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.

Air an duilleig seo

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 .

html 
<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>

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.

Eisimpleir beò

Cliog air a’ phutan gu h-ìosal gus rabhadh a nochdadh (falaichte le stoidhlichean in-loidhne airson tòiseachadh), an uairsin cuir às (agus sgrios) e leis a’ phutan dlùth togte.

html 
<div id="liveAlertPlaceholder"></div>
<button type="button" class="btn btn-primary" id="liveAlertBtn">Show live alert</button>

Bidh sinn a’ cleachdadh an JavaScript a leanas gus an demo rabhaidh beò againn a bhrosnachadh:

const alertPlaceholder = document.getElementById('liveAlertPlaceholder')

const alert = (message, type) => {
  const wrapper = document.createElement('div')
  wrapper.innerHTML = [
    `<div class="alert alert-${type} alert-dismissible" role="alert">`,
    `   <div>${message}</div>`,
    '   <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>',
    '</div>'
  ].join('')

  alertPlaceholder.append(wrapper)
}

const alertTrigger = document.getElementById('liveAlertBtn')
if (alertTrigger) {
  alertTrigger.addEventListener('click', () => {
    alert('Nice, you triggered this alert message!', 'success')
  })
}

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

html 
<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.

html 
<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.

html 
<div class="alert alert-primary d-flex align-items-center" role="alert">
  <svg xmlns="http://www.w3.org/2000/svg" class="bi bi-exclamation-triangle-fill flex-shrink-0 me-2" viewBox="0 0 16 16" role="img" aria-label="Warning:">

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:

html 
<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.

CSS

Caochlaidhean

Air a chur ris ann an v5.2.0

Mar phàirt de dhòigh-obrach caochladairean CSS Bootstrap, tha rabhaidhean a-nis a’ cleachdadh caochladairean CSS ionadail air adhart .alertairson gnàthachadh fìor-ùine leasaichte. Tha luachan airson caochladairean CSS air an suidheachadh tro Sass, agus mar sin tha gnàthachadh Sass fhathast a’ faighinn taic, cuideachd.

  --#{$prefix}alert-bg: transparent;
  --#{$prefix}alert-padding-x: #{$alert-padding-x};
  --#{$prefix}alert-padding-y: #{$alert-padding-y};
  --#{$prefix}alert-margin-bottom: #{$alert-margin-bottom};
  --#{$prefix}alert-color: inherit;
  --#{$prefix}alert-border-color: transparent;
  --#{$prefix}alert-border: #{$alert-border-width} solid var(--#{$prefix}alert-border-color);
  --#{$prefix}alert-border-radius: #{$alert-border-radius};

caochladairean Sass

$alert-padding-y:               $spacer;
$alert-padding-x:               $spacer;
$alert-margin-bottom:           1rem;
$alert-border-radius:           $border-radius;
$alert-link-font-weight:        $font-weight-bold;
$alert-border-width:            $border-width;
$alert-bg-scale:                -80%;
$alert-border-scale:            -70%;
$alert-color-scale:             40%;
$alert-dismissible-padding-r:   $alert-padding-x * 3; // 3x covers width of x plus default padding on either side

Sass measgachadh

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

@mixin alert-variant($background, $border, $color) {
  --#{$prefix}alert-color: #{$color};
  --#{$prefix}alert-bg: #{$background};
  --#{$prefix}alert-border-color: #{$border};

  @if $enable-gradients {
    background-image: var(--#{$prefix}gradient);
  }

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

lùb sass

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

Tòiseachadh

Tòisich eileamaidean mar rabhaidhean

const alertList = document.querySelectorAll('.alert')
const alerts = [...alertList].map(element => new bootstrap.Alert(element))

Airson an aon adhbhar rabhadh a chuir às, chan fheumar am pàirt a thòiseachadh le làimh tron ​​​​JS API. Le bhith a’ cleachdadh data-bs-dismiss="alert", thèid am pàirt a thòiseachadh gu fèin-ghluasadach agus a chuir às gu ceart.

Faic an roinn brosnachaidh airson tuilleadh fiosrachaidh.

Luchd-brosnachaidh

Faodar cur às a dhreuchd leis a’ datafheart air putan taobh a-staigh an rabhaidh mar a chithear gu h-ìosal:

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

no air putan taobh a-muigh an rabhaidh a’ cleachdadh data-bs-targetmar a chithear gu h-ìosal:

<button type="button" class="btn-close" data-bs-dismiss="alert" data-bs-target="#my-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:

const 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. Mar eisimpleir: 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).

Cleachdadh bunaiteach:

const alert = bootstrap.Alert.getOrCreateInstance('#myAlert')
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. 
const myAlert = document.getElementById('myAlert')
myAlert.addEventListener('closed.bs.alert', event => {
  // 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()
})
