ʻOiai e hoʻohana ʻo Bootstrap i kēia mau ʻano ma nā mākaʻikaʻi āpau, ʻaʻole kākoʻo piha ʻo Internet Explorer 11 a ma lalo i ke disabledʻano ma kahi <fieldset>. E hoʻohana i ka JavaScript maʻamau no ka hoʻopau ʻana i ke kahua kahua ma kēia mau polokalamu kele pūnaewele.

Hāʻawi i nā manaʻo manaʻo koʻikoʻi a hiki ke hana ʻia i kāu mea hoʻohana me ka hōʻoia ʻana o ka palapala HTML5– i loaʻa i kā mākou mau polokalamu kele pūnaewele āpau . E koho mai i ka manaʻo manaʻo hōʻoia paʻamau o ka polokalamu kele pūnaewele, a i ʻole e hoʻokō i nā memo maʻamau me kā mākou papa i kūkulu ʻia a me ka JavaScript hoʻomaka.

Manaʻo mākou i kēia manawa e hoʻohana i nā ʻano hōʻoia maʻamau, no ka mea, ʻaʻole ʻike mau ʻia nā memo hōʻoia paʻamau o ka polokalamu kele pūnaewele i nā ʻenehana kōkua i nā polokalamu kele a pau (ʻoi loa, ʻo Chrome ma ka papapihi a me ka mobile).

Pehea e hana ai

Eia ke ʻano o ka hana ʻana o ka palapala hōʻoia me Bootstrap:

  • Hoʻohana ʻia ka hōʻoia palapala HTML ma o nā papa pseudo ʻelua o CSS, :invalida me :valid. Pili ia i <input>, <select>, a me na <textarea>mea.
  • Hoʻopili ʻo Bootstrap i nā ʻano :invalida me :validnā ʻano i ka papa makua .was-validated, i hoʻohana pinepine ʻia i ka <form>. A i ʻole, hōʻike ʻia kekahi kahua i koi ʻia me ka waiwai ʻole ma ka hoʻouka ʻana i ka ʻaoʻao. Ma kēia ala, hiki iā ʻoe ke koho i ka wā e hoʻāla ai iā lākou (maʻamau ma hope o ka hoʻāʻo ʻia ʻana o ka palapala).
  • No ka hoʻihoʻi hou ʻana i ke ʻano o ke ʻano (no ka laʻana, ma ke ʻano o ka hoʻouna ʻana i nā palapala hoʻoikaika me ka hoʻohana ʻana iā AJAX), e wehe i ka .was-validatedpapa mai ka papa <form>ma hope o ka waiho ʻana.
  • Ma ke ʻano he hāʻule, .is-invalida .is-validhiki ke hoʻohana ʻia nā papa ma kahi o nā pseudo-papa no ka hōʻoia ʻaoʻao o ka server . ʻAʻole lākou makemake i kahi .was-validatedpapa makua.
  • Ma muli o ke kaohi ʻana i ka hana ʻana o CSS, ʻaʻole hiki iā mākou (i kēia manawa) ke hoʻopili i nā kaila i kahi <label>e hiki mai ana ma mua o ka mana o ka puka ma ka DOM me ke kōkua ʻole o ka JavaScript maʻamau.
  • Kākoʻo nā mākaʻikaʻi hou a pau i ka API hoʻopaʻa paʻa , he pūʻulu o nā ala JavaScript no ka hōʻoia ʻana i nā mana palapala.
  • Hiki i nā memo manaʻo ke hoʻohana i nā mea paʻa o ka polokalamu kele pūnaewele (ʻokoʻa no kēlā me kēia polokalamu kele pūnaewele, a hiki ʻole ke hoʻopaʻa ʻia ma o CSS) a i ʻole kā mākou ʻano manaʻo manaʻo maʻamau me HTML a me CSS hou.
  • Hiki iā ʻoe ke hāʻawi i nā memo kūpono maʻamau me setCustomValidityka JavaScript.

Me ka noʻonoʻo, e noʻonoʻo i nā demos aʻe no kā mākou ʻano hōʻoia hōʻoia maʻamau, nā papa ʻaoʻao kikowaena koho, a me nā mea hoʻokele paʻa.

