Modal
Tumia programu-jalizi ya modali ya JavaScript ya Bootstrap ili kuongeza vidadisi kwenye tovuti yako kwa visanduku vyepesi, arifa za watumiaji, au maudhui maalum kabisa.
Inavyofanya kazi
Kabla ya kuanza na kijenzi cha modali cha Bootstrap, hakikisha kuwa umesoma yafuatayo kwani chaguzi zetu za menyu zimebadilika hivi majuzi.
- Moduli hujengwa kwa HTML, CSS na JavaScript. Zimewekwa juu ya kila kitu kingine kwenye hati na huondoa kusongesha kutoka
<body>
ili maudhui ya modal yasogeze badala yake. - Kubofya kwenye "mandhari" ya modal kutafunga modali kiotomatiki.
- Bootstrap inasaidia tu dirisha moja la modal kwa wakati mmoja. Miundo iliyopachikwa haitumiki kwa kuwa tunaamini kuwa matumizi mabaya ya watumiaji.
- Modals use
position: fixed
, ambayo wakati mwingine inaweza kuwa maalum kidogo juu ya utoaji wake. Inapowezekana, weka HTML yako ya modali katika nafasi ya juu ili kuepuka kuingiliwa kwa vipengele vingine. Huenda utakumbana na matatizo wakati wa kuweka kiota.modal
ndani ya kipengele kingine kisichobadilika. - Kwa mara nyingine tena, kutokana na
position: fixed
, kuna baadhi ya tahadhari za kutumia moduli kwenye vifaa vya rununu. Tazama hati zetu za usaidizi wa kivinjari kwa maelezo. - Kutokana na jinsi HTML5 inavyofafanua semantiki zake, sifa ya
autofocus
HTML haina athari katika miundo ya Bootstrap. Ili kufikia athari sawa, tumia JavaScript maalum:
var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')
myModal.addEventListener('shown.bs.modal', function () {
myInput.focus()
})
prefers-reduced-motion
hoja ya midia. Tazama
sehemu ya mwendo iliyopunguzwa ya hati zetu za ufikivu .
Endelea kusoma kwa maonyesho na miongozo ya matumizi.
Mifano
Vipengele vya modal
Hapo chini kuna mfano tuli wa modal (ikimaanisha kuwa yake position
na display
imebatilishwa). Imejumuishwa ni kichwa cha modali, mwili wa modali (inahitajika kwa padding
), na kijachini cha modali (si lazima). Tunaomba ujumuishe vichwa vya modal na vitendo vya kuondoa kila inapowezekana, au utoe hatua nyingine ya wazi ya kukataa.
<div class="modal" tabindex="-1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>

Onyesho la moja kwa moja
Geuza onyesho la modali ya kufanya kazi kwa kubofya kitufe kilicho hapa chini. Itateleza chini na kufifia kutoka juu ya ukurasa.
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>

<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
Mandhari tuli
Mandhari ya nyuma yanapowekwa kuwa tuli, modali haitafungwa wakati wa kubofya nje yake. Bofya kitufe kilicho hapa chini ili kuijaribu.
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#staticBackdrop">
Launch static backdrop modal
</button>
<!-- Modal -->
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="staticBackdropLabel">Modal title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">

