Toggle qhov pom ntawm cov ntsiab lus thoob plaws koj qhov project nrog ob peb chav kawm thiab peb cov JavaScript plugins.

Nws ua haujlwm li cas

Lub cev qhuav dej JavaScript plugin yog siv los qhia thiab zais cov ntsiab lus. Cov nyees khawm lossis cov thauj tog rau nkoj yog siv los ua cov cim uas tau teeb tsa rau cov ntsiab lus tshwj xeeb uas koj hloov pauv. Collapsing ib lub caij yuav animate heightlos ntawm nws cov nqi tam sim no rau 0. Muab CSS ua haujlwm li cas rau cov animations, koj siv tsis tau paddingntawm ib lub .collapsecaij. Hloov chaw, siv cov chav kawm ua ib qho kev nthuav dav ntawm cov ntaub qhwv.

Cov nyhuv animation ntawm cov khoom siv no yog nyob ntawm cov prefers-reduced-motionlus nug xov xwm. Saib qhov txo qis ntawm peb cov ntaub ntawv nkag mus tau .

Piv txwv

Nyem rau cov nyees khawm hauv qab no los qhia thiab zais lwm lub ntsiab lus ntawm kev hloov hauv chav kawm:

  • .collapsezais cov ntsiab lus
  • .collapsingyog siv thaum lub sij hawm hloov
  • .collapse.showqhia cov ntsiab lus

Koj tuaj yeem siv qhov txuas nrog tus hrefcwj pwm, lossis khawm nrog tus data-targetcwj pwm. Hauv ob qho xwm txheej, qhov data-toggle="collapse"yuav tsum tau ua.

Kev siv tau

Nco ntsoov ntxiv aria-expandedrau lub caij tswj. Tus cwj pwm no qhia meej meej txog lub xeev tam sim no ntawm lub caij sib tsoo khi rau kev tswj kom tshuaj xyuas cov neeg nyeem thiab cov thev naus laus zis zoo sib xws. Yog tias lub caij collapsible raug kaw los ntawm lub neej ntawd, tus cwj pwm ntawm cov khoom tswj yuav tsum muaj tus nqi ntawm aria-expanded="false". Yog tias koj tau teeb tsa lub caij collapsible kom qhib los ntawm lub neej ntawd siv cov showchav kawm, teem caij aria-expanded="true"rau kev tswj hwm. Lub plugin yuav cia li toggle tus cwj pwm no ntawm kev tswj xyuas raws li seb puas tau qhib lossis kaw (ntawm JavaScript, lossis vim tias tus neeg siv tau ua rau lwm qhov kev tswj hwm tseem khi rau tib lub caij sib tsoo). Yog hais tias tus tswj hwm lub ntsiab HTML tsis yog khawm (piv txwv li, ib qho <a>lossis <div>), tus cwj pwmrole="button"yuav tsum tau ntxiv rau lub caij.

Yog tias koj lub ntsiab tswj yog tsom rau ib qho kev sib tsoo - piv txwv li tus data-targetcwj pwm yog taw tes rau tus idxaiv - koj yuav tsum ntxiv tus aria-controlscwj pwm rau cov khoom tswj, uas muaj cov idkhoom sib tsoo. Cov ntawv nyeem niaj hnub no thiab cov thev naus laus zis zoo sib xws ua rau siv cov cwj pwm no los muab cov neeg siv nrog cov shortcuts ntxiv rau kev taw qhia ncaj qha rau lub caij sib tsoo nws tus kheej.

Nco ntsoov tias Bootstrap qhov kev siv tam sim no tsis suav nrog ntau yam kev sib cuam tshuam ntawm cov keyboard tau piav qhia hauv WAI-ARIA Authoring Practices 1.1 accordion qauv - koj yuav tsum suav nrog koj tus kheej nrog kev cai JavaScript.

Kev siv

Lub cev qhuav dej siv ob peb chav kawm los daws qhov hnyav nqa:

  • .collapsezais cov ntsiab lus
  • .collapse.showqhia cov ntsiab lus
  • .collapsingntxiv thaum qhov kev hloov pauv pib, thiab tshem tawm thaum nws tiav

Cov chav kawm no tuaj yeem pom hauv _transitions.scss.

Los ntawm cov ntaub ntawv attributes

Tsuas yog ntxiv data-toggle="collapse"thiab ib qho data-targetrau lub caij kom tau txais kev tswj hwm ntawm ib lossis ntau lub ntsiab lus collapsible. Tus data-targetcwj pwm lees txais CSS xaiv los siv lub cev qhuav dej rau. Nco ntsoov ntxiv cov chav kawm collapserau lub caij collapsible. Yog tias koj xav kom nws qhib lub neej ntawd, ntxiv cov chav kawm ntxiv show.

Txhawm rau ntxiv accordion-zoo li pab pawg tswj hwm rau thaj tsam collapsible, ntxiv cov ntaub ntawv tus cwj pwm data-parent="#selector". Xa mus rau qhov demo kom pom qhov no hauv kev nqis tes ua.

Ntawm JavaScript

Qhib manually nrog:

$('.collapse').collapse()

Kev xaiv

Cov kev xaiv tuaj yeem dhau los ntawm cov ntaub ntawv tus cwj pwm lossis JavaScript. Rau cov ntaub ntawv tus cwj pwm, ntxiv rau qhov kev xaiv npe rau data-, xws li hauv data-parent="".

Lub npe Hom Default Kev piav qhia
niam txiv xaiv | jQuery khoom | DOM Element cuav Yog tias niam txiv muab, ces tag nrho cov ntsiab lus collapsible nyob rau hauv cov niam txiv uas tau teev tseg yuav raug kaw thaum cov khoom sib tsoo no tshwm sim. (zoo ib yam li kev coj cwj pwm accordion - qhov no yog nyob ntawm cardchav kawm). Tus cwj pwm yuav tsum tau teem rau ntawm lub hom phiaj collapsible.
toggle boolean muaj tseeb Toggles lub caij collapsible ntawm invocation

Cov txheej txheem

Asynchronous txoj kev thiab kev hloov

Txhua txoj kev API yog asynchronous thiab pib hloov pauv . Lawv rov qab mus rau tus neeg hu xov tooj sai li sai tau thaum qhov kev hloov pauv pib tab sis ua ntej nws xaus . Tsis tas li ntawd, ib txoj kev hu rau ib qho kev hloov pauv yuav raug tsis quav ntsej .

Saib peb cov ntaub ntawv JavaScript kom paub ntau ntxiv .

.collapse(options)

Activates koj cov ntsiab lus raws li ib tug collapsible caij. Txais ib qho kev xaiv xaiv object.

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

Destroys ib lub caij poob.

Cov xwm txheej

Bootstrap's collapse class exposes ob peb txheej xwm rau hooking mus rau hauv vau functionality.
