Iifom

Imizekelo kunye nezikhokelo zokusetyenziswa kweendlela zokulawula iifom, iinketho zokubeka, kunye namacandelo angokwezifiso ekudaleni iintlobo ezininzi zeefom.

Isishwankathelo

Ulawulo lwefom ye-Bootstrap yandisa kwizimbo zethu zefom eQaliswe ngokutsha ngeeklasi. Sebenzisa ezi klasi ukungena kwiziboniso zazo ezilungiselelwe unikezelo olungaguquguqukiyo kuzo zonke iibhrawuza kunye nezixhobo.

Qinisekisa ukusebenzisa uphawu olufanelekileyo typekuwo onke amagalelo (umzekelo, emailidilesi ye-imeyile okanye numberngolwazi lwamanani) ukuthatha ithuba lolawulo lwamagalelo amatsha njengesiqinisekiso se-imeyile, ukukhetha amanani, nokunye.

Nanku umzekelo okhawulezayo ukubonisa izimbo zeBootstrap. Gcina ufundela amaxwebhu kwiiklasi ezifunekayo, uyilo lwefom, kunye nokunye.

<form>
  <div class="form-group">
    <label for="exampleInputEmail1">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp" placeholder="Enter email">
    <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
  </div>
  <div class="form-group">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
  </div>
  <div class="form-group form-check">
    <input type="checkbox" class="form-check-input" id="exampleCheck1">
    <label class="form-check-label" for="exampleCheck1">Check me out</label>
  </div>
  <button type="submit" class="btn btn-primary">Submit</button>
</form>

Ulawulo lwefom

Ulawulo lweefom zombhalo-njengo- <input>s, <select>s, kunye no <textarea>-s-zibhalwa kunye .form-controlneklasi. Okubandakanyiweyo zizitayile zenkangeleko jikelele, imeko ekugxilwe kuyo, ubungakanani, kunye nokunye.

Qiniseka ukuba uphonononga iifom zethu zesiko ukuqhubela phambili isimbo <select>s.

<form>
  <div class="form-group">
    <label for="exampleFormControlInput1">Email address</label>
    <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="[email protected]">
  </div>
  <div class="form-group">
    <label for="exampleFormControlSelect1">Example select</label>
    <select class="form-control" id="exampleFormControlSelect1">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </div>
  <div class="form-group">
    <label for="exampleFormControlSelect2">Example multiple select</label>
    <select multiple class="form-control" id="exampleFormControlSelect2">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </div>
  <div class="form-group">
    <label for="exampleFormControlTextarea1">Example textarea</label>
    <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
  </div>
</form>

Kumagalelo efayile, tshintshela .form-controlkwi .form-control-file.

<form>
  <div class="form-group">
    <label for="exampleFormControlFile1">Example file input</label>
    <input type="file" class="form-control-file" id="exampleFormControlFile1">
  </div>
</form>

Ubungakanani

Seta ubude usebenzisa iiklasi ezifana .form-control-lgkunye .form-control-sm.

<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm">

<select class="form-control form-control-lg">
  <option>Large select</option>
</select>
<select class="form-control">
  <option>Default select</option>
</select>
<select class="form-control form-control-sm">
  <option>Small select</option>
</select>

Funda uqhubeleke

Yongeza readonlyuphawu lwe boolean kwigalelo ukunqanda ukulungiswa kwexabiso legalelo. Amagalelo okufunda kuphela abonakala ekhaphukhaphu (njengamagalelo avaliweyo), kodwa gcina ikhesa esemgangathweni.

<input class="form-control" type="text" placeholder="Readonly input here…" readonly>

Funda kuphela isicatshulwa esicacileyo

Ukuba ufuna ukuba <input readonly>nezinto kwimo yakho ezibhalwe njengombhalo ongenanto, sebenzisa .form-control-plaintextiklasi ukususa isimbo sommandla wefomu engagqibekanga kwaye ugcine umda ochanekileyo kunye nokhupho.

