Elýeterlilik

ARIA Awtorlaşdyryş Amallary Gollanmasy tablisalarynda görkezilişi ýaly dinamiki bellikli interfeýsler, gurluşlaryny, işleýşini we häzirki ýagdaýyny kömekçi tehnologiýalary ulanyjylara (ekran okyjylary ýaly) ýetirmek üçin zerur we goşmaça atributlary talap edýär role="tablist". Iň oňat tejribe hökmünde, bellikler üçin elementleri ulanmagy maslahat berýäris , sebäbi bular täze sahypa ýa-da ýerleşişe däl-de, dinamiki üýtgeşmä itergi berýän dolandyryşlardyr.role="tab"role="tabpanel"aria-<button>

ARIA Awtorlaşdyryş amallary nagşyna laýyklykda diňe häzirki işjeň goýma klawiatura fokusyny alýar. JavaScript plugin işe girizilende tabindex="-1", ähli hereketsiz goýma dolandyryşlarynda gurlar. Häzirki işjeň goýmanyň ünsi jemlenenden soň, kursor düwmeleri öňki / indiki goýmany işjeňleşdirýär we plugin şoňa görä herekettabindex edýär . Şeýle-de bolsa, kursoryň esasy özara täsirleri barada aýdylanda, JavaScript plugininiň keseligine we dikligine tablisa sanawlaryny tapawutlandyrmaýandygyny belläň: tab sanawynyň ugruna garamazdan, ýokarky we çep kursor öňki tablisa, aşak we sag kursor gidýär. indiki goýma.

Umuman aýdanyňda, klawiatura nawigasiýasyny aňsatlaşdyrmak üçin, tab paneliniň içindäki manyly mazmuny öz içine alýan birinji element eýýäm ünsi jemlemese, tab panellerini hem ünsi jemlemek maslahat berilýär. JavaScript plugin bu tarapy çözmäge synanyşmaýar - zerur bolan ýagdaýynda, bellikleriňizi goşup, tab panelleriňizi aç-açan etmeli bolarsyňyz tabindex="0".

Salgy JavaScript plugin , açylýan menýulary öz içine alýan goýlan interfeýsleri goldamaýar , sebäbi bu ulanyş we elýeterlilik meselesini döredýär. Ulanyş nukdaýnazaryndan, häzirki görkezilen goýmanyň trigger elementiniň derrew görünmeýänligi (ýapyk açylan menýunyň içinde bolşy ýaly) bulaşyklyga sebäp bolup biler. Elýeterlilik nukdaýnazaryndan häzirki wagtda bu görnüşli gurluşy adaty WAI ARIA nagyşyna kartalaşdyrmagyň manyly usuly ýok, bu kömekçi tehnologiýalary ulanyjylara aňsatlyk bilen düşünip bolmaýar.

Maglumat atributlaryny ulanmak

data-bs-toggle="tab"Diňe bir elementi ýa-da bir elementi görkezip, hiç hili JavaScript ýazmazdan, tab ýa-da tablet nawigasiýasyny işjeňleşdirip bilersiňiz data-bs-toggle="pill". Bu maglumat atributlaryny ulanyň ýa- .nav-tabsda .nav-pills.

<!-- Nav tabs -->

JavaScript arkaly

JavaScript arkaly tablisa tablisalaryny açyň (her tab aýratynlykda işjeňleşdirilmeli):

const triggerTabList = document.querySelectorAll('#myTab button')
triggerTabList.forEach(triggerEl => {
  const tabTrigger = new bootstrap.Tab(triggerEl)

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

Aýry-aýry bellikleri birnäçe usul bilen işjeňleşdirip bilersiňiz:

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

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

Öçürilen effekt

Salgylaryň ýitmegi .fadeüçin hersine goşuň .tab-pane. Ilkinji goýma paneli .showbaşlangyç mazmuny görünmeli.

Usullar

Asynkron usullar we geçişler

APIhli API usullary asynkron bolup, geçişe başlaýar . Geçiş başlan badyna, ýöne gutarmanka jaň edijä gaýdyp gelýärler . Mundan başga-da, geçiş komponentine çagyryş usuly hasaba alynmaz .

Has giňişleýin maglumat üçin JavaScript resminamalarymyza serediň .

Mazmunyňyzy goýma elementi hökmünde işjeňleşdirýär.

Konstruktor bilen bir tab mysal döredip bilersiňiz, mysal üçin:

const bsTab = new bootstrap.Tab('#myTab')

Usul	Düşündiriş
`dispose`	Bir elementiň goýmasyny ýok edýär.
`getInstance`	DOM elementi bilen baglanyşykly tab mysalyny almaga mümkinçilik berýän statiki usul, ony şeýle ulanyp bilersiňiz : `bootstrap.Tab.getInstance(element)`.
`getOrCreateInstance`	DOM elementi bilen baglanyşykly tablisa mysalyny yzyna gaýtaryp berýän ýa-da başlamadyk ýagdaýynda täzesini döredýän statiki usul. Muny şeýle ulanyp bilersiňiz : `bootstrap.Tab.getOrCreateInstance(element)`.
`show`	Berlen goýmany saýlaýar we baglanyşykly paneli görkezýär. Öň saýlanan başga bir tab saýlanmaýar we oňa bagly panel gizlenýär. Salgy paneli hakykatdanam görkezilmänkä (ýagny `shown.bs.tab`waka ýüze çykmazdan ozal) jaň edijä gaýdyp gelýär.

Wakalar

Täze tab görkezilende wakalar aşakdaky tertipde ýanýar:

hide.bs.tab(häzirki işjeň goýmada)
show.bs.tab(görkezilmeli goýmada)
hidden.bs.tabhide.bs.tab(öňki işjeň goýmada, waka bilen birmeňzeş )
shown.bs.tabshow.bs.tab(täze işjeň görkezilen ýaňy görkezilen goýmada, waka bilen birmeňzeş )

Hiç bir goýma eýýäm işjeň bolmadyk bolsa, wakalar hide.bs.tabwe hidden.bs.tabwakalar atylmaz.

Çäräniň görnüşi	Düşündiriş
`hide.bs.tab`	Bu waka täze goýma görkezilmeli bolanda ýanýar (we şeýlelik bilen öňki işjeň goýma gizlenmeli). Häzirki işjeň goýmany we ýakyn wagtda işjeň boljak täze goýmany ulanyň `event.target`we nyşana alyň.`event.relatedTarget`
`hidden.bs.tab`	Bu waka täze goýma görkezilenden soň ýanýar (we şeýlelik bilen öňki işjeň goýma gizlenýär). Öňki işjeň goýmany we täze işjeň goýmany degişlilikde ulanyň `event.target`we nyşana alyň.`event.relatedTarget`
`show.bs.tab`	Bu waka tab goýmasynda ýanýar, ýöne täze goýma görkezilmänkä. Işjeň goýmany we öňki işjeň goýmany degişlilikde ulanyň `event.target`we nyşana alyň.`event.relatedTarget`
`shown.bs.tab`	Bu waka, görkezme görkezilenden soň tab goýmasynda ýanýar. Işjeň goýmany we öňki işjeň goýmany degişlilikde ulanyň `event.target`we nyşana alyň.`event.relatedTarget`

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