Tsalwa ra mpfuneto

Tsalwa ra mpfuneto ra xiyimo xa xibokisana eka tifomo ri nga endliwa hi ku tirhisa .form-text(khale a ri tiviwa tanihi .help-blockeka v3). Tsalwa ra mpfuneto wa le ndzeni ka layini ri nga tirhisiwa hi ku cinca-cinca hi ku tirhisa xiaki xihi na xihi xa HTML xa le ndzeni ka layini na titlilasi ta vukorhokeri to fana na .text-muted.

Kambe, loko fomo ya wena yi tlhela yi katsa swiaki leswi fanaka ni buti ya ntolovelo swo tanihi <a ... class="btn btn-*">, leswi swi ta nyikiwa ntsena xitayili xa pointer-events: none. Hilaha swi kombisiweke hakona eka xiyenge lexi vulavulaka hi xiyimo lexi nga tirhiki xa swikomba-nkarhi (naswona hi ku kongoma eka xiyengentsongo xa swiaki swa anchor), nhundzu leyi ya CSS a yi si ringanisiwa naswona a yi seketeriwi hi ku helela eka Internet Explorer 10. Vulawuri lebyi sekeriweke eka anchor na byona byi ta va bya ha ri tano yi kota ku kongomisa naswona yi tirha hi ku tirhisa khibhodi. U fanele ku cinca hi voko vulawuri lebyi hi ku engetela tabindex="-1"ku byi sivela ku amukela ku kongomisa na aria-disabled="disabled"ku kombisa xiyimo xa byona eka thekinoloji yo pfuneta.

Ku fambisana ka cross-browser

Loko Bootstrap yi ta tirhisa switayele leswi eka swihlamusela-marito hinkwaswo, Internet Explorer 11 na le hansi a yi seketeli hi ku helela disabledxihlawulekisi eka <fieldset>. Tirhisa JavaScript ya ntolovelo ku tshikisa fieldset eka swihlamusela-marito leswi.

Ku tiyisisiwa ka swilo

Nyika vuyelo bya nkoka, lebyi nga tekiwaka goza eka vatirhisi va wena hi ku tiyisisiwa ka fomo ya HTML5– leyi kumekaka eka swihlamusela-marito swa hina hinkwaswo leswi seketeriwaka . Hlawula eka vuyelo bya ku tiyisisa bya xiviri bya browser, kutani u tirhisa marungula ya ntolovelo hi titlilasi ta hina leti akiweke endzeni na JavaScript yo sungula.

Ha swi tiva leswaku sweswi switayele swa ku tiyisisiwa ka ntolovelo swa tlhelo ra xilayenti na switsundzuxo swa switirhisiwa a swi fikeleleki, tanihileswi swi nga hlanganangiki na thekinoloji yo pfuneta. Loko hi ri karhi hi tirha eka ntlhantlho, hi nga ringanyeta ku tirhisa nhlawulo wa le tlhelo ra sevha kumbe ndlela ya ku tiyisisa xihlamusela-marito xa ntolovelo.

Ndlela leyi swi tirhaka ha yona

Hi leyi ndlela leyi ku tiyisisiwa ka fomo ku tirhaka ha yona hi Bootstrap:

