Ikoreshwa

Binyuze muri data ibiranga cyangwa JavaScript, plugin yamanutse ihindura ibintu byihishe (ibimanuka byamanutse) uhinduranya .showishuri kubabyeyi .dropdown-menu. Ikiranga data-bs-toggle="dropdown"gishingiye ku gufunga ibimanuka kurutonde rwa porogaramu, nibyiza rero guhora tuyikoresha.

Kubikoresho bifasha gukoraho, gufungura ibitonyanga byongeramo ibikoresho byubusa mouseoverkubana bahita ba <body>element. Ibi byemewe ko ari hack birakenewe kugirango dukore hafi yikinamico mu ntumwa za iOS , ibyo bikaba byabuza gukanda ahantu hose hanze y’igitonyanga gukurura code ifunga ibitonyanga. Iyo ibitonyanga bimaze gufungwa, ibyo byongeweho ubusa mouseoverbikurwaho.

Binyuze mu biranga amakuru

Ongeraho data-bs-toggle="dropdown"kumurongo cyangwa buto kugirango uhindure ibitonyanga.

<div class="dropdown">
  <button id="dLabel" type="button" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown trigger
  </button>
  <ul class="dropdown-menu" aria-labelledby="dLabel">

var dropdownElementList = [].slice.call(document.querySelectorAll('.dropdown-toggle'))
var dropdownList = dropdownElementList.map(function (dropdownToggleEl) {
  return new bootstrap.Dropdown(dropdownToggleEl)
})
data-bs-toggle="dropdown"biracyasabwa

Utitaye ko wahamagaye ibitonyanga ukoresheje JavaScript cyangwa ugakoresha data-api, data-bs-toggle="dropdown"burigihe birasabwa kuba uhari kubintu byamanutse.

Amahitamo

Amahitamo arashobora kunyuzwa kumurongo wamakuru cyangwa JavaScript. Kubiranga Ibyatanzwe, Ongeraho Ihitamo Izina Kuri data-bs-, Nka Muri data-bs-offset="". Witondere guhindura ubwoko bwurubanza rwamazina kuva kuri camelCase kuri kebab-urubanza mugihe utambutsa amahitamo ukoresheje ibiranga amakuru. Kurugero, aho gukoresha data-bs-autoClose="false", koresha data-bs-auto-close="false".

Izina Andika Mburabuzi Ibisobanuro
boundary umugozi | element 'clippingParents' Kurenga imipaka ntarengwa ya menu yamanutse (ikoreshwa gusa kuri popper yo gukumiraOverflow modifier). Mubusanzwe ni 'clippingParents'kandi irashobora kwemera HTMLElement (ukoresheje JavaScript gusa). Kubindi bisobanuro reba popper's detectOverflow docs .
reference umugozi | ikintu | ikintu 'toggle' Ibikoresho byerekana ibintu byamanutse. Emera indangagaciro za 'toggle',, 'parent'HTMLElement yerekanwe cyangwa ikintu gitanga getBoundingClientRect. Kubindi bisobanuro reba popper yubaka docs hamwe nibintu bisanzwe .
display umugozi 'dynamic' Mburabuzi, dukoresha Popper kumwanya uhagaze. Hagarika ibi hamwe static.
offset array | umugozi | imikorere [0, 2]

Kureka kugabanuka ugereranije nintego yayo. Urashobora gutambutsa umurongo muri data ibiranga hamwe na koma yatandukanijwe indangagaciro nka:data-bs-offset="10,20"

Iyo imikorere ikoreshwa mukumenya offset, yitwa hamwe nikintu kirimo icyerekezo cya popper, icyerekezo, hamwe na popper ikosora nkibitekerezo byayo byambere. Ikintu gikurura DOM node yatambutse nkimpaka ya kabiri. Igikorwa kigomba gusubiza umurongo hamwe nimibare ibiri : .[skidding, distance]

Kubindi bisobanuro reba kuri popper ya offset .
autoClose boolean | umugozi true

Hindura ibinyabiziga bifunga imyitwarire yamanuka:

  • true- ibitonyanga bizafungwa ukanze hanze cyangwa imbere muri menu yamanutse.
