Tasdiqlash

Brauzerning standart xatti-harakatlari yoki maxsus uslublar va JavaScript orqali HTML5 shakl tekshiruvi yordamida foydalanuvchilarga qimmatli, harakatga mos fikr-mulohazalarni taqdim eting.

Ushbu sahifada
Biz bilamizki, hozirda mijoz tomonidan tekshirishning maxsus uslublari va asboblar maslahatlari mavjud emas, chunki ular yordamchi texnologiyalarga ta'sir qilmaydi. Yechim ustida ishlayotganimizda, server tomoni opsiyasi yoki standart brauzerni tekshirish usulidan foydalanishni tavsiya qilamiz.

U qanday ishlaydi

Formani tekshirish Bootstrap bilan qanday ishlaydi:

  • HTML shaklini tekshirish CSS ning ikkita psevdo-sinfi orqali qo'llaniladi :invalidva :valid. U <input>, <select>, va <textarea>elementlari uchun amal qiladi.
  • Bootstrap :invalidva :validuslublarini ota- .was-validatedklassga qamrab oladi, odatda <form>. Aks holda, qiymatsiz istalgan kerakli maydon sahifa yuklanishida yaroqsiz deb ko'rsatiladi. Shunday qilib, siz ularni qachon faollashtirishni tanlashingiz mumkin (odatda ariza yuborishga urinishdan keyin).
  • Shaklning ko'rinishini tiklash uchun (masalan, AJAX yordamida dinamik shakllar yuborilganda), topshirilgandan so'ng .was-validatedsinfni <form>qaytadan olib tashlang.
  • Zaxira sifatida .is-invalidva server tomonidan tekshirish.is-valid uchun psevdo-sinflar o'rniga sinflar ishlatilishi mumkin . Ular ota-ona sinfini talab qilmaydi ..was-validated
  • CSS qanday ishlashidagi cheklovlar tufayli biz (hozirda) DOMda <label>forma boshqaruvidan oldin kelgan uslublarni maxsus JavaScript yordamisiz qo'llay olmaymiz.
  • Barcha zamonaviy brauzerlar cheklovni tekshirish API ni, shakl boshqaruvlarini tekshirish uchun JavaScript usullari qatorini qo'llab-quvvatlaydi.
  • Fikr-mulohaza xabarlari brauzerning standart sozlamalaridan (har bir brauzer uchun har xil va CSS orqali beqaror) yoki qo‘shimcha HTML va CSS bilan maxsus fikr-mulohaza uslublarimizdan foydalanishi mumkin.
  • setCustomValiditySiz JavaScript-da maxsus haqiqiylik xabarlarini taqdim etishingiz mumkin .

Shuni yodda tutgan holda, bizning shaxsiy shaklni tekshirish uslublarimiz, ixtiyoriy server tomoni sinflari va brauzerning standart sozlamalari uchun quyidagi demolarni ko'rib chiqing.

Maxsus uslublar

Maxsus Bootstrap formasini tekshirish xabarlari uchun novalidateboolean atributini <form>. Bu brauzerning birlamchi fikr-mulohazalarini bildirish bo‘yicha maslahatlarini o‘chirib qo‘yadi, lekin shunga qaramay JavaScript-da shaklni tekshirish API-lariga kirish imkonini beradi. Quyidagi shaklni topshirishga harakat qiling; bizning JavaScript jo'natish tugmachasini to'xtatadi va sizga fikr-mulohazalarni yuboradi. Yuborishga urinayotganda siz shakl boshqaruv elementlariga qo‘llanilgan :invalidva uslublarni ko‘rasiz .:valid

Maxsus fikr-mulohaza uslublari fikr-mulohazalarni yaxshiroq etkazish uchun maxsus ranglar, chegaralar, fokus uslublari va fon piktogrammalarini qo'llaydi. s uchun fon piktogrammalari <select>faqat mavjud .form-selectva mavjud emas .form-control.

Brauzerning standart sozlamalari

Shakl xatti-harakatlarini o'zgartirish uchun maxsus tekshirish bo'yicha fikr-mulohaza xabarlari yoki JavaScript yozish qiziq emasmi? Hammasi yaxshi, siz brauzerning standart sozlamalaridan foydalanishingiz mumkin. Quyidagi shaklni topshirishga harakat qiling. Brauzeringiz va operatsion tizimingizga qarab, siz bir oz boshqacha fikr-mulohazalarni ko'rasiz.

Ushbu fikr-mulohaza uslublarini CSS bilan shakllantirish mumkin bo'lmasa-da, siz hali ham JavaScript orqali fikr-mulohaza matnini sozlashingiz mumkin.

Server tomoni

Mijoz tomonidan tekshirishdan foydalanishni tavsiya qilamiz, lekin agar sizga server tomoni tekshiruvi kerak bo'lsa, yaroqsiz va yaroqsiz shakl maydonlarini va bilan ko'rsatishingiz .is-invalidmumkin .is-valid. E'tibor bering, .invalid-feedbackushbu sinflar ham qo'llab-quvvatlanadi.

Yaroqsiz maydonlar uchun noto'g'ri fikr-mulohaza/xato xabari tegishli shakl maydoni bilan bog'langanligiga ishonch hosil qiling ( agar maydon qo'shimcha shakl matniga ishora aria-describedbyqilsa, bu atribut bir nechta havola qilish imkonini beradi ).id

Chegara radiuslari bilan bog'liq muammolarni tuzatish uchun kirish guruhlari qo'shimcha .has-validationsinfni talab qiladi.

Xarita

Bu tekshirish Sass xaritasi _variables.scss. Turli yoki qo'shimcha holatlar yaratish uchun buni bekor qiling yoki kengaytiring.

$form-validation-states: (
  "valid": (
    "color": $form-feedback-valid-color,
    "icon": $form-feedback-icon-valid
  ),
  "invalid": (
    "color": $form-feedback-invalid-color,
    "icon": $form-feedback-icon-invalid
  )
);

Xaritalar $form-validation-statesmaslahatlar va fokus uslublarini bekor qilish uchun uchta ixtiyoriy parametrni o'z ichiga olishi mumkin.

Loop

$form-validation-statesTasdiqlash uslublarimizni yaratish uchun xarita qiymatlarini takrorlash uchun foydalaniladi. Yuqoridagi Sass xaritasiga kiritilgan har qanday o'zgartirishlar ushbu tsikl orqali tuzilgan CSS-da aks ettiriladi.

@each $state, $data in $form-validation-states {
  @include form-validation-state($state, $data...);
}

Moslashtirish

$form-validation-statesTasdiqlash holatlari xarita bilan Sass orqali sozlanishi mumkin . Bizning faylimizda joylashgan _variables.scssushbu Sass xaritasi biz standart valid/ invalidtasdiqlash holatlarini qanday yaratamiz. Har bir shtatning rangi, belgisi, asboblar paneli rangi va fokus soyasini moslashtirish uchun ichki xarita kiritilgan. Boshqa hech qanday shtat brauzerlar tomonidan qo'llab-quvvatlanmasa-da, maxsus uslublardan foydalanadiganlar osonlikcha murakkabroq shakldagi fikr-mulohazalarni qo'shishlari mumkin.