<form>
  <div class="form-group row">
    <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
    <div class="col-sm-10">
      <input type="text" readonly class="form-control-plaintext" id="staticEmail" value="[email protected]">
    </div>
  </div>
  <div class="form-group row">
    <label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
    <div class="col-sm-10">
      <input type="password" class="form-control" id="inputPassword" placeholder="Password">
    </div>
  </div>
</form>

<form class="form-inline">
  <div class="form-group mb-2">
    <label for="staticEmail2" class="sr-only">Email</label>
    <input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="[email protected]">
  </div>
  <div class="form-group mx-sm-3 mb-2">
    <label for="inputPassword2" class="sr-only">Password</label>
    <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
  </div>
  <button type="submit" class="btn btn-primary mb-2">Confirm identity</button>
</form>

Uluhlu lweeNgeniso

Cwangcisa amagalelo oluhlu olusongelo oluthe tye usebenzisa .form-control-range.

<form>
  <div class="form-group">
    <label for="formControlRange">Example Range input</label>
    <input type="range" class="form-control-range" id="formControlRange">
  </div>
</form>

Iibhokisi zokutshekisha kunye noonomathotholo

Iibhokisi zokukhangela ezihlala zikhona kunye nonomathotholo ziphuculwe ngoncedo lwe .form-check, iklasi enye yazo zombini iindidi zegalelo eziphucula ubeko nokuziphatha kwezinto zabo ze HTML . Iibhokisi zokukhangela zezokukhetha enye okanye iinketho ezininzi kuluhlu, ngelixa oonomathotholo bezokukhetha ukhetho olunye kwabaninzi.

Iibhokisi zokukhangela ezikhubazekileyo kunye nonomathotholo ziyaxhaswa, kodwa ukubonelela not-allowedngekhesa kwihover yomzali <label>, kuya kufuneka udibanise disableduphawu kwi .form-check-input. Uphawu loyelelwano olukhubazekileyo luya kusebenzisa umbala olula ukunceda ukubonisa ubume begalelo.

Iibhokisi zokutshekisha kunye nosetyenziso lweerediyo zakhiwe ukuxhasa ukuqinisekiswa kwefomu esekwe kwi-HTML kunye nokubonelela ngeelebhile ezimfutshane, ezifikelelekayo. Ngaloo ndlela, <input>imiz kunye nemizalwane yethu <label>zizinto zokuzalana ngokuchaseneyo <input>nengaphakathi <label>. Oku kukwi-verbose kancinane njengoko kufuneka ukhankanye idkunye forneempawu zokunxulumana <input>ne <label>.

Okuhlala kukho (kupakishwe)

Ngokungagqibekanga, naliphi na inani leebhokisi zokukhangela kunye nonomathotholo abazalanayo baya kugcinwa ngokuthe nkqo kwaye zibekwe ngokufanelekileyo nge .form-check.

Uyilo

Kuba iBootstrap isebenza display: blockkwaye width: 100%phantse kulo lonke uhlobo lwethu lolawulo, iifom ziya kuthi ngokungagqibekanga zipakishwe ngokuthe nkqo. Iiklasi ezongezelelweyo zingasetyenziselwa ukuhluka kolu yilo ngokwefom.

Yenza amaqela

Iklasi .form-groupyeyona ndlela ilula yokongeza isakhiwo kwiifom. Ibonelela ngodidi oluguquguqukayo olukhuthaza ukuhlelwa ngokufanelekileyo kweelebhile, ulawulo, isicatshulwa soncedo esikhethwayo, kunye nefomu yokuqinisekisa imiyalezo. Ngokungagqibekanga iyasebenza kuphela margin-bottom, kodwa ithatha izitayile ezongezelelweyo .form-inlinenjengoko kufuneka. Yisebenzise kunye no- <fieldset>s, <div>s, okanye phantse nayiphi na enye into.

