Tiango

Takahurihia te whakakitenga o te ihirangi puta noa i to kaupapa me etahi karaehe me a maatau taputapu JavaScript.

Me pehea te mahi

Ka whakamahia te mono JavaScript tiango hei whakaatu me te huna i nga ihirangi. Ka whakamahia nga patene, punga ranei hei keu ka mapi ki nga huānga motuhake ka takahurihia e koe. Ma te tiango i tetahi huānga ka whakakorikori heighti te uara o naianei ki 0. Me pehea te whakahaere a CSS i nga pakiwaituhi, kaore e taea e koe te whakamahi paddingi runga i tetahi .collapsehuānga. Engari, whakamahia te akomanga hei huānga takai motuhake.

Tauira

Patohia nga paatene i raro nei hei whakaatu me te huna i tetahi atu huānga ma nga huringa akomanga:

  • .collapsehuna ihirangi
  • .collapsingka whakamahia i nga wa whakawhiti
  • .collapse.showwhakaatu ihirangi

Ka taea e koe te whakamahi i te hono me te hrefhuanga, te paatene ranei me te data-targethuanga. I roto i nga take e rua, data-toggle="collapse"e hiahiatia ana.

Te urunga

Me tino taapiri atu aria-expandedki te huānga mana. Ko tenei huanga e whakaatu marama ana i te ahuatanga o naianei o te huānga tiango e herea ana ki te mana ki nga kaipanui mata me nga hangarau awhina rite. Ki te katia te huānga tiango ma te taunoa, me whai uara o te huanga o te huānga mana aria-expanded="false". Mena kua tautuhia e koe te huānga tiango kia tuwhera taunoa ma te whakamahi i te showkaraehe, tohua aria-expanded="true"ki te mana. Ko te mono ka huri aunoa i tenei huanga i runga i te mana i runga i te mea kua whakatuwherahia, kua kati ranei te huānga tiango (ma te JavaScript, na te mea i whakaoho te kaiwhakamahi i tetahi atu huānga mana e herea ana ki taua huānga tiango). Mena ehara te huānga HTML o te mana whakahaere i te paatene (hei tauira, he, he <a>ranei <div>), te huangarole="button"me taapiri atu ki te huānga.

Mēnā e aro ana tō huānga mana ki tētahi huānga tiango kotahi – arā data-target, e tohu ana te huanga ki tētahi idkaikōwhiri – me tāpiri koe i te aria-controlshuanga ki te huānga mana, kei roto te ido te huānga tiango. Ka whakamahia e nga kaipanui mata hou me nga hangarau awhina rite tenei huanga ki te whakarato ki nga kaiwhakamahi etahi atu pokatata ki te whakatere tika ki te huānga tiango ake.

Kia mahara ko te whakatinanatanga o naianei a Bootstrap kaore e kapi i nga momo taunekeneke papapātuhi e whakaahuatia ana i roto i te tauira akoriona Wai-ARIA Authoring Practices 1.1 - me whakauru e koe enei ki te JavaScript ritenga.

Whakamahinga

Ka whakamahia e te mono tiango etahi karaehe hei hapai i te hiki taumaha:

  • .collapseka huna i te ihirangi
  • .collapse.showwhakaatu te ihirangi
  • .collapsingka taapirihia ina timata te whakawhiti, ka tangohia ina mutu

Ka kitea enei akomanga i roto i _transitions.scss.

Ma nga huanga raraunga

Taapiri noa data-toggle="collapse"me te data-targeta ki te huānga hei tautapa aunoa i te mana o tetahi, neke atu ranei nga huānga tiango. Ka data-targetwhakaaetia e te huanga he kaikowhiri CSS hei hoatu i te tiango ki. Me tino taapiri te karaehe collapseki te huānga tiango. Mena kei te pirangi koe kia tuwhera taunoa, taapirihia te akomanga taapiri show.

Hei taapiri i te whakahaere roopu rite-akordion ki tetahi waahi tiango, taapirihia te huanga raraunga data-parent="#selector". Tirohia te demo kia kite i tenei mahi.

Ma te JavaScript

Whakahohe ā-ringa ki:

$('.collapse').collapse()

Kōwhiringa

Ko nga whiringa ka taea te tuku ma nga huanga raraunga, JavaScript ranei. Mo nga huanga raraunga, apitihia te ingoa whiringa ki data-, penei i te data-parent="".

Ingoa Momo Taunoa Whakaahuatanga
matua kaiwhiriwhiri | ahanoa jQuery | huānga DOM teka Mena ka tukuna he matua, ka katia nga huānga tiango katoa i raro i te matua kua tohua ina whakaatuhia mai tenei mea tiango. (he rite ki te whanonga accordion tuku iho - ka whakawhirinaki tenei ki te cardkaraehe). Me whakanoho te huanga ki runga i te waahi ka taea te tiango.
takahuri boolean pono Ka takahuri i te huānga tiango i runga i te inoi

Nga tikanga

Nga tikanga tukutahi me nga whakawhitinga

Ko nga tikanga API katoa he tukutahi ka timata te whakawhiti . Ka hoki mai ano ki te kaikaranga ina timata te whakawhiti engari i mua i te mutunga . I tua atu, ka warewarehia te karanga tikanga mo tetahi waahanga whakawhiti .

Tirohia ta maatau tuhinga JavaScript mo etahi atu korero.

.collapse(options)

Ka whakahohe i to ihirangi hei huānga tiango. Ka whakaae ki nga whiringa whiriwhiri object.

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

.collapse('toggle')

Ka takahuri i tetahi huānga tiango hei whakaatu, huna ranei. Ka hoki ki te kaiwaea i mua i te whakaaturanga, huna ranei o te huānga tiango (arā, i mua i te puta o shown.bs.collapsete hidden.bs.collapsetakahanga).

.collapse('show')

He whakaatu huānga tiango. Ka hoki ki te kaiwaea i mua i te whakaaturanga o te huānga tiango (arā i mua i te shown.bs.collapseputa o te takahanga).

.collapse('hide')

Hunaia he huānga tiango. Ka hoki ki te kaiwaea i mua i te hunanga o te huānga tiango (arā i mua i te hidden.bs.collapseputa o te takahanga).

.collapse('dispose')

Ka whakangaro i te tiango o te huānga.

Nga huihuinga

Ko te karaehe tiango a Bootstrap e whakaatu ana i etahi huihuinga mo te hono ki te mahi tiango.

Momo Takahanga Whakaahuatanga
show.bs.collapse Ka pupuhi tenei takahanga ina ka showkarangahia te aratuka tauira.
whakaaturia.bs.collapse Ka puhia tenei takahanga ina kitea he huānga tiango ki te kaiwhakamahi (ka tatari kia oti nga whakawhitinga CSS).
huna.bs.collapse Ka pupuhihia tenei kaupapa i te wa hidei kiia ai te tikanga.
huna.bs.collapse Ka puhia tenei takahanga ina hunahia he huānga tiango mai i te kaiwhakamahi (ka tatari kia oti nga whakawhitinga CSS). 
$('#myCollapsible').on('hidden.bs.collapse', function () {
  // do something…
})