  • Ku tiyisisiwa ka fomo ya HTML ku tirhisiwa hi ku tirhisa titlilasi timbirhi ta vuxisi ta CSS, :invalidna :valid. Yi tirha eka <input>, <select>, na <textarea>swiaki.
  • Bootstrap yi hlanganisa switayele swa :invalidna :valideka tlilasi ya mutswari .was-validated, hi ntolovelo swi tirhisiwa eka <form>. Handle ka sweswo, nsimu yihi na yihi leyi lavekaka leyi nga riki na ntikelo yi kombisa tanihi leyi nga tirhiki eka ku layicha pheji. Hi ndlela leyi, u nga ha hlawula leswaku u ta ti tirhisa rini (hi ntolovelo endzhaku ka loko ku ringetiwile ku rhumela fomo).
  • Ku tlhela u veka xivumbeko xa fomo (xikombiso, eka xiyimo xa ku rhumeriwa ka fomo leyi cinca-cincaka hi ku tirhisa AJAX), susa .was-validatedtlilasi eka <form>nakambe endzhaku ko rhumela.
  • Tanihi fallback, .is-invalidnaswona .is-validtitlilasi ti nga tirhisiwa ematshan’wini ya titlilasi ta vuxisi ta ku tiyisisiwa ka tlhelo ra sevha . A va lavi .was-validatedtlilasi ya mutswari.
  • Hikwalaho ka swipimelo eka ndlela leyi CSS yi tirhaka ha yona, a hi nge (sweswi) tirhisa switayele eka a <label>leyi taka emahlweni ka vulawuri bya fomo eka DOM handle ko pfuniwa hi JavaScript ya ntolovelo.
  • Swihlamusela-marito hinkwaswo swa manguva lawa swi seketela API ya ku tiyisisa swipimelo , nxaxamelo wa tindlela ta JavaScript to tiyisisa vulawuri bya fomo.
  • Mahungu ya vuyelo ma nga ha tirhisa swilo leswi nga riki swa xiviri swa xihlamusela-marito (leswi hambaneke eka xihlamusela-marito xin’wana ni xin’wana, naswona swi nga cinciwi hi ku tirhisa CSS) kumbe switayele swa hina swa vuyelo lebyi endleriweke hi ku tirhisa HTML ni CSS leyi engetelekeke.
  • U nga ha nyika marungula ya ntiyiso ya ntolovelo na setCustomValidityeka JavaScript.

Hi ku tsundzuka sweswo, xiya ti-demo leti landzelaka ta switayele swa hina swa ku tiyisisiwa ka fomo ya ntolovelo, titlilasi ta le tlhelo ra sevha leti nga hlawuriwa, ni swilo leswi nga riki swa xiviri swa xihlamusela-marito.

Switayili swa ntolovelo

Eka marungula ya ku tiyisisa fomo ya Bootstrap ya ntolovelo, u ta lava ku engetela novalidatexihlawulekisi xa boolean eka <form>. Leswi swi tshikisa switsundzuxo swa vuyelo bya xiviri bya xihlamusela-marito, kambe swa ha nyika mfikelelo eka ti-API ta ku tiyisisa fomo eka JavaScript. Ringeta ku rhumela fomo leyi nga laha hansi; JavaScript ya hina yi ta kavanyeta buti yo rhumela ivi yi ku hundzisela vuxokoxoko. Loko u ringeta ku rhumela, u ta vona :invalidna :validswitayele swi tirhisiwa eka vulawuri bya wena bya fomo.

Switayili swa mbuyelo wa ntolovelo swi tirhisa mihlovo ya ntolovelo, mindzilakano, switayele swa ku kongomisa, na swifaniso swa le ndzhaku ku hlanganisa mbuyelo ku antswa. Swifaniso swa le ndzhaku swa <select>s swi kumeka ntsena hi .custom-select, naswona a hi .form-control.

Ku endla swilo hi ku landza swilaveko swa wena

Swiyimo swa ku tiyisisa swi nga endliwa hi ku tirhisa Sass hi $form-validation-statesmepe. Yi kumeka eka fayili ya hina _variables.scss, mepe lowu wa Sass wu looped over ku tumbuluxa swiyimo swa default valid/ invalidvalidation. Ku katsiwile mepe lowu pfanganisiweke wa ku cinca muvala ni xifaniso xa tiko rin’wana ni rin’wana. Hambileswi ku nga riki na swifundzha swin’wana leswi seketeriwaka hi swihlamusela-marito, lava tirhisaka switayele swa ntolovelo va nga engetela hi ku olova vuyelo bya fomo lebyi rharhanganeke swinene.

Hi kombela u xiya leswaku a hi bumabumeli ku cinca mimpimo leyi handle ko tlhela u cinca form-validation-statemixin.

