Te kawe i te tikanga ki nga hangarau awhina

Ko te whakamahi i te tae ki te taapiri i te tikanga he tohu tirohanga noa iho, kaore e tukuna ki nga kaiwhakamahi hangarau awhina - penei i nga kaipanui mata. Me mohio kei te kitea nga korero e tohuhia ana e te tae mai i te ihirangi ake (hei tauira, te tuhinga ka kitea), ka whakaurua ranei ma etahi atu huarahi, penei i etahi atu tuhinga huna ki te .visually-hiddenakomanga.

Monokia te takai kuputuhi

Ki te kore koe e pirangi kia takai te kupu patene, ka taea e koe te taapiri i te .text-nowrapkaraehe ki te paatene. I roto i te Sass, ka taea e koe te tautuhi $btn-white-space: nowrapki te whakakore i te takai kuputuhi mo ia paatene.

Nga tohu paatene

Kua .btnhoahoatia nga karaehe hei whakamahi me te <button>huānga. Heoi, ka taea hoki e koe te whakamahi i enei karaehe ki runga , ki nga huānga <a>ranei <input>(ahakoa he rereke te ahua o etahi kaitirotiro).

Ina whakamahi i nga karaehe patene i runga i <a>nga huānga e whakamahia ana ki te whakaoho i te mahi-a-wharangi (penei i te tiango ihirangi), kaua ki te hono ki nga wharangi hou, ki nga waahanga ranei o te wharangi o naianei, me hoatu enei hononga ki te role="button"kawe tika i o raatau kaupapa ki nga hangarau awhina penei i te kaipānui mata.

Hononga

<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">

Patene Whakahuahua

Kei te hiahia te paatene, engari ehara i nga tae papamuri nui e mauria mai ana? Whakakapihia nga karaehe whakarereke taunoa me nga .btn-outline-*mea hei tango i nga whakaahua papamuri me nga tae katoa i runga i tetahi paatene.

<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>

Ko etahi o nga momo patene e whakamahi ana i te tae o mua ahua marama, a me whakamahi i runga i te papamuri pouri kia pai ai te rereke.

Rahi

Kei te pirangi koe ki nga paatene nui, iti ake ranei? Tāpirihia mo etahi atu rahinga .btn-lgranei ..btn-sm

<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>

<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>

Te ahua haua

Kia hohekore nga paatene ma te taapiri i te disabledhuanga boolean ki tetahi <button>huānga. Kua tonohia nga patene monokia pointer-events: noneki te aukati i te whakaparo me nga ahuatanga hohe kia kore e puta.

<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>

<a>He rereke te ahua o nga patene monoa e whakamahi ana i te huānga:

<a>s kore e tautoko i te disabledhuanga, no reira me tapiri e koe te .disabledkaraehe kia kore ai e kitea te haua.
Ko etahi o nga momo ahua pai mo nga ra kei te heke mai hei whakakore i nga mea katoa pointer-eventsi runga i nga paatene punga.
Ko nga paatene kua monokia <a>me whakauru tearia-disabled="true" huanga hei tohu i te ahua o te huānga ki nga hangarau awhina.
Ko nga paatene kua monokia <a> kaua e whakauru i te hrefhuanga.

Hononga tuatahi Hononga

<a class="btn btn-primary btn-lg disabled" role="button" aria-disabled="true">Primary link</a>
<a class="btn btn-secondary btn-lg disabled" role="button" aria-disabled="true">Link</a>

hono hono taumahinga whakatupato

Hei hipoki i nga keehi me pupuri koe i te hrefhuanga i runga i te hononga haua, ka .disabledwhakamahi te karaehe pointer-events: noneki te ngana ki te whakakore i te taumahinga hono a <a>s. Kia mahara ko tenei taonga CSS kaore ano kia paerewahia mo HTML, engari kei te tautoko nga kaitirotiro hou katoa. I tua atu, ahakoa i roto i nga kaitirotiro e tautoko pointer-events: noneana, kaore e pa ana te whakatere papapātuhi, ko te tikanga ka taea tonu e nga kaiwhakamahi papapātuhi me nga kaiwhakamahi o nga hangarau awhina te whakahohe i enei hononga. Na kia noho haumaru, hei taapiri atu ki te aria-disabled="true", whakauruhia he tabindex="-1"huanga ki runga i enei hononga kia kore ai ratou e whiwhi arotahi papapātuhi, me te whakamahi i te JavaScript ritenga ki te whakakore i o raatau mahi.

Hononga tuatahi Hononga

<a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>

Patene poraka

Waihangahia he puranga urupare o te whanui-katoa, "patene paraka" pera i era i Bootstrap 4 me te whakakotahitanga o a maatau taputapu whakaatu me te waatea. Ma te whakamahi i nga taputapu hei utu mo nga karaehe patene, ka nui ake te mana whakahaere mo te mokowā, te tirohanga, me nga whanonga aro.

