Alternativas ad pittacia occultata

Technologiae adiutrices sicut lectorum tegumentum laborantes cum formis tuis habebunt si pittacium non pro singulis initus includas. .sr-onlyAd has inlineas formas, pittacia classium utentes celare potes . Aliae insuper sunt methodi praebendi pittacium technologiarum adiuvativarum, ut sunt aria-label, aria-labelledbyseu titleattributum. Si nullae ex his adsunt, technologiae adiutrices uti possunt placeholderattributo, si adsint, uti, sed notare usum placeholdersubstitutionis aliis methodis titulatis non admoneri.

Auxilium text

Clausus gradus ope textus in formis creari potest utens .form-text(antea ut .help-blockin v3). Textus ope inline flexibiliter impleri potest utens quolibet inlineo HTML elementi et utilitate classium similibus .text-muted.

Textus cum forma controls iungens auxilium

Auxilium textus debet explicite coniungi cum forma temperantiae quod pertinet ad usus aria-describedbyattributi. Hoc efficiet ut technologiae adiutrices - sicut lectores tegumentum - hunc textum adiuvent annuntient cum usor tendit vel imperium intrat.

Auxilium textus infra inputs dici potest cum .form-text. Hoc genus includit display: blocket addit aliquam marginem top pro facili spatio ab inputibus supra.

Tessera tua 8-20 characteres longus esse debet, litteras et numeros continent, nec spatia, characteres speciales, vel emoji continere debet. 
<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>

Inline textus uti potest quodlibet elementum typicum inline HTML (sit a <small>, <span>vel aliquid aliud) cum nihil aliud quam genus utilitatis.

Oportet 8-20 characteres tempore. 
<form class="form-inline">
  <div class="form-group">
    <label for="inputPassword6">Password</label>
    <input type="password" id="inputPassword6" class="form-control mx-sm-3" aria-describedby="passwordHelpInline">
    <small id="passwordHelpInline" class="text-muted">
      Must be 8-20 characters long.
    </small>
  </div>
</form>

Debilitatum formae

Boolean disabledattributum addere in initus ad impediendum interationes usoris ne leviores appareant.

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

Adde quod omne imperium intus inactivandi disabledattributum est .<fieldset>

<form>
  <fieldset disabled>
    <legend>Disabled fieldset example</legend>
    <div class="form-group">

      <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">

    <div class="form-group">
      <label for="disabledSelect">Disabled select menu</label>

    <div class="form-group">

Caveat anchoris

Navigatores omnes nativa forma moderamina (,, et elementa) intus quasi debiles tractant <input>, <select>impediens <button>tam <fieldset disabled>claviaturas quam mus interationes.

Attamen, si forma tua contineat consue- tudinem elementorum qualitatum <a ... class="btn btn-*">, haec solum stylus tradendus est pointer-events: none. Sicut notatum est in sectione de statu debilitatum pro globulis (et speciatim in sub-sectione pro elementis sublatis), haec proprietas CSS nondum normatum est nec plene in Penitus Rimor sustinetur 10. Moderatores ancorae fundatae etiam adhuc erunt focusable et operabilis utens tincidunt. Haec moderamina manually modificare debes, addendo tabindex="-1"ne umbilicum recipiant et aria-disabled="disabled"statum suum ad technologias adiuvandas designent.

Crucem pasco convenientiam

Dum Bootstrap hos stylos in omnibus navigatoribus adhibebit, Internet Explorer 11 et infra non plene disabledattributum in a <fieldset>. Utere consuetudine JavaScript ad disable campum in his navigatoribus.

Validation

Praebere pretiosos, actuosos opiniones ad tuos usores cum HTML5 forma validation-, available in omnibus navigatoribus nostris suffragantibus . Eligite ex navigatro validationum default feedback, vel nuntia consuetudinem efficiendi cum nostris in classibus constructis et JavaScript starter.

Scimus in hac parte huius consuetudinis validationum genera et instrumenta instrumenta adiri non esse, cum technologiae adiutrices adiuvandae non sint expositae. Dum solutionem laboramus, commendamus vel optione ministrantis parte utens vel methodo sanationis defaltae navigatoris.

Quomodo facitur

Ecce quomodo sanatio forma cum Bootstrap operatur:

  • Forma sanationis HTML applicatur per duas pseudo-classes CSS, :invalidet :valid. Applicat ad <input>, <select>, et <textarea>elementa.
  • Bootstrap ambitus :invalidet :validstilos ad genus parentis .was-validated, ad usitate applicari solet <form>. Alioquin quis campus requiritur sine valore paginae onus in pagina invalidum ostendit. Hoc modo eligat licet eos movere (typice post formam subiectionis tentatur).
  • Reponere speciem formae (exempli gratia, in casu dynamicae formae submissionibus utens AJAX), .was-validatedgenus e <form>rursus post submissionem removendum.
  • Pro fallagia, .is-invalidet .is-validclasses loco pseudo-classum adhiberi possunt pro parte sanationis server . Non indigent .was-validatedparentis genere.
  • Ob angustias quomodo opera CSS, non possumus (nunc) stylos applicare ad <label>formam in DOM praecedente sine auxilio consuetudinis JavaScript.
  • Omnes moderni navigatores angustiam validation API sustentant , series JavaScript methodi ad formam moderantis confirmandam.
  • Feedback nuntiis potest uti defaltis navigatoris (pro unoquoque navigatro diversum, et per CSS inexplicabile) vel more nostro videre stilos additis HTML et CSS.
  • Mandata consuetudo validitatem praebere potes setCustomValidityin JavaScript.

In hoc animo considera sequentia demos pro more nostro genera sanationis formare, servo libitum classium laterum, defaltis navigare.

More styles

Pro consuetudine Bootstrap epistulae sanationis formant, necesse est tibi novalidateattributum boolean addere tuo <form>. Hoc navigatrum defalta disables feedback instrumentorum instrumentorum, sed tamen accessum praebet formae sanationis APIs in JavaScript. Formam infra subiicere conantur; nostrum JavaScript intercipiet tesseram submittere et feedback tibi nullam. Cum subire conanti, videbis formas :invalidet :validgenera admoveri imperiorum.

Consuetudinem feedback styles ad consuetudinem colorum, fines, stilos umbilicos, et icones colorum ad meliores opiniones communicandas. Icones Background pro <select>s tantum in promptu sunt .custom-select, nec .form-control.

Commendamus utendo validationi clientelam, sed si latus sanationis exigis servo, indicare potes agros invalidos et validos formare .is-invalidet .is-valid. Nota quod .invalid-feedbacketiam his generibus suffragatur.

Pro agris invalidis, ut irritum feedback/errorem nuntium associatur cum forma agri utendi pertinet aria-describedby. Hoc attributum plus quam unum idreferri permittit, si campus iam indicat textum formae additae.
