Spinners

Léirigh staid luchtaithe comhpháirte nó leathanaigh le rothlóirí Bootstrap, tógtha go hiomlán le HTML, CSS, agus gan JavaScript.

Faoi

Is féidir “sreangóirí” Bootstrap a úsáid chun staid luchtaithe do thionscadail a thaispeáint. Níl siad tógtha ach le HTML agus CSS, rud a chiallaíonn nach bhfuil JavaScript ag teastáil uait chun iad a chruthú. Beidh roinnt JavaScript saincheaptha uait, áfach, chun a n-infheictheacht a scoránaigh. Is féidir a gcuma, a ailíniú, agus a méid a shaincheapadh go héasca lenár ranganna fóntais iontacha.

Chun críocha inrochtaineachta, cuimsíonn gach lódóir anseo role="status"agus nead <span class="visually-hidden">Loading...</span>.

Tá éifeacht beochana an chomhpháirt seo ag brath ar prefers-reduced-motioncheist na meán. Féach an rannán tairiscint laghdaithe dár gcáipéisíocht inrochtaineachta .

Rothaí teorann

Bain úsáid as na rothlóirí teorann le haghaidh táscaire luchtaithe éadrom.

html

<div class="spinner-border" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Dathanna

Úsáideann an rothlóir teorann currentColordá chuid border-color, rud a chiallaíonn gur féidir leat an dath a shaincheapadh le fóntais datha téacs . Is féidir leat aon cheann dár bhfóntais datha téacs a úsáid ar an rothlóir caighdeánach.

html

<div class="spinner-border text-primary" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-secondary" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-success" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-danger" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-warning" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-info" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-light" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-dark" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Cén fáth nach n-úsáideann tú border-colorfóntais? Sonraíonn gach rothlóir transparentteorann teorainn le haghaidh taobh amháin ar a laghad, agus mar sin .border-{color}sháródh fóntais é sin.

spinner ag fás

Mura bhfuil fonn ort rothlóir teorann, aistrigh chuig an rothlóir fáis. Cé nach n-iompaíonn sé go teicniúil, fásann sé arís agus arís eile!

html

<div class="spinner-grow" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Arís eile, tógtar an rothlóir seo le currentColor, ionas gur féidir leat a chuma a athrú go héasca le fóntais dath téacs . Anseo tá sé i gorm, chomh maith leis na leaganacha tacaithe.

html

<div class="spinner-grow text-primary" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-secondary" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-success" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-danger" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-warning" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-info" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-light" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-dark" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Ailíniú

Tógtar rothlóirí i Bootstrap le rems , currentColor, agus display: inline-flex. Ciallaíonn sé seo gur féidir iad a athrú go héasca, a dhathú agus a ailíniú go tapa.

Imeall

Bain úsáid as fóntais corrlaigh mar .m-5spásáil éasca.

html

<div class="spinner-border m-5" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Socrúchán

Úsáid fóntais flexbox , fóntais snámhphointe , nó fóntais ailínithe téacs chun rothlóirí a chur go díreach san áit a dteastaíonn uait iad in aon chás.

Flex

html

<div class="d-flex justify-content-center">
  <div class="spinner-border" role="status">
    <span class="visually-hidden">Loading...</span>
  </div>
</div>

html

<div class="clearfix">
  <div class="spinner-border float-end" role="status">

</div>

Ailíniú téacs

html

<div class="text-center">
  <div class="spinner-border" role="status">
    <span class="visually-hidden">Loading...</span>
  </div>
</div>

Méid

Cuir leis .spinner-border-smagus .spinner-grow-smchun rothlóir níos lú a dhéanamh ar féidir é a úsáid go tapa laistigh de chomhpháirteanna eile.

html

<div class="spinner-border spinner-border-sm" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow spinner-grow-sm" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Nó, bain úsáid as CSS saincheaptha nó stíleanna inlíne chun na toisí a athrú de réir mar is gá.

html

<div class="spinner-border" style="width: 3rem; height: 3rem;" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow" style="width: 3rem; height: 3rem;" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Cnaipí

Úsáid rothlóirí laistigh de chnaipí chun a chur in iúl go bhfuil gníomh á phróiseáil nó ar siúl faoi láthair. Is féidir leat freisin an téacs a mhalartú amach as an eilimint rothlaithe agus úsáid a bhaint as téacs cnaipe de réir mar is gá.

html

<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
  <span class="visually-hidden">Loading...</span>
</button>
<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
  Loading...
</button>

html

<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-grow spinner-grow-sm" role="status" aria-hidden="true"></span>
  <span class="visually-hidden">Loading...</span>
</button>
<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-grow spinner-grow-sm" role="status" aria-hidden="true"></span>
  Loading...
</button>

CSS

Athróga

Curtha leis in v5.2.0

Mar chuid de chur chuige athróg CSS Bootstrap atá ag teacht chun cinn, úsáideann rothlóirí athróga áitiúla CSS anois ar .spinner-borderagus .spinner-growle haghaidh saincheaptha feabhsaithe fíor-ama. Socraítear luachanna na n-athróg CSS trí Sass, mar sin tacaítear le saincheaptha Sass fós freisin.

Athróga rothlóra teorann:

  --#{$prefix}spinner-width: #{$spinner-width};
  --#{$prefix}spinner-height: #{$spinner-height};
  --#{$prefix}spinner-vertical-align: #{$spinner-vertical-align};
  --#{$prefix}spinner-border-width: #{$spinner-border-width};
  --#{$prefix}spinner-animation-speed: #{$spinner-animation-speed};
  --#{$prefix}spinner-animation-name: spinner-border;

Athróga spinner atá ag fás:

  --#{$prefix}spinner-width: #{$spinner-width};
  --#{$prefix}spinner-height: #{$spinner-height};
  --#{$prefix}spinner-vertical-align: #{$spinner-vertical-align};
  --#{$prefix}spinner-animation-speed: #{$spinner-animation-speed};
  --#{$prefix}spinner-animation-name: spinner-grow;

I gcás an dá rothlóir, úsáidtear ranganna mionathraithe rothlóra chun luachanna na n-athróg CSS seo a nuashonrú de réir mar is gá. Mar shampla, .spinner-border-smdéanann an rang an méid seo a leanas:

  --#{$prefix}spinner-width: #{$spinner-width-sm};
  --#{$prefix}spinner-height: #{$spinner-height-sm};
  --#{$prefix}spinner-border-width: #{$spinner-border-width-sm};

Athróga Sass

$spinner-width:           2rem;
$spinner-height:          $spinner-width;
$spinner-vertical-align:  -.125em;
$spinner-border-width:    .25em;
$spinner-animation-speed: .75s;

$spinner-width-sm:        1rem;
$spinner-height-sm:       $spinner-width-sm;
$spinner-border-width-sm: .2em;

Frámaí eochair

Úsáidte chun beochan CSS a chruthú dár rothlóirí. San áireamh i scss/_spinners.scss.

@keyframes spinner-border {
  to { transform: rotate(360deg) #{"/* rtl:ignore */"}; }
}

@keyframes spinner-grow {
  0% {
    transform: scale(0);
  }
  50% {
    opacity: 1;
    transform: none;
  }
}