// Sass map from `_variables.scss`
// Override this and recompile your Sass to generate different states
$form-validation-states: map-merge(

  ),
  $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));

Tifomo ta ntolovelo

Ku kuma ku cinca loku engetelekeke swinene ni ku ringanana ka xihlamusela-marito xo tsemakanya, tirhisa swiaki swa hina swa fomo leswi endleriweke hi ku helela ku siva swilo leswi nga riki swa xiviri swa xihlamusela-marito. Ti akiwile ehenhla ka ximaki xa semantiki na lexi fikelelaka, kutani i ku cinca loku tiyeke eka vulawuri byihi na byihi bya xivumbeko xa ntolovelo.

Mabokisi yo kambela ni swiya-ni-moya

Bokisi rin’wana na rin’wana ro kambela na radio <input>na ku <label>hlanganisiwa swi phutseriwe hi a <div>ku endla vulawuri bya hina bya ntolovelo. Hi xivumbeko, leyi i ndlela leyi fanaka ni ya hina ya xiviri .form-check.

Hi tirhisa xihlawulekisi xa vamakwerhu ( ~) eka <input>swifundzha swa hina hinkwaswo—ku fana na :checked—ku xitayili kahle xikombiso xa hina xa xivumbeko xa ntolovelo. Loko hi hlanganisiwa na .custom-control-labeltlilasi, hi nga tlhela hi endla xitayili xa tsalwa ra nchumu wun’wana na wun’wana hi ku ya hi xiyimo xa <input>'s.

Hi fihla xihlawulekisi <input>hi opacityna ku tirhisa .custom-control-labelku aka xikombiso lexintshwa xa xivumbeko xa ntolovelo ematshan'wini ya xona hi ::beforena ::after. Khombo ra kona a hi nge swi koti ku aka custom one from just the <input>hikuva CSS's contenta yi tirhi eka element yoleyo.

Eka swiyimo leswi kamberiweke, hi tirhisa swifaniso swa SVG leswi nghenisiweke swa base64 ku suka eka Open Iconic . Leswi swi hi nyika vulawuri lebyinene bya ku endla switayele na ku veka swiyimo eka swihlamusela-marito na switirhisiwa.

Mabokisi yo kambela

Mabokisi yo kambela ya ntolovelo ya nga tlhela ya tirhisa :indeterminatetlilasi ya vuxisi loko yi vekiwile hi voko hi ku tirhisa JavaScript (a ku na xihlawulekisi xa HTML lexi kumekaka xo xi boxa).

Loko u tirhisa jQuery, nchumu wo fana na lowu wu fanele wu enela:

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

Track (ndhavuko) na thumb (nhlayo) havumbirhi bya swona swi endliwe hi xitayili leswaku swi vonaka swi fana eka swihlamusela-marito hinkwaswo. Tanihi leswi ntsena IE na Firefox va seketelaka ku “tata” track ya vona ku suka eximatsini kumbe exineneni xa xikunwana tanihi ndlela yo kombisa hi mahlo nhluvuko, sweswi a hi yi seketeli.

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

Switirhisiwa swa range swi na mimpimo leyi nga kongomangiki ya minna max— 0na 100, hi ku landzelelana. U nga ha boxa mimpimo leyintshwa ya lava tirhisaka swihlawulekisi swa minna .max

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

By default, range inputs “snap” to integer values. To change this, you can specify a step value. In the example below, we double the number of steps by using step="0.5".

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

File browser

The recommended plugin to animate custom file input: bs-custom-file-input, that’s what we are using currently here in our docs.

The file input is the most gnarly of the bunch and requires additional JavaScript if you’d like to hook them up with functional Choose file… and selected file name text.

<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 with SCSS

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>

U ta fanela ku veka ririmi ra tsalwa ra wena (kumbe murhi lowutsongo wa rona) hi ndlela leyinene leswaku tsalwa lerinene ri ta kombisiwa. Leswi swi nga endliwa hi ku tirhisa xihlawulekisi langeka elemente <html>kumbe nhloko ya Content-LanguageHTTP , exikarhi ka tindlela tin’wana.

Ku hundzuluxela kumbe ku lulamisa tintambhu hi HTML

Bootstrap yi tlhela yi nyika ndlela yo hundzuluxela tsalwa ra “Browse” eka HTML hi data-browsexihlawulekisi lexi nga engeteriwa eka lebula ya ku nghenisa ya ntolovelo (xikombiso hi Xidachi):

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