Kontroles en radio's

Meitsje konsekwinte karfakjes en radio's foar cross-browser en cross-apparaten mei ús folslein herskreaune kontrôlekomponint.

Op dizze side

Oanpak

Browser standert karfakjes en radios wurde ferfongen mei help fan .form-check, in rige fan klassen foar beide ynfier typen dy't ferbettert de yndieling en gedrach fan harren HTML eleminten, dat soarget foar grutter maatwurk en cross blêder konsistinsje. Checkboxes binne foar it selektearjen fan ien of meardere opsjes yn in list, wylst radio's binne foar it selektearjen fan ien opsje út in protte.

Struktureel binne ús <input>s en <label>s sibling-eleminten yn tsjinstelling ta in <input>binnen in <label>. Dit is wat mear verbose as jo moatte opjaan iden forattributen om te relatearjen de <input>en <label>. Wy brûke de sibling-selektor ( ~) foar al ús <input>steaten, lykas :checkedof :disabled. As kombinearre mei de .form-check-labelklasse, kinne wy ​​​​de tekst foar elk item maklik stylearje op basis fan <input>'e steat.

Us kontrôles brûke oanpaste Bootstrap-ikoanen om kontrolearre of ûnbepaalde steaten oan te jaan.

Sjeks

<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>

Unbepaald

Checkboxes kinne de :indeterminatepseudo-klasse brûke as se mei de hân ynsteld wurde fia JavaScript (d'r is gjin HTML-attribút beskikber om it oan te jaan).

<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>

Ynvalide

Foegje it disabledattribút ta en de assosjearre <label>s wurde automatysk styled om te passen mei in lichtere kleur om te helpen de steat fan 'e ynfier oan te jaan.

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

Radios

<div class="form-check">
  <input class="form-check-input" type="radio" name="flexRadioDefault" id="flexRadioDefault1">
  <label class="form-check-label" for="flexRadioDefault1">
    Default radio
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="flexRadioDefault" id="flexRadioDefault2" checked>
  <label class="form-check-label" for="flexRadioDefault2">
    Default checked radio
  </label>
</div>

Ynvalide

Foegje it disabledattribút ta en de assosjearre <label>s wurde automatysk styled om te passen mei in lichtere kleur om te helpen de steat fan 'e ynfier oan te jaan.

<div class="form-check">
  <input class="form-check-input" type="radio" name="flexRadioDisabled" id="flexRadioDisabled" disabled>
  <label class="form-check-label" for="flexRadioDisabled">
    Disabled radio
  </label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="flexRadioDisabled" id="flexRadioCheckedDisabled" checked disabled>
  <label class="form-check-label" for="flexRadioCheckedDisabled">
    Disabled checked radio
  </label>
</div>

Switches

In switch hat de markup fan in oanpast karfakje, mar brûkt de .form-switchklasse om in toggle switch te werjaan. Switches stypje ek it disabledattribút.

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

Standert (steapele)

Standert sil elk oantal karfakjes en radio's dy't direkte sibling binne fertikaal steapele wurde en op passende ôfstân mei .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>

Ynline

Groepearje karfakjes as radio's op deselde horizontale rige troch ta te foegjen .form-check-inlineoan elke .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">
  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
  <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="inlineRadio2">2</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3" disabled>
  <label class="form-check-label" for="inlineRadio3">3 (disabled)</label>
</div>

Sûnder labels

Ferwiderje de omslach .form-checkfoar karfakjes en radio's dy't gjin labeltekst hawwe. Unthâld om noch in foarm fan tagonklike namme te jaan foar assistinte technologyen (bygelyks mei aria-label). Sjoch de seksje tagonklikens fan formulieren oersjoch foar details.

<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="...">
</div>

Skeakelje knoppen

Meitsje knop-like karfakjes en radioknoppen troch .btnstilen te brûken ynstee fan .form-check-labelop 'e <label>eleminten. Dizze wikselknoppen kinne as nedich wurde groepeare yn in knopgroep .

Knoppen foar karfakje wikselje

<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>
Visueel binne dizze karfakje-wikselknoppen identyk oan de knop-plugin-wikselknoppen . Se wurde lykwols oars oerbrocht troch assistinte technologyen: de karfakje-skeakels sille wurde oankundige troch skermlêzers as "kontrolearre" / "net kontrolearre" (omdat se, nettsjinsteande har uterlik, yn prinsipe noch karfakjes binne), wylst de knop-plugin-skeakelknoppen sille wêze oankundige as "knop" / "knop yndrukt". De kar tusken dizze twa oanpakken sil ôfhingje fan it type skeakel dat jo oanmeitsje, en oft de skeakel sin sil meitsje foar brûkers as se oankundige as in karfakje of as in feitlike knop.

Radio wikselje knoppen

<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">
<label class="btn btn-secondary" for="option2">Radio</label>

<input type="radio" class="btn-check" name="options" id="option3" autocomplete="off" disabled>
<label class="btn btn-secondary" for="option3">Disabled</label>

<input type="radio" class="btn-check" name="options" id="option4" autocomplete="off">
<label class="btn btn-secondary" for="option4">Radio</label>

Sketse stilen

Ferskillende farianten fan .btn, lykas by de ferskate sketste stilen, wurde stipe.



<input type="checkbox" class="btn-check" id="btn-check-outlined" autocomplete="off">
<label class="btn btn-outline-primary" for="btn-check-outlined">Single toggle</label><br>

<input type="checkbox" class="btn-check" id="btn-check-2-outlined" checked autocomplete="off">
<label class="btn btn-outline-secondary" for="btn-check-2-outlined">Checked</label><br>

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

<input type="radio" class="btn-check" name="options-outlined" id="danger-outlined" autocomplete="off">
<label class="btn btn-outline-danger" for="danger-outlined">Danger radio</label>
