Ukuwa

Guqula ukubonakala komxholo kuyo yonke iprojekthi yakho ngeeklasi ezimbalwa kunye neeplagi zethu zeJavaScript.

Ingaba isebenza kanjani

Iplagi yeJavaScript yokudilika isetyenziselwa ukubonisa nokufihla umxholo. Amaqhosha okanye iiankile zisetyenziswa njengezinto ezibangela ukuba zenziwe kwimaphu kwizinto ezithile oziguqulayo. Ukuthoba isiqalelo kuyakuphilisa ixabiso heightlayo langoku ukuya kwi 0. Unikwe indlela iCSS ephatha ngayo oopopayi, awukwazi ukusebenzisa paddinginto .collapseethile. Endaweni yoko, sebenzisa iklasi njengento ezimeleyo yokusonga.

Isiphumo soopopayi seli candelo sixhomekeke prefers-reduced-motionkumbuzo wemidiya. Jonga icandelo leentshukumo ezincitshisiweyo kuxwebhu lwethu lofikelelo .

Umzekelo

Cofa amaqhosha angezantsi ukuze ubonise kwaye ufihle enye into ngotshintsho lweklasi:

.collapseifihla umxholo
.collapsingisetyenziswa ngexesha lotshintsho
.collapse.showibonisa umxholo

Ungasebenzisa ikhonkco kunye hrefnophawu, okanye iqhosha elinophawu data-targetloyelelwano. Kuzo zombini ezi meko, data-toggle="collapse"kuyafuneka.

Ikhonkco ne- href

Ukufikeleleka

Qinisekisa ukuba wongeza aria-expandedkwinto yolawulo. Olu phawu lubonisa ngokucacileyo imeko yangoku yento eqengqelekayo ebotshelelwe kulawulo kwizifundi zesikrini kunye nobuchwephesha obuncedisayo obufanayo. Ukuba into eqengqelekayo ivalwe ngokungagqibekanga, uphawu loyelelwano lwento yolawulo kufuneka lube nexabiso aria-expanded="false". Ukuba usete into eqengqelekayo ukuba ivuleke ngokungagqibekanga usebenzisa showiklasi, misela aria-expanded="true"kulawulo endaweni yoko. Iplagi iya kuzitshintsha ngokuzenzekela olu phawu kulawulo olusekwe ekubeni ngaba into eqengqelekayo ivuliwe okanye ayivalwanga (ngeJavaScript, okanye kuba umsebenzisi eqalise enye into yolawulo nayo ibotshelelwe kwinto enye eqengqelekayo). Ukuba isiqalelo solawulo se HTML asiloqhosha (umzekelo, i <a>okanye <div>), uphawurole="button"kufuneka yongezwe kwisiqalelo.

Ukuba isiqalelo sakho solawulo sijolise kwinto enye eqengqelekayo - oko kukuthi data-targetuphawu lwalatha idkumkhethi - kufuneka wongeze aria-controlsuphawu lwento yolawulo, equlathe idinto eqengqelekayo. Izifundi zesikrini zanamhlanje kunye neetekhnoloji ezincedisayo ezifanayo zisebenzisa olu phawu ukunika abasebenzisi iindlela ezimfutshane ukuya ngqo kwinto egobekayo ngokwayo.

Qaphela ukuba uphumezo lwangoku lweBootstrap aluquki udibaniso lwebhodi yezitshixo ezahlukeneyo ezichazwe kwi- WAI-ARIA yokuBhalisa iipatheni 1.1 ipateni yeaccordion - kuya kufuneka uzibandakanye ngokwakho kunye neJavaScript yesiko.

Ukusetyenziswa

Iplagin yokuwa isebenzisa iiklasi ezimbalwa ukuphatha ukuphakamisa okunzima:

.collapseifihla umxholo
.collapse.showibonisa umxholo
.collapsingyongezwa xa inguqu iqala, kwaye isuswe xa igqibile

Ezi klasi zinokufumaneka kwi _transitions.scss.

