav muaj qhov dav tib yam.

<ul class="nav nav-pills nav-fill">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Much longer nav link</a>

    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled">Disabled</a>
  </li>
</ul>

Thaum siv ib <nav>-raws li kev taw qhia, koj tuaj yeem ua kom nyab xeeb tshem tawm .nav-itemraws li tsuas .nav-linkyog xav tau rau cov ntsiab lus styling <a>.

<nav class="nav nav-pills nav-fill">
  <a class="nav-link active" aria-current="page" href="#">Active</a>
  <a class="nav-link" href="#">Much longer nav link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled">Disabled</a>
</nav>

Rau qhov sib npaug-dav, siv .nav-justified. Txhua qhov chaw kab rov tav yuav nyob ntawm qhov txuas nav, tab sis tsis zoo li cov .nav-fillsaum toj no, txhua yam khoom nav yuav yog tib qhov dav.

<ul class="nav nav-pills nav-justified">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>

  <a class="nav-link disabled">Disabled</a>
</nav>

Ua haujlwm nrog flex utilities

Yog tias koj xav tau cov kev hloov pauv hloov pauv, xav txog kev siv cov khoom siv hluav taws xob flexbox . Thaum hais lus ntau dua, cov khoom siv no muab kev hloov kho ntau dua hla cov ntsiab lus teb. Hauv qhov piv txwv hauv qab no, peb cov nav hia yuav muab tso rau ntawm qhov chaw qis tshaj plaws, tom qab ntawd hloov mus rau kab rov tav layout uas sau qhov dav muaj pib los ntawm qhov chaw me me.

<nav class="nav nav-pills flex-column flex-sm-row">
  <a class="flex-sm-fill text-sm-center nav-link active" aria-current="page" href="#">Active</a>

Nco ntsoov tias cov bars navigation, txawm tias pom kev zoo li tabs nrog cov .nav-tabschav kawm, yuav tsum tsis txhob muab role="tablist", role="tab"lossis role="tabpanel"cov cwj pwm. Cov no tsuas yog tsim nyog rau dynamic tabbed interfaces, raws li tau piav qhia hauv WAI ARIA Authoring Practices . Saib JavaScript tus cwj pwm rau dynamic tabbed interfaces hauv seem no piv txwv. Tus aria-currentcwj pwm tsis tsim nyog ntawm dynamic tabbed interfaces txij li peb JavaScript tswj hwm lub xeev xaiv los ntawm kev ntxiv aria-selected="true"rau ntawm lub tab nquag.

Siv cov dropdowns

Ntxiv dropdown menus nrog me ntsis ntxiv HTML thiab dropdowns JavaScript plugin .

Tabs nrog dropdowns

<ul class="nav nav-tabs">

JavaScript cwj pwm

Siv lub tab JavaScript plugin - suav nrog nws tus kheej lossis los ntawm cov ntaub ntawv sau ua ke bootstrap.js- txhawm rau txuas ntxiv peb cov tab thiab cov ntsiav tshuaj los tsim cov tabbable panes ntawm cov ntsiab lus hauv zos.

Dynamic tabbed interfaces, raws li tau piav qhia hauv WAI ARIA Authoring Practices , xav tau role="tablist", role="tab", role="tabpanel", thiab cov aria-cwj pwm ntxiv txhawm rau txhawm rau nthuav qhia lawv cov qauv, kev ua haujlwm thiab lub xeev tam sim no rau cov neeg siv cov thev naus laus zis pab (xws li cov nyeem ntawv tshuaj ntsuam). Raws li qhov kev coj ua zoo tshaj plaws, peb pom zoo kom siv <button>cov ntsiab lus rau cov tabs, vim tias cov no yog cov kev tswj hwm uas ua rau muaj kev hloov pauv hloov pauv, tsis yog cov txuas uas mus rau nplooj ntawv tshiab lossis qhov chaw.

Nco ntsoov tias dynamic tabbed interfaces yuav tsum tsis muaj dropdown menus, vim qhov no ua rau ob qho tib si usability thiab accessibility teeb meem. Los ntawm kev pom kev siv tau, qhov tseeb tias tam sim no tab tom nthuav tawm lub ntsiab lus tsis pom tam sim ntawd (raws li nws nyob hauv cov ntawv qhia zaub mov kaw) tuaj yeem ua rau tsis meej pem. Los ntawm qhov kev nkag mus tau zoo, tam sim no tsis muaj txoj hauv kev zoo los piav qhia qhov kev tsim kho no rau tus qauv WAI ARIA tus qauv, txhais tau tias nws tsis tuaj yeem nkag siab yooj yim rau cov neeg siv cov cuab yeej pabcuam.

Nov yog qee qhov chaw muab cov ntsiab lus hauv Tsev tab cov ntsiab lus cuam tshuam. Nyem rau lwm tab yuav toggle qhov pom ntawm qhov no rau lwm qhov. Lub tab JavaScript swaps chav kawm los tswj cov ntsiab lus pom pom thiab styling. Koj tuaj yeem siv nws nrog tabs, ntsiav tshuaj, thiab lwm yam .nav-powered navigation.

