Ffoomu eziri mu layini

Kozesa .form-inlineekibiina okulaga omuddirirwa gw’ebiwandiiko, ebifuga ffoomu, ne buttons ku lunyiriri lumu olw’okwebungulula. Ebifuga foomu munda mu foomu eziri mu layini byawukana katono okuva ku mbeera zaabwe ezisookerwako.

  • Ebifuga bye bino display: flex, okumenya ekifo kyonna ekyeru ekya HTML era ne kikusobozesa okuwa okufuga okulaganya n’ebikozesebwa mu bbanga n’ebikozesebwa mu flexbox .
  • Ebifuga n'ebibinja by'okuyingiza bifuna width: autookusazaamu Bootstrap default width: 100%.
  • Ebifuga birabika mu layini byokka mu bifo eby’okulaba ebirina obugazi waakiri 576px okusobola okubala ebifo ebifunda eby’okulaba ku byuma ebikozesebwa ku ssimu.

Oyinza okwetaaga okukola mu ngalo ku bugazi n’okulaganya kw’ebifuga bya ffoomu ssekinnoomu n’ebikozesebwa eby’okuteeka ebanga (nga bwe kiragibwa wansi). Ekisembayo, kakasa nti bulijjo ossaamu a <label>ne buli ffoomu control, ne bw’oba ​​weetaaga okugikweka abagenyi abatali screenreader ne .sr-only.

Ebikozesebwa ebirala okusinga ebiwandiiko ebikwekebwa

Tekinologiya ayamba nga screen readers ajja kuba n’obuzibu ne forms zo singa tossaamu label ku buli input. Ku foomu zino eziri mu layini, osobola okukweka ebiwandiiko ng’okozesa .sr-onlyekibiina. Waliwo enkola endala ez’okuwa akabonero ku tekinologiya ayamba, gamba nga aria-label, aria-labelledbyoba titleekintu. Singa tewali n’emu ku zino ebaawo, tekinologiya ayamba ayinza okuddukira mu kukozesa placeholderekintu ekyo, bwe kiba nga kiriwo, naye weetegereze nti okukozesa placeholderng’ekifo ky’enkola endala ez’okuwandiika obubonero tekiba kirungi.

Ekiwandiiko ekiyamba

Ebiwandiiko by’obuyambi eby’omutendera gwa bbulooka mu foomu bisobola okutondebwa nga tukozesa .form-text(eyali emanyiddwa nga .help-blockmu v3). Ebiwandiiko by'obuyambi ebiri mu layini bisobola okuteekebwa mu nkola mu ngeri ekyukakyuka nga tukozesa ekintu kyonna ekya HTML ekiri mu layini ne kiraasi z'omugaso nga .text-muted.

Okukwataganya ekiwandiiko ky'obuyambi n'ebifuga foomu

Ekiwandiiko ky’obuyambi kirina okukwatagana mu bulambulukufu n’okufuga foomu kye kikwatagana n’okukozesa aria-describedbyekintu. Kino kijja kukakasa nti tekinologiya ayamba —nga ebisoma ku ssirini —ajja kulangirira ekiwandiiko kino eky’obuyambi ng’omukozesa assa essira oba ng’ayingira mu kifuga.

Ebiwandiiko by'obuyambi wansi w'ebiyingizibwa bisobola okukolebwako sitayiro ne .form-text. Kiraasi eno erimu display: blockera n’eyongerako margin ezimu ez’okungulu okusobola okwanguyiza ebanga okuva ku biyingizibwa waggulu.

Ekigambo kyo eky’okuyingira kirina okuba nga kirimu ennukuta 8-20, nga kirimu ennukuta ne nnamba, era tekirina kubaamu bifo, ennukuta ez’enjawulo, oba emoji. 
<label for="inputPassword5">Password</label>
<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
<small id="passwordHelpBlock" class="form-text text-muted">
  Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
</small>

Ebiwandiiko ebiri mu layini bisobola okukozesa ekintu kyonna ekya bulijjo ekya HTML ekiri mu layini (kabeere <small>, <span>, oba ekintu ekirala) nga tekirina kirala okuggyako kiraasi y’omugaso.

