Toasts

Pouse notifikasyon bay vizitè ou yo ak yon pen griye, yon mesaj alèt ki lejè ak fasil personnalisable.

Toasts se notifikasyon ki lejè ki fèt pou imite notifikasyon pouse ke sistèm operasyon mobil ak Desktop yo te popilè. Yo bati ak flexbox, kidonk yo fasil pou aliman ak pozisyon.

Apèsi sou lekòl la

Bagay ou dwe konnen lè w ap itilize plugin pen griye:

  • Si w ap konstwi JavaScript nou an soti nan sous, li mande pouutil.js .
  • Toasts yo patisipe pou rezon pèfòmans, kidonk ou dwe inisyalize yo tèt ou .
  • Tanpri sonje ke ou responsab pou pwezante pen griye.
  • Toasts ap kache otomatikman si ou pa presize autohide: false.

Egzanp yo

Debaz

Pou ankouraje pen griye extensible ak previzib, nou rekòmande yon header ak kò. Tèt pen griye itilize display: flex, sa ki pèmèt aliyman fasil nan kontni gras a maj nou yo ak sèvis piblik flexbox.

Toasts yo fleksib jan ou bezwen epi yo gen yon ti kras maketing obligatwa. Omwen, nou mande pou yon sèl eleman ki genyen kontni "griye" ou epi ankouraje fòtman yon bouton anile.

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small>11 mins ago</small>
    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="toast-body">
    Hello, world! This is a toast message.
  </div>
</div>

Translusid

Griye yo tou yon ti kras translusid, kidonk yo melanje sou tou sa yo ta ka parèt sou. Pou navigatè ki sipòte backdrop-filterpwopriyete CSS la, nou pral eseye tou flou eleman yo anba yon pen griye.

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="text-muted">11 mins ago</small>
    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="toast-body">
    Hello, world! This is a toast message.
  </div>
</div>

Anpile

Lè ou gen plizyè toasts, nou pa default anpile yo vètikal nan yon fason lizib.

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="text-muted">just now</small>
    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="toast-body">
    See? Just like this.
  </div>
</div>

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="text-muted">2 seconds ago</small>
    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="toast-body">
    Heads up, toasts will stack automatically
  </div>
</div>

Plasman

Mete pen griye ak CSS koutim jan ou bezwen yo. Anwo dwat la souvan itilize pou notifikasyon, menm jan ak mitan an tèt. Si w ap montre sèlman yon pen griye nan yon moman, mete estil pozisyon yo dwat sou .toast.

Bootstrap 11 minit de sa
Bonjou, mond! Sa a se yon mesaj pen griye. 
<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
  <div class="toast" style="position: absolute; top: 0; right: 0;">
    <div class="toast-header">
      <img src="..." class="rounded mr-2" alt="...">
      <strong class="mr-auto">Bootstrap</strong>
      <small>11 mins ago</small>
      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
        <span aria-hidden="true">&times;</span>
      </button>
    </div>
    <div class="toast-body">
      Hello, world! This is a toast message.
    </div>
  </div>
</div>

Pou sistèm ki jenere plis notifikasyon, konsidere itilize yon eleman anbalaj pou yo ka fasilman pile.

<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
  <!-- Position it -->
  <div style="position: absolute; top: 0; right: 0;">

    <!-- Then put toasts within -->
    <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
      <div class="toast-header">
        <img src="..." class="rounded mr-2" alt="...">
        <strong class="mr-auto">Bootstrap</strong>
        <small class="text-muted">just now</small>
        <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="toast-body">
        See? Just like this.
      </div>
    </div>

    <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
      <div class="toast-header">
        <img src="..." class="rounded mr-2" alt="...">
        <strong class="mr-auto">Bootstrap</strong>
        <small class="text-muted">2 seconds ago</small>
        <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="toast-body">
        Heads up, toasts will stack automatically
      </div>
    </div>
  </div>
</div>

Ou ka jwenn anpenpan tou ak sèvis piblik flexbox pou fè aliman pen griye orizontal ak / oswa vètikal.