Ngeempawu zedatha

Yongeza nje data-toggle="collapse"kunye no data-target-a kwisiqalelo ukwabela ngokuzenzekelayo ulawulo lwento enye okanye ezininzi eziqengqelekayo. Uphawu data-targetloyelelwano lwamkela umkhethi we-CSS ukuze kufakwe ukutshitshiswa. Qinisekisa ukuba wongeza iklasi collapsekwinto eqengqelekayo. Ukuba ungathanda ukuba ivuleke ngokungagqibekanga, yongeza udidi olongezelelweyo show.

Ukongeza ulawulo lweqela elifana ne-accordion kwindawo egotywayo, yongeza uphawu loyelelwano lwedatha data-parent="#selector". Jonga kwidemo ukuze ubone oku kusebenza.

NgeJavaScript

Vula ngesandla nge:

$('.collapse').collapse()

Iinketho

Iinketho zinokugqithiswa ngeempawu zedatha okanye iJavaScript. Kuphawu lwedatha, faka igama lokhetho ku data-, njengakwi data-parent="".

Igama	Uhlobo	Ukuhlala kukho	Inkcazo
umzali	umkhethi \| jQuery into \| Into ye-DOM	bubuxoki	Ukuba umzali unikiwe, ke zonke izinto eziqengqelekayo phantsi komzali ochaziweyo ziya kuvalwa xa le nto iqengqelekayo iboniswa. (efana nokuziphatha kwe-accordion yendabuko - oku kuxhomekeke `card`kwiklasi). Uphawu kufuneka lubekwe kwindawo ekujoliswe kuyo egotywayo.

Iindlela

Iindlela ze-Asynchronous kunye notshintsho

Zonke iindlela ze-API zi -asynchronous kwaye ziqala utshintsho . Babuyela kumnxeba ngokukhawuleza nje ukuba utshintsho luqalisiwe kodwa ngaphambi kokuba luphele . Ukongeza, ukufowunelwa kwendlela kwicandelo lenguquko kuya kuhoywa .

Jonga uxwebhu lwethu lweJavaScript ngolwazi olungakumbi .

`.collapse(options)`

Yenza umxholo wakho ube yinto eqengqelekayo. Yamkela iinketho ozikhethelayo object.

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

`.collapse('toggle')`

Iguqulela into eqengqelekayo ukuze iboniswe okanye ifihliwe. Ibuyisela kumnxeba phambi kokuba into eqengqelekayo iboniswe okanye ifihliwe (okt phambi kokuba isiganeko shown.bs.collapseokanye hidden.bs.collapseisiganeko senzeke).

`.collapse('show')`

Ibonisa into eqengqelekayo. Ibuyisela kumnxeba phambi kokuba into eqengqelekayo iboniswe (okt phambi kokuba shown.bs.collapseisiganeko senzeke).

`.collapse('hide')`

Ifihla into eqengqelekayo. Ibuyisela kumnxebi phambi kokuba into eqengqelekayo ifihlwe (okt phambi kokuba hidden.bs.collapseisiganeko senzeke).

`.collapse('dispose')`

Itshabalalisa ukuwa kwento.

Iziganeko

Iklasi yokuwa yeBootstrap iveza iminyhadala embalwa yokuhuka ekusebenzeni kokuwa.

Uhlobo loMnyhadala	Inkcazo
bonisa.bs.collapse	Esi siganeko sivutha ngokukhawuleza xa `show`kubizwa indlela yomzekelo.
ibonisiwe.bs.collapse	Esi siganeko sigxothwa xa into yokudilika yenziwe yabonakala kumsebenzisi (iya kulinda iinguqu zeCSS ukuba zigqibe).
fihla.bs.coqa	Esi siganeko sigxothwa ngokukhawuleza xa `hide`indlela sele ibizwa.
efihliweyo.bs.ukudilika	Esi siganeko sigxothwa xa into yokudilika ifihliwe kumsebenzisi (iya kulinda iinguqu zeCSS ukuba zigqibe).

$('#myCollapsible').on('hidden.bs.collapse', function () {
  // do something...
})
