I-Navs

Amadokhumenti nezibonelo zokuthi zisetshenziswa kanjani izingxenye ze-Bootstrap zokuzulazula ezifakiwe.

Isisekelo nav

Ukuzulazula kutholakala ku-Bootstrap yabelana ngemakhaphu evamile nezitayela, kusukela kusigaba sesisekelo .navkuya ezifundazweni ezisebenzayo nezikhubazekile. Shintshanisa amakilasi okushintsha ukuze ushintshe phakathi kwesitayela ngasinye.

Ingxenye yesisekelo .navyakhiwe nge-flexbox futhi inikeza isisekelo esiqinile sokwakha zonke izinhlobo zezingxenye zokuzulazula. Kubandakanya ukubhala ngaphezulu kwesitayela esithile (sokusebenza ngezinhlu), ezinye izixhumanisi zokunamathisela izindawo ezinkulu ezishaywayo, kanye nesitayela esiyisisekelo esikhubazekile.

Ingxenye yesisekelo .navayifaki noma yisiphi .activeisimo. Izibonelo ezilandelayo zifaka ikilasi, ikakhulukazi ukukhombisa ukuthi lesi sigaba asibangeli isitayela esikhethekile.

<ul class="nav">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Amakilasi asetshenziswa kulo lonke, ngakho umaki wakho ungaguquguquka kakhulu. Sebenzisa u <ul>-s njengangenhla, <ol>uma ukuhleleka kwezinto zakho kubalulekile, noma gingqa eyakho ngento <nav>. Ngoba .navukusetshenziswa display: flex, izixhumanisi ze-nav ziziphatha ngendlela efanayo nezinto ze-nav, kodwa ngaphandle kwemakhaphu eyengeziwe.

<nav class="nav">
  <a class="nav-link active" href="#">Active</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Izitayela ezitholakalayo

Shintsha isitayela sengxenye ye- .navs ngezilungisi kanye nezinsiza. Hlanganisa futhi ufanise njengoba kudingeka, noma wakhe owakho.

Ukuqondanisa okuvundlile

Shintsha ukuqondanisa okuvundlile kwe-nav yakho nezinsiza ze- flexbox . Ngokuzenzakalelayo, ama-navs aqondaniswe kwesokunxele, kodwa ungakwazi ukuwashintsha kalula ukuze aqondaniswe maphakathi noma kwesokudla.

Kuphakathi kokuthi .justify-content-center:

<ul class="nav justify-content-center">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Iqondaniswe kwesokudla ne- .justify-content-end:

<ul class="nav justify-content-end">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Iqondile

Beka ukuzulazula kwakho ngokushintsha isiqondiso sento eguquguqukayo ngohlelo .flex-columnlokusebenza. Udinga ukuwabeka kwezinye izindawo zokubuka kodwa hhayi kwezinye? Sebenzisa izinguqulo eziphendulayo (isb, .flex-sm-column).

<ul class="nav flex-column">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Njengenjwayelo, ukuzulazula okuqondile kungenzeka ngaphandle <ul>kuka-s, futhi.

<nav class="nav flex-column">
  <a class="nav-link active" href="#">Active</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Amathebhu

Ithatha i-nav eyisisekelo kusuka phezulu futhi yengeza .nav-tabsiklasi ukuze ikhiqize isixhumi esibonakalayo esinamathebhu. Zisebenzise ukuze udale izifunda ezithintekayo ngethebhu yethu i- JavaScript plugin .

<ul class="nav nav-tabs">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Amaphilisi

Thatha leyo HTML efanayo, kodwa sebenzisa .nav-pillsesikhundleni salokho:

<ul class="nav nav-pills">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Gcwalisa futhi ubeke izizathu

Phoqa .navokuqukethwe kwakho ukunweba ububanzi obugcwele obutholakalayo izigaba ezimbili zesilungisi. Ukuze ugcwalise ngokulinganayo zonke izikhala ezitholakalayo nge- .nav-items yakho, sebenzisa .nav-fill. Qaphela ukuthi sonke isikhala esivundlile sigcwele, kodwa akuzona zonke izinto ze-nav ezinobubanzi obufanayo.