<!-- Flexbox container for aligning the toasts -->
<div aria-live="polite" aria-atomic="true" class="d-flex justify-content-center align-items-center" style="min-height: 200px;">

  <!-- Then put toasts within -->
  <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
    <div class="toast-header">
      <img src="..." class="rounded mr-2" alt="...">
      <strong class="mr-auto">Bootstrap</strong>
      <small>11 mins ago</small>
      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
        <span aria-hidden="true">&times;</span>
      </button>
    </div>
    <div class="toast-body">

Aksesiblite

Toasts yo gen entansyon fè ti entèripsyon pou vizitè ou oswa itilizatè yo, kidonk pou ede moun ki gen lektè ekran ak teknoloji asistans ki sanble, ou ta dwe vlope pen griye ou nan yon aria-liverejyon . Chanjman nan rejyon viv (tankou enjekte / ajou yon eleman pen griye) otomatikman anonse pa lektè ekran san yo pa bezwen deplase konsantre itilizatè a oswa otreman entèwonp itilizatè a. Anplis de sa, enkli aria-atomic="true"pou asire ke tout pen griye a toujou anonse kòm yon sèl inite (atomik), olye ke anonse sa ki te chanje (ki ta ka mennen nan pwoblèm si ou sèlman mete ajou yon pati nan kontni pen griye a, oswa si montre menm kontni pen griye a nan yon moman pita nan tan). Si enfòmasyon ki nesesè yo enpòtan pou pwosesis la, pa egzanp pou yon lis erè nan yon fòm, Lè sa a, sèvi ak eleman alèt la .olye pou yo pen griye.

Remake byen ke rejyon an ap viv la bezwen prezan nan maketing la anvan pen griye a te pwodwi oswa mete ajou. Si ou dinamik jenere tou de an menm tan epi enjekte yo nan paj la, jeneralman yo pa pral anonse pa teknoloji asistans.

Ou bezwen tou adapte a roleak aria-livenivo depann sou kontni an. Si se yon mesaj enpòtan tankou yon erè, sèvi ak role="alert" aria-live="assertive", otreman sèvi ak role="status" aria-live="polite"atribi.

Pandan kontni w ap montre a ap chanje, asire w ke ou mete ajou tan an delaypou asire moun yo gen ase tan pou li pen griye a.

<div class="toast" role="alert" aria-live="polite" aria-atomic="true" data-delay="10000">
  <div role="alert" aria-live="assertive" aria-atomic="true">...</div>
</div>

Lè w ap itilize autohide: false, ou dwe ajoute yon bouton fèmen pou pèmèt itilizatè yo ranvwaye pen griye a.

<div role="alert" aria-live="assertive" aria-atomic="true" class="toast" data-autohide="false">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small>11 mins ago</small>
    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="toast-body">
    Hello, world! This is a toast message.
  </div>
</div>

Metòd

Metòd asynchrone ak tranzisyon

Tout metòd API yo asenkron epi yo kòmanse yon tranzisyon . Yo retounen kote moun k ap rele a le pli vit ke tranzisyon an kòmanse men anvan li fini . Anplis de sa, yo pral inyore yon apèl metòd sou yon eleman tranzisyon .

$().toast(options)

Tache yon moun k ap okipe pen griye nan yon koleksyon eleman.

.toast('show')

Revele pen griye yon eleman. Retounen bay moun k ap rele a anvan yo te montre pen griye a (sa vle di anvan shown.bs.toastevènman an rive). Ou gen manyèlman rele metòd sa a, olye pen griye ou a pa pral montre.

$('#element').toast('show')

.toast('hide')

Kache pen griye yon eleman. Retounen bay moun kap rele a anvan pen griye a te kache (sa vle di anvan hidden.bs.toastevènman an rive). Ou dwe manyèlman rele metòd sa a si ou te fè autohidenan false.

$('#element').toast('hide')
