Matohi

Whakaratohia nga karere urupare horopaki mo nga mahi a nga kaiwhakamahi me te ringaringa o nga karere matohi e waatea ana me te ngawari.

I tenei wharangi

Tauira

E waatea ana nga matohi mo te roanga o te kuputuhi, me te paatene kati. Kia tika te hanga, whakamahia tetahi o nga karaehe horopaki e waru ( hei tauira, .alert-success). Mo te whakakore i te raarangi, whakamahia te mono JavaScript matohi .

Te kawe i te tikanga ki nga hangarau awhina

Ko te whakamahi i te tae ki te taapiri i te tikanga he tohu tirohanga noa iho, kaore e tukuna ki nga kaiwhakamahi hangarau awhina - penei i nga kaipanui mata. Me mohio kei te kitea nga korero e tohuhia ana e te tae mai i te ihirangi ake (hei tauira, te tuhinga ka kitea), ka whakaurua ranei ma etahi atu huarahi, penei i etahi atu tuhinga huna ki te .visually-hiddenakomanga.

He tauira ora

Patohia te paatene i raro nei hei whakaatu i tetahi matohi (kua huna me nga momo raarangi hei tiimata), ka peia (ka whakangaro) me te paatene kati kua whakauruhia.

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

Ka whakamahia e matou te JavaScript e whai ake nei hei whakaoho i ta maatau whakaaturanga mataaratanga ora:

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')
  })
}

Whakamahia te .alert-linkkaraehe whaipainga ki te whakarato tere i nga hononga tae orite ki roto i tetahi matohi.

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.

He ihirangi taapiri

Ka taea hoki e nga matohi etahi atu huānga HTML penei i nga pane, nga kowae me nga wehewehenga.

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>

Tohu

Waihoki, ka taea e koe te whakamahi i nga taputapu flexbox me nga Tohu Bootstrap hei hanga matohi me nga tohu. I runga i o tohu me o ihirangi, ka hiahia pea koe ki te taapiri atu i nga taputapu me nga momo ritenga.

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:">

Me neke atu i te kotahi ata mo o matohi? Whakaarohia te whakamahi i etahi atu tohu Bootstrap me te hanga i tetahi sprite SVG o te rohe penei kia ngawari te tohutoro i nga tohu rite tonu.

Te whakakore

Ma te whakamahi i te mono JavaScript matohi, ka taea te whakakore i nga raarangi matohi. Anei me pehea:

  • Kia mahara kua utaina e koe te mono mataara, te Bootstrap JavaScript ranei.
  • Tāpirihia he patene kati me te .alert-dismissiblekaraehe, he taapiri taapiri ki te taha matau o te mataaratanga me te whakanoho i te paatene kati.
  • I runga i te paatene kati, taapirihia te data-bs-dismiss="alert"huanga, e whakaohooho ana i te mahi JavaScript. Me mohio ki te whakamahi i te <button>huānga me taua mea mo te whanonga tika puta noa i nga taputapu katoa.
  • Hei whakakorikori i nga matohi i te wa e whakakore ana i a raatau, me taapiri nga akomanga .fademe .shownga karaehe.

Ka taea e koe te kite i tenei mahi me te whakaaturanga ora:

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>
Ina whakakorehia he matohi, ka tangohia katoatia te huānga mai i te hanganga wharangi. Mena ka whakakorehia e te kaiwhakamahi papapātuhi te matohi ma te whakamahi i te paatene kati, ka ngaro ohorere to ratou arotahi, a, i runga i te tirotiro, ka tautuhi ano ki te timatanga o te wharangi/tuhinga. Mo konei, ka tūtohu kia whakaurua etahi atu JavaScript e whakarongo ana mo te closed.bs.alerthuihuinga me te whakatakoto hotaka focus()ki te waahi e tika ana ki te wharangi. Mēnā kei te whakamahere koe ki te nuku arotahi ki tētahi huānga tauwhitiwhiti kore i te nuinga o te wā karekau i te aro, me whakauru tabindex="-1"ki te huānga.

CSS

Taurangi

Kua taapirihia ki te v5.2.0

Hei waahanga o nga huringa CSS e tipu haere ana a Bootstrap, ka whakamahia e nga matohi nga taurangi CSS o te rohe .alertmo te whakapai ake i te waa-a-waa. Ko nga uara mo nga taurangi CSS ka whakatauhia ma te Sass, no reira kei te tautoko tonu te whakaritenga Sass.

  --#{$prefix}alert-bg: transparent;
  --#{$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};

Taurangi 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 mixin

Ka whakamahia ki $theme-colorste hanga i nga karaehe whakarereke horopaki mo a maatau matohi.

@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%);
  }
}

Sass loop

Koropiko e whakaputa ana i nga karaehe whakarereke me te alert-variant()ranunga.

// 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);
  }
}

Te whanonga JavaScript

Arawhiti

Arawhiti huānga hei matohi

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

Mo te whakakore i te matohi, kaore e tika kia arawhiti-a-ringa te waahanga ma te JS API. Ma te whakamahi i data-bs-dismiss="alert"te , ka arawhiti aunoa i te waahanga ka tika te whakakore.

Tirohia te waahanga keu mo etahi atu taipitopito.

Nga keu

Ka taea te whakakore me te datahuanga i runga i te paatene i roto i te matohi penei i te whakaaturanga i raro nei:

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

i runga ranei i te paatene kei waho o te matohi ma te whakamahi i nga data-bs-targetmea e whakaatuhia ana i raro nei:

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

Kia mahara ko te kati i te matohi ka tangohia mai i te DOM.

Nga tikanga

Ka taea e koe te hanga i tetahi tauira matohi me te kaihanga matohi, hei tauira:

const bsAlert = new bootstrap.Alert('#myAlert')

Ma tenei ka whakarongo matohi mo nga huihuinga panui i runga i nga huānga uri kei a raatau te data-bs-dismiss="alert"huanga. (Kare e tika ina whakamahi i te arataki-aunoa a te raraunga-api.)

Tikanga Whakaahuatanga
close Katia he matohi ma te tango mai i te DOM. Mena kei runga te .fademe .shownga karaehe i runga i te huānga, ka memeha haere te matohi i mua i te tangohanga.
dispose Ka whakakore i te matohi o tetahi huānga. (Tangohia ai nga raraunga rongoa i te huānga DOM)
getInstance Tikanga pateko e taea ai e koe te tiki i te tauira mataara e hono ana ki tetahi huānga DOM. Hei tauira: bootstrap.Alert.getInstance(alert).
getOrCreateInstance Aratuka pateko e whakahoki mai ana i tetahi tauira matohi e hono ana ki tetahi huānga DOM, ki te hanga i tetahi mea hou mena kaore i arawhitia. Ka taea e koe te whakamahi penei bootstrap.Alert.getOrCreateInstance(element):.

Whakamahinga taketake:

const alert = bootstrap.Alert.getOrCreateInstance('#myAlert')
alert.close()

Nga huihuinga

Ko te mono matohi a Bootstrap e whakaatu ana i etahi huihuinga mo te hono ki te mahi mataara.

Takahanga Whakaahuatanga
close.bs.alert Ka ahi tonu ina closekarangahia te aratuka tauira.
closed.bs.alert I puhia ina katia te matohi ka mutu nga whakawhitinga CSS. 
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()
})
