Amaqhosha
Sebenzisa izimbo zeqhosha le-Bootstrap ukwenza izinto kwiifom, iingxoxo, kunye nokunye ngenkxaso yeesayizi ezininzi, amazwe, kunye nokunye.
Imizekelo
I-Bootstrap ibandakanya izitayile zamaqhosha achazwe kwangaphambili, nganye isebenzela injongo yayo ye-semantic, kunye nokongezwa okumbalwa okuphoswe kulawulo olungaphezulu.

Ukuhambisa intsingiselo kwiiteknoloji ezincedisayo
Ukusebenzisa umbala ukongeza intsingiselo kubonelela kuphela ngesalathiso esibonakalayo, esingayi kuthunyelwa kubasebenzisi betekhnoloji encedisayo - njengezifundi zesikrini. Qinisekisa ukuba ulwazi olubonakaliswe ngumbala lucacile kumxholo ngokwawo (umzekelo, umbhalo obonakalayo), okanye luqukwe ngezinye iindlela, ezifana nesicatshulwa esongezelelweyo esifihlwe .visually-hidden
eklasini.
Khubaza ukusonga umbhalo
Ukuba awufuni ukuba umbhalo weqhosha usongelwe, unokongeza .text-nowrap
iklasi kwiqhosha. Kwi-Sass, unokuseta $btn-white-space: nowrap
ukuvala ukuvalwa kokubhaliweyo kwiqhosha ngalinye.
Iithegi zeqhosha
Iiklasi .btn
ziyilelwe ukuba zisetyenziswe kunye <button>
nesiqalelo. Nangona kunjalo, ungasebenzisa ezi klasi kwi <a>
okanye <input>
izinto (nangona ezinye iibhrawuza zinokusebenzisa unikezelo olwahluke kancinane).
Xa usebenzisa iiklasi zamaqhosha <a>
kwizinto ezisetyenziselwa ukuqalisa ukusebenza kwekhasi (njengomxholo odilikayo), endaweni yokudibanisa amaphepha amatsha okanye amacandelo angaphakathi kwephepha langoku, la makhonkco kufuneka anikwe role="button"
ukuhambisa ngokufanelekileyo injongo yawo kubuchwephesha obuncedisayo njenge abafundi besikrini.
<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">
Amaqhosha enkcazo
Ngaba ufuna iqhosha, kodwa hayi imibala engasemva enzima abayizisayo? Buyisela iiklasi zesilungisi esingagqibekanga ngezo .btn-outline-*
zokususa yonke imifanekiso yangasemva kunye nemibala kulo naliphi na iqhosha.
<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>
Ubukhulu
Unqwenela amaqhosha amakhulu okanye amancinci? Yongeza .btn-lg
okanye .btn-sm
iisayizi ezongezelelweyo.
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>
Ilizwe labakhubazekileyo
Yenza amaqhosha abonakale engasebenzi ngokongeza disabled
uphawu lwe boolean kuyo nayiphi na <button>
into. Amaqhosha avaliweyo pointer-events: none
asetyenzisiwe, ukunqanda i-hover kunye neemeko ezisebenzayo ekuqaliseni.
<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>
Amaqhosha angasebenziyo asebenzisa <a>
isiqalelo aziphathe ngokwahlukileyo:
<a>
s ayiluxhasidisabled
uphawu, ngoko ke kufuneka udibanise.disabled
iklasi ukuyenza ibonakale ingasebenzi.- Ezinye izimbo ezilungele ixesha elizayo zibandakanyiwe ukuvala zonke
pointer-events
kumaqhosha eankile. - Amaqhosha angasebenziyo asebenzisayo
<a>
kufuneka abandakanyearia-disabled="true"
uphawu lokubonisa imeko yento kwiitekhnoloji ezincedisayo. - Amaqhosha angasebenziyo asebenzisayo
<a>
akufuneki aqukehref
uphawu loyelelwano.
<a class="btn btn-primary btn-lg disabled" role="button" aria-disabled="true">Primary link</a>
<a class="btn btn-secondary btn-lg disabled" role="button" aria-disabled="true">Link</a>
Icaveat yokusebenza kwekhonkco
Ukugubungela iimeko apho kufuneka ugcine href
uphawu kwikhonkco elikhubazekileyo, .disabled
iklasi isebenzisa pointer-events: none
ukuzama ukukhubaza ukusebenza kwekhonkco <a>
s. Qaphela ukuba le propati ye-CSS ayikabikho emgangathweni we-HTML, kodwa zonke iibhrawuza zangoku ziyayixhasa. Ukongeza, nakwiziphequluli ezixhasayo pointer-events: none
, ukukhangela kwekhibhodi kuhlala kungachaphazeleki, okuthetha ukuba abasebenzisi bekhibhodi ababoniweyo kunye nabasebenzisi bobuchwephesha bokuncedisa baya kuba nakho ukwenza la makhonkco asebenze. Ke ukukhuseleka, ukongeza aria-disabled="true"
, kukwabandakanya tabindex="-1"
uphawu kula makhonkco ukuwathintela ekufumaneni ujoliso lwebhodi yezitshixo, kwaye usebenzise iJavaScript yesiko ukukhubaza ukusebenza kwazo ngokupheleleyo.
