Javascript

Aumai Bootstrap i le ola ma a matou filifiliga JavaScript plugins fausia i luga o le jQuery. A'oa'o e uiga i mea fa'apipi'i ta'itasi, a matou fa'amaumauga ma polokalame API filifiliga, ma isi mea.

Ta'ito'atasi pe tuufaatasia

E mafai ona fa'apipi'i fa'apipi'i ta'ito'atasi (fa'aaogā le tagata ta'ito'atasi a Bootstrap js/dist/*.js), po'o fa'aaoga uma i le taimi e tasi bootstrap.jspo'o le fa'aitiitiga bootstrap.min.js(aua le aofia uma).

Afai e te faʻaogaina se fusi (Webpack, Rollup…), e mafai ona e faʻaogaina /js/dist/*.jsfaila ua saunia UMD.

Fa'alagolago

O nisi fa'apipi'i ma vaega CSS fa'alagolago i isi fa'apipi'i. Afai e te faʻapipiʻi faʻapipiʻi taʻitasi, ia mautinoa e siaki mo nei faʻalagolago i le docs. Ia maitauina foi o plugini uma e faalagolago i le jQuery (o lona uiga e tatau ona aofia ai le jQuery i luma o faila faila). Fa'afeso'ota'i matoupackage.json e va'ai po'o fea fa'aliliuga o le jQuery e lagolagoina.

E fa'alagolago fo'i a matou pa'u, popovers ma meafaigaluega i Popper.js .

Uiga fa'amaumauga

Toeitiiti lava o Bootstrap plugins e mafai ona faʻaogaina ma faʻapipiʻi e ala ile HTML naʻo faʻatasi ai ma faʻamatalaga uiga (o la tatou auala sili e faʻaogaina ai le JavaScript). Ia mautinoa e naʻo le tasi le seti o faʻamatalaga uiga i luga o se elemene e tasi (faʻataʻitaʻiga, e le mafai ona e faʻaosoina se meafaigaluega ma auala mai le ki lava e tasi.)

Ae ui i lea, i nisi tulaga atonu e manaʻomia le tapeina o lenei gaioiga. Ina ia fa'agata le API fa'amaumauga, tatala uma mea na tutupu i luga o le pepa fa'ailoga igoa data-apifa'apea:

$(document).off('.data-api')

I le isi itu, e faʻatatau i se mea faʻapipiʻi faʻapitoa, naʻo le faʻapipiʻiina o le igoa ole plugin o se igoa avanoa faʻatasi ai ma le data-api namespace pei o lenei:

$(document).off('.alert.data-api')

Mea na tutupu

O le Bootstrap e tuʻuina atu mea faʻapitoa mo le tele o mea faʻapitoa a plugins. E masani lava, o nei mea e sau i se fa'ailoga fa'apitoa ma le taimi ua tuana'i - lea e fa'aosoina ai le infinitive (ex. show) i le amataga o se mea na tupu, ma lona fa'ailoga participle ua mavae (ex. shown) e fa'aosoina pe a mae'a se gaioiga.

O mea fa'apitoa uma e maua ai preventDefault()galuega fa'atino. O lenei mea e maua ai le malosi e taofi ai le faʻatinoina o se gaioiga aʻo leʻi amataina. O le toe fa'afo'i sese mai se tagata e fa'atino mea na tupu e otometi fo'i ona vala'au preventDefault().

$('#myModal').on('show.bs.modal', function (event) {
  if (!data) {
    return event.preventDefault() // stops modal from being shown
  }
})

API polokalame

Matou te talitonu foi e tatau ona e faʻaogaina uma Bootstrap plugins mama e ala i le JavaScript API. O API fa'alaua'itele uma e tasi, auala e mafai ona filifili, ma toe fa'afo'i le aoina na fa'atino.

$('.btn.danger').button('toggle').addClass('fat')

O metotia uma e tatau ona talia se mea e filifili ai filifiliga, se manoa e faʻatatau i se metotia faʻapitoa, poʻo leai se mea (lea e amataina ai se faʻapipiʻi ma amioga le lelei):

$('#myModal').modal() // initialized with defaults
$('#myModal').modal({ keyboard: false }) // initialized with no keyboard
$('#myModal').modal('show') // initializes and invokes show immediately

E fa'aalia fo'i e fa'apipi'i ta'itasi lona faufale mata'utia i luga o se Constructormeatotino: $.fn.popover.Constructor. Afai e te manaʻo e maua se faʻataʻitaʻiga faʻapitoa faʻapipiʻi, aumai saʻo mai se elemene: $('[rel="popover"]').data('popover').

Gaioiga asynchronous ma suiga

O metotia API fa'apolokalame uma e le fetaui ma toe fo'i i le tagata vala'au pe a amata le suiga ae le'i uma .

Ina ia mafai ona faʻatino se gaioiga pe a maeʻa le suiga, e mafai ona e faʻalogo i le mea na tupu.

