Fuq din il-paġna

Approċċ

Il-kaxxi ta' kontroll u r-radjijiet default tal-browser huma sostitwiti bl-għajnuna ta' .form-check, serje ta' klassijiet għaż-żewġ tipi ta' input li jtejbu t-tqassim u l-imġieba tal-elementi HTML tagħhom, li jipprovdu customization akbar u konsistenza cross browser. Il-kaxxi ta' kontroll huma biex tagħżel għażla waħda jew diversi f'lista, filwaqt li r-radjijiet huma biex tagħżel għażla waħda minn ħafna.

Strutturalment, <input>s u s tagħna <label>huma elementi aħwa għall-kuntrarju ta ' <input>fi ħdan a <label>. Dan huwa kemmxejn aktar verbose peress li trid tispeċifika idu forattributi biex tirrelata l- <input>u <label>. Aħna nużaw is-selettur tal-aħwa ( ~) għall- <input>istati kollha tagħna, bħal :checkedjew :disabled. Meta kkombinati mal- .form-check-labelklassi, nistgħu faċilment stil tat-test għal kull oġġett ibbażat fuq l- <input>istat ta '.

Il-kontrolli tagħna jużaw ikoni Bootstrap personalizzati biex jindikaw stati ċċekkjati jew indeterminati.

Kontrolli

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="flexCheckDefault">
  <label class="form-check-label" for="flexCheckDefault">
    Default checkbox
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="flexCheckChecked" checked>
  <label class="form-check-label" for="flexCheckChecked">
    Checked checkbox
  </label>
</div>

Indeterminat

Checkboxes jistgħu jutilizzaw il- :indeterminatepsewdo klassi meta ssettjati manwalment permezz ta' JavaScript (m'hemm l-ebda attribut HTML disponibbli biex jiġi speċifikat).

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="flexCheckIndeterminate">
  <label class="form-check-label" for="flexCheckIndeterminate">
    Indeterminate checkbox
  </label>
</div>

B'diżabilità

Żid l- disabledattribut u l- <label>i assoċjati huma awtomatikament stilati biex jaqblu ma 'kulur eħfef biex jgħinu jindikaw l-istat tal-input.

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="flexCheckDisabled" disabled>
  <label class="form-check-label" for="flexCheckDisabled">
    Disabled checkbox
  </label>
</div>
<div class="form-check">

Swiċċijiet

Swiċċ għandu l-markup ta' kaxxa ta' kontroll tad-dwana iżda juża l- .form-switchklassi biex jagħmel toggle switch. Ikkunsidra li tuża role="switch"biex twassal b'mod aktar preċiż in-natura tal-kontroll għal teknoloġiji ta 'assistenza li jappoġġaw dan ir-rwol. F'teknoloġiji ta' assistenza eqdem, se sempliċiment titħabbar bħala kaxxa ta' kontroll regolari bħala riżerva. Swiċċijiet jappoġġjaw ukoll l- disabledattribut.

<div class="form-check form-switch">
  <input class="form-check-input" type="checkbox" role="switch" id="flexSwitchCheckDefault">
  <label class="form-check-label" for="flexSwitchCheckDefault">Default switch checkbox input</label>
</div>
<div class="form-check form-switch">
  <input class="form-check-input" type="checkbox" role="switch" id="flexSwitchCheckChecked" checked>
  <label class="form-check-label" for="flexSwitchCheckChecked">Checked switch checkbox input</label>
</div>
<div class="form-check form-switch">
  <input class="form-check-input" type="checkbox" role="switch" id="flexSwitchCheckDisabled" disabled>

  <label class="form-check-label" for="flexSwitchCheckCheckedDisabled">Disabled checked switch checkbox input</label>
</div>

Default (munzelli)

B'mod awtomatiku, kwalunkwe numru ta' kaxxi ta' kontroll u radjijiet li huma aħwa immedjati se jkunu f'munzelli vertikalment u spazjati b'mod xieraq bi .form-check.