<a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>
Amaqhosha ebhlokhi
Yenza imfumba ephendulayo yobubanzi obugcweleyo, "amaqhosha ebhloko" njengalawo aseBootstrap 4 ngomxube wokubonisa kwethu kunye nezixhobo ze-gap. Ngokusebenzisa izinto eziluncedo endaweni yeeklasi ezithile zamaqhosha, sinolawulo olukhulu ngakumbi kwisithuba, ulungelelwaniso, kunye nokuziphatha okuphendulayo.
<div class="d-grid gap-2">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Apha senza utshintsho oluphendulayo, siqala ngamaqhosha apakishwe ngokuthe nkqo kude kube kwindawo md
yoqhawulo, apho .d-md-block
ithatha indawo .d-grid
yodidi, ngokwenza njalo ungasebenzi gap-2
. Phinda umlinganiselo wesikhangeli sakho ukuze uzibone zitshintsha.
<div class="d-grid gap-2 d-md-block">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Ungahlengahlengisa ububanzi bamaqhosha akho ebhloko ngeeklasi zobubanzi bekholamu yegridi. Ngokomzekelo, kwi-half-width "iqhosha lebhloko", sebenzisa .col-6
. Yibeke kwindawo ethe tye nge .mx-auto
, nayo.
<div class="d-grid gap-2 col-6 mx-auto">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Izixhobo ezongezelelweyo zingasetyenziselwa ukulungelelanisa ukulungelelaniswa kwamaqhosha xa tye. Apha sithathe umzekelo wethu wangaphambili ophendulayo kwaye songeza izinto eziguqukayo kunye nesixhobo somda kwiqhosha ukulungelelanisa amaqhosha ekunene xa engasapakishwanga.
<div class="d-grid gap-2 d-md-flex justify-content-md-end">
<button class="btn btn-primary me-md-2" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Iqhosha leplagi
I-plugin yeqhosha ikuvumela ukuba wenze lula ukuvula/ukuvala amaqhosha okuguqula.
Guqula amazwe
Yongeza data-bs-toggle="button"
ukuguqula imeko yeqhosha active
. Ukuba ucofa ngaphambili iqhosha, kufuneka wongeze .active
iklasi ngesandla kwaye aria-pressed="true"
uqinisekise ukuba ihanjiswa ngokufanelekileyo kwiiteknoloji ezincedisayo.
<button type="button" class="btn btn-primary" data-bs-toggle="button" autocomplete="off">Toggle button</button>
<button type="button" class="btn btn-primary active" data-bs-toggle="button" autocomplete="off" aria-pressed="true">Active toggle button</button>
<button type="button" class="btn btn-primary" disabled data-bs-toggle="button" autocomplete="off">Disabled toggle button</button>
<a href="#" class="btn btn-primary" role="button" data-bs-toggle="button">Toggle link</a>
<a href="#" class="btn btn-primary active" role="button" data-bs-toggle="button" aria-pressed="true">Active toggle link</a>
<a class="btn btn-primary disabled" aria-disabled="true" role="button" data-bs-toggle="button">Disabled toggle link</a>
Iindlela
Unokwenza umzekelo weqhosha kunye nomakhi weqhosha, umzekelo:
var button = document.getElementById('myButton')
var bsButton = new bootstrap.Button(button)
Indlela | Inkcazo |
---|---|
toggle |
Itshintsha imeko yokutyhala. Inika iqhosha inkangeleko yokuba livuliwe. |
dispose |
Itshabalalisa iqhosha lesiqalelo. (Isusa idatha egciniweyo kwisiqalelo seDOM) |
getInstance |
Indlela engatshintshiyo ekuvumela ukuba ufumane umzekelo weqhosha elihambelana nento yeDOM, ungayisebenzisa ngolu hlobo:bootstrap.Button.getInstance(element) |
getOrCreateInstance |
Indlela engatshintshiyo ebuyisela umzekelo weqhosha eliyanyaniswa nento yeDOM okanye wenze entsha ukuba ayiqalwanga. Ungayisebenzisa ngolu hlobo:bootstrap.Button.getOrCreateInstance(element) |
Umzekelo, ukuguqula onke amaqhosha
var buttons = document.querySelectorAll('.btn')
buttons.forEach(function (button) {
var button = new bootstrap.Button(button)
button.toggle()
})
