Barlamak

Brauzeriň adaty hereketleri ýa-da adaty stilleri we JavaScript arkaly HTML5 formasyny tassyklamak bilen ulanyjylaryňyza gymmatly, täsirli jogap beriň.

Bu sahypada
Müşderi tarapyndan ýöriteleşdirilen tassyklama stilleriniň we gural görkezmeleriniň elýeterli däldigini bilýäris, sebäbi kömekçi tehnologiýalara sezewar bolmaýarlar. Çözüwiň üstünde işleýänimizde, ýa-da serwer tarapyny ýa-da deslapky brauzeri tassyklamak usulyny ulanmagy maslahat bereris.

Bu nähili işleýär

“Bootstrap” bilen forma tassyklamasynyň nähili işleýändigi:

  • HTML formasyny barlamak CSS-iň iki sany ýasama synpy arkaly ulanylýar :invalidwe :valid. Bu elementlere degişlidir <input>.<select><textarea>
  • “Bootstrap” , adatça ulanylýan ene-atalar synpyna :invalidwe :validstiline degişlidir . Otherwiseogsam, gymmaty bolmadyk islendik meýdan sahypa ýükünde nädogry görkezilýär. Şeýlelik bilen, haçan işjeňleşdirmelidigini saýlap bilersiňiz (adatça forma tabşyrylansoň)..was-validated<form>
  • Formanyň daşky görnüşini täzeden düzmek üçin (mysal üçin, AJAX ulanyp dinamiki forma iberen ýagdaýynda), tabşyranyňyzdan soň .was-validatedsynpy <form>täzeden aýyryň.
  • Yza gaýdyp gelmek hökmünde .is-invalidwe serwer tarapyny barlamak.is-valid üçin pseudo-synplaryň ýerine sapaklar ulanylyp bilner . Ene-atalar synpyny talap etmeýärler ..was-validated
  • CSS-iň işleýşindäki çäklendirmeler sebäpli, häzirki <label>JavaScript-iň kömegi bolmazdan, DOM-da forma gözegçilikden öň gelýän stilleri ulanyp bilmeris.
  • Modernhli döwrebap brauzerler , forma dolandyryşlaryny barlamak üçin JavaScript usullarynyň bir topary bolan çäklendirme tassyklama API -ni goldaýarlar.
  • Seslenme habarlary brauzeriň defoltlaryny (her brauzer üçin tapawutly we CSS arkaly üýtgedip bolmaýar) ýa-da goşmaça HTML we CSS bilen adaty sesleniş usullarymyzy ulanyp biler.
  • setCustomValidityJavaScript-de ýörite ygtybarlylyk habarlaryny berip bilersiňiz.

Şuny göz öňünde tutup, adaty formany tassyklamak stillerimiz, serweriň goşmaça synplary we brauzer defoltlary üçin aşakdaky demleri göz öňünde tutuň.

Omörite stiller

novalidateBoörite “Bootstrap” formasyny tassyklamak habarlary üçin size “ boolean” atributyny goşmaly bolarsyňyz <form>. Bu, brauzeriň deslapky seslenme gurallaryny öçürýär, ýöne şonda-da JavaScript-de forma tassyklama API-lerine girişi üpjün edýär. Aşakdaky formany ibermäge synanyşyň; JavaScriptimiz tabşyrmak düwmesini saklar we size jogap berer. Ibermäge synanyşanyňyzda , forma dolandyryşlaryňyza ulanylýan stilleri :invalidwe stilleri görersiňiz .:valid

Feedbackörite seslenme stilleri has gowy habarlaşmak üçin ýörite reňkleri, serhetleri, fokus stillerini we fon nyşanlaryny ulanýar. S üçin fon nyşanlary <select>diňe elýeterli .form-select, ýok .form-control.
