I-Navs kunye neethebhu

Amaxwebhu kunye nemizekelo yendlela yokusebenzisa i-Bootstrap equkiweyo yezinto zokukhangela.

Kweli phepha

Isiseko nav

Ukukhangela kuyafumaneka kwiBootstrap yabelana ngokuphawulwa ngokubanzi kunye nezimbo, ukusuka kwisiseko .navseklasi ukuya kumazwe asebenzayo kunye nabakhubazekileyo. Tshintsha iiklasi zesilungisi ukutshintsha phakathi kwesimbo ngasinye.

Icandelo lesiseko .navlakhiwe nge-flexbox kwaye libonelela ngesiseko esomeleleyo sokwakha zonke iintlobo zezixhobo zokuhamba. Ibandakanya isimbo sokubhala ngaphezulu (sokusebenza ngezintlu), ezinye iikhonkco zekhonkco kwiindawo ezinkulu ezibethayo, kunye nesimbo esisisiseko sabakhubazekileyo.

Icandelo lesiseko .navalibandakanyi naliphi na .activeilizwe. Le mizekelo ilandelayo ibandakanya iklasi, ikakhulu ukubonisa ukuba le klasi ayiqalisi nasiphi na isimbo esikhethekileyo.

Ukuhambisa imo esebenzayo kubuchwephesha bokuncedisa, sebenzisa aria-currentuphawu — usebenzisa pageixabiso lephepha langoku, okanye trueinto yangoku kwiseti.

<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" 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>

Iiklasi zisetyenziswa kulo lonke, ngoko uphawu lwakho lunokuba bhetyebhetye kakhulu. Sebenzisa <ul>s like ngasentla, <ol>ukuba ulandelelwano izinto zakho kubalulekile, okanye roll eyakho nge <nav>element. Kuba .navusebenziso display: flex, amakhonkco e-nav aziphatha ngendlela efanayo nav izinto eziya kwenza, kodwa ngaphandle kophawulo olongezelelweyo.

<nav class="nav">
  <a class="nav-link active" aria-current="page" 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>

Izimbo ezikhoyo

Tshintsha isimbo .navs icandelo kunye modifiers kunye eziluncedo. Xuba kwaye utshatise njengoko kufuneka, okanye uzakhele eyakho.

Ulungelelwaniso oluthe tye

Guqula ulungelelwaniso oluthe tye lwe nav yakho ngezixhobo ze flexbox . Ngokungagqibekanga, ii-navs zilungelelaniswe ekhohlo, kodwa unokuzitshintsha ngokulula zibesembindini okanye zilungelelaniswe ekunene.

Isembindini nge .justify-content-center:

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

Ilungelelaniswe ekunene ne .justify-content-end:

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

Ngokuthe nkqo

Gcina ukukhangela kwakho ngokutshintsha isikhokelo sento eguqukayo kunye nezinto .flex-columneziluncedo. Ngaba kufuneka uzibeke kwezinye iindawo zokujonga kodwa hayi kwezinye? Sebenzisa iinguqulelo eziphendulayo (umz., .flex-sm-column).

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

Njengesiqhelo, ukukhangela ngokuthe nkqo kunokwenzeka ngaphandle kwe <ul>-s, kwakhona.

<nav class="nav flex-column">
  <a class="nav-link active" aria-current="page" 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>

Iithebhu

Ithatha i-nav esisiseko ukusuka phezulu kwaye yongeza .nav-tabsiklasi ukwenza ujongano olunethabhu. Zisebenzise ukwenza imimandla enokwenzeka ngethebhu yethu iplagi yeJavaScript .

<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">
    <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>

Iipilisi

Thatha kwaloo HTML inye, kodwa sebenzisa .nav-pillsendaweni yoko:

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

Gcwalisa kwaye ugwebe

Nyanzelisa .navimixholo yakho ukwandisa ububanzi obukhoyo obugcweleyo kwiiklasi ezimbini zesilungisi. Ukugcwalisa ngokulinganayo yonke indawo ekhoyo ngeyakho .nav-item, sebenzisa .nav-fill. Qaphela ukuba yonke indawo ethe tye ihleli, kodwa ayizizo zonke izinto ze-nav ezinobubanzi obufanayo.

<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>
  </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>

Xa usebenzisa <nav>ukukhangela okusekwe, ungashiya ngokukhuselekileyo .nav-itemnjengoko .nav-linkkufuneka kuphela kwizinto zesitayile <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" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Kwizinto ezinobubanzi obulinganayo, sebenzisa .nav-justified. Zonke isithuba esithe tyaba siya kuhlala ngamakhonkco e-nav, kodwa ngokungafaniyo .nav-fillnokungasentla, yonke into ye-nav iya kuba nobubanzi obufanayo.