Ntawm JavaScript

Qhib tabbable tabs ntawm JavaScript (txhua tab yuav tsum tau qhib ib tus zuj zus):

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()
  })
})

Koj tuaj yeem qhib ib tus neeg tab hauv ntau txoj hauv kev:

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

Fade nyhuv

Txhawm rau ua kom cov tabs ploj mus, ntxiv .faderau txhua qhov .tab-pane. Thawj tab pane yuav tsum tau .showua kom pom cov ntsiab lus thawj zaug.

<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>

constructor

Activates lub tab element thiab cov ntsiab lus ntim. Tab yuav tsum muaj ib data-bs-targetlossis, yog siv qhov txuas, tus hrefcwj pwm, tsom rau lub thawv ntawm DOM.

<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item" role="presentation">
    <button class="nav-link active" id="home-tab" data-bs-toggle="tab" data-bs-target="#home" type="button" role="tab" aria-controls="home" aria-selected="true">Home</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="profile-tab" data-bs-toggle="tab" data-bs-target="#profile" type="button" role="tab" aria-controls="profile" aria-selected="false">Profile</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="messages-tab" data-bs-toggle="tab" data-bs-target="#messages" type="button" role="tab" aria-controls="messages" aria-selected="false">Messages</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="settings-tab" data-bs-toggle="tab" data-bs-target="#settings" type="button" role="tab" aria-controls="settings" aria-selected="false">Settings</button>
  </li>
</ul>

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

<script>
  var firstTabEl = document.querySelector('#myTab li:last-child button')
  var firstTab = new bootstrap.Tab(firstTabEl)

  firstTab.show()
</script>

ua yeeb yam

Xaiv qhov muab tab thiab qhia nws cov kab sib txuas. Lwm lub tab uas tau xaiv yav dhau los yuav tsis raug xaiv thiab nws cov pane cuam tshuam tau muab zais. Rov qab mus rau tus neeg hu ua ntej lub tab pane tau tshwm sim tiag tiag (piv txwv li ua ntej qhov shown.bs.tabxwm txheej tshwm sim).

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

  tab.show()

pov tseg

Ua kom puas lub ntsiab tab.

getInstance

Txoj kev zoo li qub uas tso cai rau koj kom tau txais tab piv txwv cuam tshuam nrog DOM lub caij

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

getOrCreateInstance

Txoj kev zoo li qub uas tso cai rau koj kom tau txais tab piv txwv cuam tshuam nrog DOM lub caij, lossis tsim ib qho tshiab yog tias nws tsis tau pib

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

Cov xwm txheej

Thaum pom ib lub tab tshiab, cov xwm txheej hluav taws kub hauv qhov kev txiav txim hauv qab no:

hide.bs.tab(ntawm lub tab active tam sim no)
show.bs.tab(ntawm qhov yuav tsum tau qhia tab)
hidden.bs.tab(nyob rau yav dhau los active tab, tib yam li rau qhov hide.bs.tabkev tshwm sim)
shown.bs.tab(ntawm lub tab tshiab uas nyuam qhuav tshwm sim, tib yam li rau qhov show.bs.tabkev tshwm sim)

Yog tias tsis muaj tab twb ua haujlwm lawm, ces cov xwm txheej hide.bs.tabthiab hidden.bs.tabcov xwm txheej yuav tsis raug rho tawm haujlwm.

Hom xwm txheej	Kev piav qhia
`show.bs.tab`	Qhov kev tshwm sim no tua hluav taws ntawm tab qhia, tab sis ua ntej tab tshiab tau tshwm sim. Siv `event.target`thiab `event.relatedTarget`tsom rau lub tab active thiab yav dhau los active tab (yog tias muaj) feem.
`shown.bs.tab`	Qhov kev tshwm sim no tua hluav taws ntawm tab qhia tom qab tau pom tab. Siv `event.target`thiab `event.relatedTarget`tsom rau lub tab active thiab yav dhau los active tab (yog tias muaj) feem.
`hide.bs.tab`	Qhov kev tshwm sim no tua hluav taws thaum lub tab tshiab yuav tsum tau tshwm sim (thiab yog li lub tab yav dhau los yuav tsum tau muab zais). Siv `event.target`thiab `event.relatedTarget`tsom rau cov tab tam sim no thiab cov tshiab sai sai-rau-yuav-ua haujlwm tab, feem.
`hidden.bs.tab`	Qhov kev tshwm sim no tshwm sim tom qab lub tab tshiab tau tshwm sim (thiab yog li lub tab active yav dhau los tau muab zais). Siv `event.target`thiab `event.relatedTarget`tsom mus rau lub tab active yav dhau los thiab cov tshiab tab tshiab, raws li.

var tabEl = document.querySelector('button[data-bs-toggle="tab"]')
tabEl.addEventListener('shown.bs.tab', function (event) {
  event.target // newly activated tab
  event.relatedTarget // previous active tab
})
