Bring Bootstrap to layf wit wi opshɔnal JavaSkript plɔgin dɛn we dɛn bil pan jQuery. Lan bɔt ɛni plɔgin, wi data ɛn programmatik API opshɔn dɛn, ɛn ɔda tin dɛn.

Wan wan ɔ we dɛn dɔn kɔmpilayt

Plɔgin dɛn kin inklud wan wan (yuz Bootstrap in wan wan js/dist/*.js), ɔ ɔl wan tɛm yuz bootstrap.jsɔ di minified bootstrap.min.js(nɔ inklud ɔl tu).

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

Ɔl di we dɛn fɔ aksept wan opshɔnal opshɔn ɔbjɛkt, wan string we de tɔch wan patikyula we, ɔ natin (we de bigin wan plɔgin wit difɔlt bihayvya):

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

Ɛni plɔgin de ɛksplɔz in raw kɔnstrɔkta bak pan wan Constructorprɔpati: $.fn.popover.Constructor. If yu want fɔ gɛt wan patikyula plɔgin instans, tek am dairekt frɔm wan ɛlimɛnt: $('[rel="popover"]').data('popover').

Asynchronous fכnshכn dεm εn transishכn dεm

Ɔl di programmatik API mɛtɔd dɛn na asynchronous ɛn dɛn kin kam bak to di pɔsin we kɔl wans di transishɔn dɔn stat bɔt bifo i dɔn .

Fɔ mek yu ebul fɔ du wan akshɔn wans di chenj dɔn, yu kin lisin to di kɔrɛspɔndɛns ivin.

  $('#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 !!
