Balioztatzea
Eman iritzi baliotsu eta ekingarriak zure erabiltzaileei HTML5 inprimakiak baliozkotzearekin, arakatzailearen portaera lehenetsien edo estilo pertsonalizatuen eta JavaScripten bidez.
Nola dabil
Hona hemen inprimakien baliozkotzeak Bootstrap-ekin nola funtzionatzen duen:
- HTML inprimakiaren baliozkotzea CSSren bi sasi-klaseen bidez aplikatzen da,
:invalid
eta:valid
.<input>
,<select>
, eta<textarea>
elementuei aplikatzen zaie . - Bootstrap-ek
:invalid
eta:valid
estiloak.was-validated
klase nagusira ezartzen ditu, normalean<form>
. Bestela, baliorik gabeko derrigorrezko edozein eremu baliogabe gisa agertzen da orria kargatzean. Horrela, noiz aktibatu aukeratu dezakezu (normalean inprimakia bidaltzen saiatu ondoren). - Inprimakiaren itxura berrezartzeko (adibidez, AJAX erabiliz inprimaki dinamikoen bidalketa kasuan), kendu
.was-validated
klasea<form>
berriro bidali ondoren. - Errepide gisa,
.is-invalid
eta.is-valid
klaseak erabil daitezke zerbitzariaren baliozkotze sasi-klaseen ordez . Ez dute.was-validated
guraso klaserik behar. - CSS funtzionamenduaren mugak direla eta, ezin ditugu (gaur egun) estiloak aplikatu
<label>
DOM-en inprimaki-kontrol baten aurretik dagoen bati JavaScript pertsonalizatuaren laguntzarik gabe. - Arakatzaile moderno guztiek mugak baliozkotzeko APIa onartzen dute , inprimakien kontrolak balioztatzeko JavaScript metodo sorta bat.
- Iritzi-mezuek arakatzailearen lehenetsiak erabil ditzakete (desberdinak arakatzaile bakoitzeko eta CSS bidez estilizatu ezinak) edo gure iritzi-estilo pertsonalizatuak HTML eta CSS gehigarriekin.
- Baliotasun mezu pertsonalizatuak
setCustomValidity
eman ditzakezu JavaScript-en.
Hori kontuan izanda, kontuan hartu honako demo hauek gure inprimaki pertsonalizatuak baliozkotzeko estiloetarako, zerbitzariaren aukerako klaseetarako eta arakatzaileen lehenespenetarako.
Estilo pertsonalizatuak
novalidate
Bootstrap inprimakia baliozkotzeko mezu pertsonalizatuetarako, atributu boolearra gehitu beharko duzu zure <form>
. Honek arakatzailearen iritzi-aholku lehenetsiak desgaitzen ditu, baina inprimakiak baliozkotzeko APIetarako sarbidea ematen du JavaScript-en. Saiatu beheko formularioa bidaltzen; gure JavaScript-ek bidaltzeko botoia atzemango dizu eta iritzia emango dizu. Bidaltzen saiatzean, :invalid
eta :valid
estiloak ikusiko dituzu inprimakiaren kontroletan aplikatuta.
Iritzi-estilo pertsonalizatuek kolore pertsonalizatuak, ertzak, foku-estiloak eta atzeko planoko ikonoak aplikatzen dituzte, iritzia hobeto komunikatzeko. S -rako atzeko planoko ikonoak <select>
rekin soilik daude erabilgarri .form-select
, eta ez .form-control
.

Arakatzailearen lehenetsiak
Ez al zaizu interesatzen baliozkotze pertsonalizatuaren iritzi-mezuak edo JavaScript idaztea inprimakiaren jokabideak aldatzeko? Dena ondo, arakatzailearen lehenetsiak erabil ditzakezu. Saiatu beheko formularioa bidaltzen. Zure arakatzailearen eta sistema eragilearen arabera, iritzi-estilo apur bat desberdina ikusiko duzu.
Iritzi-estilo hauek CSS-rekin estiloa jarri ezin badira ere, feedbackaren testua pertsonaliza dezakezu JavaScript bidez.

Zerbitzariaren aldean
.is-invalid
Bezeroaren aldetik baliozkotzea gomendatzen dugu, baina zerbitzariaren aldetik baliozkotzea behar baduzu, baliogabeak eta baliozkoak diren inprimaki-eremuak eta bidez adieraz ditzakezu .is-valid
. Kontuan izan .invalid-feedback
klase hauekin ere onartzen dela.
Baliogabeko eremuetarako, ziurtatu baliogabeko iritzia/errore mezua dagokion inprimaki-eremuarekin erlazionatuta dagoela erabiliz aria-describedby
(kontuan izan atributu honek bat baino gehiagori id
erreferentzia egiteko aukera ematen duela, eremuak dagoeneko inprimakiaren testu gehigarria adierazten badu).
Ertz erradioekin arazoak konpontzeko , sarrera-taldeek .has-validation
klase gehigarri bat behar dute.

Erreminta-aholkuak
Zure inprimakiaren diseinuak aukera ematen badu, .{valid|invalid}-feedback
klaseak klaseengatik alda ditzakezu .{valid|invalid}-tooltip
baliozkotze-erantzunak estiloko tresna-aholku batean bistaratzeko. Ziurtatu guraso bat position: relative
gainean duzula tresna-informazioa kokatzeko. Beheko adibidean, gure zutabe klaseek hori badute dagoeneko, baina baliteke zure proiektuak konfigurazio alternatibo bat behar izatea.

Mapa
Hau da baliozkotzeko Sass mapa _variables.scss
. Gainidatzi edo hedatu hau egoera desberdinak edo gehigarriak sortzeko.
$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
)
);
Maps-ek $form-validation-states
hiru aukerako parametro izan ditzake tresna-aholkuak eta foku-estiloak gainidazteko.
Begizta
Maparen balioen gainean errepikatzeko erabiltzen da $form-validation-states
gure baliozkotze-estiloak sortzeko. Goiko Sass mapan egindako aldaketa guztiak konpilatutako CSS-an islatuko dira begizta honen bidez.
@each $state, $data in $form-validation-states {
@include form-validation-state($state, $data...);
}
Pertsonalizatzea
Balidazio-egoerak Sass bidez pertsonaliza daitezke $form-validation-states
maparekin. Gure fitxategian kokatuta _variables.scss
, Sass mapa hau lehenetsitako valid
/ invalid
baliozkotze egoerak sortzen ditugu. Sartzen da habiaratutako mapa bat, estatu bakoitzaren kolorea, ikonoa, tresna-informazioaren kolorea eta fokuaren itzala pertsonalizatzeko. Arakatzaileek beste estaturik onartzen ez duten arren, estilo pertsonalizatuak erabiltzen dituztenek erraz gehi ditzakete inprimaki-erantzun konplexuagoak.
Kontuan izan ez dugula gomendatzen $form-validation-states
balioak pertsonalizatzea form-validation-state
mixin -a ere aldatu gabe .
