Fa'amaoniga
Tuuina atu ni fa'amatalaga taua, fa'atino i au fa'aoga fa'atasi ai ma le fa'amaoniaina o fomu HTML5, e ala i amioga fa'aletonu ole browser po'o sitaili masani ma le JavaScript.
I luga o lenei itulau
Matou te iloa o le taimi nei o sitaili faʻamaonia aganuʻu masani ma mea faigaluega e le mafai ona maua, talu ai e le o faʻaalia i tekinolosi fesoasoani. A'o matou galulue i se fofo, matou te fautuaina a le o le fa'aogaina o le itu-server filifiliga po'o le fa'aogaina o le su'esu'ega auala fa'amaonia.
E faapefea ona galue
O le auala lenei e galue ai le faʻamaoniaina o pepa ma Bootstrap:
- O le faʻamaoniaina o pepa HTML e faʻaaogaina e ala i le lua pseudo-vasega a le CSS,
:invalidma:valid. E faatatau i<input>,<select>, ma<textarea>elemene. - Bootstrap e fa'apipi'i le
:invalidma:validsitaili i le.was-validatedvasega matua, e masani ona fa'aoga i le<form>. A leai, so'o se fanua mana'omia e aunoa ma se tau e fa'aalia e le aoga ile uta itulau. I lenei auala, e mafai ona e filifili pe o afea e faʻagaoioia ai (e masani lava pe a maeʻa ona taumafai le tuʻuina atu). - Ina ia toe faʻafoʻi foliga o le fomu (mo se faʻataʻitaʻiga, i le tulaga o le tuʻuina atu o pepa faʻamalosi e faʻaaoga ai le AJAX), aveese le
.was-validatedvasega mai le<form>toe tuʻuina atu. - I le avea o se pa'u,
.is-invalidma.is-validvasega e mafai ona faʻaaogaina nai lo le pseudo-vasega mo le faʻamaoniaina o le itu-aumau . Latou te le manaʻomia se.was-validatedvasega matua. - Ona o faʻalavelave i le auala e galue ai le CSS, e le mafai ona matou (i le taimi nei) faʻaoga sitaili i se
<label>mea e sau i luma o le faʻatonutonuina o foliga i le DOM e aunoa ma le fesoasoani a le JavaScript masani. - O su'esu'ega fa'aonaponei uma e lagolagoina le API fa'amaonia fa'atapula'aina , o se fa'asologa o metotia JavaScript mo le fa'amaoniaina o fa'atonuga.
- O fe'au fa'afofoga e mafai ona fa'aoga ai fa'aletonu ole su'esu'ega (ese'ese mo su'esu'ega ta'itasi, ma e le mafai ona fa'aogaina e ala i le CSS) po'o a tatou sitaili fa'aalia fa'apitoa fa'atasi ai ma HTML ma CSS fa'aopoopo.
- E mafai ona e tu'uina atu fe'au fa'ale-aganu'u fa'atatau
setCustomValidityile JavaScript.
Faatasi ai ma lena mea i lou mafaufau, mafaufau i faʻataʻitaʻiga o loʻo mulimuli mai mo a tatou sitaili faʻamaonia pepa masani, vasega i le itu-aumau, ma le faʻaogaina o suʻesuʻega.
Sitaili masani
Mo fe'au fa'amaonia faiga masani a Bootstrap, e mana'omia lou fa'aopoopoina o le novalidateuiga boolean i lau <form>. Ole mea lea e fa'amalo ai le browser default feedback tooltips, ae o lo'o maua pea le avanoa i le fa'amaoniga API i le JavaScript. Taumafai e tu'u le fomu i lalo; o le a fa'alavelaveina e le matou Javascript le fa'amau tu'u mai ma fa'asalalau atu fa'amatalaga ia te oe. A e taumafai e tu'uina atu, e te va'ai i le :invalidma :validsitaili e fa'aoga i au fa'atonuga.
O sitaili fa'aalia fa'apitoa e fa'aoga ai lanu fa'aleaganu'u, tuaoi, sitaili taula'i, ma ata pito i tua e fa'afeso'ota'i lelei ai fa'amatalaga. O ata pito i tua mo <select>s e na'o avanoa i le .form-select, ae le .form-control.
