Ffoomu

Eby’okulabirako n’ebiragiro by’enkozesa y’emisono gy’okufuga foomu, ensengeka z’okulonda, n’ebitundu eby’enjawulo eby’okukola foomu ez’enjawulo.

Okulaba okutwalira awamu

Ebifuga foomu bya Bootstrap bigaziya ku sitayiro zaffe eza foomu eya Rebooted ne kiraasi. Kozesa kiraasi zino okulonda mu kwolesebwa kwazo okulongooseddwa okusobola okulaga okukwatagana obulungi mu bulawuzi n’ebyuma.

Kakasa nti okozesa ekintu ekituufu typeku biyingizibwa byonna (okugeza, emailku ndagiriro ya email oba numberku mawulire ag’omuwendo) okweyambisa ebifuga ebipya ebiyingizibwa nga okukakasa email, okulonda ennamba, n’ebirala.

Wano waliwo ekyokulabirako eky'amangu okulaga emisono gya Bootstrap egya ffoomu. Sigala ng’osoma okufuna ebiwandiiko ku bibiina ebyetaagisa, ensengeka ya foomu, n’ebirala.

Tetujja kugabana email yo na muntu mulala yenna. 
<form>

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.

Ateekwa okuba ng’obuwanvu bw’ennukuta 8-20.

Ffoomu z’abalema

Okwongerako ekintu kya disabledboolean ku kiyingizibwa okuziyiza enkolagana y'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.

<form>
  <fieldset disabled>
    <div class="form-group">

Okulabula nga olina ennanga

Nga bwekiba, browsers zijja kutwala 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 ffoomu yo nayo erimu <a ... class="btn btn-*">ebintu, bino bijja kuweebwa sitayiro ya pointer-events: none. Nga bwe kyayogerwa mu kitundu ekikwata ku mbeera elemeddwa ku buttons (n’okusingira ddala mu kitundu ekitono eky’ebintu ebinanga), ekintu kino ekya CSS tekinnaba ku mutindo era tekinnawagirwa mu bujjuvu mu Opera 18 ne wansi, oba mu Internet Explorer 10, era kyawangulwa 't okulemesa abakozesa keyboard okusobola okussa essira oba okukola links zino. Kale okusobola okuba n’obukuumi, kozesa JavaScript eya bulijjo okulemesa enkolagana ng’ezo.

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.

Tukuwa amagezi nnyo emisono gy’okukakasa egy’ennono nga ebisookerwako bya bbulawuzi enzaaliranwa tebilangirirwa ku basomi ba screen.

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).
  • 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.

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 bizingibwa mu a <div>ne muganda <span>waffe okukola custom control yaffe ne a <label>ku kiwandiiko ekiwerekerako. Mu nsengeka, eno y’enkola y’emu n’enkola yaffe eya bulijjo .form-check.

Okukebera fayiro

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>

We hide the default file <input> via opacity and instead style the <label>. The button is generated and positioned with ::after. Lastly, we declare a width and height on the <input> for proper spacing for surrounding content.

Translating or customizing the strings

The :lang() pseudo-class is used to allow for translation of the “Browse” text into other languages. Override or add entries to the $custom-file-text Sass variable with the relevant language tag and localized strings. The English strings can be customized the same way. For example, here’s how one might add a Spanish translation (Spanish’s language code is es):

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

Here’s lang(es) in action on the custom file input for a Spanish translation:

<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>
