Baformilɛrɛ oyo ezali na kati ya molɔngɔ

Salelá .form-inlinekelasi mpo na kolakisa molɔngɔ́ ya bilembo, ba contrôles ya formulaire, mpe ba boutons na molongo moko ya horizontal. Ba contrôles ya formulaire na kati ya ba formulaires inline ekeseni mwa moke na ba états na yango ya défaut.

  • Ba contrôles ezali display: flex, ko collapser espace blanc HTML nionso mpe ko permettre yo opesa contrôle ya alignment na ba utilitaires ya espacement na flexbox .
  • Ba contrôles na ba groupes ya entrée bazuaka width: autopona ko superposer défaut ya Bootstrap width: 100%.
  • Ba contrôles emonanaka kaka na kati ya ligne na ba portes de vue oyo ezali au moins 576px ya largeur pona ko comptabiliser ba portes de vue ya mike na ba appareils mobiles.

Ekoki kozala ete osengeli kotalela na mabɔkɔ bonene mpe boyokani ya ba contrôles ya formulaire mokomoko na ba utilitaires ya espacement (ndenge emonisami awa na nse). Na nsuka, kobosana te kotya ntango nyonso a <label>na contrôle ya formulaire moko na moko, ata soki osengeli kobomba yango mpo na bapaya oyo bazali batangi ya écran te na .sr-only.

Ba alternatives na ba étiquettes oyo ebombami

Ba technologies ya kosunga lokola ba lecteurs ya écran ekozala na problème na ba formulaire na yo soki otie étiquette te pona entrée nionso. Mpo na ba formulaire oyo ya inline, okoki kobomba ba étiquettes na kosalelaka .sr-onlyclasse. Ezali na mayele mosusu ya kopesa elembo mpo na mayele ya kosalisa, na ndakisa aria-label, aria-labelledbyto titleattribut. Soki moko te kati na yango ezali, mayele ya kosunga ekoki kosalela placeholderezaleli yango, soki ezali, kasi yebá ete kosalela yango placeholderlokola esika ya mayele mosusu ya kotya bilembo ezali malamu te.

Mokanda ya lisalisi

Mokanda ya lisalisi ya nivo ya bloc na ba formulaire ekoki kosalama na kosalelaka .form-text(eyebanaki liboso lokola .help-blockna v3). Mokanda ya lisalisi ya kati ya molongo ekoki kosalelama na lolenge ya kobongola na kosalelaka eleman HTML nyonso ya kati ya molongo mpe bakelasi ya utilitaire lokola .text-muted.

Kosangisa makomi ya lisalisi na ba contrôles ya formulaire

Mokanda ya lisalisi esengeli kozala na boyokani ya polele na bokonzi ya formulaire oyo ezali na boyokani na kosalela aria-describedbyattribut. Yango ekosala ete mayele ya kosalisa —na ndakisa batángi ya écran —ekosakola makomi oyo ya lisalisi ntango mosaleli azali kotya likebi to akokɔta na esika oyo batambwisaka yango.

Mokanda ya lisalisi na nse ya bokɔti ekoki kozala na lolenge na .form-text. Kelasi oyo ezali display: blockna mpe ebakisi mwa marge ya likolo mpo na espacement facile uta na ba entrées oyo ezali likolo.

Ba formulaire ya ba handicapés

Bobakisa disabledattribut boolean na entrée moko mpo na kopekisa ba interactions ya mosaleli mpe kosala ete emonana pete.

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

Bakisa disabledattribut na a <fieldset>pona ko désactiver ba contrôles nionso na kati.

Caveat na ba ancres

Ba navigateurs e traité ba contrôles nionso ya forme native ( <input>, <select>, na ba <button>éléments) na kati ya a <fieldset disabled>comme désactivé, epekisaka ba interactions ya clavier na souris na bango.

Kasi, soki formulaire na yo ezali mpe na biloko oyo ezali lokola bouton oyo esalemi na kolanda bamposa na yo lokola <a ... class="btn btn-*">, bakopesa yango kaka lolenge ya pointer-events: none. Ndenge emonisami na eteni oyo elobeli état désactivé mpo na ba boutons (mpe mingimingi na eteni moke mpo na ba éléments ya anchor), propriété oyo ya CSS ezali naino standardisé te mpe esungami mobimba te na Internet Explorer 10. Ba contrôles oyo esalemi na anchor ekozala mpe kaka bongo focusable mpe ekoki kosala na nzela ya clavier. Esengeli o modifier manuellement ba contrôles oyo na kobakisa tabindex="-1"mpo na kopekisa yango kozua focus mpe aria-disabled="disabled"ko signaler état na yango na ba technologies d’assistance.

