Swivumbeko

Swikombiso na swiletelo swa matirhiselo ya switayele swa vulawuri bya tifomo, swihlawulekisi swa layout, na swiphemu swa ntolovelo swo tumbuluxa tifomo to hambana hambana.

Nkatsakanyo

Swilawuri swa fomo swa Bootstrap swi andlala eka switayele swa hina swa fomo leswi Rebooted hi titlilasi. Tirhisa titlilasi leti ku hlawula eka swikombiso swa tona leswi endleriweke ku hundzuluxela loku nga cincekiki eka swihlamusela-marito ni switirhisiwa.

Tiyisisa leswaku u tirhisa typexihlawulekisi lexi faneleke eka swingheniso hinkwaswo (xikombiso, emaileka adirese ya imeyili kumbe numbereka vuxokoxoko bya tinhlayo) ku tirhisa vulawuri bya swingheniso leswintshwa swo fana na ku tiyisisiwa ka imeyili, ku hlawula tinomboro, na swin’wana.

Hi lexi xikombiso xo hatlisa xo kombisa switayele swa xivumbeko xa Bootstrap. Tshama u ri karhi u hlaya ku kuma matsalwa ya titlilasi leti lavekaka, maendlelo ya fomo, na swin’wana.

Xitsundzuxo lexi nga ni tinsoma

Hi ku tiyimisela, swihlamusela-marito swi ta khoma vulawuri hinkwabyo bya xivumbeko xa ntumbuluko ( <input>, <select>na <button>swiaki) endzeni ka a <fieldset disabled>tanihi leswi nga tirhiki, swi sivela ku tirhisana ka khibhodi na mbeva eka swona. Kambe loko fomo ya wena yi tlhela yi katsa <a ... class="btn btn-*">swiaki, 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, naswona a yi nge siveli vatirhisi va khibhodi ku va tano ku kota ku kongomisa kumbe ku tirhisa swihlanganisi leswi. Kutani leswaku u hlayiseka, tirhisa JavaScript leyi endleriweke wena ku tshikisa swihlanganisi swo tano.

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.

Sweswi hi ringanyeta ku tirhisa switayele swa ku tiyisisa swa ntolovelo, tanihileswi marungula ya ku tiyisisa ya xiviri ya xihlamusela-marito xa ntumbuluko ma nga tshamisekangiki ku hlangana na thekinoloji yo pfuneta eka swihlamusela-marito hinkwaswo (ngopfu-ngopfu, Chrome eka desktop na movha).

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(
  (
    "valid": (

  ),
  $form-validation-states

// Loop from `_forms.scss`
// Any modifications to the above Sass map will be reflected in your compiled
// CSS via this loop.

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

<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>

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)

Swiya-ni-moya

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

Swiwitsi

Swiwitsi swi na mfungho wa bokisi ro kambela ra ntolovelo kambe swi tirhisa .custom-switchtlilasi ku humesa swiwitsi swo cinca-cinca. Swiwitsi na swona swi seketela disabledxihlawulekisi.

Mpimo

Endla <input type="range">vulawuri bya ntolovelo hi .custom-range. 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>

Xihlamusela-marito xa fayili

Plugin leyi ringanyetiweke ku endla leswaku ku nghenisiwa ka fayili ya ntolovelo yi hanya: bs-custom-file-input , hi swona leswi hi swi tirhisaka sweswi laha eka ti-doc ta hina.

Ku nghenisa fayili i gnarly swinene eka ntlhambi naswona ku lava JavaScript yo engetela loko u lava ku va khoma hi ntirho Hlawula fayili... na tsalwa ra vito ra fayili leri hlawuriweke.

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFile">

Hi tumbeta fayili ya ntolovelo <input>hi ku tirhisa opacitynaswona ematshan’weni ya sweswo hi xitayili xa <label>. Batani yi endliwa no vekiwa hi ::after. Xo hetelela, hi tivisa a widthand heighton the<input> for proper spacing for surrounding content.

Ku hundzuluxela kumbe ku lulamisa tintambhu hi SCSS

Tlilasi :lang()ya vuxisi yi tirhisiwa ku pfumelela ku hundzuluxeriwa ka tsalwa ra “Browse” hi tindzimi tin’wana. Tlula kumbe ku engetela swilo leswi nghenisiweke eka $custom-file-textxihlawulekisi xa Sass hi thegi ya ririmi leyi faneleke na tintambhu ta laha kaya. Tintambhu ta Xinghezi ti nga endliwa hi ndlela leyi fanaka. Hi xikombiso, hi leyi ndlela leyi munhu a nga engetelaka vuhundzuluxeri bya Xipaniya ha yona (khodi ya ririmi ra Xipaniya i es):

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

Hi leswi swi lang(es)tirhaka eka ku nghenisa ka fayili ya ntolovelo ya vuhundzuluxeri bya Xipaniya:
