Kif taħdem

Offcanvas huwa komponent tal-istrixxa tal-ġenb li jista' jinbidel permezz ta' JavaScript biex jidher mit-tarf tax-xellug, tal-lemin, ta' fuq jew ta' isfel tal-viewport. Buttuni jew ankri jintużaw bħala triggers li huma mehmuża ma 'elementi speċifiċi li taqleb, u dataattributi jintużaw biex jinvokaw JavaScript tagħna.

Offcanvas jaqsam xi wħud mill-istess kodiċi JavaScript bħall-modali. Kunċettwalment, huma pjuttost simili, iżda huma plugins separati.
Bl-istess mod, xi sors Sass għall-istili u d-dimensjonijiet ta 'offcanvas jintirtu mill-varjabbli tal-modal.
Meta jintwera, offcanvas jinkludi sfond default li jista' jiġi kklikkjat biex jaħbi l-offcanvas.
Simili għall-modali, offcanvas wieħed biss jista' jintwera kull darba.

Irjus up! Minħabba kif is-CSS jimmaniġġja l-animazzjonijiet, ma tistax tuża marginjew translatefuq .offcanvaselement. Minflok, uża l-klassi bħala element indipendenti tat-tgeżwir.

L-effett ta 'animazzjoni ta' dan il-komponent jiddependi fuq il prefers-reduced-motion-mistoqsija tal-midja. Ara t- taqsima tal-mozzjoni mnaqqsa tad-dokumentazzjoni tagħna dwar l-aċċessibbiltà .

Eżempji

Komponenti offcanvas

Hawn taħt hemm eżempju offcanvas li jidher awtomatikament (permezz ta' .showfuq .offcanvas). Offcanvas jinkludi appoġġ għal header b'buttuna mill-qrib u klassi tal-ġisem fakultattiva għal xi inizjali padding. Nissuġġerixxu li tinkludi headers offcanvas b'azzjonijiet ta' ċaħda kull meta jkun possibbli, jew tipprovdi azzjoni ta' ċaħda espliċita.

Il-kontenut għall-offcanvas imur hawn. Tista 'tpoġġi kważi kull komponent Bootstrap jew elementi tad-dwana hawn.

Uża l-buttuni hawn taħt biex turi u taħbi element offcanvas permezz ta' JavaScript li jbiddel il- .showklassi fuq element mal- .offcanvasklassi.

.offcanvasjaħbi l-kontenut (default)
.offcanvas.showjuri kontenut

Tista' tuża link bl- hrefattribut, jew buttuna bl- data-bs-targetattribut. Fiż-żewġ każijiet, data-bs-toggle="offcanvas"huwa meħtieġ.

Rabta ma href

Xi test bħala placeholder. Fil-ħajja reali jista' jkollok l-elementi li għażilt. Bħal, test, stampi, listi, eċċ.

html

<a class="btn btn-primary" data-bs-toggle="offcanvas" href="#offcanvasExample" role="button" aria-controls="offcanvasExample">
  Link with href
</a>
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasExample" aria-controls="offcanvasExample">
  Button with data-bs-target

Scrolling tal-ġisem

L-iskrolljar tal- <body>element huwa diżattivat meta offcanvas u l-isfond tiegħu jkunu viżibbli. Uża l- data-bs-scrollattribut biex tippermetti <body>scrolling.

Ipprova skrollja l-bqija tal-paġna biex tara din l-għażla fl-azzjoni.

html

<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasScrolling" aria-controls="offcanvasScrolling">Enable body scrolling</button>

  </div>
</div>

Scrolling tal-ġisem u sfond

Tista 'wkoll tippermetti <body>scrolling bi sfond viżibbli.

Ipprova skrollja l-bqija tal-paġna biex tara din l-għażla fl-azzjoni.

html

Jirrispondi

Miżjud fi v5.2.0

Klassijiet offcanvas li jirreaġixxu jaħbu l-kontenut barra l-viewport minn breakpoint speċifikat u 'l isfel. Fuq dak il-punt ta' waqfien, il-kontenut ġewwa se jġib ruħu bħas-soltu. Pereżempju, .offcanvas-lgjaħbi l-kontenut f'kanvas offcanvas taħt il- punt ta' lgwaqfien, iżda juri l-kontenut 'il fuq mill- punt ta' lgwaqfien.

Id-daqs tal-browser tiegħek biex turi l-toggle offcanvas li jirrispondu.

Dan huwa kontenut fi ħdan .offcanvas-lg.

Aċċessibilità

Peress li l-panel offcanvas huwa kunċettwalment dialog modali, kun żgur li żżid aria-labelledby="..."—b'referenza għat-titlu offcanvas—ma' .offcanvas. Innota li m'għandekx bżonn iżżidrole="dialog" peress li aħna diġà nżiduha permezz ta' JavaScript.

CSS

Varjabbli

Miżjud fi v5.2.0

Bħala parti mill-approċċ tal-varjabbli tas-CSS li qed jevolvu ta' Bootstrap, offcanvas issa juża varjabbli tas-CSS lokali fuq .offcanvasgħal customization imtejjeb f'ħin reali. Il-valuri għall-varjabbli CSS huma stabbiliti permezz ta 'Sass, għalhekk il-personalizzazzjoni ta' Sass għadha appoġġjata wkoll.

  --#{$prefix}offcanvas-zindex: #{$zindex-offcanvas};
  --#{$prefix}offcanvas-width: #{$offcanvas-horizontal-width};
  --#{$prefix}offcanvas-height: #{$offcanvas-vertical-height};
  --#{$prefix}offcanvas-padding-x: #{$offcanvas-padding-x};
  --#{$prefix}offcanvas-padding-y: #{$offcanvas-padding-y};
  --#{$prefix}offcanvas-color: #{$offcanvas-color};
  --#{$prefix}offcanvas-bg: #{$offcanvas-bg-color};
  --#{$prefix}offcanvas-border-width: #{$offcanvas-border-width};
  --#{$prefix}offcanvas-border-color: #{$offcanvas-border-color};
  --#{$prefix}offcanvas-box-shadow: #{$offcanvas-box-shadow};

$offcanvas-backdrop-bg:             $modal-backdrop-bg;
$offcanvas-backdrop-opacity:        $modal-backdrop-opacity;

Użu

Il-plugin offcanvas juża ftit klassijiet u attributi biex jimmaniġġja l-irfigħ tqil:

.offcanvasjaħbi l-kontenut
.offcanvas.showjuri l-kontenut
.offcanvas-startjaħbi l-offcanvas fuq ix-xellug
.offcanvas-endjaħbi l-offcanvas fuq il-lemin
.offcanvas-topjaħbi l-offcanvas fuq nett
.offcanvas-bottomjaħbi l-offcanvas fil-qiegħ

Żid buttuna tkeċċi bl- data-bs-dismiss="offcanvas"attribut, li tixpruna l-funzjonalità JavaScript. Kun żgur li tuża l- <button>element miegħu għal imġieba xierqa fl-apparati kollha.

Via attributi tad-data

Toggle

Żid data-bs-toggle="offcanvas"u a data-bs-targetjew hrefmal-element biex awtomatikament tassenja l-kontroll ta 'element offcanvas wieħed. L- data-bs-targetattribut jaċċetta selettur CSS biex japplika l-offcanvas għalih. Kun żgur li żżid il-klassi offcanvasmal-element offcanvas. Jekk tixtieq li tiftaħ awtomatikament, żid il-klassi addizzjonalishow .

Tkeċċi

It-tkeċċija tista' tinkiseb bl- dataattribut fuq buttuna fi ħdan l-offcanvas kif muri hawn taħt:

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

jew fuq buttuna barra l-offcanvas billi tuża data-bs-targetkif muri hawn taħt:

<button type="button" class="btn-close" data-bs-dismiss="offcanvas" data-bs-target="#my-offcanvas" aria-label="Close"></button>

Filwaqt li ż-żewġ modi biex titneħħa offcanvas huma appoġġjati, żomm f'moħħok li t-tkeċċija minn barra offcanvas ma taqbilx mal- mudell tad-djalogu (modali) tal-Gwida tal-Prattiċi tal-Awtur ARIA . Agħmel dan bir-riskju tiegħek.

Via JavaScript

Ippermetti manwalment ma':

const offcanvasElementList = document.querySelectorAll('.offcanvas')
const offcanvasList = [...offcanvasElementList].map(offcanvasEl => new bootstrap.Offcanvas(offcanvasEl))

Għażliet

Peress li l-għażliet jistgħu jiġu mgħoddija permezz ta' attributi tad-dejta jew JavaScript, tista' tehmeż isem ta' għażla ma' data-bs-, bħal f' data-bs-animation="{value}". Kun żgur li tbiddel it-tip tal-każ tal-isem tal-għażla minn " camelCase " għal " kebab-case " meta tgħaddi l-għażliet permezz tal-attributi tad-dejta. Per eżempju, uża data-bs-custom-class="beautifier"minflok data-bs-customClass="beautifier".