Nā ʻano maʻamau

No nā memo hōʻoia puka Bootstrap maʻamau, pono ʻoe e hoʻohui i ke novalidateʻano boolean i kāu <form>. Hoʻopau kēia i nā ʻōlelo aʻoaʻo manaʻo paʻamau o ka polokalamu kele pūnaewele, akā hāʻawi mau i ke komo i nā API hōʻoia palapala ma JavaScript. E ho'āʻo e waiho i ka palapala ma lalo nei; kā mākou JavaScript e hoʻopau i ke pihi hoʻouna a hoʻouna i nā manaʻo iā ʻoe.

Ke ho'āʻo nei e hoʻouna, e ʻike ʻoe i nā ʻano :invalida me :validnā ʻano i hoʻopili ʻia i kāu kaohi puka.

Nā palapala maʻamau

No ka hoʻopilikino hou aʻe a me ka paʻa ʻana o ka polokalamu kele pūnaewele, e hoʻohana i kā mākou mau ʻano hana maʻamau e hoʻololi i nā mea paʻa. Kūkulu ʻia lākou ma luna o ka markup semantic a hiki ke loaʻa, no laila he mau pani paʻa no kēlā me kēia mana paʻamau.

Nā pahu pahu a me nā lekiō

Hoʻopili ʻia kēlā me kēia pahu pahu a me ka lekiō <div>me kahi kaikunāne <span>e hana i kā mākou mana maʻamau a <label>no ka kikokikona e pili pū ana. Ma ka hoʻolālā, ua like kēia me kā mākou paʻamau .form-check.

Hoʻohana mākou i ka mea koho kaikunāne ( ~) no kā mākou <input>mokuʻāina a pau—e like me :checked—e hana pono i kā mākou hōʻailona puka maʻamau. Ke hui pū ʻia me ka .custom-control-labelpapa, hiki iā mākou ke hana i ka kikokikona no kēlā me kēia mea e pili ana i ke kūlana o ka <input>'āina.

Hūnā mākou i ka paʻamau <input>me opacityka hoʻohana ʻana i ke .custom-control-labelkūkulu ʻana i kahi hōʻailona maʻamau maʻamau ma kona wahi me ::beforea ::after. ʻO ka mea pōʻino, ʻaʻole hiki iā mākou ke kūkulu i kahi mea maʻamau mai ka mea wale nō no ka mea ʻaʻole hana ka <input>CSS ma ia mea.content

Ma nā mokuʻāina i nānā ʻia, hoʻohana mākou i nā kiʻi SVG i hoʻokomo ʻia base64 mai Open Iconic . Hāʻawi kēia iā mākou i ka mana maikaʻi loa no ke kālai ʻana a me ka hoʻonohonoho ʻana ma waena o nā polokalamu kele pūnaewele a me nā polokalamu.

Nā pahu koho

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheck1">
  <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
</div>

Hiki nō hoʻi i nā pahu hoʻopaʻa maʻamau ke hoʻohana i ka :indeterminatepapa pseudo ke hoʻonohonoho lima ʻia ma o JavaScript (ʻaʻohe ʻano HTML i loaʻa no ka wehewehe ʻana).

Inā ʻoe e hoʻohana ana i ka jQuery, pono e like me kēia:

$('.your-checkbox').prop('indeterminate', true)

Lekiō

<div class="custom-control custom-radio">
  <input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio1">Toggle this custom radio</label>

</div>

Kinohi

Hiki ke hoʻopaʻa ʻia nā pahu koho a me nā lekiō. E hoʻohui i ka disabledʻano boolean i ka <input>a me ka hōʻailona maʻamau a me ka wehewehe ʻana i ka lepili.

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheckDisabled" disabled>
  <label class="custom-control-label" for="customCheckDisabled">Check this custom checkbox</label>

<div class="custom-control custom-radio">

  <label class="custom-control-label" for="customRadioDisabled">Toggle this custom radio</label>
</div>

E koho i ka papa kuhikuhi

Pono nā menus <select>kuʻuna i kahi papa maʻamau, .custom-selecte hoʻoulu i nā ʻano maʻamau. Ua kaupalena ʻia nā ʻano hana maʻamau i ke ʻano <select>o ka mua a ʻaʻole hiki ke hoʻololi i ka <option>s ma muli o nā palena o ka polokalamu kele pūnaewele.

<select class="custom-select">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Hiki iā ʻoe ke koho mai nā koho maʻamau liʻiliʻi a nui e hoʻohālikelike i kā mākou mau kikokikona like ʻole.

<select class="custom-select custom-select-lg mb-3">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>

<select class="custom-select custom-select-sm">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>

Kākoʻo multipleʻia ka ʻano:

<select class="custom-select" multiple>
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>

E like me ke sizeʻano:

<select class="custom-select" size="3">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Laulā

E hana i nā <input type="range">mana maʻamau me .custom-range. ʻO ke mele (ke kua) a me ka manamana nui (ka waiwai) ua ʻano like ke ʻano ma waena o nā polokalamu kele pūnaewele. ʻOiai ʻo IE a me Firefox wale nō ke kākoʻo i ka "hoʻopiha" i kā lākou mele mai ka hema a i ʻole ka ʻākau o ka manamana nui i mea e ʻike maka ai i ka holomua, ʻaʻole mākou e kākoʻo i kēia manawa.

<label for="customRange1">Example range</label>
<input type="range" class="custom-range" id="customRange1">

Loaʻa i nā mea hoʻokomo laulā nā waiwai pili no mina max- 0a me 100, kēlā me kēia. Hiki iā ʻoe ke kuhikuhi i nā waiwai hou no ka poʻe e hoʻohana ana i ka mina me maxnā ʻano.

<label for="customRange2">Example range</label>
<input type="range" class="custom-range" min="0" max="5" id="customRange2">

ʻO ka mea paʻamau, ʻo nā mea hoʻokomo i ka "snap" i nā waiwai integer. No ka hoʻololi i kēia, hiki iā ʻoe ke kuhikuhi i kahi stepwaiwai. Ma ka laʻana ma lalo nei, pāpālua mākou i ka helu o nā ʻanuʻu ma ka hoʻohana ʻana i step="0.5".

<label for="customRange3">Example range</label>
<input type="range" class="custom-range" min="0" max="5" step="0.5" id="customRange3">

Pūnaewele waihona

ʻO ka hoʻokomo faila ka mea ʻoi loa o ka puʻupuʻu a koi aku i ka JavaScript hou inā makemake ʻoe e hoʻopili iā lākou me ka koho koho faila… a me nā kikokikona inoa faila i koho ʻia.

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFile">
  <label class="custom-file-label" for="customFile">Choose file</label>
</div>

Hūnā mākou i ka faila paʻamau <input>ma o opacityke kāʻili ʻana i ka <label>. Hana ʻia ka pihi a hoʻonoho ʻia me ::after. ʻO ka hope, ke haʻi aku nei mākou i ka widtha heightma ka <input>no ka hoʻokaʻawale kūpono no nā ʻike a puni.

Unuhi a hoʻopololei paha i nā kaula

Hoʻohana ʻia ka :lang()pseudo-class no ka unuhi ʻana o ka kikokikona "Browse" i nā ʻōlelo ʻē aʻe. Hoʻopau a hoʻohui i nā mea hoʻokomo i ka $custom-file-texthoʻololi Sass me ka hōʻailona ʻōlelo kūpono a me nā kaula kūloko. Hiki ke hoʻopilikino ʻia nā kaula English i ke ʻano like. Eia kekahi laʻana, pehea e hoʻohui ai kekahi i ka unuhi Paniolo (ʻo ke code ʻōlelo Paniolo es):

$custom-file-text: (
  en: "Browse",
  es: "Elegir"
);

Eia ka lang(es)hana ma ka waihona waihona maʻamau no ka unuhi Paniolo:

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFileLang" lang="es">
  <label class="custom-file-label" for="customFileLang">Seleccionar Archivo</label>
</div>

Pono ʻoe e hoʻonohonoho pololei i ka ʻōlelo o kāu palapala (a i ʻole ka lāʻau lalo) i mea e hōʻike ʻia ai ke kikokikona pololei. Hiki ke hana i kēia me ka hoʻohana ʻana i ke langʻano ma ka <html>element a i ʻole ke Content-Languagepoʻomanaʻo HTTP , ma waena o nā ʻano hana ʻē aʻe.
