Amafomu
Izibonelo nemihlahlandlela yokusetshenziswa yezitayela zokulawula amafomu, izinketho zesakhiwo, kanye nezingxenye zangokwezifiso zokudala amafomu anhlobonhlobo.
Uhlolojikelele
Izilawuli zefomu le-Bootstrap zinwebeka kuzitayela zethu zefomu Eqaliswe kabusha ngamakilasi. Sebenzisa lawa makilasi ukuze ungene ezibonisini zazo ezenziwe ngokwezifiso ukuze uthole ukunikezwa okungaguquki kuzo zonke iziphequluli namadivayisi.
Qiniseka ukuthi usebenzisa type
isibaluli esifanelekile kukho konke okokufaka (isb., email
ikheli le-imeyili noma number
ulwazi lwezinombolo) ukuze usizakale ngezilawuli zokufakwayo ezintsha njengokuqinisekisa i-imeyili, ukukhetha izinombolo, nokuningi.
Nasi isibonelo esisheshayo sokubonisa izitayela zefomu le-Bootstrap. Qhubeka ufunda ukuze uthole imibhalo ngamakilasi adingekayo, ukwakheka kwefomu, nokunye.
<form>
<div class="mb-3">
<label for="exampleInputEmail1" class="form-label">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp">
<div id="emailHelp" class="form-text">We'll never share your email with anyone else.</div>

Umbhalo wefomu
Umbhalo wezinga lokuvimba noma izinga eliphakathi komugqa ungadalwa kusetshenziswa i- .form-text
.
Ukuhlobanisa umbhalo wefomu nezilawuli zefomu
Umbhalo wefomu kufanele uhlotshaniswe ngokusobala nokulawula kwefomu elihlobene nokusebenzisa aria-describedby
isibaluli. Lokhu kuzoqinisekisa ukuthi ubuchwepheshe obusizayo—njengabafundi besikrini—buzomemezela leli fomu lombhalo lapho umsebenzisi egxile noma engena ekulawuleni.
Umbhalo wefomu ongezansi ungabhalwa ngokuthi .form-text
. Uma kuzosetshenziswa i-elementi yeleveli yebhulokhi, i-margin ephezulu iyengezwa ukuze kube lula ukuhlukanisa okokufaka ngenhla.
<label for="inputPassword5" class="form-label">Password</label>
<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
<div id="passwordHelpBlock" class="form-text">
Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
</div>
Umbhalo osemgqeni ungasebenzisa noma iyiphi into evamile ye-HTML esemgqeni (kungaba i- <span>
, <small>
, noma enye into) ngaphandle kokunye ngaphandle .form-text
kwekilasi.
<div class="row g-3 align-items-center">
<div class="col-auto">
<label for="inputPassword6" class="col-form-label">Password</label>
</div>
<div class="col-auto">
<input type="password" id="inputPassword6" class="form-control" aria-describedby="passwordHelpInline">
</div>
<div class="col-auto">
<span id="passwordHelpInline" class="form-text">
Must be 8-20 characters long.
</span>
</div>

Amafomu akhutshaziwe
Engeza disabled
isibaluli se-boolean kokokufaka ukuze uvimbele ukusebenzisana komsebenzisi futhi ukwenze kubonakale kulula.
<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Engeza disabled
isibaluli kokuthi a <fieldset>
ukuze ukhubaze zonke izilawuli ezingaphakathi. Iziphequluli ziphatha zonke izilawuli zefomu lomdabu ( <input>
, <select>
, <button>
nezici) ngaphakathi <fieldset disabled>
njengezikhutshaziwe, zivimbela kokubili ukusebenzisana kwekhibhodi negundane kuzo.
Kodwa-ke, uma ifomu lakho lihlanganisa nezinto ezifana nenkinobho yangokwezifiso njengokuthi <a class="btn btn-*">...</a>
, lezi zizonikezwa kuphela isitayela se- pointer-events: none
, okusho ukuthi zisagxila futhi zisebenziseka kusetshenziswa ikhibhodi. Kulesi simo, kufanele uguqule lezi zilawuli mathupha ngokungeza tabindex="-1"
ukuze uzivikele ekutholeni ukugxila futhi aria-disabled="disabled"
ubonise isimo sazo kubuchwepheshe obusizayo.

<fieldset disabled>
<legend>Disabled fieldset example</legend>
<div class="mb-3">
<label for="disabledTextInput" class="form-label">Disabled input</label>
<input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">

Ukufinyeleleka
Qinisekisa ukuthi zonke izilawuli zefomu zinegama elifanele elifinyelelekayo ukuze injongo yazo idluliselwe kubasebenzisi bobuchwepheshe obusizayo. Indlela elula yokufeza lokhu ukusebenzisa <label>
isici, noma—uma kuyizinkinobho—ukufaka umbhalo ochazayo ngokwanele njengengxenye <button>...</button>
yokuqukethwe.
Ezimweni lapho kungenzeki khona ukufaka umbhalo obonakalayo <label>
noma ofanelekile, kunezindlela ezihlukile zokuhlinzeka ngegama elifinyelelekayo, njenge:
<label>
izici ezifihliwe kusetshenziswa.visually-hidden
ikilasi- Ikhomba into ekhona engase isebenze njengelebula esetshenziswayo
aria-labelledby
- Ukunikeza
title
isibaluli - Ukusetha ngokusobala igama elifinyeleleka ku-elementi usebenzisa
aria-label
Uma kungekho kulokhu okukhona, ubuchwepheshe obusizayo bungase buphendukele ekusebenziseni placeholder
isibaluli njengembuyiselo yegama elifinyelelekayo elikuwo <input>
nama - <textarea>
elementi. Izibonelo kulesi sigaba zinikeza izindlela ezimbalwa eziphakanyisiwe, eziqondene necala elithile.
Ngenkathi usebenzisa okuqukethwe okufihliwe okubonakalayo ( .visually-hidden
, aria-label
, ngisho placeholder
nokuqukethwe, okunyamalalayo uma inkambu yefomu inokuqukethwe) kuzozuzisa abasebenzisi bobuchwepheshe obusizayo, ukuntuleka kombhalo welebula obonakalayo kungase kube inkinga kubasebenzisi abathile. Olunye uhlobo lwelebula ebonakalayo ngokuvamile luyindlela engcono kakhulu, kokubili yokufinyeleleka nokusebenziseka.
Sass
Amafomu amaningi aguquguqukayo asethwe ezingeni elijwayelekile ukuze aphinde asetshenziswe futhi andwe ngezingxenye zefomu ngazinye. Uzobona lezi kaningi njengama $btn-input-*
- $input-*
variables.
Okuguquguqukayo
$btn-input-*
okuguquguqukayo kwabelwana ngezinto eziguquguqukayo zomhlaba wonke phakathi kwezinkinobho zethu nezingxenye zethu zefomu. Uzothola lezi zivame ukwabiwa kabusha njengamanani kwezinye izinto eziguquguqukayo eziqondene nengxenye.
