Checks og radioer
Skab ensartede kryds-browsere og på tværs af enheder afkrydsningsfelter og radioer med vores fuldstændigt omskrevne kontrolkomponent.
Nærme sig
Browserens standardafkrydsningsfelter og radioer erstattes ved hjælp af .form-check
, en række klasser for begge inputtyper, der forbedrer layoutet og adfærden af deres HTML-elementer, som giver større tilpasning og ensartethed på tværs af browsere. Afkrydsningsfelter er til at vælge en eller flere muligheder på en liste, mens radioer er til at vælge en mulighed blandt mange.
Strukturelt er vores <input>
s og <label>
s søskendeelementer i modsætning til et <input>
inden for et <label>
. Dette er lidt mere udførligt, da du skal specificere id
og for
attributter for at relatere <input>
og <label>
. Vi bruger søskendevælgeren ( ~
) til alle vores <input>
stater, f.eks . :checked
eller :disabled
. Når det kombineres med .form-check-label
klassen, kan vi nemt style teksten for hvert element baseret på <input>
's-tilstanden.
Vores checks bruger tilpassede Bootstrap-ikoner til at angive kontrollerede eller ubestemte tilstande.
Checks
<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>
Ubestemt
Afkrydsningsfelter kan bruge :indeterminate
pseudoklassen, når de indstilles manuelt via JavaScript (der er ingen tilgængelig HTML-attribut til at angive den).
<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>
handicappet
Tilføj disabled
attributten, og de tilknyttede <label>
s bliver automatisk stylet til at matche med en lysere farve for at hjælpe med at angive inputts tilstand.
<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>
Radioer
<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>
handicappet
Tilføj disabled
attributten, og de tilknyttede <label>
s bliver automatisk stylet til at matche med en lysere farve for at hjælpe med at angive inputts tilstand.
<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>
Afbrydere
En switch har markeringen af et brugerdefineret afkrydsningsfelt, men bruger .form-switch
klassen til at gengive en skiftekontakt. Switche understøtter også disabled
attributten.
<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>
Standard (stablet)
Som standard vil et hvilket som helst antal afkrydsningsfelter og radioer, der er umiddelbare søskende, være lodret stablet og passende fordelt med .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>
Inline
Grupper afkrydsningsfelter eller radioer i den samme vandrette række ved at tilføje .form-check-inline
til en hvilken som helst .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>
Uden etiketter
Udelad indpakningen .form-check
for afkrydsningsfelter og radioer, der ikke har nogen etikettekst. Husk stadig at give en form for tilgængeligt navn til hjælpeteknologier (f.eks. ved hjælp af aria-label
). Se afsnittet om formularoversigts tilgængelighed for detaljer.
<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>
Skift knapper
Opret knaplignende afkrydsningsfelter og alternativknapper ved at bruge .btn
typografier i stedet for .form-check-label
på <label>
elementerne. Disse skifteknapper kan yderligere grupperes i en knapgruppe, hvis det er nødvendigt.
Afkrydsningsfelt til/fra-knapper
<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>
Radioskift-knapper
<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>
Skitserede stilarter
Forskellige varianter af .btn
, såsom ved de forskellige skitserede stilarter, understøttes.
<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>