Bokokani ya navigateur croisé

Atako Bootstrap ekosalela ba styles oyo na ba navigateurs nionso, Internet Explorer 11 mpe na se esimbaka mobimba te disabledattribut na <fieldset>. Salelá JavaScript oyo obongisi mpo na kokanga esika oyo ozali kosala na ba navigateurs oyo.

Bondimisi ya mosala

Pesa makanisi ya motuya, oyo ekoki kosala na basaleli na yo na bondimi ya formulaire HTML5– oyo ezali na ba navigateurs na biso nyonso oyo tosungami . Pona na kati ya ba réactions ya validation par défaut ya navigateur, to salela ba messages personnalisés na ba classes na biso oyo etongami na kati mpe JavaScript ya démarrage.

Toyebi ete na ntango oyo ba styles ya validation personnalisée ya côté client mpe ba toli ya bisaleli ezali accessible te, puisque ezali exposés te na ba technologies ya lisungi. Ntango tozali kosala na solution, tokopesa toli ya kosalela option ya côté serveur to méthode ya validation ya navigateur par défaut.

Validation ya groupe ya entrée

Ba groupes ya entrée bazalaka na difficulté na ba styles ya validation, malheureusement. Recommandation na biso ezali ya kotia ba messages ya retour lokola ba éléments frères ya .input-groupoyo ezali na .is-{valid|invalid}. Kotia ba messages ya ba réactions na kati ya ba groupes ya entrée ebukaka border-radius. Tala likambo oyo ya kosilisa likambo yango .

Ndenge oyo esalaka

Tala ndenge validation ya formulaire esalaka na Bootstrap:

  • Validation ya formulaire HTML esalemi na nzela ya ba pseudo-classes mibale ya CSS, :invalidmpe :valid. Etaleli <input>, <select>, mpe <textarea>biloko.
  • Bootstrap esali ba styles ya :invalidmpe :validna classe ya moboti .was-validated, mingi mingi esalelamaka na <form>. Soki te, esika nyonso oyo esengeli kozanga motuya ekolakisama lokola oyo ezali na ntina te na bokɔti ya lokasa. Na ndenge yango, okoki kopona ntango nini okofungola yango (mingimingi nsima ya komeka kotinda formulaire).
  • Mpo na kozongisa lolenge ya komonana ya formulaire (ndakisa, na likambo ya botindiki ya formulaire dynamique na kosalelaka AJAX), longola .was-validatedkelasi na<form> lisusu nsima ya kotinda.
  • Lokola fallback, .is-invalidmpe .is-validba classes ekoki kosalelama na esika ya ba pseudo-classes mpo na validation ya côté serveur . Bazali kosɛnga te .was-validatedkelasi ya baboti.
  • Na tina ya ba contraintes na ndenge CSS esalaka, tokoki te (na tango oyo) kosalela ba styles na a <label>oyo eyaka liboso ya contrôle ya formulaire na DOM sans aide ya JavaScript personnalisé.
  • Ba navigateurs nionso ya mikolo oyo esungaka API ya validation ya contrainte , série ya ba méthodes ya JavaScript pona ko valider ba contrôles ya formulaire.
  • Ba messages ya ba réactions ekoki kosalela ba défauts ya navigateur (ekeseni mpo na navigateur moko na moko, mpe ekoki kozala na style te na nzela ya CSS) to ba styles na biso ya ba réactions personnalisés na HTML mpe CSS ya kobakisa.
  • Okoki kopesa ba messages ya validité personnalisé na setCustomValidityna JavaScript.

Na makanisi wana, talelá ba démonstrations oyo elandi mpo na ba styles na biso ya validation ya formulaire personnalisé, ba classes ya côté serveur oyo okoki kopona, mpe ba défauts ya navigateur.

Ba styles oyo esalemi na kolanda bamposa ya bato

Mpo na ba messages ya validation ya formulaire ya Bootstrap personnalisé, ekosenga obakisa novalidateattribut boolean na <form>. Yango e désactiver ba conseils ya retour par défaut ya navigateur, kasi epesaka kaka accès na ba API ya validation ya formulaire na JavaScript. Meká kotinda formulaire oyo ezali awa na nse; JavaScript na biso ekokanga bouton ya kotinda mpe ekopesa yo makanisi. Ntango ozali komeka kotinda, okomona :invalidmpe :validmitindo oyo esalelami na ba contrôles ya formulaire na yo.

Ba styles ya ba retours personnalisés esalelaka ba couleurs personnalisées, ba frontières, ba styles ya focus, na ba icônes ya fond pona ko communiquer malamu ba réactions. Ba icônes ya fond ya <select>s ezali kaka na .custom-select, mpe te .form-control.

    )
  ),
  $form-validation-states
);

// Loop from `_forms.scss`
// Any modifications to the above Sass map will be reflected in your compiled
// CSS via this loop.
@each $state, $data in $form-validation-states {
  @include form-validation-state($state, map-get($data, color), map-get($data, icon));
}
