Kontroles en radio's
Meitsje konsekwinte karfakjes en radio's foar cross-browser en cross-apparaten mei ús folslein herskreaune kontrôlekomponint.
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 id
en for
attributen om te relatearjen de <input>
en <label>
. Wy brûke de sibling-selektor ( ~
) foar al ús <input>
steaten, lykas :checked
of :disabled
. As kombinearre mei de .form-check-label
klasse, 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 :indeterminate
pseudo-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 disabled
attribút 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="flexCheckIndeterminateDisabled" disabled>
<label class="form-check-label" for="flexCheckIndeterminateDisabled">
Disabled indeterminate checkbox
</label>

<label class="form-check-label" for="flexRadioDefault1">

</label>
</div>
Switches
In switch hat de markup fan in oanpast karfakje, mar brûkt de .form-switch
klasse om in toggle switch te werjaan. Beskôgje gebrûk role="switch"
om de aard fan 'e kontrôle krekter oer te bringen oan assistinte technologyen dy't dizze rol stypje. Yn âldere assistive technologyen sil it gewoan wurde oankundige as in reguliere karfakje as in fallback. Switches stypje ek it disabled
attribút.
<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="flexSwitchCheckDisabled">Disabled switch checkbox input</label>
</div>
<div class="form-check form-switch">
<input class="form-check-input" type="checkbox" role="switch" 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-inline
oan 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>
Reverse
Set jo karfakjes, radio's en skeakels op 'e tsjinoerstelde kant mei de .form-check-reverse
modifier-klasse.
<div class="form-check form-check-reverse">
<input class="form-check-input" type="checkbox" value="" id="reverseCheck1">
<label class="form-check-label" for="reverseCheck1">
Reverse checkbox
</label>
</div>
<div class="form-check form-check-reverse">
<input class="form-check-input" type="checkbox" value="" id="reverseCheck2" disabled>
<label class="form-check-label" for="reverseCheck2">
Disabled reverse checkbox
</label>
</div>
<div class="form-check form-switch form-check-reverse">
<input class="form-check-input" type="checkbox" id="flexSwitchCheckReverse">
<label class="form-check-label" for="flexSwitchCheckReverse">Reverse switch checkbox input</label>
</div>
Sûnder labels
Ferwiderje de omslach .form-check
foar 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 .btn
stilen te brûken ynstee fan .form-check-label
op '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>
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>
