Transmèt siyifikasyon nan teknoloji asistans

Sèvi ak koulè pou ajoute siyifikasyon sèlman bay yon endikasyon vizyèl, ki pa pral transmèt bay itilizatè teknoloji asistans - tankou lektè ekran. Asire w ke enfòmasyon ki endike nan koulè a ​​se swa evidan nan kontni an li menm (egzanp tèks vizib la), oswa yo enkli nan mwayen altènatif, tankou tèks adisyonèl kache ak .sr-onlyklas la.

Sèvi ak .alert-linkklas sèvis piblik la byen vit bay lyen ki gen koulè ki matche nan nenpòt alèt.

<div class="alert alert-primary" role="alert">
  A simple primary alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-secondary" role="alert">

Alèt yo kapab genyen tou eleman HTML adisyonèl tankou tit, paragraf ak divize.

<div class="alert alert-success" role="alert">
  <h4 class="alert-heading">Well done!</h4>
  <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
  <hr>
  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>

Ranvwaye

Lè l sèvi avèk plugin JavaScript alèt la, li posib pou ranvwaye nenpòt alèt inline. Men ki jan:

  • Asire w ou te chaje plugin alèt la, oubyen konpile Bootstrap JavaScript.
  • Si w ap konstwi JavaScript nou an soti nan sous, li mande pouutil.js . Vèsyon an konpile gen ladan sa a.
  • Ajoute yon bouton ranvwaye ak .alert-dismissibleklas la, ki ajoute siplemantè padding adwat alèt la ak pozisyon .closebouton an.
  • Sou bouton an ranvwaye, ajoute data-dismiss="alert"atribi a, ki deklanche fonksyonalite JavaScript. Asire ou ke ou sèvi ak <button>eleman nan ak li pou bon konpòtman atravè tout aparèy.
  • Pou anime alèt lè w ap ranvwaye yo, asire w ke ou ajoute .fadeak .showklas yo.

Ou ka wè sa a an aksyon ak yon Demo ap viv:

<div class="alert alert-warning alert-dismissible fade show" role="alert">
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  <button type="button" class="close" data-dismiss="alert" aria-label="Close">
    <span aria-hidden="true">&times;</span>
  </button>
</div>

Konpòtman JavaScript

Deklanche

Pèmèt ranvwa yon alèt via JavaScript:

$('.alert').alert()

Oswa ak dataatribi sou yon bouton nan alèt la , jan sa montre pi wo a:

<button type="button" class="close" data-dismiss="alert" aria-label="Close">
  <span aria-hidden="true">&times;</span>
</button>

Remake byen ke fèmen yon alèt pral retire li nan DOM la.

Metòd

Metòd Deskripsyon
$().alert() Fè yon alèt koute pou evènman klike sou eleman desandan ki gen data-dismiss="alert"atribi a. (Pa nesesè lè w ap itilize oto-inisyalizasyon done-api a.)
$().alert('close') Fèmen yon alèt lè w retire li nan DOM la. Si klas yo .fadeak .showyo prezan sou eleman an, alèt la ap disparèt anvan li retire li.
$().alert('dispose') Detwi alèt yon eleman. 
$(".alert").alert('close')

Evènman

Plugin alèt Bootstrap a ekspoze kèk evènman pou branche nan fonksyonalite alèt.

Evènman Deskripsyon
close.bs.alert Evènman sa a dife imedyatman lè yo closerele metòd egzanp lan.
closed.bs.alert Evènman sa a revoke lè alèt la fèmen (ap tann tranzisyon CSS yo fini). 
$('#myAlert').on('closed.bs.alert', function () {
  // do something…
})
