Kumaha gawéna

Ieu kumaha validasi formulir tiasa dianggo sareng Bootstrap:

  • Validasi formulir HTML diterapkeun via dua kelas pseudo CSS, :invalidsareng :valid. Ieu lumaku pikeun <input>, <select>, sarta <textarea>elemen.
  • Bootstrap wengkuan :invalidsareng :validgaya ka kelas indungna .was-validated, biasana dilarapkeun kana <form>. Upami teu kitu, widang naon waé anu dibutuhkeun tanpa niléy némbongan sah dina beban halaman. Ku cara ieu, anjeun tiasa milih iraha ngaktipkeunana (biasana saatos kiriman formulir dicoba).
  • Pikeun ngareset penampilan formulir (contona, dina kasus kiriman formulir dinamis maké AJAX), cabut .was-validatedkelas ti <form>deui sanggeus kaluman.
  • Salaku fallback a, .is-invalidsarta .is-validkelas bisa dipaké gaganti pseudo-kelas pikeun validasi sisi server . Aranjeunna teu merlukeun .was-validatedkelas indungna.
  • Alatan konstrain dina cara CSS jalan, urang teu bisa (ayeuna) nerapkeun gaya ka <label>nu asalna saméméh kontrol formulir di DOM tanpa bantuan custom JavaScript.
  • Sadaya panyungsi modéren ngarojong API validasi konstrain , runtuyan métode JavaScript pikeun ngavalidasi kontrol formulir.
  • Talatah eupan balik bisa ngagunakeun standar browser (béda pikeun tiap browser, sarta unstylable via CSS) atawa gaya eupan balik custom kami kalawan tambahan HTML jeung CSS.
  • Anjeun tiasa nyayogikeun pesen validitas khusus setCustomValiditydina JavaScript.

Kalayan émut éta, pertimbangkeun demo di handap ieu pikeun gaya validasi formulir khusus urang, kelas sisi server opsional, sareng standar browser.
