Amaqhosha

Sebenzisa izimbo zeqhosha le-Bootstrap ukwenza izinto kwiifom, iingxoxo, kunye nokunye ngenkxaso yeesayizi ezininzi, amazwe, kunye nokunye.

Kweli phepha

Imizekelo

I-Bootstrap ibandakanya izitayile zamaqhosha achazwe kwangaphambili, nganye isebenzela injongo yayo ye-semantic, kunye nokongezwa okumbalwa okuphoswe kulawulo olungaphezulu.

<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>

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-hiddeneklasini.

Khubaza ukusonga umbhalo

Ukuba awufuni ukuba umbhalo weqhosha usongelwe, unokongeza .text-nowrapiklasi kwiqhosha. Kwi-Sass, unokuseta $btn-white-space: nowrapukuvala ukuvalwa kokubhaliweyo kwiqhosha ngalinye.

Iithegi zeqhosha

Iiklasi .btnziyilelwe 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.

Ikhonkco

<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>

Ezinye izimbo zamaqhosha zisebenzisa umbala ongaphambili okhanyayo, kwaye kufuneka usetyenziswe kuphela kwimvelaphi emnyama ukuze kubekho umahluko owaneleyo.

Ubukhulu

Unqwenela amaqhosha amakhulu okanye amancinci? Yongeza .btn-lgokanye .btn-smiisayizi 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 disableduphawu lwe boolean kuyo nayiphi na <button>into. Amaqhosha avaliweyo pointer-events: noneasetyenzisiwe, 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 ayiluxhasi disableduphawu, ngoko ke kufuneka udibanise .disablediklasi ukuyenza ibonakale ingasebenzi.
Ezinye izimbo ezilungele ixesha elizayo zibandakanyiwe ukuvala zonke pointer-eventskumaqhosha eankile.
Amaqhosha angasebenziyo asebenzisayo <a>kufuneka abandakanye aria-disabled="true"uphawu lokubonisa imeko yento kwiitekhnoloji ezincedisayo.
Amaqhosha angasebenziyo asebenzisayo <a> akufuneki aquke hrefuphawu loyelelwano.

Ikhonkco eliphambili Ikhonkco

<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 hrefuphawu kwikhonkco elikhubazekileyo, .disablediklasi isebenzisa pointer-events: noneukuzama 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.

Ikhonkco eliphambili Ikhonkco

<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 mdyoqhawulo, apho .d-md-blockithatha indawo .d-gridyodidi, 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.

Ngokubonakalayo, la maqhosha okuguqula ayafana kwibhokisi yokukhangela amaqhosha okuguqula . Nangona kunjalo, zihanjiswa ngokwahlukileyo ngobuchwepheshe obuncedisayo: iibhokisi zokukhangela ziya kubhengezwa ngabafundi besikrini njenge "tshekiweyo"/"ayikhangelwanga" (ekubeni, ngaphandle kwenkangeleko yazo, iseziibhokisi zokukhangela), ngelixa la maqhosha okuguqula aya kubhengezwa njengawo. “iqhosha”/“iqhosha licinezelwe”. Ukukhetha phakathi kwezi ndlela zimbini kuya kuxhomekeka kuhlobo loguqulo olwenzayo, kwaye nokuba uguqulo luya kwenza ingqiqo kubasebenzisi xa bebhengezwa njengebhokisi yokukhangela okanye njengeqhosha lokwenyani.

Guqula amazwe

Yongeza data-bs-toggle="button"ukuguqula imeko yeqhosha active. Ukuba ucofa ngaphambili iqhosha, kufuneka wongeze .activeiklasi 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>

Guqula ikhonkco Ikhonkco lokuguqula elisebenzayo Ikhonkco lokuguqula livaliwe

<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()
})
