Ukuqinisekisa
Nikeza ngempendulo ebalulekile, ebambekayo kubasebenzisi bakho ngokuqinisekiswa kwefomu le-HTML5, ngokuziphatha okuzenzakalelayo kwesiphequluli noma izitayela zangokwezifiso kanye ne-JavaScript.
Isebenza kanjani
Nakhu ukuthi ukuqinisekiswa kwefomu kusebenza kanjani nge-Bootstrap:
- Ukuqinisekiswa kwefomu le-HTML kusetshenziswa ngamakilasi amabili mbumbulu we-CSS,
:invalid
kanye:valid
. Isebenza ku-<input>
,<select>
, kanye<textarea>
nezakhi. - I-Bootstrap ihlanganisa izitayela
:invalid
nezitayela ekilasini:valid
labazali.was-validated
, ngokuvamile zisetshenziswa kufayela le-<form>
. Uma kungenjalo, noma iyiphi inkambu edingekayo engenavelu ibonakala njengengavumelekile ekulayisheni kwekhasi. Ngale ndlela, ungakhetha ukuthi uzozivula nini (imvamisa ngemuva kokuzanywa kokuthunyelwa kwefomu). - Ukuze usethe kabusha ukubukeka kwefomu (ngokwesibonelo, esimweni sokuhanjiswa kwamafomu aguquguqukayo kusetshenziswa i-AJAX), susa
.was-validated
ikilasi kusukela<form>
futhi ngemva kokuhambisa. - Njengembuyiselo,
.is-invalid
futhi.is-valid
amakilasi angasetshenziswa esikhundleni samakilasi mbumbulu wokuqinisekisa ohlangothini lweseva . Abadingi.was-validated
ikilasi labazali. - Ngenxa yemikhawulo endleleni i-CSS esebenza ngayo, asikwazi (okwamanje) ukusebenzisa izitayela
<label>
kulokho okuza ngaphambi kokulawula kwefomu ku-DOM ngaphandle kosizo lweJavaScript yangokwezifiso. - Zonke iziphequluli zesimanje zisekela i- API yokuqinisekisa umkhawulo , uchungechunge lwezindlela ze-JavaScript zokuqinisekisa izilawuli zefomu.
- Imilayezo yempendulo ingase isebenzise okumisiwe kwesiphequluli (okuhlukile kusiphequluli ngasinye, futhi akunasitayela nge-CSS) noma izitayela zethu zempendulo zangokwezifiso nge-HTML ne-CSS eyengeziwe.
- Unganikeza imilayezo yokuqinisekisa ngokwezifiso nge
setCustomValidity
-JavaScript.
Unalokho engqondweni, cabangela amademo alandelayo ezitayela zethu zokuqinisekisa amafomu angokwezifiso, amakilasi okuzithandela aseceleni kweseva, nokuzenzakalelayo kwesiphequluli.
Izitayela ngokwezifiso
Ukuze uthole imilayezo yokuqinisekisa yefomu le-Bootstrap yangokwezifiso, uzodinga ukungeza novalidate
isibaluli se-boolean kufayela lakho le- <form>
. Lokhu kukhubaza amathiphu empendulo ezenzakalelayo yesiphequluli, kodwa kusahlinzeka ngokufinyelela kuma-API okuqinisekisa amafomu ku-JavaScript. Zama ukuhambisa leli fomu elingezansi; I-JavaScript yethu izobamba inkinobho yokuhambisa futhi idlulisele kuwe impendulo. Uma uzama ukuthumela, uzobona izitayela :invalid
nezitayela :valid
zisetshenziswa kuzilawuli zakho zefomu.
Izitayela zempendulo yangokwezifiso zisebenzisa imibala yangokwezifiso, imingcele, izitayela zokugxila, nezithonjana zangemuva ukuze kudluliselwe impendulo kangcono. Izithonjana zangemuva ze- <select>
s zitholakala kuphela nge- .form-select
, hhayi .form-control
.