<ul class="nav nav-pills nav-fill">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Much longer nav link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Uma usebenzisa <nav>ukuzulazula okusekelwe, qiniseka ukuthi ufaka phakathi .nav-itemkwamahange.

<nav class="nav nav-pills nav-fill">
  <a class="nav-item nav-link active" href="#">Active</a>
  <a class="nav-item nav-link" href="#">Much longer nav link</a>
  <a class="nav-item nav-link" href="#">Link</a>
  <a class="nav-item nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Ukuze uthole ama-elementi anobubanzi obulinganayo, sebenzisa .nav-justified. Sonke isikhala esivundlile sizosetshenziswa izixhumanisi ze-nav, kodwa ngokungafani nalokhu .nav-fillokungenhla, yonke into ye-nav izoba nobubanzi obufanayo.

<ul class="nav nav-pills nav-justified">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Much longer nav link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Ngokufanayo .nav-fillnesibonelo sokusebenzisa <nav>ukuzulazula okusekelwe, qiniseka ukuthi ufaka phakathi .nav-itemkwamahange.

<nav class="nav nav-pills nav-justified">
  <a class="nav-item nav-link active" href="#">Active</a>
  <a class="nav-item nav-link" href="#">Much longer nav link</a>
  <a class="nav-item nav-link" href="#">Link</a>
  <a class="nav-item nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Ukusebenza ngezinsiza eziguqukayo

Uma udinga ukuhlukahluka okusabelayo kwe-nav, cabanga ukusebenzisa uchungechunge lwezinsiza ze- flexbox . Ngenkathi i-verbose kakhudlwana, lezi zinsiza zinikeza ukwenza ngokwezifiso okukhulu kuwo wonke ama-breakpoints asabelayo. Esibonelweni esingezansi, i-nav yethu izopakishwa endaweni yokuphumula ephansi kakhulu, bese ijwayelana nesakhiwo esivundlile esigcwalisa ububanzi obutholakalayo kusukela endaweni encane yokuhlukana.

<nav class="nav nav-pills flex-column flex-sm-row">
  <a class="flex-sm-fill text-sm-center nav-link active" href="#">Active</a>
  <a class="flex-sm-fill text-sm-center nav-link" href="#">Longer nav link</a>
  <a class="flex-sm-fill text-sm-center nav-link" href="#">Link</a>
  <a class="flex-sm-fill text-sm-center nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Mayelana nokufinyeleleka

Uma usebenzisa i-navs ukuze unikeze ibha yokuzulazula, qiniseka ukuthi ungeza u-a role="navigation"esiqukathi esinengqondo kunazo zonke esingumzali se- <ul>, noma usonge into ethile kukho <nav>konke ukuzulazula. Ungangezi indima <ul>kuyona uqobo, njengoba lokhu kuzoyivimbela ukuthi imenyezelwe njengohlu lwangempela ngobuchwepheshe obusizayo.

Qaphela ukuthi amabha okuzulazula, ngisho noma enziwe isitayela njengamathebhu anesigaba .nav-tabs, akufanele anikezwe , role="tablist"noma role="tab"izibaluli role="tabpanel". Lokhu kulungele kuphela ukuxhumana kwamathebhu ashukumisayo, njengoba kuchazwe ku- WAI ARIA Imikhuba Yokugunyaza . Bona impatho ye-JavaScript yezindawo zokusebenzelana zamathebhu ashukumisayo kulesi sigaba njengesibonelo.

Ukusebenzisa okwehliswayo

Engeza amamenyu okwehlayo nge-HTML encane eyengeziwe kanye ne- plugin ye-JavaScript eyehlayo .

Amathebhu anokwehliswayo

<ul class="nav nav-tabs">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item dropdown">
    <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
    <div class="dropdown-menu">

  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Amaphilisi ane dropdowns

<ul class="nav nav-pills">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item dropdown">
    <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>

    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Ukuziphatha kweJavaScript

Sebenzisa i-plugin yethebhu ye-JavaScript—ifake ngayodwa noma ngefayela elihlanganisiwe bootstrap.js—ukuze unwebe amathebhu ethu okuzulazula namaphilisi ukuze udale amafasitelana aphathekayo wokuqukethwe kwasendaweni, ngisho nangamamenyu okwehlayo.