Alina okuba n’obuwanvu bw’ennukuta 8-20. 
<form class="form-inline">

Ffoomu z’abalema

Okwongerako ekintu kya disabledboolean ku kiyingizibwa okuziyiza enkolagana z'abakozesa n'okukifuula okulabika ng'ekitangaala.

<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Okwongerako disabledekintu ku a <fieldset>okulemesa ebifuga byonna ebiri munda.

Ekyokulabirako ky'ensengeka y'ennimiro eremeddwa 
<form>
  <fieldset disabled>
    <legend>Disabled fieldset example</legend>
    <div class="form-group">
      <label for="disabledTextInput">Disabled input</label>
      <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
    </div>
    <div class="form-group">
      <label for="disabledSelect">Disabled select menu</label>
      <select id="disabledSelect" class="form-control">
        <option>Disabled select</option>
      </select>
    </div>
    <div class="form-group">
      <div class="form-check">
        <input class="form-check-input" type="checkbox" id="disabledFieldsetCheck" disabled>
        <label class="form-check-label" for="disabledFieldsetCheck">
          Can't check this
        </label>
      </div>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </fieldset>
</form>
Okulabula nga olina ennanga

Browsers zitwala byonna ebifuga ffoomu enzaaliranwa ( <input>, <select>, ne <button>elements) munda mu a <fieldset disabled>nga ebiremeseddwa, okulemesa byombi keyboard ne mouse enkolagana ku byo.

Naye, singa foomu yo era erimu ebintu ebiringa bbaatuuni eya bulijjo nga <a ... class="btn btn-*">, bino bijja kuweebwa sitayiro ya pointer-events: none. Nga bwe kyayogerwa mu kitundu ekikwata ku mbeera elemeseddwa ku buttons (n’okusingira ddala mu kitundu ekitono eky’ebintu ebinyweza), ekintu kino ekya CSS tekinnaba ku mutindo era tekinnawagirwa mu bujjuvu mu Internet Explorer 10. Ebifuga ebyesigamiziddwa ku nnanga nabyo bijja kuba bikyali bwe bityo focusable era nga ekola nga okozesa keyboard. Olina okukyusa mu ngalo ebifuga bino ng’ogattako tabindex="-1"okubiziyiza okufuna essira n’okulaga aria-disabled="disabled"embeera yabyo eri tekinologiya ayamba.

Okukwatagana kwa cross-browser

Wadde nga Bootstrap ejja kukozesa emisono gino mu browser zonna, Internet Explorer 11 ne wansi tewagira mu bujjuvu disabledattribute ku a <fieldset>. Kozesa JavaScript eya bulijjo okulemesa fieldset mu browser zino.

Okukakasa

Okuwa endowooza ez’omuwendo, ezisobola okukolebwa eri abakozesa bo n’okukakasa foomu ya HTML5– esangibwa mu bulawuzi zaffe zonna eziwagirwa . Londa okuva mu browser default validation feedback, oba teeka mu nkola obubaka obw'ennono ne classes zaffe ezimbiddwamu ne JavaScript etandika.

Tukimanyi nti mu kiseera kino emisono gy’okukakasa egy’ennono egy’oludda lwa kasitoma n’obukodyo bw’ebikozesebwa tebituukirirwa, okuva bwe kiri nti tebikwatibwa tekinologiya ayamba. Nga tukola ku solution, twandikuwadde amagezi okukozesa enkola ya server-side oba enkola ya default browser validation.

