Barlamak

Supporthli goldaýan brauzerlerimizde bar bolan HTML5 formasyny tassyklamak bilen ulanyjylaryňyza gymmatly, täsirli jogap beriň . Brauzeriň deslapky tassyklama seslenmesini saýlaň ýa-da içerki synplarymyz we başlangyç JavaScript bilen ýörite habarlary ýerine ýetiriň.

Häzirki wagtda ýerli brauzerde başlangyç tassyklama habarlary ähli brauzerlerde kömekçi tehnologiýalara yzygiderli täsir etmeýär (esasanam, iş stoly we ykjamda Chrome), adaty tassyklama stillerini ulanmagy maslahat berýäris.

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 .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 forma tassyklama stillerimiz, islege bagly serwer gapdal synplary we brauzer defoltlary üçin aşakdaky demleri göz öňünde tutuň.

Omörite stiller

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.
