Rabhaidhean

Thoir seachad teachdaireachdan fios air ais co-theacsail airson gnìomhan àbhaisteach luchd-cleachdaidh leis an dòrlach de theachdaireachdan rabhaidh sùbailte a tha rim faighinn.

Eisimpleirean

Tha rabhaidhean rim faighinn airson fad teacsa sam bith, a bharrachd air putan dùnadh roghainneil. Airson stoidhle ceart, cleachd aon de na h-ochd clasaichean co-theacsail a tha a dhìth (me, .alert-success). Airson cuir às do dhreuchd in-loidhne, cleachd am plugan rabhaidhean JavaScript .

<div class="alert alert-primary" role="alert">
  A simple primary alert—check it out!
</div>
<div class="alert alert-secondary" role="alert">
  A simple secondary alert—check it out!
</div>
<div class="alert alert-success" role="alert">
  A simple success alert—check it out!
</div>
<div class="alert alert-danger" role="alert">
  A simple danger alert—check it out!
</div>
<div class="alert alert-warning" role="alert">
  A simple warning alert—check it out!
</div>
<div class="alert alert-info" role="alert">
  A simple info alert—check it out!
</div>
<div class="alert alert-light" role="alert">
  A simple light alert—check it out!
</div>
<div class="alert alert-dark" role="alert">
  A simple dark alert—check it out!
</div>
A’ toirt brìgh do theicneòlasan cuideachail

Chan eil a bhith a’ cleachdadh dath gus brìgh a chur ris ach a’ toirt seachad sealladh lèirsinneach, nach tèid a thoirt do luchd-cleachdaidh theicneòlasan taice - leithid leughadairean sgrion. Dèan cinnteach gu bheil fiosrachadh air a chomharrachadh leis an dath an dàrna cuid follaiseach bhon t-susbaint fhèin (me an teacsa faicsinneach), no air a thoirt a-steach tro dhòighean eile, leithid teacsa a bharrachd falaichte leis a’ .visually-hiddenchlas.

Cleachd an .alert-linkclas goireis gus ceanglaichean dathte a thoirt seachad gu sgiobalta taobh a-staigh rabhadh sam bith.

<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">
  A simple secondary alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-success" role="alert">
  A simple success alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-danger" role="alert">
  A simple danger alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-warning" role="alert">
  A simple warning alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-info" role="alert">
  A simple info alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-light" role="alert">
  A simple light alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-dark" role="alert">
  A simple dark alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>

Susbaint a bharrachd

Faodaidh eileamaidean HTML a bharrachd a bhith ann an rabhaidhean mar cinn, paragrafan agus luchd-sgaraidh.

<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>

Ìomhaighean

San aon dòigh, faodaidh tu goireasan flexbox agus Bootstrap Icons a chleachdadh gus rabhaidhean a chruthachadh le ìomhaighean. A rèir na h-ìomhaighean agus an t-susbaint agad, is dòcha gum bi thu airson barrachd ghoireasan no stoidhlichean àbhaisteach a chuir ris.

A' cur às

Le bhith a’ cleachdadh am plugan rabhadh JavaScript, tha e comasach cuir às do rabhadh in-loidhne sam bith. Seo mar a tha:

  • Dèan cinnteach gu bheil thu air am plugan rabhaidh, no am Bootstrap JavaScript a chuir ri chèile.
  • Cuir putan dlùth ris agus an .alert-dismissibleclas, a chuireas pleadhag a bharrachd air taobh deas an rabhaidh agus a chuireas am putan dlùth ris.
  • Air a’ phutan dlùth, cuir am data-bs-dismiss="alert"feart ris, a bhrosnaicheas gnìomhachd JavaScript. Dèan cinnteach gun cleachd thu an <button>eileamaid leis airson giùlan ceart thar gach inneal.
  • Gus rabhaidhean a bheothachadh nuair a thèid an cur às, bi cinnteach gun cuir thu na clasaichean .fadeagus na .showclasaichean ris.