Minn Bootstrap 5.2.0, il-komponenti kollha jappoġġaw attribut ta' data riżervat sperimentalidata-bs-config li jista' jospita konfigurazzjoni ta' komponent sempliċi bħala string JSON. Meta element ikollu data-bs-config='{"delay":0, "title":123}'u data-bs-title="456"attributi, il- titlevalur finali se jkun 456u l-attributi tad-dejta separati jegħlbu l-valuri mogħtija fuq data-bs-config. Barra minn hekk, l-attributi tad-dejta eżistenti jistgħu jospitaw valuri JSON bħal data-bs-delay='{"show":0,"hide":150}'.

Isem	Tip	Default	Deskrizzjoni
`backdrop`	boolean jew is-sekwenza`static`	`true`	Applika sfond fuq il-ġisem waqt li l-offcanvas ikun miftuħ. Inkella, speċifika `static`għal sfond li ma jagħlaqx l-offcanvas meta tagħfas.
`keyboard`	boolean	`true`	Jagħlaq il-offcanvas meta tagħfas iċ-ċavetta tal-ħarba.
`scroll`	boolean	`false`	Ħalli l-iskrolljar tal-ġisem waqt li l-offcanvas ikun miftuħ.

Jattiva l-kontenut tiegħek bħala element offcanvas. Jaċċetta għażliet fakultattivi object.

Tista' toħloq istanza offcanvas mal-kostruttur, pereżempju:

const bsOffcanvas = new bootstrap.Offcanvas('#myOffcanvas')

Metodu	Deskrizzjoni
`getInstance`	Metodu statiku li jippermettilek tikseb l-istanza offcanvas assoċjata ma 'element DOM.
`getOrCreateInstance`	Metodu statiku li jippermettilek li tikseb l-istanza offcanvas assoċjata ma 'element DOM, jew toħloq waħda ġdida f'każ li ma kienx inizjalizzat.
`hide`	Jaħbi element offcanvas. Jirritorna lil min iċempel qabel ma l-element offcanvas fil-fatt ġie moħbi (jiġifieri qabel ma `hidden.bs.offcanvas`jseħħ l-avveniment).
`show`	Juri element offcanvas. Jirritorna lil min iċempel qabel ma l-element offcanvas fil-fatt intwera (jiġifieri qabel ma `shown.bs.offcanvas`jseħħ l-avveniment).
`toggle`	Jiddawwar element barra mill-kanvas biex jintwera jew moħbi. Jirritorna lil min iċempel qabel ma l-element offcanvas fil-fatt ġie muri jew moħbi (jiġifieri qabel ma jseħħ l-avveniment `shown.bs.offcanvas`jew ).`hidden.bs.offcanvas`

Avvenimenti

Il-klassi offcanvas ta 'Bootstrap tesponi ftit avvenimenti biex tgħaqqad il-funzjonalità offcanvas.

Tip ta' avveniment	Deskrizzjoni
`hide.bs.offcanvas`	Dan l-avveniment jiġi sparat immedjatament meta l- `hide`metodu jkun ġie msejjaħ.
`hidden.bs.offcanvas`	Dan l-avveniment jiġi sparat meta element offcanvas ikun ġie moħbi mill-utent (se jistenna li jitlestew it-tranżizzjonijiet CSS).
`hidePrevented.bs.offcanvas`	Dan l-avveniment jiġi sparat meta jintwera l-offcanvas, l-isfond tiegħu jkun `static`u ssir ikklikkja barra mill-offcanvas. L-avveniment jiġi sparat ukoll meta ċ-ċavetta tal-ħarba tiġi ppressata u l- `keyboard`għażla tkun issettjata għal `false`.
`show.bs.offcanvas`	Dan l-avveniment jispara immedjatament meta `show`jissejjaħ il-metodu tal-istanza.
`shown.bs.offcanvas`	Dan l-avveniment jiġi sparat meta element offcanvas ikun sar viżibbli għall-utent (se jistenna li t-tranżizzjonijiet CSS jitlestew).

const myOffcanvas = document.getElementById('myOffcanvas')
myOffcanvas.addEventListener('hidden.bs.offcanvas', event => {
