JaavaScript

Bootstrap gara jireenyaatti fidaa filannoo JavaScript plugins keenyaan. Waa'ee tokkoon tokkoo pilaaginii, filannoowwan API deetaa fi sagantaa keenyaa fi kkf baradhu.

Fuula kana irratti

Dhuunfaa ykn qindaa’ee

Plugins dhuunfaan hammatamuu danda'u (Bootstrap's individual fayyadamuun js/dist/*.js), ykn hunda yeroo tokkotti fayyadamuun bootstrap.jsykn xiqqaate bootstrap.min.js(lamaanuu hin dabaliin).

Yoo bundler fayyadamte (Webpack, Parcel, Vite...), /js/dist/*.jsfaayiloota kanneen UMD qophaa'an fayyadamuu dandeessa.

Fayyadama unkaalee JaavaScript waliin

Bootstrap CSS framework kamiinuu fayyadamuun kan danda'amu yoo ta'u, Bootstrap JavaScript frameworks JavaScript akka React, Vue, fi Angular kanneen beekumsa guutuu DOM fudhatan waliin guutummaatti wal hin simne. Bootstrap fi framework lamaan isaanii elementii DOM walfakkaataa jijjiiruuf yaalu danda'u, bu'aan isaas dogongora akka dropdowns kan bakka “banaa” keessatti maxxanan fida.

Filannoon fooyya'aan warra gosa unkaalee kana fayyadamaniif bakka JaavaScript Bootstrap fayyadamuun paakeejii unkaa addaa fayyadamuudha . Filannoowwan baay'ee jaallataman keessaa muraasni kunooti:

Bootstrap akka moojuuliitti fayyadamuu

Ofii keetii yaalaa! Koodii madda fi demoo hojii Bootstrap akka moojuulii ES fayyadamuuf kuusaa twbs/examples irraa buufadhu . Akkasumas fakkeenya StackBlitz keessatti banuun ni danda'ama .

<script type="module">
  import { Toast } from 'bootstrap.esm.min.js'

</script>

JS bundlers wajjin wal bira qabamee yoo ilaalamu, ESM browser keessatti fayyadamuun maqaa moojulii osoo hin taane daandii guutuu fi maqaa faayilii fayyadamuu si gaafata. Waa'ee moojuulota JS biraawzari keessatti bal'inaan dubbisi. Kanaafidha 'bootstrap.esm.min.js'bakka 'bootstrap'olitti fayyadamnu. Haa ta'u malee, kun hirkattummaa Popper keenyaan daran walxaxaa ta'a, kunis Popper gara JavaScript keenyaatti akkasitti galcha:
