Pehea e hana ai

Hoʻohana ʻia ka plugin JavaScript collapse e hōʻike a hūnā i ka ʻike. Hoʻohana ʻia nā pihi a i ʻole nā ​​heleuma e like me nā mea hoʻomaka i palapala ʻia i nā mea kikoʻī āu e hoʻololi ai. ʻO ka hoʻohiolo ʻana i kahi mea e hoʻolalelale i ka heightmai kona waiwai i kēia manawa i 0. Hāʻawi ʻia pehea e mālama ai ʻo CSS i nā animation, ʻaʻole hiki iā ʻoe ke hoʻohana paddingma kahi .collapsemea. Akā, e hoʻohana i ka papa ma ke ʻano he mea hoʻopili kūʻokoʻa.

Laʻana

Kaomi i nā pihi ma lalo nei e hōʻike a hūnā i kekahi mea ma o nā hoʻololi papa:

• .collapsehuna mea
• .collapsinghoʻohana ʻia i ka wā hoʻololi
• .collapse.showhōʻike maʻiʻo

ʻO ka maʻamau, manaʻo mākou e hoʻohana i kahi pihi me ke data-bs-targetʻano. ʻOiai ʻaʻole ʻōlelo ʻia mai kahi manaʻo semantic, hiki iā ʻoe ke hoʻohana i kahi loulou me ke hrefʻano (a me kahi role="button"). I nā hihia ʻelua, data-bs-toggle="collapse"pono ka mea.

<p>
  <a class="btn btn-primary" data-bs-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
    Link with href
  </a>
  <button class="btn btn-primary" type="button" data-bs-toggle="collapse" data-bs-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
    Button with data-bs-target
  </button>
</p>
<div class="collapse" id="collapseExample">
  <div class="card card-body">
    Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.
  </div>
</div>

Kaupae

Kākoʻo pū ka plugin collapse i ka hāʻule ʻana. E hoʻohui i ka .collapse-horizontalpapa hoʻololi e hoʻololi i ka widthma kahi o heighta hoʻonoho i kahi widthma ka mea keiki koke. E ʻoluʻolu e kākau i kāu Sass maʻamau, e hoʻohana i nā ʻano inline, a i ʻole e hoʻohana i kā mākou mau pono ākea .

Hiki ke komo

E hōʻoia e hoʻohui aria-expandedi ka mea hoʻomalu. Hōʻike maopopo kēia ʻano i ke kūlana o kēia manawa o ka mea hiki ke hoʻopili ʻia i ka mana i ka nānā ʻana i nā mea heluhelu a me nā ʻenehana kōkua like. Inā pani ʻia ka mea hiki ke hoʻoheheʻe ʻia ma ke ʻano paʻamau, pono e loaʻa i ke ʻano o ka mea mana ka waiwai o aria-expanded="false". Inā ua hoʻonoho ʻoe i ka mea hiki ke hoʻoheheʻe ʻia e wehe ʻia ma ka hoʻohana ʻana i ka showpapa, e hoʻonoho aria-expanded="true"ma ka mana. E hoʻololi ʻokoʻa ka plugin i kēia ʻano ma luna o ka mana e pili ana i ka wehe ʻana a i ʻole ka pani ʻana o ka mea collapsible (ma o JavaScript, a i ʻole no ka mea hoʻohana ka mea hoʻohana i kahi mea mana ʻē aʻe i hoʻopaʻa ʻia i ka mea hiki ke collapsible). Inā ʻaʻole he pihi ka ʻelemu HTML o ka mea hoʻomalu (e laʻa, a i <a>ʻole <div>), ka ʻanorole="button"pono e hoʻohui i ka mea.