<form>
  <div class="form-group">
    <label for="formGroupExampleInput">Example label</label>
    <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
  </div>
  <div class="form-group">
    <label for="formGroupExampleInput2">Another label</label>
    <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
  </div>
</form>

Igridi yefom

Iifom ezinzima ngakumbi zinokukhiwa kusetyenziswa iiklasi zethu zegridi. Sebenzisa ezi kuyilo lweefom ezifuna iikholamu ezininzi, ububanzi obahlukeneyo, kunye nokhetho olongezelelweyo lolungelelwaniso.

<form>
  <div class="row">
    <div class="col">
      <input type="text" class="form-control" placeholder="First name">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Last name">
    </div>
  </div>
</form>

Yenza umqolo

Ungatshintshiselana kwakhona .row, .form-rowumahluko womqolo wethu wegridi osemgangathweni ogqithisela ngaphezulu kwimijelo yoluhlu olumiselweyo loyilo oluqina kunye noluxineneyo ngakumbi.

<form>
  <div class="form-row">
    <div class="col">
      <input type="text" class="form-control" placeholder="First name">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Last name">
    </div>
  </div>
</form>

Uyilo oluntsonkothileyo lunokwenziwa kunye nenkqubo yegridi.

<form>
  <div class="form-row">
    <div class="form-group col-md-6">
      <label for="inputEmail4">Email</label>

        Check me out
      </label>
    </div>
  </div>
  <button type="submit" class="btn btn-primary">Sign in</button>
</form>

Ifom ethe tye

Yenza iifom ezithe tyaba ngegridi ngokudibanisa .rowiklasi ukwenza amaqela kunye nokusebenzisa .col-*-*iiklasi ukucacisa ububanzi beelebhile zakho kunye nolawulo. Qinisekisa ukuba ukongeza .col-form-labelkwi- <label>s yakho ngokunjalo ukuze babekwe ngokuthe nkqo embindini nolawulo lwefom enxulumeneyo.

Ngamanye amaxesha, kuya kufuneka usebenzise i-margin okanye i-padding eziluncedo ukwenza ulungelelwaniso olugqibeleleyo oludingayo. Umzekelo, siyisusile padding-topileyibhile kwirediyo yethu epakishweyo ukuze silungelelanise ngcono isiseko sombhalo.

Ukulinganisa okuzenzekelayo

Umzekelo ongezantsi usebenzisa into eluncedo ye-flexbox ukubeka embindini ngokuthe nkqo imixholo kunye notshintsho .colukuze .col-autoiikholomu zakho zithathe kuphela indawo eninzi njengoko kufuneka. Beka enye indlela, ubukhulu bekholamu ngokwayo ngokusekelwe kwimixholo.

<form>
  <div class="form-row align-items-center">
    <div class="col-auto">
      <label class="sr-only" for="inlineFormInput">Name</label>
      <input type="text" class="form-control mb-2" id="inlineFormInput" placeholder="Jane Doe">
    </div>
    <div class="col-auto">

Iifom zangaphakathi

Sebenzisa .form-inlineiklasi ukubonisa uluhlu lweelebhile, ulawulo lwefom, kunye namaqhosha kumqolo omnye othe tye. Ulawulo lweefomu ngaphakathi kweefom ezingaphakathi komgca ziyohluka kancinci kwiimeko zazo ezisilelayo.

Izilawuli zi display: flex, ziwisa nasiphi na isithuba esimhlophe seHTML kwaye ikuvumela ukuba unikeze ngolawulo lolungelelwaniso ngezithuba kunye nezinto eziluncedo ze - flexbox .
Amaqela olawulo kunye namagalelo afumana width: autoukukhuphela ngaphezulu i-Bootstrap engagqibekanga width: 100%.
Izilawuli zivela kuphela emgceni kwiizibuko zokujonga ubuncinane eziyi-576px ububanzi ukuze kunikwe ingxelo ngeendawo zokujonga ezimxinwa kwizixhobo eziphathwayo.

Kusenokufuneka ukuba ulungise ngesandla ububanzi kunye nolungelelwaniso lolawulo lwefomu nganye kunye nezixhobo zokubeka izithuba (njengoko kubonisiwe ngezantsi). Okokugqibela, qiniseka ukuba uhlala ubandakanya <label>ulawulo lwefom nganye, nokuba ufuna ukuyifihla kwiindwendwe ezingafundi isikrini nge .sr-only.

