Aw k’a kɔlɔsi fana ko plugins bɛɛ bɛ tali kɛ jQuery de la (o kɔrɔ ye ko jQuery ka kan ka don a kɔnɔ ka kɔn plugin files ɲɛ). Aw ye anw lajɛpackage.json walasa k’a dɔn jQuery bɔko minnu bɛ dɛmɛ.

An ka dropdowns, popovers ani baarakɛminɛnw fana bɛ bɔ Popper.js de la.

Donanw ka fɛnw

Bootstrap 'kɔnɔfɛnw bɛɛ bɛ Se ka Dabɔ ani k'u Labɛn HTML dɔrɔn fɛ ni data attributes (an ka JavaScript baarakɛcogo ɲuman ye). Aw ye aw jija ka baara kɛ ni kunnafoni-falen-falen-yɔrɔ kelen dɔrɔn ye fɛn kelen kan (misali la, aw tɛ se ka baarakɛminɛnw ni modɛli dɔ daminɛ ka bɔ butɔni kelen na.)

})

API porogaramulen

An dalen b’a la fana ko i ka kan ka se ka baara kɛ ni Bootstrap plugins bɛɛ ye JavaScript API dɔrɔn fɛ. Foroba APIw bɛɛ ye fɛɛrɛ kelenw ye, minnu bɛ se ka siri ni cakɛda ye, ani ka segin dalajɛlen kan min waleyara.

Plugin kelen-kelen bɛɛ fana b’a ka raw constructor jira Constructornafolo dɔ kan: $.fn.popover.Constructor. N’i ​​b’a fɛ ka plugin instance kɛrɛnkɛrɛnnen dɔ sɔrɔ, i k’a sɔrɔ k’a ɲɛsin element dɔ ma: $('[rel="popover"]').data('popover').

Fallback kɛrɛnkɛrɛnnen si tɛ yen ni JavaScript ma baara kɛ

Bootstrap ka plugins tɛ bin kɔfɛ kɛrɛnkɛrɛnnenya la gracefully ni JavaScript bɛ baara la.

A whiteListnafa fɔlɔ ye nin ye:
