Hōʻoia
Hāʻawi i nā manaʻo manaʻo koʻikoʻi a hiki ke hana ʻia i kāu mea hoʻohana me ka hōʻoia ʻana o ka palapala HTML5, ma o nā ʻano hana paʻamau o ka polokalamu kele pūnaewele a i ʻole nā ʻano kuʻuna a me JavaScript.
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,
:invalid
a me:valid
. Pili ia i<input>
,<select>
, a me<textarea>
nā mea. - Hoʻopili ʻo Bootstrap i nā ʻano
:invalid
a me:valid
nā ʻano i ka papa makua.was-validated
, i hoʻohana pinepine ʻia i ka<form>
. A i ʻole, ʻike ʻole 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-validated
papa mai ka papa<form>
ma hope o ka waiho ʻana. - Ma ke ʻano he hāʻule,
.is-invalid
a.is-valid
hiki ke hoʻohana ʻia nā papa ma kahi o nā pseudo-classes no ka hōʻoia ʻaoʻao server . ʻAʻole lākou makemake i kahi.was-validated
papa 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
setCustomValidity
ka JavaScript.
Me ka noʻonoʻo ʻana, e noʻonoʻo i nā demos aʻe no kā mākou ʻano hōʻoia ʻano maʻamau, nā papa ʻaoʻao kikowaena koho, a me nā paʻa ʻole o ka polokalamu kele pūnaewele.
Nā ʻano maʻamau
No nā memo hōʻoia puka Bootstrap maʻamau, pono ʻoe e hoʻohui i ke novalidate
ʻano 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 hāʻawi i nā manaʻo iā ʻoe. Ke ho'āʻo nei e hoʻouna, e ʻike ʻoe i nā ʻano :invalid
a me :valid
nā ʻano i hoʻopili ʻia i kāu kaohi puka.
Hoʻopili nā ʻano manaʻo manaʻo maʻamau i nā kala maʻamau, nā palena, nā ʻano kikoʻī, a me nā kiʻi ʻoniʻoni i hope e kamaʻilio maikaʻi i nā manaʻo. Loaʻa nā kiʻiona hope no <select>