<form class="form-inline">
  <label class="sr-only" for="inlineFormInputName2">Name</label>
  <input type="text" class="form-control mb-2 mr-sm-2" id="inlineFormInputName2" placeholder="Jane Doe">

  <label class="sr-only" for="inlineFormInputGroupUsername2">Username</label>
  <div class="input-group mb-2 mr-sm-2">
    <div class="input-group-prepend">
      <div class="input-group-text">@</div>
    </div>
    <input type="text" class="form-control" id="inlineFormInputGroupUsername2" placeholder="Username">
  </div>

  <div class="form-check mb-2 mr-sm-2">
    <input class="form-check-input" type="checkbox" id="inlineFormCheck">
    <label class="form-check-label" for="inlineFormCheck">
      Remember me
    </label>
  </div>

  <button type="submit" class="btn btn-primary mb-2">Submit</button>
</form>

Ulawulo lwefom yesiko kunye nokukhetha kuyaxhaswa.

<form class="form-inline">
  <label class="my-1 mr-2" for="inlineFormCustomSelectPref">Preference</label>
  <select class="custom-select my-1 mr-sm-2" id="inlineFormCustomSelectPref">

Iindlela ezizezinye kwiilebhile ezifihliweyo

Itekhnoloji ezincedisayo ezifana nezifundi zesikrini ziya kuba nengxaki kwiifomu zakho ukuba awubandakanyi ileyibhile yalo lonke igalelo. Kwezi fom zangaphakathi, ungazifihla iilebhile usebenzisa .sr-onlyiklasi. Kukho ezinye iindlela ezizezinye zokubonelela ngeleyibhile yeetekhnoloji ezincedisayo, ezifana ne- aria-label, aria-labelledbyokanye titleuphawu. Ukuba akukho nanye kwezi ekhoyo, ubuchwephesha obuncedisayo busenokubhenela ekusebenziseni placeholderuphawu, ukuba lukhona, kodwa qaphela ukuba ukusetyenziswa placeholderkwendawo yezinye iindlela zokuleyibheli akucetyiswa.

Umbhalo woncedo

Isicatshulwa soncedo lwenqanaba lebhlokhi kwiifom zinokudalwa kusetyenziswa .form-text(eyaziwa ngaphambili njenge .help-block-v3). Okubhaliweyo koncedo lwangaphakathi kunokuphunyezwa ngokuguquguqukayo kusetyenziswa nasiphi na isiqalelo se-HTML esingaphakathi kunye neeklasi eziluncedo ezifana .text-muted.

Ukunxulumanisa isicatshulwa soncedo kunye nolawulo lwefom

Isicatshulwa soncedo kufuneka sidityaniswe ngokuthe gca nolawulo lwefom enxulumene nokusebenzisa aria-describedbyuphawu loyelelwano. Oku kuya kuqinisekisa ukuba iitekhnoloji ezincedisayo-ezifana nezifundi zesikrini-ziya kubhengeza lo mbhalo woncedo xa umsebenzisi egxile okanye engena kulawulo.

Umbhalo woncedo ongezantsi kongeniso ungalungiswa nge .form-text. Le klasi ibandakanya display: blockkwaye yongeza umda ophezulu wezithuba ezilula ukusuka kumagalelo angentla.

Inombolo yokuvula Iphasiwedi yakho mayibe nobude obuyi-8-20 oonobumba ubude, iqulathe oonobumba kunye namanani, kwaye mayingaqulathi izithuba, amagama akhethekileyo, okanye i-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>

Okubhaliweyo okungaphakathi kunokusebenzisa nayiphi na into eqhelekileyo engaphakathi kwe HTML isiqalelo (inokuba yi <small>, <span>, okanye enye into) kungekho nto ingaphaya kodidi oluluncedo.