<div class="d-grid gap-2">
  <button class="btn btn-primary" type="button">Button</button>
  <button class="btn btn-primary" type="button">Button</button>
</div>

I konei ka waihangahia e matou he rereketanga urupare, ka timata mai i nga patene poutū tae noa ki te mdwaahi pakaru, ka .d-md-blockwhakakapi i te .d-gridakomanga, na reira ka whakakorehia te gap-2whaipainga. Whakanuia te rahi o to kaitirotiro kia kitea e huri ana.

<div class="d-grid gap-2 d-md-block">
  <button class="btn btn-primary" type="button">Button</button>
  <button class="btn btn-primary" type="button">Button</button>
</div>

Ka taea e koe te whakatika i te whanui o o paatene paraka me nga karaehe whanui poupae matiti. Hei tauira, mo te hawhe-whanui "patene poraka", whakamahia .col-6. Whakawaenga whakapae ki te .mx-auto, rawa.

<div class="d-grid gap-2 col-6 mx-auto">
  <button class="btn btn-primary" type="button">Button</button>
  <button class="btn btn-primary" type="button">Button</button>
</div>

Ka taea te whakamahi i etahi atu taputapu hei whakatika i te tirohanga o nga paatene ina whakapae. I konei kua tangohia e matou ta matou tauira urupare o mua me te taapiri i etahi taputapu ngawari me tetahi taputapu tawhē i runga i te paatene ki te whakatika tika i nga paatene ka kore e tapae.

<div class="d-grid gap-2 d-md-flex justify-content-md-end">
  <button class="btn btn-primary me-md-2" type="button">Button</button>
  <button class="btn btn-primary" type="button">Button</button>
</div>

Pātene monomai

Ma te paatene mono ka taea e koe te hanga i nga paatene takahuri ngawari.

Ki te titiro, he rite enei patene takahuri ki nga paatene takahuri pouakataki . Heoi, he rereke te kawe mai e nga hangarau awhina: ka panuihia nga takahuri pouakataki e nga kaipanui mata he "tirohia"/"kaore i takina" (i te mea, ahakoa te ahua, he pouakataki tonu), engari ko enei paatene takahuri ka panuitia hei “pātene”/“pātene pēhi”. Ko te whiriwhiri i waenga i enei huarahi e rua ka whakawhirinaki ki te momo takahuri e hangaia ana e koe, a mena ka whai whakaaro te takahuri ki nga kaiwhakamahi ina panuitia hei pouakataki, hei paatene tuuturu ranei.

Takahuri āhua

Tāpirihia data-bs-toggle="button"hei takahuri i te activeahua o te paatene. Mēnā kei te takahuri i mua i te paatene, me taapiri a ringa koe i te .activeakomanga me aria-pressed="true" te whakarite kia tika te kawe ki nga hangarau awhina.

<button type="button" class="btn btn-primary" data-bs-toggle="button" autocomplete="off">Toggle button</button>
<button type="button" class="btn btn-primary active" data-bs-toggle="button" autocomplete="off" aria-pressed="true">Active toggle button</button>
<button type="button" class="btn btn-primary" disabled data-bs-toggle="button" autocomplete="off">Disabled toggle button</button>

Takahuri hono Hono takahuri hohe Kua monoa te hono takahuri

<a href="#" class="btn btn-primary" role="button" data-bs-toggle="button">Toggle link</a>
<a href="#" class="btn btn-primary active" role="button" data-bs-toggle="button" aria-pressed="true">Active toggle link</a>
<a class="btn btn-primary disabled" aria-disabled="true" role="button" data-bs-toggle="button">Disabled toggle link</a>

Nga tikanga

Ka taea e koe te hanga i tetahi tauira paatene me te kaihanga paatene, hei tauira:

var button = document.getElementById('myButton')
var bsButton = new bootstrap.Button(button)

Tikanga	Whakaahuatanga
`toggle`	Ka takahuri te ahua pana. Ka hoatu ki te paatene te ahua kua whakahohehia.
`dispose`	Ka whakakore i te paatene o te huānga. (Tangohia ai nga raraunga rongoa i te huānga DOM)
`getInstance`	Tikanga pateko e taea ai e koe te tiki i te tauira paatene e hono ana ki tetahi huānga DOM, ka taea e koe te whakamahi penei:`bootstrap.Button.getInstance(element)`
`getOrCreateInstance`	Aratuka pateko e whakahoki mai ana i tetahi tauira patene e hono ana ki tetahi huānga DOM, ka hanga ranei i tetahi mea hou mena kaore i arawhitia. Ka taea e koe te whakamahi penei:`bootstrap.Button.getOrCreateInstance(element)`

Hei tauira, ki te takahuri i nga paatene katoa

var buttons = document.querySelectorAll('.btn')
buttons.forEach(function (button) {
  var button = new bootstrap.Button(button)
  button.toggle()
})