<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Understood</button>
</div>
</div>
</div>
</div>
Inasogeza maudhui marefu
Miundo inapokuwa ndefu sana kwa kituo cha kutazama au kifaa cha mtumiaji, husogeza bila kutegemea ukurasa wenyewe. Jaribu onyesho hapa chini ili kuona tunamaanisha nini.
Unaweza pia kuunda modi inayoweza kusongeshwa ambayo inaruhusu kusogeza mwili wa modali kwa kuongeza .modal-dialog-scrollable
kwa .modal-dialog
.
<!-- Scrollable modal -->
<div class="modal-dialog modal-dialog-scrollable">
...
</div>
Imewekwa katikati
Ongeza .modal-dialog-centered
kwa .modal-dialog
katikati wima katikati ya modali.
<!-- Vertically centered modal -->
<div class="modal-dialog modal-dialog-centered">
...
</div>
<!-- Vertically centered scrollable modal -->
<div class="modal-dialog modal-dialog-centered modal-dialog-scrollable">
...
</div>
Vidokezo vya zana na popover
Vidokezo vya zana na popover vinaweza kuwekwa ndani ya moduli kama inahitajika. Miundo inapofungwa, vidokezo vyovyote vya zana na popover ndani pia huondolewa kiotomatiki.
<div class="modal-body">
<h5>Popover in a modal</h5>
<p>This <a href="#" role="button" class="btn btn-secondary popover-test" title="Popover title" data-bs-content="Popover body content is set in this attribute.">button</a> triggers a popover on click.</p>
<hr>
<h5>Tooltips in a modal</h5>
<p><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> have tooltips on hover.</p>
</div>
Kutumia gridi ya taifa
Tumia mfumo wa gridi ya Bootstrap ndani ya modali kwa kuweka kiota .container-fluid
ndani ya .modal-body
. Kisha, tumia madarasa ya mfumo wa gridi ya kawaida kama ungefanya popote pengine.
<div class="modal-body">
<div class="container-fluid">
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4 ms-auto">.col-md-4 .ms-auto</div>
</div>
<div class="row">
<div class="col-md-3 ms-auto">.col-md-3 .ms-auto</div>
<div class="col-md-2 ms-auto">.col-md-2 .ms-auto</div>
</div>
<div class="row">
<div class="col-md-6 ms-auto">.col-md-6 .ms-auto</div>
</div>
<div class="row">
<div class="col-sm-9">
Level 1: .col-sm-9
<div class="row">
<div class="col-8 col-sm-6">
Level 2: .col-8 .col-sm-6
</div>
<div class="col-4 col-sm-6">
Level 2: .col-4 .col-sm-6
</div>
</div>
</div>
</div>
</div>
</div>
Kutofautisha maudhui ya modal
Una rundo la vitufe ambavyo vyote huanzisha modali sawa na yaliyomo tofauti kidogo? Tumia event.relatedTarget
na sifa za HTMLdata-bs-*
ili kubadilisha maudhui ya modali kulingana na kitufe ambacho kilibofya.
Ifuatayo ni onyesho la moja kwa moja linalofuatwa na mfano wa HTML na JavaScript. Kwa habari zaidi, soma hati za matukio ya modal kwa maelezo kuhusu relatedTarget
.
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@fat">Open modal for @fat</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@getbootstrap">Open modal for @getbootstrap</button>
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">

<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">

<div class="mb-3">
<label for="recipient-name" class="col-form-label">Recipient:</label>
<input type="text" class="form-control" id="recipient-name">

</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Send message</button>
</div>
</div>
</div>
</div>
var exampleModal = document.getElementById('exampleModal')
exampleModal.addEventListener('show.bs.modal', function (event) {
// Button that triggered the modal
var button = event.relatedTarget
// Extract info from data-bs-* attributes
var recipient = button.getAttribute('data-bs-whatever')
// If necessary, you could initiate an AJAX request here
// and then do the updating in a callback.
//
// Update the modal's content.
var modalTitle = exampleModal.querySelector('.modal-title')
var modalBodyInput = exampleModal.querySelector('.modal-body input')
modalTitle.textContent = 'New message to ' + recipient
modalBodyInput.value = recipient
})
Geuza kati ya moduli
Geuza kati ya moduli nyingi kwa uwekaji wa busara wa data-bs-target
na data-bs-toggle
sifa. Kwa mfano, unaweza kugeuza modali ya kuweka upya nenosiri kutoka ndani ya ishara ambayo tayari imefunguliwa katika modali. Tafadhali kumbuka miundo mingi haiwezi kufunguliwa kwa wakati mmoja -njia hii hugeuza tu kati ya moduli mbili tofauti.
<div class="modal fade" id="exampleModalToggle" aria-hidden="true" aria-labelledby="exampleModalToggleLabel" tabindex="-1">
<div class="modal-dialog modal-dialog-centered">
<div class="modal-content">
<div class="modal-header">