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="defaultCheck1">
  <label class="form-check-label" for="defaultCheck1">
    Default checkbox
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled>
  <label class="form-check-label" for="defaultCheck2">
    Disabled checkbox
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked>
  <label class="form-check-label" for="exampleRadios1">
    Default radio
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2">
  <label class="form-check-label" for="exampleRadios2">
    Second default radio
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled>
  <label class="form-check-label" for="exampleRadios3">
    Disabled radio
  </label>
</div>

F'konformità

Aggruppa kaxxi ta' kontroll jew radjijiet fuq l-istess ringiela orizzontali billi żżid .form-check-inlinema' kwalunkwe .form-check.

<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1">
  <label class="form-check-label" for="inlineCheckbox1">1</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2">
  <label class="form-check-label" for="inlineCheckbox2">2</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled>
  <label class="form-check-label" for="inlineCheckbox3">3 (disabled)</label>
</div>
<div class="form-check form-check-inline">

  <label class="form-check-label" for="inlineRadio1">1</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">

  <label class="form-check-label" for="inlineRadio3">3 (disabled)</label>
</div>

Mingħajr tikketti

Ħalli barra t-tgeżwir .form-checkgħal checkboxes u radjijiet li m'għandhom l-ebda test tat-tikketta. Ftakar li xorta tipprovdi xi forma ta' isem aċċessibbli għal teknoloġiji ta' assistenza (per eżempju, billi tuża aria-label). Ara t- taqsima tal- aċċessibbiltà tal-ħarsa ġenerali tal-formoli għad-dettalji.

<div>
  <input class="form-check-input" type="checkbox" id="checkboxNoLabel" value="" aria-label="...">
</div>

<div>
  <input class="form-check-input" type="radio" name="radioNoLabel" id="radioNoLabel1" value="" aria-label="...">

Toggle buttuni

Oħloq kaxxi ta 'kontroll u buttuni tar-radju bħal buttuna billi tuża .btnstili aktar milli .form-check-labelfuq l- <label>elementi. Dawn il-buttuni toggle jistgħu jiġu miġbura aktar fi grupp ta ' buttuni jekk meħtieġ.

Buttuni ta' toggle tal-kaxxa ta' kontroll

<input type="checkbox" class="btn-check" id="btn-check" autocomplete="off">
<label class="btn btn-primary" for="btn-check">Single toggle</label>
<input type="checkbox" class="btn-check" id="btn-check-2" checked autocomplete="off">
<label class="btn btn-primary" for="btn-check-2">Checked</label>
<input type="checkbox" class="btn-check" id="btn-check-3" autocomplete="off" disabled>
<label class="btn btn-primary" for="btn-check-3">Disabled</label>
Viżwalment, dawn il-buttuni tat-toggle checkbox huma identiċi għall- buttuni tal-toggle tal-plugin tal-buttuna . Madankollu, huma mibgħuta b'mod differenti minn teknoloġiji ta' assistenza: it-toggles tal-kaxxa tal-kontroll se jitħabbru mill-qarrejja tal-iskrin bħala "iċċekkjati"/"mhux iċċekkjati" (peress li, minkejja d-dehra tagħhom, huma fundamentalment għadhom kaxxi ta' kontroll), filwaqt li l-buttuni tat-toggle tal-plugin tal-buttuna se jkunu. imħabbra bħala "buttuna"/"buttuna magħfusa". L-għażla bejn dawn iż-żewġ approċċi tiddependi fuq it-tip ta 'toggle li qed toħloq, u jekk it-toggle jagħmilx sens jew le għall-utenti meta mħabbar bħala checkbox jew bħala buttuna attwali.

Buttuni ta' toggle tar-radju

<input type="radio" class="btn-check" name="options" id="option1" autocomplete="off" checked>
<label class="btn btn-secondary" for="option1">Checked</label>

<input type="radio" class="btn-check" name="options" id="option2" autocomplete="off">