<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>

Iifom ezikhubazekileyo

Yongeza disableduphawu lwe-boolean kwigalelo ukuthintela ukusebenzisana komsebenzisi kwaye ulwenze lubonakale lula.

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

Yongeza disableduphawu ku a <fieldset>ukuvala zonke izilawuli ngaphakathi.

<form>
  <fieldset disabled>
    <div class="form-group">
      <label for="disabledTextInput">Disabled input</label>
      <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
    </div>
    <div class="form-group">
      <label for="disabledSelect">Disabled select menu</label>
      <select id="disabledSelect" class="form-control">
        <option>Disabled select</option>
      </select>
    </div>
    <div class="form-check">
      <input class="form-check-input" type="checkbox" id="disabledFieldsetCheck" disabled>
      <label class="form-check-label" for="disabledFieldsetCheck">
        Can't check this
      </label>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </fieldset>
</form>

Caveat ngeeankile

Ngokungagqibekanga, abakhangeli bazakuthatha lonke uhlobo lolawulo lwendalo ( <input>, <select>kunye <button>nezakhi) ngaphakathi <fieldset disabled>njengokukhubaziweyo, ukuthintela zombini ibhodi yezitshixo kunye nonxibelelwano lwemouse kuzo. Nangona kunjalo, ukuba ifom yakho ikwabandakanya <a ... class="btn btn-*">izinto, ezi ziya kunikwa kuphela isimbo se pointer-events: none. Njengoko kuphawuliwe kwicandelo malunga nemeko ekhubazekileyo yamaqhosha (kwaye ngokukodwa kwicandelo elingaphantsi lezinto ze-ankile), le propati ye-CSS ayikabekwa emgangathweni kwaye ayixhaswanga ngokupheleleyo kwi-Internet Explorer 10, kwaye ayizukuthintela abasebenzisi bebhodi yezitshixo ukuba ekwaziyo ukugxila okanye ukuvula la makhonkco. Ke ukuze ukhuseleke, sebenzisa iJavaScript yesiko ukuvala amakhonkco anjalo.

Ukuhambelana kwebrowser

Ngelixa i-Bootstrap izakusebenzisa ezi zimbo kuzo zonke iibhrawuza, i-Internet Explorer 11 nangaphantsi ayiluxhasi ngokupheleleyo disableduphawu lwe- <fieldset>. Sebenzisa iJavaScript yesiko ukuvala iseti yangaphandle kwezi bhrawuza.

Ukuqinisekiswa

Nikeza ngengxelo ebalulekileyo, esebenzayo kubasebenzisi bakho ngokuqinisekiswa kwefomu yeHTML5- ifumaneka kuzo zonke iibhrawuza zethu ezixhaswayo . Khetha kwingxelo yokuqinisekisa engagqibekanga yesikhangeli, okanye sebenzisa imiyalezo yesiko ngeeklasi ezakhelwe ngaphakathi kunye neJavaScript yokuqalisa.

Ngoku sicebisa ukuba kusetyenziswe izitayile zokuqinisekisa ngokwesiko, njengoko imiyalezo yokuqinisekisa isikhangeli semveli ayisoloko iboniswa kwiitekhnoloji ezincedisayo kuzo zonke izikhangeli (ingakumbi, iChrome kwidesktop nakwiselfowuni).

Ingaba isebenza kanjani

Nantsi indlela ukuqinisekiswa kwefomu kusebenza ngayo ngeBootstrap:

Uqinisekiso lwefom ye-HTML lusetyenziswa ngeeklasi ezimbini zobuxoki zeCSS, :invalidkunye :valid. Isebenza kwi <input>, <select>, kunye <textarea>neziqalelo.
I-Bootstrap imida :invalidkunye :validnezimbo .was-validatedkwiklasi yabazali, ihlala isetyenziswa kwi <form>. Kungenjalo, nayiphi na indawo efunekayo ngaphandle kwexabiso ibonisa njengengasebenziyo kumthwalo wephepha. Ngale ndlela, usenokukhetha ukuba zisebenze nini na (ngokwesiqhelo emva kokuba kuzanywa ukungenisa kwefomu).
Ukusetha kwakhona inkangeleko yefom (umzekelo, kwimeko yokungeniswa kwefomu eguquguqukayo usebenzisa i-AJAX), susa .was-validatediklasi ukusuka <form>kwakhona emva kokungeniswa.
Njengomba wokubuyela umva, .is-invalidkwaye .is-validiiklasi zinokusetyenziswa endaweni yeeklasi zobuxoki zoqinisekiso lwecala lomncedisi . Abafuni .was-validatedklasi yabazali.
Ngenxa yemiqobo kwindlela esebenza ngayo i-CSS, asinako (okwangoku) ukusebenzisa izitayile <label>kuleyo iza phambi kolawulo lwefom kwiDOM ngaphandle koncedo lweJavaScript yesiko.
Zonke iiphequluli zanamhlanje zixhasa umqobo wokuqinisekisa i-API , uthotho lweendlela zeJavaScript zokuqinisekisa ulawulo lwefom.
Imiyalezo yengxelo inokusebenzisa isikhangeli esingagqibekanga (eyahlukileyo kumkhangeli zincwadi ngamnye, kwaye ayinasitayile ngokusebenzisa iCSS) okanye izimbo zethu zengxelo eyongezelelweyo ngeHTML kunye neCSS.
Unokubonelela ngemiyalezo yokuqinisekisa ngokwesiko setCustomValiditykwiJavaScript.

Unaloo nto engqondweni, qwalasela ezi zidemo zilandelayo zeendlela zethu zokuqinisekisa ifom yesiko, iiklasi ezikhethiweyo zeseva, kunye nokungagqibekanga kwesikhangeli.

Izimbo zesiko

Kwimiyalezo yoqinisekiso lwendlela yeBootstrap yesiko, kuya kufuneka udibanise novalidateuphawu lwe boolean kweyakho <form>. Oku kuvala iingcebiso zesixhobo sengxelo yesikhangeli, kodwa isabonelela ngokufikelela kwifomu yoqinisekiso lweAPIs kwiJavaScript. Zama ukungenisa le fomu ingezantsi; yethu iJavaScript iya kuthintela iqhosha lokungenisa kwaye idlulisele ingxelo kuwe.

Xa uzama ukungenisa, uya kubona iindlela :invalidkunye :validnezimbo ezisetyenziswa kulawulo lwakho lwefom.

Qinisekisa ukuba unomzali position: relativeophezu kwayo ukuze abeke incam yesixhobo. Kulo mzekelo ungezantsi, iiklasi zethu zekholomu sezinayo le nto, kodwa iprojekthi yakho inokufuna enye indlela yokuseta.

Iifom eziqhelekileyo

Ukuze wenze ngokwezifiso ngakumbi kunye nokuhambelana kwesikhangeli, sebenzisa izinto zethu zefom yesiko ngokupheleleyo ukuze ubuyisele ukusilela kwesikhangeli. Zakhelwe phezu kwesemantic kunye nophawu olufikelelekayo, ke zilutshintsho oluluqilima lwalo naluphi na ulawulo lwefom olungagqibekanga.

Iibhokisi zokutshekisha kunye noonomathotholo

Ibhokisi nganye yokukhangela kunye nerediyo isongelwe <div>kunye nomntakwenu <span>ukwenza ulawulo lwethu lwesiko <label>kunye nesicatshulwa esikhaphayo. Ngokwesakhiwo, le yindlela efanayo neyethu engagqibekanga .form-check.

Sisebenzisa umkhethi wabazalwana ( ~) kuwo onke <input>amazwe ethu-nje- :checkedukulungisa ngokufanelekileyo isalathisi sethu sefom yesiko. Xa zidityaniswe .custom-control-labelneklasi, singenza kwakhona isimbo sokubhaliweyo kumba ngamnye ngokusekelwe <input>kwimeko.