<a class="btn btn-primary" data-bs-toggle="modal" href="#exampleModalToggle" role="button">Open first modal</a>
Badilisha uhuishaji
Tofauti $modal-fade-transform
huamua hali ya mageuzi ya .modal-dialog
kabla ya uhuishaji wa modali kufifia, $modal-show-transform
kigezo huamua ubadilishaji wa .modal-dialog
mwisho wa uhuishaji wa modal fade-in.
Ikiwa unataka kwa mfano uhuishaji wa kukuza, unaweza kuweka $modal-fade-transform: scale(.8)
.
Ondoa uhuishaji
Kwa moduli ambazo zinaonekana tu badala ya kufifia ili kutazamwa, ondoa .fade
darasa kutoka kwa lebo yako ya modal.
<div class="modal" tabindex="-1" aria-labelledby="..." aria-hidden="true">
...
</div>
Urefu wenye nguvu
Ikiwa urefu wa modali hubadilika wakati umefunguliwa, unapaswa kupiga simu myModal.handleUpdate()
ili kurekebisha nafasi ya modali ikiwa upau wa kusogeza utatokea.
Ufikivu
Hakikisha umeongeza aria-labelledby="..."
, ukirejelea kichwa cha modali, kwa .modal
. Zaidi ya hayo, unaweza kutoa maelezo ya mazungumzo yako ya modal na aria-describedby
on .modal
. Kumbuka kuwa huhitaji kuongeza role="dialog"
kwa kuwa tayari tunaiongeza kupitia JavaScript.
Inapachika video za YouTube
Kupachika video za YouTube katika miundo kunahitaji JavaScript ya ziada si kwenye Bootstrap ili kukomesha uchezaji kiotomatiki na zaidi. Tazama chapisho hili muhimu la Stack Overflow kwa maelezo zaidi.
Ukubwa wa hiari
Moduli zina saizi tatu za hiari, zinapatikana kupitia madarasa ya kurekebisha kuwekwa kwenye .modal-dialog
. Saizi hizi huingia katika sehemu fulani za kukatika ili kuepuka pau za kusogeza zilizo mlalo kwenye lango finyu za kutazama.
Ukubwa | Darasa | Modal max-upana |
---|---|---|
Ndogo | .modal-sm |
300px |
Chaguomsingi | Hakuna | 500px |
Kubwa | .modal-lg |

Matumizi
Programu-jalizi ya modal hugeuza maudhui yako yaliyofichwa inapohitajika, kupitia sifa za data au JavaScript. Pia hubatilisha tabia chaguo-msingi ya kusogeza na kuzalisha a .modal-backdrop
kutoa eneo la kubofya kwa ajili ya kuondoa miundo iliyoonyeshwa unapobofya nje ya modali.
Kupitia sifa za data
Washa modali bila kuandika JavaScript. Weka data-bs-toggle="modal"
kwenye kipengele cha kidhibiti, kama kitufe, pamoja na data-bs-target="#foo"
au href="#foo"
kulenga modi mahususi ya kugeuza.
<button type="button" data-bs-toggle="modal" data-bs-target="#myModal">Launch modal</button>
Kupitia JavaScript
Unda modali na safu moja ya JavaScript:
var myModal = new bootstrap.Modal(document.getElementById('myModal'), options)
Chaguo
Chaguzi zinaweza kupitishwa kupitia sifa za data au JavaScript. Kwa sifa za data, ongeza jina la chaguo kwa data-bs-
, kama katika data-bs-backdrop=""
.
Jina | Aina | Chaguomsingi | Maelezo |
---|---|---|---|
backdrop |
boolean au kamba'static' |
true |
Inajumuisha kipengele cha mandharinyuma ya modal. Vinginevyo, bainisha static kwa mandhari ambayo haifungi muundo wa kubofya. |
keyboard |
boolean | true |
Hufunga modali wakati kitufe cha Escape kinapobozwa |
focus |
boolean | true |
Huweka mkazo kwenye modali inapoanzishwa. |
Mbinu
Njia za Asynchronous na mabadiliko
Njia zote za API ni za asynchronous na zinaanzisha mpito . Wanarudi kwa mpigaji mara tu mpito unapoanza lakini kabla haujaisha . Kwa kuongeza, simu ya mbinu kwenye sehemu ya mpito itapuuzwa .
Kupitisha chaguzi
Huwasha maudhui yako kama modali. Inakubali chaguo za hiari object
.
var myModal = new bootstrap.Modal(document.getElementById('myModal'), {
keyboard: false
})
kugeuza
Hugeuza modali mwenyewe. Hurejesha kwa mpigaji simu kabla modali haijaonyeshwa au kufichwa (yaani kabla ya tukio shown.bs.modal
au hidden.bs.modal
tukio).
myModal.toggle()
onyesha
Hufungua moduli mwenyewe. Hurejesha kwa mpigaji simu kabla modali haijaonyeshwa (yaani kabla ya shown.bs.modal
tukio kutokea).
myModal.show()
Pia, unaweza kupitisha kipengele cha DOM kama hoja ambayo inaweza kupokelewa katika matukio ya modal (kama relatedTarget
mali).
var modalToggle = document.getElementById('toggleMyModal') // relatedTarget
myModal.show(modalToggle)
kujificha
Huficha modali mwenyewe. Hurejesha kwa mpigaji simu kabla modali haijafichwa (yaani kabla ya hidden.bs.modal
tukio kutokea).
myModal.hide()
kushughulikiaSasisho
Rekebisha mwenyewe nafasi ya modali ikiwa urefu wa modali hubadilika wakati iko wazi (yaani ikiwa upau wa kusogeza utatokea).
myModal.handleUpdate()
tupa
Huharibu modi ya kipengele. (Huondoa data iliyohifadhiwa kwenye kipengele cha DOM)
myModal.dispose()
getInstance
Njia tuli ambayo hukuruhusu kupata mfano wa modal unaohusishwa na kipengee cha DOM
var myModalEl = document.getElementById('myModal')
var modal = bootstrap.Modal.getInstance(myModalEl) // Returns a Bootstrap modal instance
getOrCreateInstance
Njia tuli ambayo hukuruhusu kupata mfano wa modal unaohusishwa na kipengee cha DOM, au kuunda mpya ikiwa haikuanzishwa.
var myModalEl = document.querySelector('#myModal')
var modal = bootstrap.Modal.getOrCreateInstance(myModalEl) // Returns a Bootstrap modal instance
Matukio
Darasa la modali la Bootstrap linafichua matukio machache ya kuunganisha kwenye utendakazi wa modal. Matukio yote ya modal yanarushwa kwa modali yenyewe (yaani kwenye <div class="modal">
).
Aina ya tukio | Maelezo |
---|---|
show.bs.modal |
Tukio hili huwaka mara moja wakati show njia ya mfano inaitwa. Ikisababishwa na kubofya, kipengele kilichobofya kinapatikana kama sifa relatedTarget ya tukio. |
shown.bs.modal |
Tukio hili linafutwa wakati modali imefanywa kuonekana kwa mtumiaji (itasubiri mabadiliko ya CSS kukamilika). Ikisababishwa na kubofya, kipengele kilichobofya kinapatikana kama sifa relatedTarget ya tukio. |
hide.bs.modal |
Tukio hili linafutwa mara moja wakati hide njia ya mfano imeitwa. |
hidden.bs.modal |
Tukio hili litafutwa wakati modali imekamilika kufichwa kutoka kwa mtumiaji (itasubiri mabadiliko ya CSS kukamilika). |
hidePrevented.bs.modal |
Tukio hili hutupwa wakati modali inaonyeshwa, mandhari yake ni static na kubofya nje ya modali au ubonyezo wa kitufe cha kutoroka hufanywa kwa chaguo la kibodi au data-bs-keyboard kuweka false . |
var myModalEl = document.getElementById('myModal')
myModalEl.addEventListener('hidden.bs.modal', function (event) {
// do something...
})
