Nco ntsoov ntxiv aria-expanded
rau 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 show
chav 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 ua rau lwm qhov kev tswj hwm kuj tau 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-target
cwj pwm yog taw tes rau tus id
xaiv - koj yuav tsum ntxiv tus aria-controls
cwj pwm rau cov khoom tswj, uas muaj cov id
khoom 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.
Lub cev qhuav dej siv ob peb chav kawm los daws qhov hnyav nqa:
.collapse
zais cov ntsiab lus.collapse.show
qhia cov ntsiab lus.collapsing
ntxiv thaum qhov kev hloov pauv pib, thiab tshem tawm thaum nws tiav
Cov chav kawm no tuaj yeem pom hauv _transitions.scss
.
Tsuas yog ntxiv data-toggle="collapse"
thiab ib qho data-target
rau lub caij kom tau txais kev tswj hwm ntawm ib lossis ntau lub ntsiab lus collapsible. Tus data-target
cwj pwm lees txais CSS xaiv los siv lub cev qhuav dej rau. Nco ntsoov ntxiv cov chav kawm collapse
rau 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.
Qhib manually nrog:
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-
