Vormkontroles

Gee teksvormkontroles soos <input>s en <textarea>s 'n opgradering met pasgemaakte style, grootte, fokustoestande en meer.

Voorbeeld

html 
<div class="mb-3">
  <label for="exampleFormControlInput1" class="form-label">Email address</label>
  <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="[email protected]">
</div>
<div class="mb-3">
  <label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
  <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>

Grootte

Stel hoogtes deur klasse soos .form-control-lgen .form-control-sm.

html 
<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg" aria-label=".form-control-lg example">
<input class="form-control" type="text" placeholder="Default input" aria-label="default input example">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm" aria-label=".form-control-sm example">

Gestrem

Voeg die disabledBoolese kenmerk by 'n invoer om dit 'n grys voorkoms te gee, wysergebeurtenisse te verwyder en fokus te voorkom.

html 
<input class="form-control" type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled>
<input class="form-control" type="text" value="Disabled readonly input" aria-label="Disabled input example" disabled readonly>

Leesalleen

Voeg die readonlyBoole-kenmerk by 'n invoer om verandering van die invoer se waarde te voorkom. readonlyinsette kan steeds gefokus en gekies word, terwyl disabledinsette nie kan nie.

html 
<input class="form-control" type="text" value="Readonly input here..." aria-label="readonly input example" readonly>

Leesalleen gewone teks

As jy <input readonly>elemente in jou vorm as gewone teks wil hê, vervang .form-controlmet .form-control-plaintextom die verstek vormveldstilering te verwyder en die korrekte marginen te behou padding.

html 
  <div class="mb-3 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="mb-3 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">
    </div>
  </div>
html 
<form class="row g-3">
  <div class="col-auto">
    <label for="staticEmail2" class="visually-hidden">Email</label>

Kleur

Stel die type="color"en voeg .form-control-colorby die <input>. Ons gebruik die wysigerklas om vaste heights te stel en sommige teenstrydighede tussen blaaiers te ignoreer.

html 
<label for="exampleColorInput" class="form-label">Color picker</label>
<input type="color" class="form-control form-control-color" id="exampleColorInput" value="#563d7c" title="Choose your color">

Datalyste

Datalyste laat jou toe om 'n groep <option>s te skep wat verkry kan word (en outovoltooi) van binne 'n <input>. Dit is soortgelyk aan <select>elemente, maar kom met meer spyskaartstileringsbeperkings en verskille. Terwyl die meeste blaaiers en bedryfstelsels 'n mate van ondersteuning vir <datalist>elemente insluit, is hul stilering op sy beste inkonsekwent.

Kom meer te wete oor ondersteuning vir datalyselemente .

html 
<label for="exampleDataList" class="form-label">Datalist example</label>
<input class="form-control" list="datalistOptions" id="exampleDataList" placeholder="Type to search...">
<datalist id="datalistOptions">
  <option value="San Francisco">
  <option value="New York">
  <option value="Seattle">
  <option value="Los Angeles">
  <option value="Chicago">
</datalist>