Uma wakha i-JavaScript yethu ngomthombo, idingautil.js .

Izixhumi ezibonakalayo ezinamathebhu anamandla, njengoba kuchazwe ku- WAI ARIA Imikhuba Yokugunyaza , idinga role="tablist", role="tab", role="tabpanel", nezibaluli ezengeziwe aria-ukuze kudluliselwe ukwakheka kwazo, ukusebenza nesimo samanje kubasebenzisi bobuchwepheshe obusizayo (njengabafundi besikrini).

Qaphela ukuthi ukuxhumana kwamathebhu ashukumisayo akufanele kuqukathe amamenyu okwehlayo, njengoba lokhu kubangela kokubili izinkinga zokusebenziseka nokufinyeleleka. Ngokombono wokusebenziseka, iqiniso lokuthi i-elementi ye-trigger yethebhu ebonisiwe okwamanje ayibonakali ngokushesha (njengoba ingaphakathi kwemenyu yokudonsela phansi evaliwe) ingabangela ukudideka. Ngokombono wokufinyeleleka, okwamanje ayikho indlela ephusile yokubeka lolu hlobo lokwakha kuphethini evamile ye-WAI ARIA, okusho ukuthi ngeke yenziwe iqondakale kalula kubasebenzisi bobuchwepheshe obusizayo.

Ukusiza ukulingana nezidingo zakho, lokhu kusebenza <ul>ngomaka -osuselwe, njengoba kuboniswe ngenhla, noma nganoma iyiphi imakhaphu ethi "zigoqe ngokwakho". Qaphela ukuthi uma usebenzisa i- <nav>, akufanele wengeze kuyo role="tablist"ngokuqondile, njengoba lokhu kuzokhipha indima yomdabu ye-elementi njengophawu lwendawo yokuzulazula. Esikhundleni salokho, shintshela kwenye into (esibonelweni esingezansi, elula <div>) bese uyisonga <nav>.

Via JavaScript

Enable tabbable tabs via JavaScript (each tab needs to be activated individually):

$('#myTab a').on('click', function (e) {
  e.preventDefault()
  $(this).tab('show')
})

You can activate individual tabs in several ways:

$('#myTab a[href="#profile"]').tab('show') // Select tab by name
$('#myTab li:first-child a').tab('show') // Select first tab
$('#myTab li:last-child a').tab('show') // Select last tab
$('#myTab li:nth-child(3) a').tab('show') // Select third tab

Fade effect

To make tabs fade in, add .fade to each .tab-pane. The first tab pane must also have .show to make the initial content visible.

<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>

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

$().tab

Activates a tab element and content container. Tab should have either a data-target or an href targeting a container node in the DOM.

<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item">
    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" id="messages-tab" data-toggle="tab" href="#messages" role="tab" aria-controls="messages" aria-selected="false">Messages</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
  </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>
  $(function () {
    $('#myTab li:last-child a').tab('show')
  })
</script>

.tab(‘show’)

Selects the given tab and shows its associated pane. Any other tab that was previously selected becomes unselected and its associated pane is hidden. Returns to the caller before the tab pane has actually been shown (i.e. before the shown.bs.tab event occurs).

$('#someTab').tab('show')

.tab(‘dispose’)

Destroys an element’s tab.

Events

When showing a new tab, the events fire in the following order:

  1. hide.bs.tab (on the current active tab)
  2. show.bs.tab (on the to-be-shown tab)
  3. hidden.bs.tab (on the previous active tab, the same one as for the hide.bs.tab event)
  4. shown.bs.tab (on the newly-active just-shown tab, the same one as for the show.bs.tab event)

If no tab was already active, then the hide.bs.tab and hidden.bs.tab events will not be fired.

Event Type Description
show.bs.tab This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
shown.bs.tab This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
hide.bs.tab This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use event.target and event.relatedTarget to target the current active tab and the new soon-to-be-active tab, respectively.
hidden.bs.tab This event fires after a new tab is shown (and thus the previous active tab is hidden). Use event.target and event.relatedTarget to target the previous active tab and the new active tab, respectively. 
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
  e.target // newly activated tab
  e.relatedTarget // previous active tab
})