Engeri gye kikola

Laba engeri okukakasa foomu gye kukola ne Bootstrap:

  • Okukakasa foomu ya HTML kukozesebwa okuyita mu CSS's two pseudo-classes, :invalidne :valid. Kikwata ku <input>, <select>, ne <textarea>elementi.
  • Bootstrap scopes the :invalidne :validstyles ku kiraasi y'omuzadde .was-validated, ebiseera ebisinga ekozesebwa ku <form>. Bwe kitaba ekyo, ennimiro yonna eyeetaagisa nga tewali muwendo eraga nga si ntuufu ku kutikka omuko. Mu ngeri eno, oyinza okusalawo ddi lw’ogenda okuzikola (ebiseera ebisinga oluvannyuma lw’okugezaako okuleeta foomu).
  • Okuddamu okuteekawo endabika ya foomu (okugeza, mu mbeera y’okuweereza foomu okukyukakyuka nga okozesa AJAX), ggyawo .was-validatedekibiina okuva mu <form>nate oluvannyuma lw’okuweereza.
  • Nga fallback, .is-invalidera .is-validclasses ziyinza okukozesebwa mu kifo kya pseudo-classes for server side validation . Tezeetaaga .was-validatedkibiina kya bazadde.
  • Olw'ebizibu mu ngeri CSS gy'ekola, tetusobola (mu kiseera kino) kukozesa sitayiro ku a <label>ejja nga tennabaawo kufuga ffoomu mu DOM awatali buyambi bwa JavaScript eya bulijjo.
  • Browser zonna ez’omulembe ziwagira constraint validation API , omuddirirwa gw’enkola za JavaScript ez’okukakasa ebifuga foomu.
  • Obubaka bw’okuddamu buyinza okukozesa ebisookerwako bya bbulawuzi (eby’enjawulo ku buli bbulawuzi, era nga tebiyinza kukolebwa nga biyita mu CSS) oba emisono gyaffe egy’okuddamu egy’ennono nga giriko HTML ne CSS ez’enjawulo.
  • Oyinza okuwa obubaka obw'obutuufu obw'ennono ne setCustomValiditymu JavaScript.

Nga olina ekyo mu birowoozo, lowooza ku demos zino wammanga ez’emisono gyaffe egy’okukakasa foomu egy’ennono, kiraasi z’oludda lwa seva ez’okwesalirawo, n’ebisookerwako bya bbulawuzi.

Emisono egy’enjawulo

Ku bubaka obw'okukakasa foomu ya Bootstrap eya bulijjo, ojja kwetaaga okwongerako ekintu kya novalidateboolean ku <form>. Kino kiremesa ebikozesebwa eby'okuddamu ebisookerwako ebya bbulawuzi, naye nga kikyawa olukusa ku API z'okukakasa foomu mu JavaScript. Gezaako okuleeta foomu eno wammanga; JavaScript yaffe ejja kukwata button y'okuweereza n'okukuweereza endowooza yo. Bw’oba ​​ogezaako okuleeta, ojja kulaba :invalidne :validsitayiro nga zikozesebwa ku bifuga foomu yo.

Emisono gy’okuddamu egy’enjawulo gikozesa langi ez’enjawulo, ensalosalo, emisono gy’okussa essira, n’ebifaananyi eby’emabega okusobola okuwuliziganya obulungi ebiteeso. Ebifaananyi eby'emabega ebya <select>s bifunibwa ne .custom-select, so si .form-control.

Mulimu maapu eteekeddwa mu kisenge okulongoosa langi n’akabonero ka buli ssaza. Wadde nga tewali masaza malala gawagirwa bbulawuzi, abo abakozesa emisono egy’enjawulo basobola bulungi okwongerako ebiteeso bya ffoomu ebizibu ennyo.

Ffoomu ez’ennono

Okusobola n’okusingawo okulongoosa n’okukwatagana kwa bbulawuzi okusalako, kozesa ebintu byaffe ebya ffoomu eby’enjawulo ddala okudda mu kifo ky’ebisookerwako ebya bbulawuzi. Zizimbibwa waggulu ku semantic ne accessible markup, kale zibeera solid replacements for any default form control.