Inā e huli ana kāu mea hoʻomalu i hoʻokahi mea hiki ke hoʻoheheʻe ʻia - ʻo ia hoʻi ke data-bs-targetkuhikuhi nei ka ʻano i kahi idmea koho - pono ʻoe e hoʻohui i ka aria-controlsʻano i ka mea hoʻomalu, i loaʻa ka idmea hiki ke hoʻoheheʻe ʻia. Hoʻohana ka poʻe heluhelu ʻaoʻao o kēia wā a me nā ʻenehana kōkua like i kēia ʻano e hāʻawi i nā mea hoʻohana i nā ʻaoʻao pōkole hou e hoʻokele pololei i ka mea hiki ke hoʻoheheʻe ʻia.

E hoʻomanaʻo, ʻaʻole i uhi ʻia ka hoʻokō ʻana o Bootstrap i nā pānaʻi kīwī koho like ʻole i wehewehe ʻia ma ka WAI-ARIA Authoring Practices 1.1 accordion pattern - pono ʻoe e hoʻokomo iā ʻoe iho me ka JavaScript maʻamau.

Sass

Nā mea hoʻololi

$transition-collapse:         height .35s ease;
$transition-collapse-width:   width .35s ease;

Nā papa

Hiki ke loaʻa nā papa hoʻololi hāʻule i ka scss/_transitions.scsslike ʻana o kēia mau mea ma nā ʻāpana he nui (collapse and accordion).

.collapse {
  &:not(.show) {
    display: none;
  }
}

.collapsing {
  height: 0;
  overflow: hidden;
  @include transition($transition-collapse);

  &.collapse-horizontal {
    width: 0;
    height: auto;
    @include transition($transition-collapse-width);
  }
}

Hoʻohana

Hoʻohana ka collapse plugin i kekahi mau papa e hoʻokō i ka hāpai kaumaha:

• .collapsehūnā i ka ʻike
• .collapse.showhōʻike i ka ʻike
• .collapsinghoʻohui ʻia i ka wā e hoʻomaka ai ka hoʻololi, a wehe ʻia i ka wā e pau ai

Hiki ke loaʻa kēia mau papa ma _transitions.scss.

Ma o nā hiʻohiʻona ʻikepili

Hoʻohui wale data-bs-toggle="collapse"a me kahi data-bs-targeti ka mea e hāʻawi ʻakomi i ka mana o hoʻokahi a ʻoi aku paha nā mea hiki ke collapsible. data-bs-targetʻAe ka ʻano i kahi mea koho CSS e hoʻopili ai i ka hāʻule . E hōʻoia e hoʻohui i ka papa collapsei ka mea hiki ke collapsible. Inā makemake ʻoe e wehe paʻamau, e hoʻohui i ka papa hou show.

No ka hoʻohui ʻana i ka hoʻokele hui e like me ka accordion i kahi ʻāpana collapsible, hoʻohui i ke ʻano ʻikepili data-bs-parent="#selector". E nānā i ka ʻaoʻao accordion no ka ʻike hou aku.

Ma o JavaScript

E ho'ā me ka lima me:

var collapseElementList = [].slice.call(document.querySelectorAll('.collapse'))
var collapseList = collapseElementList.map(function (collapseEl) {
  return new bootstrap.Collapse(collapseEl)
})

Nā koho

Hiki ke hāʻawi ʻia nā koho ma o nā ʻikepili a i ʻole JavaScript. No nā ʻano ʻikepili, e hoʻopili i ka inoa koho i data-bs-, e like me ka data-bs-parent="".

Nā ʻano hana

Ho'ā i kāu ʻike ma ke ʻano he mea hiki ke collapsible. ʻAe i kahi koho koho object.

Hiki iā ʻoe ke hana i kahi hiʻohiʻona hāʻule me ka mea hana, no ka laʻana:

var myCollapse = document.getElementById('myCollapse')
var bsCollapse = new bootstrap.Collapse(myCollapse, {
  toggle: false
})

Nā hanana

Hōʻike ka papa hāʻule o Bootstrap i kekahi mau hanana no ka hoʻopili ʻana i ka hana hāʻule.

var myCollapsible = document.getElementById('myCollapsible')
myCollapsible.addEventListener('hidden.bs.collapse', function () {
  // do something...
})
