Caveat ndi anangula

Mwachikhazikitso, asakatuli azitha kuyang'anira mawonekedwe onse ( <input>, <select>ndi <button>zinthu) mkati <fieldset disabled>mwazolephereka, kulepheretsa kuyanjana kwa kiyibodi ndi mbewa pa iwo. Komabe, ngati mawonekedwe anu alinso ndi <a ... class="btn btn-*">zinthu, izi zidzangopatsidwa kalembedwe ka pointer-events: none. Monga tafotokozera m'chigawo chokhudza mabatani olemala (ndipo makamaka mugawo laling'ono la nangula), katundu wa CSS sanakhazikitsidwebe ndipo sakuthandizidwa mokwanira mu Opera 18 ndi pansi, kapena mu Internet Explorer 10, ndipo adapambana. 'Letsani ogwiritsa ntchito kiyibodi kuti azitha kuyang'ana kapena kuyambitsa maulalo awa. Chifukwa chake kuti mukhale otetezeka, gwiritsani ntchito JavaScript kuti mulepheretse maulalo oterowo.

Kugwirizana kwa msakatuli

Ngakhale Bootstrap idzagwiritsa ntchito masitayelo awa mu asakatuli onse, Internet Explorer 11 ndi pansipa sizigwirizana ndi disabledmawonekedwe a <fieldset>. Gwiritsani ntchito JavaScript yokhazikika kuti muyimitse gawo la asakatuli awa.

Kutsimikizira

Perekani mayankho ofunika, otheka kwa ogwiritsa ntchito anu potsimikizira mafomu a HTML5- omwe amapezeka m'masakatuli athu onse othandizidwa . Sankhani kuchokera pa msakatuli wotsimikizira zotsimikizira, kapena gwiritsani ntchito mauthenga omwe mwamakonda ndi makalasi athu omangidwira ndikuyambitsa JavaScript.

Timalimbikitsa kwambiri masitayelo ovomerezeka chifukwa zosasintha za msakatuli sizilengezedwa kwa owerenga.

Momwe zimagwirira ntchito

Umu ndi momwe kutsimikizira mawonekedwe kumagwirira ntchito ndi Bootstrap:

  • Kutsimikizika kwa mawonekedwe a HTML kumagwiritsidwa ntchito kudzera m'makalasi awiri achinyengo a CSS, :invalidndi :valid. Zimakhudza <input>, <select>, ndi <textarea>zinthu.
  • Bootstrap imayang'ana :invalidndi :validmasitayelo ku .was-validatedkalasi ya makolo, nthawi zambiri amagwiritsidwa ntchito ku <form>. Kupanda kutero, gawo lililonse lofunikira lopanda mtengo likuwoneka ngati losavomerezeka pamasamba. Mwanjira iyi, mutha kusankha nthawi yoti muyambitse (nthawi zambiri mukayesa kutumiza fomu).
  • Monga kubweza, .is-invalidndipo .is-validmakalasi atha kugwiritsidwa ntchito m'malo mwa pseudo-class pakutsimikizira mbali ya seva . Safuna .was-validatedkalasi ya makolo.
  • Chifukwa cha zopinga momwe CSS imagwirira ntchito, sitingathe (pakali pano) kugwiritsa ntchito masitayelo ku <label>omwe amabwera patsogolo pa mawonekedwe mu DOM popanda kuthandizidwa ndi JavaScript.
  • Asakatuli onse amakono amathandizira API yotsimikizira zoletsa , njira zingapo za JavaScript zotsimikizira kuwongolera mawonekedwe.
  • Mauthenga oyankha atha kugwiritsa ntchito zosasintha za msakatuli (zosiyana pa msakatuli uliwonse, komanso zosalembedwera kudzera pa CSS) kapena masitayelo athu ofotokozera omwe ali ndi HTML ndi CSS yowonjezera.
  • Mutha kupereka mauthenga ovomerezeka ndi setCustomValidityJavaScript.

Poganizira izi, lingalirani ma demo otsatirawa a masitayelo athu otsimikizira mawonekedwe, makalasi am'mbali mwa seva, ndi kusasintha kwa msakatuli.

Masitayelo mwamakonda

Kwa mauthenga otsimikizira mawonekedwe a Bootstrap, muyenera kuwonjezera mawonekedwe a novalidateboolean ku fayilo yanu ya <form>. Izi zimayimitsa zida zosinthira msakatuli, komabe zimapereka mwayi wopeza ma API otsimikizira mu JavaScript. Yesani kutumiza fomu ili pansipa; JavaScript yathu idumpha batani lotumiza ndikutumiza ndemanga kwa inu.

Mukayesa kutumiza, muwona mawonekedwe :invalidndi :validmasitayelo akugwiritsidwa ntchito pazowongolera mafomu anu.