Ebibokisi ebikebera ne leediyo

Buli checkbox ne radio <input>ne <label>pairing bizingibwa mu a <div>okukola custom control yaffe. Mu nsengeka, eno y’enkola y’emu n’enkola yaffe eya bulijjo .form-check.

Tukozesa ekisunsula baganda ( ~) ku masaza gaffe <input>gonna —nga :checked—okukola obulungi sitayiro y’ekiraga foomu yaffe ey’ennono. Bwe tugattibwa ne .custom-control-labelkiraasi, tusobola n’okukola sitayiro y’ekiwandiiko kya buli kintu okusinziira ku mbeera ya <input>'s.

Tukweka ekisookerwako <input>ne opacityera tukozesa .custom-control-labelokuzimba ekiraga foomu empya ey'ennono mu kifo kyakyo ne ::beforene ::after. Ebyembi tetusobola kuzimba custom one okuva just the <input>kubanga CSS's contenttekola ku element eyo.

Mu mbeera ezikebereddwa, tukozesa ebifaananyi bya SVG ebiteekeddwamu base64 okuva mu Open Iconic . Kino kituwa okufuga okusinga obulungi ku sitayiro n’okuteeka mu kifo mu bulawuzi n’ebyuma byonna.

Ebibokisi ebikebera

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheck1">
  <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
</div>

Ebibokisi ebikebera eby’enjawulo nabyo bisobola okukozesa :indeterminateekibiina eky’obulimba nga biteekeddwa mu ngalo nga biyita mu JavaScript (tewali kintu kya HTML ekiriwo eky’okukirambika).

Bw’oba ​​okozesa jQuery, ekintu nga kino kisaana okumala:

$('.your-checkbox').prop('indeterminate', true)

Leediyo

<div class="custom-control custom-radio">
  <input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio1">Toggle this custom radio</label>
</div>
<div class="custom-control custom-radio">
  <input type="radio" id="customRadio2" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio2">Or toggle this other custom radio</label>
</div>

Mu layini

<div class="custom-control custom-radio custom-control-inline">

</div>

Obutesobola

Ebibokisi ebikebera eby’enjawulo ne leediyo nabyo bisobola okulemesa. Okwongerako ekintu kya disabledboolean ku <input>era ekiraga eky'ennono n'ennyonnyola y'akabonero bijja kukolebwa mu sitayiro mu ngeri ey'otoma.

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheckDisabled1" disabled>
  <label class="custom-control-label" for="customCheckDisabled1">Check this custom checkbox</label>

  <label class="custom-control-label" for="customRadioDisabled2">Toggle this custom radio</label>
</div>

Ebikyusakyusa

Sswiiki erina markup ya custom checkbox naye ekozesa .custom-switchclass okulaga toggle switch. Switches nazo ziwagira disabledattribute.

<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" id="customSwitch1">
  <label class="custom-control-label" for="customSwitch1">Toggle this switch element</label>
</div>
<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
  <label class="custom-control-label" for="customSwitch2">Disabled switch element</label>
</div>

Londa menu

Menyu <select>eza custom zeetaaga kiraasi ya custom yokka, .custom-selectokutandika emisono egy'ennono. Emisono egy'enjawulo gikoma ku <select>ndabika ya 's esooka era tesobola kukyusa <option>s olw'obuzibu bwa bbulawuzi.

<select class="custom-select">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Oyinza n'okulonda okuva mu kulonda okutono n'okunene okw'ennono okukwatagana n'ebiwandiiko byaffe ebiyingizibwa mu sayizi y'emu.

<select class="custom-select custom-select-lg mb-3">

Ebanga

Tonda <input type="range">ebifuga eby'ennono ne .custom-range. Oluyimba (emabega) n’engalo ensajja (omuwendo) byombi bikoleddwa mu sitayiro okulabika kye kimu mu bulawuzi zonna. Nga IE ne Firefox zokka bwe ziwagira “okujjuza” oluyimba lwabwe okuva ku kkono oba ku ddyo w’engalo ensajja ng’engeri y’okulaga mu maaso enkulaakulana, mu kiseera kino tetugiwagira.

