Whakamana
Homai he urupare utu nui, whaihua ki o kaiwhakamahi me te whakamana i te puka HTML5, ma nga whanonga taunoa o te tirotiro me nga momo ritenga me te JavaScript.
I tenei wharangi
Kei te mohio matou i tenei wa kaore e taea te uru atu ki nga ahua o te taha-kiritaki me nga aki taputapu, na te mea kaore e kitea ki nga hangarau awhina. I a matou e mahi ana i tetahi otinga, ka tūtohu matou ki te whakamahi i te kowhiringa taha-tumau, te tikanga whakamana tirotiro taunoa ranei.
Pehea te mahi
Anei te mahi whakamana puka me Bootstrap:
- Ko te whakamana puka HTML ka whakamahia ma nga akomanga pseudo e rua a CSS,
:invalidme te:valid. Ka pa ki te<input>,<select>, me<textarea>nga huānga. - Ka horahia e Bootstrap nga momo
:invalidme:validnga momo ki te.was-validatedakomanga matua, ka whakamahia ki te<form>. Ki te kore, ko nga mara e hiahiatia ana kaore he uara ka kitea he muhu i runga i te utaina wharangi. Ma tenei ara, ka taea e koe te whiriwhiri i te wa e whakahohehia ai (te nuinga i muri i te nganatanga o te tuku puka). - Hei tautuhi i te ahua o te puka (hei tauira, mo te tukunga puka hihiri ma te whakamahi i te AJAX), tangohia te
.was-validatedkaraehe mai i te<form>reanga i muri i te tukunga. - Hei whakamuri, ka whakamahia
.is-invalidpea.is-validnga karaehe hei utu mo nga karaehe pseudo mo te whakamanatanga taha-tumau . Kaore e hiahiatia he.was-validatedakomanga matua. - Na nga herenga o te mahi a CSS, kaore e taea e matou (i tenei wa) te whakamahi i nga momo ki tetahi
<label>ka puta mai i mua i te mana o te puka i roto i te DOM kaore he awhina a JavaScript. - Ka tautoko nga kaitirotiro hou katoa i te API whakamana herenga , he raupapa o nga tikanga JavaScript mo te whakamana i nga mana puka.
- Ka taea e nga karere urupare te whakamahi i nga taunoa o te kaitirotiro (he rereke mo ia kaitirotiro, me te kore e taea te tuhi ma te CSS) me o maatau momo urupare me etahi atu HTML me CSS.
- Ka taea e koe te tuku karere whaimana ritenga ki
setCustomValidityroto i te JavaScript.
Ma te mahara ki tera, whakaarohia nga whakaaturanga e whai ake nei mo o taatau momo ahua whakamana, nga karaehe taha-tumau, me nga hapa tirotiro.
Nga momo ritenga
Mo nga karere whakamana puka Bootstrap ritenga, me taapiri koe i te novalidatehuanga boolean ki to <form>. Ka mono tenei i nga aki taputapu urupare taunoa, engari ka uru tonu ki nga API whakamana puka i roto i te JavaScript. Ngana ki te tuku i te puka kei raro nei; ka haukotia e ta maatau JavaScript te paatene tuku me te tuku urupare ki a koe. I te wa e ngana ana ki te tuku, ka kite koe i nga momo :invalidme :validnga momo e pa ana ki o mana puka.
Ka whakamahia e nga momo urupare ritenga nga tae ritenga, nga taitapa, nga momo arotahi, me nga tohu papamuri kia pai ake ai te korero urupare. Ko nga tohu papamuri mo <select>s kei te waatea noa me te .form-select, kaore .form-control.

Kaore koe e aro ki nga karere urupare whakamana ritenga, ki te tuhi JavaScript ranei hei whakarereke i nga whanonga puka? He pai katoa, ka taea e koe te whakamahi i nga taunoa pūtirotiro.

Ka tūtohu matou ki te whakamahi i te whakamanatanga taha-kiritaki, engari ki te hiahia koe ki te whakamana i te taha-tumau, ka taea e koe te tohu i nga waahanga puka muhu me te whaimana .is-invalidme te .is-valid. Kia mahara kei .invalid-feedbackte tautokohia ano e enei akomanga.

Koinei te whakamanatanga mapi Sass mai i _variables.scss. Takahia, whakaroahia ranei tenei ki te whakaputa i nga ahuatanga rereke, taapiri ranei.

"icon": $form-feedback-icon-valid
),
"invalid": (
"color": $form-feedback-invalid-color,
"icon": $form-feedback-icon-invalid
)
);
Ka taea e nga Mahere o $form-validation-stateste toru nga tawhā hei whakakore i nga aki taputapu me nga momo arotahi.
Porowhita
Ka whakamahia ki te huri $form-validation-statesi nga uara mapi hei whakaputa i o maatau momo whakamana. Ko nga whakarereketanga ki te mapi Sass i runga ake nei ka kitea i roto i to CSS kua whakahiato ma tenei kopikopiko.
@each $state, $data in $form-validation-states {
@include form-validation-state($state, $data...);
}
Whakaritea
Ko nga ahuatanga whakamana ka taea te whakarite ma te Sass me te $form-validation-statesmapi. Kei roto i ta maatau _variables.scsskonae, ko tenei mapi Sass te ahua o te whakaputa i nga ahuatanga taunoa valid/ invalidwhakamana. Kei roto ko te mahere kohanga hei whakarite i te tae o ia kawanatanga, te ata, te tae taputapu, me te atarangi arotahi. Ahakoa kaore etahi atu whenua e tautokohia ana e nga kaitirotiro, ka taea e te hunga e whakamahi ana i nga momo ritenga te taapiri i nga urupare puka uaua ake.