Okuzenzakalelayo kwesiphequluli
Awunantshisekelo kumilayezo yempendulo yokuqinisekisa ngokwezifiso noma ukubhala i-JavaScript ukuze ushintshe indlela yokuziphatha yefomu? Konke kuhle, ungasebenzisa okuzenzakalelayo kwesiphequluli. Zama ukuthumela ifomu elingezansi. Ngokuya ngesiphequluli sakho ne-OS, uzobona isitayela esihluke kancane sempendulo.
Yize lezi zitayela zempendulo zingenakwenziwa isitayela nge-CSS, usengawenza ngendlela oyifisayo umbhalo wempendulo nge-JavaScript.

Uhlangothi lweseva
Sincoma ukusebenzisa ukuqinisekiswa kohlangothi lweklayenti, kodwa uma udinga ukuqinisekiswa kohlangothi lweseva, ungabonisa izinkambu zefomu ezingavumelekile nezivumelekile .is-invalid
nge- .is-valid
. Qaphela ukuthi .invalid-feedback
futhi kuyasekelwa nalawa makilasi.
Ezinkambuni ezingavumelekile, qinisekisa ukuthi impendulo/umlayezo wephutha ongavumelekile uhlotshaniswa nenkambu yefomu efanele kusetshenziswa aria-describedby
(uphawula ukuthi lesi sibaluli sivumela okungaphezu kweyodwa id
ukuthi kubhekiselwe kuso, uma kwenzeka inkambu isivele ikhomba umbhalo wefomu owengeziwe).
Ukuze ulungise izinkinga ngerediya yomngcele , amaqembu okokufaka adinga iklasi elengeziwe .has-validation

Uma isakhiwo sakho sefomu sikuvumela, ungashintsha .{valid|invalid}-feedback
amakilasi .{valid|invalid}-tooltip
ukuze ubonise impendulo yokuqinisekisa ethiphu yamathuluzi enesitayela. Qiniseka ukuthi position: relative
unomzali okhona ukuze amise ithiphu lamathuluzi. Esibonelweni esingezansi, amakilasi ethu ekholomu asenakho lokhu, kodwa iphrojekthi yakho ingase idinge okunye ukusetha.

Imephu
Leli imephu yokuqinisekisa ye-Sass evela ku- _variables.scss
. Khipha noma unwebe lokhu ukuze ukhiqize izifunda ezihlukile noma ezengeziwe.
$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
)
);
Amamephu we- $form-validation-states
angaqukatha amapharamitha amathathu ongawakhetha ukuze akhiphe amathiphu wamathuluzi nezitayela zokugxila.
Iluphu
Isetshenziselwa ukuphindaphinda $form-validation-states
amanani emephu ukuze kukhiqizwe izitayela zethu zokuqinisekisa. Noma yikuphi ukuguqulwa kumephu ye-Sass engenhla kuzobonakala ku-CSS yakho ehlanganisiwe ngale loop.
@each $state, $data in $form-validation-states {
@include form-validation-state($state, $data...);
}
Ukwenza ngokwezifiso
Izimo zokuqinisekisa zingenziwa ngendlela oyifisayo nge-Sass $form-validation-states
ngemephu. Itholakala _variables.scss
kufayela lethu, le mephu ye-Sass yindlela esenza ngayo izimo ezizenzakalelayo valid
/ invalid
zokuqinisekisa. Kufakwe imephu ebekiwe yokwenza ngokwezifiso umbala wesifunda ngasinye, isithonjana, umbala wethiphu yamathuluzi, nesithunzi sokugxilisa kuso. Nakuba zingekho ezinye izifunda ezisekelwa iziphequluli, lezo ezisebenzisa izitayela zangokwezifiso zingangeza kalula impendulo yefomu eyinkimbinkimbi.
Sicela uqaphele ukuthi asincomi ukwenza $form-validation-states
amanani ngendlela oyifisayo ngaphandle kokushintsha i- form-validation-state
mixin .