Chì thu seo ann an gnìomh le demo beò:

<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="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
</div>
Nuair a thèid rabhadh a chuir às, thèid an eileamaid a thoirt air falbh gu tur bho structar na duilleige. Ma chuireas neach-cleachdaidh meur-chlàr às don rabhadh leis a’ phutan dùin, thèid am fòcas a chall gu h-obann agus, a rèir a’ bhrobhsair, ath-shuidhichidh e gu toiseach na duilleige/sgrìobhainn. Air an adhbhar seo, tha sinn a 'moladh a bhith a' toirt a-steach JavaScript a bharrachd a bhios ag èisteachd airson an closed.bs.alerttachartais agus a 'suidheachadh gu prògram focus()chun an àite as freagarraiche air an duilleag. Ma tha thu an dùil fòcas a ghluasad gu eileamaid neo-eadar-ghnìomhach nach àbhaist a bhith a’ faighinn fòcas, dèan cinnteach gun cuir thu ris tabindex="-1"an eileamaid.

Measgachadh caochlaideach

Air a chleachdadh còmhla ri $theme-colorsgus clasaichean atharrachaidh co-theacsail a chruthachadh airson ar rabhaidhean.

@mixin alert-variant($background, $border, $color) {
  color: $color;
  @include gradient-bg($background);
  border-color: $border;

  .alert-link {
    color: shade-color($color, 20%);
  }
}

Lùb

Lùb a ghineas na clasaichean mion-atharrachaidh leis a’ alert-variant()mheasgachadh.

// Generate contextual modifier classes for colorizing the alert.

@each $state, $value in $theme-colors {
  $alert-background: shift-color($value, $alert-bg-scale);
  $alert-border: shift-color($value, $alert-border-scale);
  $alert-color: shift-color($value, $alert-color-scale);
  @if (contrast-ratio($alert-background, $alert-color) < $min-contrast-ratio) {
    $alert-color: mix($value, color-contrast($alert-background), abs($alert-color-scale));
  }
  .alert-#{$state} {
    @include alert-variant($alert-background, $alert-border, $alert-color);
  }
}

Giùlan JavaScript

Luchd-brosnachaidh

Dèan comas air rabhadh a chuir às tro JavaScript:

var alertList = document.querySelectorAll('.alert')
alertList.forEach(function (alert) {
  new bootstrap.Alert(alert)
})

No le databuadhan air putan taobh a-staigh an rabhaidh , mar a chithear gu h-àrd:

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

Thoir an aire gun toir dùnadh rabhadh air falbh e bhon DOM.

Dòighean-obrach

Faodaidh tu eisimpleir rabhaidh a chruthachadh leis an neach-togail rabhaidh, mar eisimpleir:

var myAlert = document.getElementById('myAlert')
var bsAlert = new bootstrap.Alert(myAlert)

Bheir seo air rabhadh èisteachd airson tachartasan cliog air eileamaidean sliochd aig a bheil am data-bs-dismiss="alert"feart. (Chan eil sin riatanach nuair a thathar a’ cleachdadh fèin-thòiseachadh data-api.)

Dòigh-obrach Tuairisgeul
close A’ dùnadh rabhadh le bhith ga thoirt air falbh bhon DOM. Ma tha na clasaichean .fadeagus .showan làthair air an eileamaid, falbhaidh an rabhadh mus tèid a thoirt air falbh.
dispose A 'sgrios rabhadh eileamaid. (Thoir air falbh dàta air a stòradh air an eileamaid DOM)
getInstance Modh statach a leigeas leat an eisimpleir rabhaidh fhaighinn co-cheangailte ri eileamaid DOM, faodaidh tu a chleachdadh mar seo:bootstrap.Alert.getInstance(alert)
getOrCreateInstance Modh statach a thilleas eisimpleir rabhaidh co-cheangailte ri eileamaid DOM no a chruthaicheas fear ùr gun fhios nach deach a thòiseachadh. Faodaidh tu a chleachdadh mar seo:bootstrap.Alert.getOrCreateInstance(element) 
var alertNode = document.querySelector('.alert')
var alert = bootstrap.Alert.getInstance(alertNode)
alert.close()

Tachartasan

Bidh plugan rabhaidh Bootstrap a’ nochdadh grunn thachartasan airson a dhol a-steach do ghnìomhachd rabhaidh.

Tachartas Tuairisgeul
close.bs.alert A’ losgadh sa bhad nuair closea chanar ris an dòigh eisimpleir.
closed.bs.alert Air a losgadh nuair a tha an rabhadh air a dhùnadh agus eadar-ghluasadan CSS deiseil. 
var myAlert = document.getElementById('myAlert')
myAlert.addEventListener('closed.bs.alert', function () {
  // do something, for instance, explicitly move focus to the most appropriate element,
  // so it doesn't get lost/reset to the start of the page
  // document.getElementById('...').focus()
})
