fankatoavana
Manome valiny sarobidy sy azo atao ho an'ny mpampiasa anao miaraka amin'ny fanamarinana ny endrika HTML5, amin'ny alàlan'ny fitondran-tena mahazatra amin'ny navigateur na fomba fanao mahazatra sy JavaScript.
Amin'ity pejy ity
Fantatsika fa amin'izao fotoana izao dia tsy azo idirana ny fomba fanamarinana manokana momba ny mpanjifa sy ny toro-hevitra momba ny fitaovana, satria tsy mihatra amin'ny teknolojia manampy izy ireo. Raha miasa amin'ny vahaolana izahay, dia manoro hevitra izahay na mampiasa ny safidy amin'ny lafiny server na ny fomba fanamarinana ny navigateur default.
Ahoana ny fiasan'izany
Toy izao ny fomba fiasan'ny validation amin'ny Bootstrap:
- Ny fanamarinana endrika HTML dia ampiharina amin'ny alàlan'ny pseudo-class roa an'ny CSS,
:invalidary:valid. Mihatra amin'ny<input>,<select>, ary<textarea>singa izany. - Ny Bootstrap dia mametaka ny
:invalidsy ny:validfomba ho an'ny.was-validatedkilasin'ny ray aman-dreny, matetika ampiharina amin'ny<form>. Raha tsy izany, izay saha ilaina tsy misy sandany dia miseho ho tsy manan-kery amin'ny entana pejy. Amin'izany fomba izany, azonao atao ny misafidy hoe rahoviana no hampavitrika azy ireo (matetika rehefa avy nanandrana ny fandefasana taratasy). - Mba hamerenana ny endriky ny endrika (ohatra, amin'ny fandefasana endrika mavitrika amin'ny fampiasana AJAX), esory ny
.was-validatedkilasy<form>indray aorian'ny fandefasana. - Amin'ny maha-famerenana azy,
.is-invalidary ny.is-validkilasy dia azo ampiasaina ho solon'ny kilasy pseudo ho an'ny fanamarinana amin'ny lafiny mpizara . Tsy mila.was-validatedkilasy ray aman-dreny izy ireo. - Noho ny faneriterena amin'ny fomba fiasan'ny CSS dia tsy afaka (amin'izao fotoana izao) izahay hampihatra fomba amin'ny endrika iray
<label>alohan'ny fifehezana endrika ao amin'ny DOM raha tsy misy ny fanampian'ny JavaScript mahazatra. - Ny navigateur maoderina rehetra dia manohana ny API validation constraint , andiana fomba JavaScript hanamarinana ny fanaraha-maso ny endrika.
- Ny hafatra valin- kafatra dia mety hampiasa ny default amin'ny navigateur (samy hafa ho an'ny navigateur tsirairay, ary tsy azo fehezina amin'ny alàlan'ny CSS) na ny fomba fanehoan-kevitra mahazatra misy HTML sy CSS fanampiny.
- Azonao atao ny manome hafatra manan-kery manokana
setCustomValidityamin'ny JavaScript.
Miaraka amin'izany ao an-tsaina, diniho ireto demo manaraka ireto ho an'ny fomba fanamarinana ny endrika fanaontsika, ny kilasin'ny mpizara safidy, ary ny tsy mety amin'ny navigateur.
Fomba mahazatra
Ho an'ny hafatra fanamarinana ny endrika Bootstrap mahazatra dia mila manampy ny novalidatetoetra boolean amin'ny <form>. Izany dia manafoana ny toro-hevitra momba ny valin-kafatra ho an'ny navigateur, fa mbola manome fidirana amin'ny API fanamarinana endrika amin'ny JavaScript. Andramo ny mandefa ny taratasy eto ambany; ny JavaScript dia hanakana ny bokotra fandefasana ary hampita hevitra aminao. Rehefa manandrana manatitra ianao dia ho hitanao ny fomba :invalidsy ny :validfomba ampiharina amin'ny fanaraha-maso ny endrikao.
Mampihatra loko, sisin-tany, fomba fifantohana, ary kisary ambadika mba hampitana hevitra tsara kokoa ny fomba fanehoan-kevitra manokana. Ny kisary background ho an'ny <select>s dia tsy misy afa-tsy amin'ny .form-select, fa tsy .form-control.

Tsy liana amin'ny hafatra fanehoan-kevitra momba ny fanamarinana manokana na manoratra JavaScript hanovana fitondran-tena? Tsara daholo, azonao ampiasaina ny default navigateur. Andramo mandefa ny taratasy etsy ambany. Miankina amin'ny navigateur sy ny OS, dia hahita fomba fanehoan-kevitra hafa kely ianao.
Na dia tsy azo atao amin'ny CSS aza ireo fomba fanehoan-kevitra ireo, dia mbola azonao atao ny manamboatra ny lahatsoratra fanehoan-kevitra amin'ny alàlan'ny JavaScript.

Manoro hevitra izahay hampiasa ny fanamarinana amin'ny lafiny mpanjifa, fa raha toa ka mila fanamarinana amin'ny lafiny server ianao, dia azonao atao ny manondro saha misy endrika tsy mety sy manankery miaraka amin'ny .is-invalidsy .is-valid. Mariho fa .invalid-feedbacktohana ihany koa amin'ireo kilasy ireo.
Ho an'ny saha tsy mety, ataovy azo antoka fa mifandray amin'ny sahan'ny endrika mifanaraka amin'izany ny hafatra tsy mety/diso aria-describedby(marihina fa ity toetra ity dia mamela mihoatra ny iray idazo resahana, raha toa ka efa manondro lahatsoratra amin'ny endrika fanampiny ny saha).
Mba hamahana ny olana amin'ny sisintany radii , mila kilasy fanampiny ny vondrona fampidirana .has-validation.

Sarintany
Ity ny sarintany Sass fanamarinana avy amin'ny _variables.scss. Amboary na hanitarana izany mba hamoronana fanjakana hafa na fanampiny.
$form-validation-states: (
"valid": (
"color": $form-feedback-valid-color,
"icon": $form-feedback-icon-valid
),
"invalid": (
"color": $form-feedback-invalid-color,
"icon": $form-feedback-icon-invalid
)
);
Ny sarintanin'ny $form-validation-statesdia mety ahitana mason-tsivana telo azo atao hanilihana ny toro-hevitra sy ny fomba fifantohana.
manome fitoerana
Ampiasaina hamerenana ny $form-validation-statessandan'ny sari-tany mba hamoronana fomba fanamarinanay. Ny fanovana rehetra amin'ny sarintany Sass etsy ambony dia ho hita ao amin'ny CSS natambatrao amin'ny alalan'ity loop ity.
@each $state, $data in $form-validation-states {
@include form-validation-state($state, $data...);
}
Customizing
Ny fanjakana fanamarinana dia azo amboarina amin'ny alàlan'ny Sass miaraka amin'ny $form-validation-statessarintany. Ao amin'ny _variables.scssrakitray, ity sari-tany Sass ity dia ny fomba hamoronana ny fanjakana default valid/ invalidfanamarinana. Ao anatin'izany ny sarintany misy akany ho an'ny fanamboarana ny lokon'ny fanjakana tsirairay, ny kisary, ny lokon'ny fitaovana, ary ny aloky ny fifantohana. Na dia tsy misy fanjakana hafa tohanan'ny mpitety tranonkala aza, ireo mampiasa fomba fanao mahazatra dia afaka manampy mora foana ny fanehoan-kevitra sarotra kokoa.
Azafady, azafady fa tsy manoro hevitra ny manamboatra $form-validation-statessoatoavina izahay raha tsy manova ny form-validation-statemixin koa .