$('#myCollapse').on('shown.bs.collapse', function (event) {
  // Action to execute once the collapsible area is expanded
})

E le gata i lea, o le a le amana'ia se auala e valaau ai i se vaega o suiga .

$('#myCarousel').on('slid.bs.carousel', function (event) {
  $('#myCarousel').carousel('2') // Will slide to the slide 2 as soon as the transition to slide 1 is finished
})

$('#myCarousel').carousel('1') // Will start sliding to the slide 1 and returns to the caller
$('#myCarousel').carousel('2') // !! Will be ignored, as the transition to the slide 1 is not finished !!

Fa'atonuga

E mafai ona e suia tulaga fa'aletonu mo se fa'apipi'i e ala i le suia o le Constructor.Defaultmea fa'apipi'i:

// changes default for the modal plugin's `keyboard` option to false
$.fn.modal.Constructor.Default.keyboard = false

Leai se feteenaiga

O nisi taimi e manaʻomia le faʻaogaina o Bootstrap plugins ma isi faʻavae UI. I ia tulaga, e mafai ona tupu i nisi taimi le fete'ena'iga o igoa. Afai e tupu lenei mea, e mafai ona e valaʻau .noConflicti le plugin e te manaʻo e toe faʻafoʻi le tau o.

var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality

Numera fa'aliliuga

E mafai ona maua le fa'asologa o mea ta'itasi a Bootstrap's jQuery plugins e ala i le VERSIONmeatotino a le faufale o le plugin. Mo se faʻataʻitaʻiga, mo le meafaigaluega faʻapipiʻi:

$.fn.tooltip.Constructor.VERSION // => "4.6.2"

Leai ni fa'aletonu fa'apitoa pe a fa'aletonu le JavaScript

O plugini a Bootstrap e le toe fo'i fa'apitoa pe a fa'aletonu le JavaScript. Afai e te popole e uiga i le tagata faʻaoga i lenei tulaga, faʻaaoga <noscript>e faʻamatala ai le tulaga (ma pe faʻafefea ona toe faʻaogaina le JavaScript) i au tagata faʻaoga, ma / pe faʻaopoopo au lava faʻaleaga masani.

Util

O faila JavaScript uma a Bootstrap e faʻalagolago i util.jsai ma e tatau ona aofia ai faʻatasi ma isi faila JavaScript. Afai o loʻo e faʻaaogaina le tuʻufaʻatasia (poʻo le faʻaititia) bootstrap.js, e leai se manaʻoga e aofia ai lenei mea-ua uma ona iai.

util.jse aofia ai galuega aoga ma se fesoasoani autu mo transitionEndmea e tutupu faʻapea foʻi ma le CSS transition emulator. O lo'o fa'aogaina e isi fa'apipi'i e siaki ai le lagolago mo suiga o le CSS ma pu'e fa'aoga fa'atautau.

Sanitizer

Tooltips ma Popovers e fa'aogaina le matou fa'amama fa'afale e fa'amama ai filifiliga e talia HTML.

O le tau fa'aletonu whiteListo mea nei:

var ARIA_ATTRIBUTE_PATTERN = /^aria-[\w-]*$/i
var DefaultWhitelist = {
  // Global attributes allowed on any supplied element below.
  '*': ['class', 'dir', 'id', 'lang', 'role', ARIA_ATTRIBUTE_PATTERN],
  a: ['target', 'href', 'title', 'rel'],
  area: [],
  b: [],
  br: [],
  col: [],
  code: [],
  div: [],
  em: [],
  hr: [],
  h1: [],
  h2: [],
  h3: [],
  h4: [],
  h5: [],
  h6: [],
  i: [],
  img: ['src', 'srcset', 'alt', 'title', 'width', 'height'],
  li: [],
  ol: [],
  p: [],
  pre: [],
  s: [],
  small: [],
  span: [],
  sub: [],
  sup: [],
  strong: [],
  u: [],
  ul: []
}

Afai e te manaʻo e faʻaopoopo ni tau fou i lenei faaletonu whiteListe mafai ona e faia mea nei:

var myDefaultWhiteList = $.fn.tooltip.Constructor.Default.whiteList

// To allow table elements
myDefaultWhiteList.table = []

// To allow td elements and data-option attributes on td elements
myDefaultWhiteList.td = ['data-option']

// You can push your custom regex to validate your attributes.
// Be careful about your regular expressions being too lax
var myCustomRegex = /^data-my-app-[\w-]+/
myDefaultWhiteList['*'].push(myCustomRegex)

Afai e te manaʻo e faʻamalo le matou sanitizer ona e te manaʻo e faʻaoga se faletusi faʻapitoa, mo se faʻataʻitaʻiga DOMpurify , e tatau ona e faia mea nei:

$('#yourTooltip').tooltip({
  sanitizeFn: function (content) {
    return DOMPurify.sanitize(content)
  }
})
