Txheej txheem cej luam

Tus kheej los yog muab tso ua ke

Plugins tuaj yeem suav nrog tus kheej (siv Bootstrap tus kheej *.jscov ntaub ntawv), lossis tag nrho ib zaug (siv bootstrap.jslossis cov minified bootstrap.min.js).

Cov ntaub ntawv yam ntxwv

Koj tuaj yeem siv tag nrho Bootstrap plugins nkaus xwb los ntawm markup API yam tsis tau sau ib kab ntawm JavaScript. Qhov no yog Bootstrap's first-class API thiab yuav tsum yog koj thawj qhov kev txiav txim siab thaum siv lub plugin.

Uas tau hais tias, hauv qee qhov xwm txheej nws yuav tsim nyog los tua qhov kev ua haujlwm no. Yog li ntawd, peb kuj muab lub peev xwm los lov tes taw cov ntaub ntawv attribute API los ntawm unbinding tag nrho cov txheej xwm ntawm cov ntaub ntawv namespaced nrog data-api. Qhov no zoo li no:

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

Xwb, txhawm rau tsom ib lub plugin tshwj xeeb, tsuas yog suav nrog lub plugin lub npe ua lub npe chaw nrog rau cov ntaub ntawv-api namespace zoo li no:

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

Programmatic API

Peb kuj ntseeg tias koj yuav tsum tuaj yeem siv tag nrho Bootstrap plugins nkaus xwb los ntawm JavaScript API. Tag nrho cov pej xeem APIs yog ib leeg, chainable txoj kev, thiab xa rov qab cov sau ua raws li.

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

Txhua txoj hauv kev yuav tsum lees txais qhov kev xaiv xaiv khoom, ib txoj hlua uas tsom rau ib txoj hauv kev, lossis tsis muaj dab tsi (uas pib lub plugin nrog tus cwj pwm tsis zoo):

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

Txhua lub plugin kuj nthuav tawm nws cov neeg tsim khoom nyoos ntawm cov Constructorcuab yeej: $.fn.popover.Constructor. Yog tias koj xav tau ib qho plugin tshwj xeeb, muab nws ncaj qha los ntawm lub caij: $('[rel="popover"]').data('popover').

Default settings

Koj tuaj yeem hloov qhov chaw pib rau lub plugin los ntawm kev hloov kho lub plugin cov Constructor.DEFAULTSkhoom:

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

Tsis muaj teeb meem

Qee lub sij hawm nws yog qhov tsim nyog los siv Bootstrap plugins nrog rau lwm qhov UI lub luag haujlwm. Hauv cov xwm txheej no, kev sib tsoo ntawm lub npe chaw tuaj yeem tshwm sim qee zaus. Yog tias qhov no tshwm sim, koj tuaj yeem hu .noConflictrau lub plugin koj xav rov qab tus nqi ntawm.

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

Cov xwm txheej

Bootstrap muab cov xwm txheej kev cai rau feem ntau plugins 'kev ua tshwj xeeb. Feem ntau, cov no tuaj nyob rau hauv ib daim ntawv infinitive thiab yav dhau los koom nrog - qhov twg qhov infinitive (ex. show) yog tshwm sim thaum pib ntawm ib qho kev tshwm sim, thiab nws yav dhau los kev koom tes (ex. shown) yog tshwm sim ntawm qhov ua tiav ntawm qhov kev txiav txim.

Raws li ntawm 3.0.0, tag nrho cov txheej xwm Bootstrap yog namespaced.

Tag nrho cov txheej xwm infinitive muab preventDefaultfunctionality. Qhov no muab lub peev xwm los nres qhov kev txiav txim ua ntej nws pib.

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

Tshuaj ntxuav tes

Cov lus qhia thiab Popovers siv peb cov tshuaj ntxuav tes ua ke los ntxuav cov kev xaiv uas lees txais HTML.

Tus whiteListnqi pib yog cov hauv qab no:

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', 'alt', 'title', 'width', 'height'],
  li: [],
  ol: [],
  p: [],
  pre: [],
  s: [],
  small: [],
  span: [],
  sub: [],
  sup: [],
  strong: [],
  u: [],
  ul: []
}

Yog tias koj xav ntxiv qhov tseem ceeb tshiab rau lub neej ntawd whiteListkoj tuaj yeem ua cov hauv qab no:

var myDefaultWhiteList = $.fn.tooltip.Constructor.DEFAULTS.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)

Yog tias koj xav hla peb cov tshuaj tua kab mob vim tias koj nyiam siv lub tsev qiv ntawv tshwj xeeb, piv txwv li DOMPurify , koj yuav tsum ua cov hauv qab no:

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

Cov lej

Cov version ntawm txhua qhov ntawm Bootstrap's jQuery plugins tuaj yeem nkag tau los ntawm cov VERSIONcuab yeej ntawm plugin tus tsim. Piv txwv li, rau tooltip plugin:

$.fn.tooltip.Constructor.VERSION // => "3.4.1"

Tsis muaj qhov cuam tshuam tshwj xeeb thaum JavaScript raug kaw

Bootstrap's plugins tsis poob rov qab tshwj xeeb zoo nkauj thaum JavaScript raug kaw. Yog tias koj mob siab txog cov neeg siv kev paub dhau los hauv qhov no, siv <noscript>los piav qhia qhov xwm txheej (thiab yuav ua li cas rov qhib JavaScript) rau koj cov neeg siv, thiab / lossis ntxiv koj tus kheej cov kev cai poob qis.

Kev hloov pauv hloov pauv.js

Hais txog kev hloov

Rau kev hloov pauv yooj yim, suav nrog transition.jsib zaug nrog rau lwm cov ntaub ntawv JS. Yog tias koj siv cov ntawv sau ua ke (lossis me me) bootstrap.js, tsis tas yuav suav nrog qhov no - nws twb muaj lawm.

Dab tsi nyob hauv

Transition.js yog tus pab cuam yooj yim rau transitionEndcov xwm txheej nrog rau CSS kev hloov pauv emulator. Nws tau siv los ntawm lwm cov plugins los kuaj xyuas CSS kev hloov pauv kev txhawb nqa thiab txhawm rau ntes dai hloov pauv.

Disabling kev hloov

Kev hloov pauv tuaj yeem cuam tshuam thoob ntiaj teb siv cov lus piav qhia JavaScript hauv qab no, uas yuav tsum tuaj tom qab transition.js(lossis bootstrap.js, bootstrap.min.jsraws li qhov xwm txheej) tau thauj khoom:

$.support.transition = false

Modals modal.js

Modals yog streamlined, tab sis saj zawg zog, dialog prompts nrog yam tsawg kawg nkaus yuav tsum tau functionality thiab ntse defaults.

Vim li cas HTML5 txhais nws cov semantics, autofocusHTML tus cwj pwm tsis muaj txiaj ntsig hauv Bootstrap modals. Txhawm rau ua tiav cov txiaj ntsig zoo ib yam, siv qee qhov kev cai JavaScript:

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').focus()
})

Piv txwv

Piv txwv li

Ib tug rendered modal nrog header, lub cev, thiab txheej ntawm kev ua nyob rau hauv lub footer.