<ul class="nav nav-pills nav-justified">
  <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>
  </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>

Ngokufana .nav-fillnomzekelo usebenzisa <nav>ukukhangela okusekwe.

<nav class="nav nav-pills nav-justified">
  <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" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Ukusebenza ngezixhobo eziguqukayo

Ukuba ufuna ukusabela okwahluka kwe-nav, cinga ukusebenzisa uluhlu lwezinto eziluncedo ze- flexbox . Ngelixa i-verbose ngakumbi, ezi zixhobo zibonelela ngokwenziwa ngokwezifiso okukhulu kuzo zonke iindawo ezisabelayo. Kulo mzekelo ungezantsi, i-nav yethu iya kupakishwa kweyona ndawo isezantsi yoqhawulo, emva koko ilungelelanise ubeko oluthe tye olugcwalisa ububanzi obukhoyo ukusuka kwindawo encinci yokuphumla.

<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>
  <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>

Ngokumalunga nokufikeleleka

Ukuba usebenzisa i-navs ukubonelela ngebar yokukhangela, qiniseka ukuba wongeza role="navigation"u-a kwesona sikhongozeli sinomzali sisengqiqweni se-, <ul>okanye usonge into ethile kuhambo <nav>lonke. Musa ukongeza indima kuyo <ul>ngokwayo, njengoko oku kuya kuthintela ukuba ibhengezwe njengoluhlu lokwenyani ngobuchule bokuncedisa.

Qaphela ukuba iibar zokukhangela, nokuba zibukeka njenge tabhu kunye .nav-tabsnodidi, akufuneki zinikwe role="tablist", role="tab"okanye role="tabpanel"iimpawu. Ezi zilungele kuphela ujongano oluguquguqukayo lwethebhu, njengoko kuchaziwe kwi- WAI ARIA yeZenzo zokuBhalisa . Jonga ukuziphatha kweJavaScript yojongano oluguquguqukayo lwethebhu kweli candelo lomzekelo. Uphawu aria-currentloyelelwano aluyomfuneko kujongano oluguquguqukayo lwe tab ukususela ekubeni iJavaScript yethu iphethe imeko ekhethiweyo ngokongeza aria-selected="true"kwisithuba esisebenzayo.

Ukusebenzisa iidrophu

Yongeza iimenu ezihlayo nge-HTML encinci eyongezelelweyo kunye neplagi ye- JavaScript eyehlayo .

Iithebhu ezinokwehla

Ukuziphatha kweJavaScript

Sebenzisa i-plugin ye-JavaScript yethebhu-yibandakanye ngabanye okanye bootstrap.jsngefayile edibeneyo-ukwandisa iithebhu zethu zokuhamba kunye neepilisi ukwenza iipaneli ze-tableable zomxholo wendawo.

I-Dynamic tabbed interfaces, njengoko ichazwe kwi- WAI ARIA yeZenzo zokuBhalisa , ifuna role="tablist", role="tab", role="tabpanel", kunye neempawu ezongezelelweyo aria-ukwenzela ukuhambisa isakhiwo sabo, ukusebenza kunye nemeko yangoku kubasebenzisi bobuchwepheshe bokuncedisa (njengabafundi besikrini). Njengomsebenzi ogqwesileyo, sincoma ukusebenzisa <button>izinto zeethebhu, njengoko ezi zizilawuli ezibangela utshintsho oluguquguqukayo, kunezikhonkco eziya kwiphepha elitsha okanye indawo.

Qaphela ukuba ujongano oluguquguqukayo lwe tab akufuneki luqulathe iimenu ezilahlayo, njengoko oku kubangela zombini ukusetyenziswa kunye nemiba yofikelelo. Ukusuka kwimbono yokusebenziseka, into yokuba isiqalo sethebhu ebonisiweyo ngoku ayibonakali ngokukhawuleza (njengoko ingaphakathi kwimenyu eyehlayo evaliweyo) inokubangela ukubhideka. Ukusuka kumbono wofikelelo, okwangoku akukho ndlela isengqiqweni yokwenza imephu yolu hlobo lolwakhiwo kwipatheni eqhelekileyo ye-WAI ARIA, nto leyo ethetha ukuba ayinakwenziwa lula ukuba iqondeke kubasebenzisi bobuchwephesha bokuncedisa.

Lo ngomnye umxholo wesibambi-ndawo ithebhu yaseKhaya umxholo onxulumeneyo. Ukucofa enye isithuba kuya kuguqulela ukubonakala kwalena kwelandelayo. Ithebhu yeJavaScript itshintshanisa iindidi zokulawula ukubonakala komxholo kunye nesimbo. Ungayisebenzisa kunye neethebhu, iipilisi, kunye naluphi na olunye .navukukhangela okunamandla.

