Kufikika

Onetsetsani kuti muwonjezere aria-expandedku chinthu chowongolera. Izi zikuwonetsa bwino momwe zinthu zomwe zimasokonekera zomwe zimalumikizidwa ndi zowongolera zowerengera zowonera ndi matekinoloje othandizira ofanana. Ngati chinthu chosokonekera chatsekedwa mwachisawawa, mawonekedwe omwe ali pagawo lowongolera ayenera kukhala ndi mtengo wa aria-expanded="false". Ngati mwakhazikitsa chinthu chogonja kuti chitsegulidwe mwachisawawa pogwiritsa ntchito showkalasi, ikani aria-expanded="true"pazowongolera m'malo mwake. Pulagiyi imangosintha izi poyang'anira kutengera ngati chinthu chomwe chitha kugubuduka chatsegulidwa kapena ayi (kudzera JavaScript, kapena chifukwa wogwiritsa ntchitoyo adayambitsa chinthu china chowongolera chomwe chimamangiriridwanso ku chinthu chomwecho). Ngati chinthu chowongolera cha HTML si batani (mwachitsanzo, <a>kapena <div>), mawonekedwerole="button"ziyenera kuwonjezeredwa ku element.

Ngati chinthu chomwe mumayang'anira chikuyang'ana chinthu chimodzi chomwe chimatha kugwa - mwachitsanzo, mawonekedwewo data-targetakulozera kwa idchosankha - muyenera kuwonjezera chizindikiritso aria-controlsku chinthu chowongolera, chomwe chili ndi idchinthu chomwe chimatha kugwa. Owerenga zenera amakono ndi matekinoloje othandizira ofanana amagwiritsa ntchito izi kuti apatse ogwiritsa ntchito njira zazifupi kuti ayende molunjika ku chinthu chomwe chimasokonekera chokha.

Dziwani kuti kukhazikitsidwa kwa Bootstrap pakadali pano sikukhudzana ndi machitidwe osiyanasiyana a kiyibodi ofotokozedwa mu WAI-ARIA Authoring Practices 1.1 accordion pattern - muyenera kuziphatikiza ndi JavaScript yokhazikika.

Kugwiritsa ntchito

Pulagi yakugwa imagwiritsa ntchito makalasi angapo kuti athetse kukweza kolemera:

.collapseamabisa zomwe zili
.collapse.showzikuwonetsa zomwe zili
.collapsingimawonjezeredwa pamene kusintha kukuyamba, ndikuchotsedwa ikatha

Maphunzirowa amapezeka mu _transitions.scss.

Kudzera muzochita za data

Ingowonjezerani data-toggle="collapse"ndi a data-targetku chinthucho kuti muzipereka chiwongolero cha chinthu chimodzi kapena zingapo zomwe zimatha kutha. Malingaliro data-targetamavomereza chosankha cha CSS kuti agwiritse ntchito kugwa. Onetsetsani kuti mwawonjezera kalasi collapseku chinthu chomwe chimatha. Ngati mukufuna kuti isatseguke, onjezani kalasi yowonjezera show.

Kuti muwonjeze kasamalidwe ka gulu ngati accordion kumalo otha kugwa, onjezani mawonekedwe a data data-parent="#selector". Onani pachiwonetsero kuti muwone izi zikugwira ntchito.

Kudzera pa JavaScript

Yambitsani pamanja ndi:

$('.collapse').collapse()

Zosankha

Zosankha zitha kuperekedwa kudzera pa data kapena JavaScript. Pamawonekedwe a data, yonjezerani dzina lachisankho ku data-, monga mu data-parent="".

Njira

Asynchronous njira ndi kusintha

Njira zonse za API ndizosasinthika ndipo zimayamba kusintha . Amabwerera kwa woyimbirayo atangoyamba kusintha koma asanathe . Kuonjezera apo, kuyitana kwa njira pa gawo losintha kudzanyalanyazidwa .

Onani zolemba zathu za JavaScript kuti mudziwe zambiri .

`.collapse(options)`

Imatsegula zomwe zili ngati chinthu chomwe chimatha kutha. Imavomereza zomwe mungachite object.

$('#myCollapsible').collapse({
  toggle: false
})

`.collapse('toggle')`

Imasintha zinthu zomwe zimagundika kuti ziwonetsedwe kapena zobisika. Imabwereranso kwa woyimbayo chinthu chomwe chingathe kutha sichinasonyezedwe kapena kubisika (ie chisanachitike shown.bs.collapsekapena hidden.bs.collapsechochitikacho).

`.collapse('show')`

Imawonetsa chinthu chomwe chimatha kutha. Imabwereranso kwa woyimbayo chinthu chomwe chingathe kugwetsedwa chisanasonyezedwe (mwachitsanzo, shown.bs.collapsechochitikacho chisanachitike).

`.collapse('hide')`

Imabisa chinthu chomwe chimatha kutha. Imabwereranso kwa woyimbirayo chinthu chosokonekera chisanabisike (mwachitsanzo, hidden.bs.collapsechochitikacho chisanachitike).

`.collapse('dispose')`

Imawononga kugwa kwa chinthu.

Zochitika

Gulu la kugwa la Bootstrap limawulula zochitika zingapo kuti zigwirizane ndi kugwa.