Sifihla okungagqibekanga <input>kunye opacitykwaye sisebenzise .custom-control-labelukwakha isalathi sefomu yesiko esitsha endaweni yaso ::beforekunye ::after. Ngelishwa asikwazi ukwakha isiko ukusuka nje <input>ngenxa yokuba i-CSS contentayisebenzi kuloo nto.

Kwiimeko ezikhangelweyo, sisebenzisa ii-icon ze-SVG ezizinzisiweyo ze-base64 ukusuka kwi- Open iconic . Oku kusinika olona lawulo lulungileyo lwesitayile kunye nokubeka kwindawo kuzo zonke iibhrawuza kunye nezixhobo.

Iibhokisi zokukhangela

Khangela le bhokisi yokukhangela yesiko

<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>

Iibhokisi zokukhangela eziqhelekileyo zinokusebenzisa :indeterminateudidi lwepseudo xa lucwangciswe ngesandla ngeJavaScript (akukho phawu loyelelwano lukhoyo lweHTML lokuyikhankanya).

Khangela le bhokisi yokukhangela yesiko

Ukuba usebenzisa i-jQuery, into efana nale kufuneka yanele:

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

Uluhlu

Yenza <input type="range">ulawulo lwesiko nge .custom-range. Ingoma (imvelaphi) kunye nobhontsi (ixabiso) zombini zenziwe ngohlobo olufanayo kuzo zonke izikhangeli. Njengoko kuphela i-IE kunye neFirefox exhasa "ukugcwalisa" umkhondo wabo ukusuka ekhohlo okanye ekunene kubhontsi njengendlela yokubonisa inkqubela phambili, asiyixhasi okwangoku.

Uluhlu lwemizekelo

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

Uluhlu lwezimvo lunamaxabiso afihlakeleyo minkunye max- 0kunye 100, ngokulandelelanayo. Ungakhankanya amaxabiso amatsha kwabo basebenzisa i minkunye maxneempawu.

Uluhlu lwemizekelo

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

Ngokungagqibekanga, amagalelo oluhlu "snap" ukuya kumaxabiso apheleleyo. Ukutshintsha oku, ungakhankanya stepixabiso. Kulo mzekelo ungezantsi, siphinda kabini inani lamanyathelo ngokusebenzisa step="0.5".

Isikhangeli sefayile

Igalelo lefayile lolona luhlu lunzima kwaye lufuna iJavaScript eyongezelelweyo ukuba ungathanda ukuzidibanisa nomsebenzi Khetha ifayile... kwaye ukhethiweyo wegama lefayile elibhaliweyo.

Khetha ifayile

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFile">
  <label class="custom-file-label" for="customFile">Choose file</label>
</div>

Sifihla ifayile engagqibekanga <input>sisebenzisa opacitykwaye endaweni yoko isitayile i <label>. Iqhosha liyenziwa kwaye libekwe nge ::after. Okokugqibela, sibhengeza u-a widthkunye heightnakwisithuba <input>esifanelekileyo somxholo ongqongileyo.

Ukuguqulela okanye ukulungisa imitya

I :lang()-pseudo-class isetyenziselwa ukuvumela uguqulelo lombhalo "Khangela" kwezinye iilwimi. Khipha ngaphezulu okanye yongeza amangeniso $custom-file-textkuguqulo lweSass ngethegi yolwimi olufanelekileyo kunye neentambo zasekuhlaleni. Iintambo zesiNgesi zinokulungiswa ngendlela efanayo. Umzekelo, nantsi indlela umntu anokongeza ngayo inguqulelo yeSpanish (ikhowudi yolwimi lwesiSpanish ithi es):

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

Nantsi lang(es)intshukumo kwigalelo lefayile yesiko loguqulelo lwesiSpanish:

Seleccionar Archivo

<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>

Kuya kufuneka usete ulwimi loxwebhu lwakho (okanye umthi ongezantsi walo) ngokuchanekileyo ukuze okubhaliweyo okuchanekileyo kuboniswe. Oku kunokwenziwa kusetyenziswa uphawu loyelelwano langlwento<html> okanye Content-Languageisihloko seHTTP , phakathi kwezinye iindlela.