Ukusebenzisa iimpawu zedatha

Unokwenza ithebhu okanye ukukhangela iipilisi ngaphandle kokubhala nayiphi na iJavaScript ngokuchaza ngokulula data-bs-toggle="tab"okanye data-bs-toggle="pill"kwinto. Sebenzisa ezi mpawu zedatha kwi .nav-tabsokanye .nav-pills.

NgeJavaScript

Yenza iithebhu ezinokubakho ngeJavaScript (ithebhu nganye kufuneka ivulwe ngokwayo):

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

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

Unokwenza ithebhu nganye isebenze ngeendlela ezininzi:

var triggerEl = document.querySelector('#myTab a[href="#profile"]')
bootstrap.Tab.getInstance(triggerEl).show() // Select tab by name

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

Fade isiphumo

Ukwenza iithebhu ziphelelwe, yongeza .fadekuyo nganye .tab-pane. Ipheyini yethebhu yokuqala kufuneka kwakhona .showyenze umxholo wokuqala ubonakale.

<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>

constructor

Yenza isiqalelo sethebhu kunye nesiqulatho sisebenze. Isithuba kufuneka sibene data-bs-targetokanye, ukuba usebenzisa ikhonkco, uphawu hrefloyelelwano, lujolise kwindawo yesikhongozeli kwiDOM.

<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 a')
  var firstTab = new bootstrap.Tab(firstTabEl)

  firstTab.show()
</script>

bonisa

Ikhetha isithuba esinikiweyo kwaye ibonise isahlulo sayo esinxulumeneyo. Nayiphi enye isithuba ebesikhe yakhethwa ngaphambili ayikhethwanga kwaye isahlulo sayo esinxulumeneyo siyafihlwa. Ibuyisela kumnxebi phambi kokuba ipayini yethebhu iboniswe ngokwenene (okt phambi kokuba shown.bs.tabisiganeko senzeke).

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

  tab.show()

lahla

Uyonakalisa ithebhu yesiqalelo.

getInstance

Indlela engatshintshiyo ekuvumela ukuba ufumane isithuba sesithuba esidityaniswe nesiqalelo seDOM

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

getOrCreateInstance

Indlela engatshintshiyo ekuvumela ukuba ufumane umzekelo wethebhu edityaniswe nento yeDOM, okanye wenze entsha ukuba ayiqalwanga.

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

Iziganeko

Xa ubonisa ithebhu entsha, iziganeko zivutha ngolu hlobo lulandelayo:

hide.bs.tab(kwithebhu esebenzayo yangoku)
show.bs.tab(kwi-eza kuboniswa thebhu)
hidden.bs.tab(kwithebhu esebenzayo yangaphambili, efanayo nale hide.bs.tabyesiganeko)
shown.bs.tab(kwisithuba esandula ukusebenza esivele sibonise ithebhu, efanayo show.bs.tabnesesiganeko)

Ukuba akukho thebhu ibisele iyasebenza, ngoko i hide.bs.tabkunye hidden.bs.tabneziganeko aziyi kugxothwa.

Uhlobo lomsitho	Inkcazo
`show.bs.tab`	Esi siganeko sivutha kumboniso wethebhu, kodwa ngaphambi kokuba ithebhu entsha iboniswe. Sebenzisa `event.target`kunye `event.relatedTarget`nokujolisa isithuba esisebenzayo kunye nesithuba sangaphambili esisebenzayo (ukuba sikhona) ngokulandelelanayo.
`shown.bs.tab`	Esi siganeko sitshisa kwi-tab show emva kokuba ithebhu ibonisiwe. Sebenzisa `event.target`kunye `event.relatedTarget`nokujolisa isithuba esisebenzayo kunye nesithuba sangaphambili esisebenzayo (ukuba sikhona) ngokulandelelanayo.
`hide.bs.tab`	Esi siganeko sitshisa xa isithuba esitsha siza kuboniswa (kwaye ke isithuba sangaphambili esisebenzayo siza kufihlwa). Sebenzisa `event.target`kunye `event.relatedTarget`nokujolisa ithebhu esebenzayo yangoku kunye nethebhu entsha eza kusebenza ngokukhawuleza, ngokulandelelanayo.
`hidden.bs.tab`	Esi siganeko sivutha emva kokuba ithebhu entsha ibonisiwe (kwaye ke isithuba sangaphambili esisebenzayo sifihliwe). Sebenzisa `event.target`kunye `event.relatedTarget`nokujolisa kwithebhu esebenzayo yangaphambili kunye nethebhu entsha esebenzayo, ngokulandelelanayo.

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
})