<label for="customRange1">Example range</label>
<input type="range" class="custom-range" id="customRange1">

Ebiyingizibwa mu bbanga birina emiwendo egy’enjawulo egya minne max— 0ne 100, mu kulondako. Oyinza okulaga emiwendo emipya eri abo abakozesa ebifaananyi minne max.

<label for="customRange2">Example range</label>
<input type="range" class="custom-range" min="0" max="5" id="customRange2">

Nga bwekiba, ebiyingizibwa mu bbanga “snap” ku miwendo gya namba enzijuvu. Okukyusa kino, osobola okulaga stepomuwendo. Mu kyokulabirako wansi, tukubisaamu emirundi ebiri omuwendo gw’emitendera nga tukozesa step="0.5".

<label for="customRange3">Example range</label>
<input type="range" class="custom-range" min="0" max="5" step="0.5" id="customRange3">

Okukebera fayiro

Plugin esengekeddwa okukola obulamu okuyingiza fayiro eya bulijjo: bs-custom-file-input , ekyo kye tukozesa mu kiseera kino wano mu docs zaffe.

Okuyingiza fayiro kwe kusinga gnarly mu kibinja era kyetaagisa JavaScript ey'okugattako bw'oba oyagala okuziyunga n'enkola Londa fayiro... n'ekiwandiiko ky'erinnya lya fayiro ekirondeddwa.

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFile">
  <label class="custom-file-label" for="customFile">Choose file</label>
</div>

Tukweka fayiro eya bulijjo <input>nga tuyita mu opacityera mu kifo ky'ekyo tukola sitayiro ya <label>. Button ekolebwa era n'eteekebwa ne ::after. Ekisembayo, tulangirira a widthne heightku the <input>for proper spacing for surrounding content.

Okuvvuunula oba okulongoosa ennyiriri ne SCSS

Ekika :lang()ky’obulimba kikozesebwa okusobozesa okuvvuunula ekiwandiiko “Browse” mu nnimi endala. Ssa oba yongera ku biyingiziddwa ku $custom-file-textnkyukakyuka ya Sass n'akabonero k'olulimi akakwatagana n'ennyiriri eziteekeddwa mu kitundu . Ennyiriri z’Olungereza zisobola okulongoosebwa mu ngeri y’emu. Okugeza, wuuno engeri omuntu gy'ayinza okwongerako enzivuunula y'Olusipeyini (enkodi y'olulimi Olusipeyini eri es):

$custom-file-text: (
  en: "Browse",
  es: "Elegir"
);

Wano lang(es)mu bikolwa ku kuyingiza fayiro eya bulijjo ey'okuvvuunula mu Lusipeyini:

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFileLang" lang="es">
  <label class="custom-file-label" for="customFileLang">Seleccionar Archivo</label>
</div>

Ojja kwetaaga okuteekawo olulimi lw'ekiwandiiko kyo (oba omuti omutono ogwakyo) mu butuufu okusobola ekiwandiiko ekituufu okulagibwa. Kino kiyinza okukolebwa nga okozesa ekintulang ekiri ku elementi<html> oba Content-Languageomutwe gwa HTTP , mu nkola endala.

Okuvvuunula oba okulongoosa ennyiriri ne HTML

Bootstrap era egaba engeri y’okuvvuunula ekiwandiiko “Browse” mu HTML n’ekintu data-browseekiyinza okugattibwa ku kiwandiiko ky’okuyingiza eky’ennono (okugeza mu Ludaaki):

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFileLangHTML">
  <label class="custom-file-label" for="customFileLangHTML" data-browse="Bestand kiezen">Voeg je document toe</label>
</div>
