Beddel dulsaarka macnaha guud si aad u muujiso liisaska isku xidhka iyo in ka badan oo leh Bootstrap-ka hoos u dhaca.

Boggan

Dulmar

Hoosudhaca waa la rogi karaa, dulsaar macnaha guud ee muujinta liisaska isku xirka iyo wax ka badan. Waxa lagu sameeyay is dhexgal oo ay ku jiraan Bootstrap dropdown JavaScript plugin. Waxay ku rogaan gujisyada, ma aha inay dul heehaabayaan; kani waa go'aan naqshadayn ula kac ah .

Hoosudhaca waxaa lagu dhisay maktabad qolo saddexaad, Popper , taas oo bixisa meelayn firfircoon iyo ogaanshaha aragtida. Hubi inaad ku darto popper.min.js ka hor Bootstrap's JavaScript ama isticmaal bootstrap.bundle.min.js/ bootstrap.bundle.jska kooban Popper. Popper looma isticmaalo in lagu dhigo hoos-u-dhacyada navbars-ka inkasta oo meelaynta firfircooni aan loo baahnayn.

Helitaanka

Halbeegga WAI ARIA waxa uu qeexayaa role="menu"widget -ka dhabta ah , laakiin kani waxa uu gaar u yahay menu-yada codsiga u eg ee kiciya falalka ama hawlaha. Liiska ARIA waxa ka koobnaan kara oo keliya shayada menu-ka, shayga liiska sanduuqa, shayada badhanka raadiyaha, kooxaha badhanka raadiyaha, iyo menus-hoosaadka.

Bootstrap's dropdowns, dhanka kale, waxaa loo qaabeeyey inay noqdaan kuwo guud oo lagu dabaqi karo xaalado kala duwan iyo qaab-dhismeedka calaamadaynta. Tusaale ahaan, waxa suurtagal ah in la abuuro hoos u dhacyo ka kooban waxyaabo dheeraad ah iyo kontaroolada qaabaynta, sida goobaha wax laga raadiyo ama foomamka gelitaanka. Sababtan awgeed, Bootstrap ma filayo (ama si toos ah ugu darin) mid ka mid ah roleiyo aria-sifooyinka looga baahan yahay liiska ARIA ee runta ah. Qorayaashu waa inay ku daraan sifooyin gaar ah laftooda.

Si kastaba ha ahaatee, Bootstrap wuxuu ku daraa taageerada gudaha inta badan isdhexgalka menu-ka caadiga ah ee kiiboodhka, sida awoodda lagu dhex maro .dropdown-itemwalxaha shakhsi ahaaneed iyadoo la adeegsanayo furayaasha cursorka oo ku xidh liiska ESCfuraha.

Tusaalooyinka

Isku duub beddelka hoos u dhaca (badhankaaga ama xidhiidhka) iyo liiska hoos u dhaca ee gudaha .dropdown, ama shay kale oo sheegaya position: relative;. Hoos-u-dhac ayaa laga kicin karaa <a>ama <button>canaasiirta si ay si fiican ugu habboonaato baahiyahaaga suurtagalka ah. Tusaalooyinka halkan lagu muujiyey waxay isticmaalaan <ul>walxaha semantic halka ay ku habboon tahay, laakiin calaamadaynta caadada waa la taageeray.

Hal badhan

Mid kasta .btnwaxa loo rogi karaa beddelka hoos u dhaca oo leh waxoogaa isbeddello ah. Waa kuwan sida aad uga dhigi karto inay ku shaqeeyaan labada <button>shay:

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown button
  </button>
  <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>

Iyo <a>curiyayaasha:

<div class="dropdown">
  <a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown link
  </a>

  <ul class="dropdown-menu" aria-labelledby="dropdownMenuLink">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>

Qaybta ugu fiican ayaa ah inaad tan ku samayn karto badhan kasta oo kala duwan, sidoo kale:

<!-- Example single danger button -->
<div class="btn-group">
  <button type="button" class="btn btn-danger dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Action
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

Badhan kala jeex

Sidoo kale, samee badhanka kala qaybsan ee hoos u dhaca oo leh wax la mid ah kuwa hoos u dhaca badhanka, laakiin lagu daro .dropdown-toggle-splitkala dheeraynta saxda ah ee ku wareegsan daryeelka hoos u dhaca.

Waxaan u isticmaalnaa fasalkan dheeraadka ah si aan u dhimno jiifka paddinglabada dhinac ee daryeelka 25% oo aan ka saarno margin-leftwaxa lagu daray hoos u dhigista badhanka caadiga ah. Isbeddelladaas dheeriga ah waxay xannaanada ku hayaan badhanka kala qaybsan waxayna bixiyaan meel si habboon u cabbiran oo ku dheggan badhanka weyn.

<!-- Example split danger button -->
<div class="btn-group">
  <button type="button" class="btn btn-danger">Action</button>
  <button type="button" class="btn btn-danger dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

Cabbirka

Hoos-u-dhacyada badhanka waxay la shaqeeyaan badhamada cabbirrada oo dhan, oo ay ku jiraan kuwa caadiga ah iyo badhamada hoos u dhaca.

<!-- Large button groups (default and split) -->
<div class="btn-group">

Isticmaalka

Iyada oo loo marayo sifooyinka xogta ama JavaScript, plugin-ka hoos-u-dhaca wuxuu beddelaa nuxurka qarsoon ( menus hoos u dhaca ) isagoo ku rogaya .showfasalka waalidka .dropdown-menu. Sifada data-bs-toggle="dropdown"waxay ku tiirsan tahay xidhitaanka liiska hoos u dhaca ee heerka codsiga, markaa waa fikrad wanaagsan in had iyo jeer la isticmaalo.

Aaladaha la taabto, furista hoos u dhaca waxay ku daraa maamulayaal madhan mouseovercarruurta u dhow <body>curiyaha. Tani waxay qirtay jabsiga fool xun waa lagama maarmaan in ay ka shaqeeyaan agagaarka quirk ah ee iOS' waftiga dhacdo , taas oo haddii kale ka hortagi lahaa tuubada meel kasta oo ka baxsan hoos-u-dhicidda ka kiciya code in xidho hoos u dhaca ah. Marka hoos u dhigista la xiro, kuwan dheeraadka ah mouseoveree gacanta ku haya waa la saarayaa.

Iyada oo loo marayo sifooyinka xogta

Ku dar data-bs-toggle="dropdown"xiriiriye ama badhan si aad u beddesho hoos u dhaca.

<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">
    ...
  </ul>
</div>

Iyadoo loo marayo JavaScript

Hoos ka wac JavaScript:

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

Iyadoo aan loo eegin haddii aad ugu wacdo hoos u dhigistaada JavaScript ama aad isticmaasho xogta-api, data-bs-toggle="dropdown"had iyo jeer waxaa looga baahan yahay inaad ku jirto qaybta kicinta ee hoos u dhaca.

Ikhtiyaarada

Ikhtiyaarada waxaa lagu gudbi karaa sifada xogta ama JavaScript. Sifooyinka xogta, ku dheji magaca ikhtiyaarka data-bs-, sida ku jira data-bs-offset="". Hubi inaad ka beddesho nooca kiiska ee magaca ikhtiyaarka ah ee geela una beddelo kiis kebab marka aad doorashooyinka ku gudbinayso sifooyinka xogta. Tusaale ahaan, halkii aad isticmaali lahayd data-bs-autoClose="false", isticmaal data-bs-auto-close="false".

Magaca Nooca Asal ahaan Sharaxaada
boundary xadhig | curiye 'clippingParents' Xadka xad-dhaafka xad-dhaafka ah ee liiska liiska hoos-u-dhaca (waxay qusaysaa oo keliya wax ka beddelka Popper ka-hortagga qulqulka). Sida caadiga ah waa 'clippingParents'oo aqbali kartaa tixraaca HTMLElement (iyada oo loo marayo JavaScript kaliya). Wixii macluumaad dheeraad ah tixraac Popper's detectOverflow docs .
reference xadhig | element | walax 'toggle' Cunsurka tixraaca ee liiska hoos u dhaca. Aqbala qiyamka 'toggle', 'parent', tixraaca HTMLElement ama shay bixinta getBoundingClientRect. Macluumaad intaas ka badan ka eeg dukumeentiyada wax dhisaha ee Popper iyo dukumeentiyada element-ka ah .
display xadhig 'dynamic' Sida caadiga ah, waxaan u isticmaalnaa Popper meelaynta firfircoon. Ku dami tan static.
offset array | xadhig | shaqayn [0, 2]

Deminta hoos u dhaca marka loo eego bartilmaameedkiisa. Waxaad ku gudbin kartaa xarkaha xogta sifooyin leh qiyam kala soocan sida:data-bs-offset="10,20"

Marka hawl loo isticmaalo in lagu go'aamiyo dhimista, waxa loogu yeedhaa shay ka kooban meelaynta popper, tixraaca, iyo popper rects sida doodiisa kowaad. Xubinta kicinta ee DOM node waxa loo gudbiyaa sidii doodda labaad. Shaqadu waa inay soo celisaa array leh laba lambar: .[skidding, distance]

Macluumaad dheeraad ah ka eeg dukumeentiyada dhimista ee Popper .
autoClose booliyan | xadhig true

Habee hab-dhaqanka isu-dhowaanshaha tooska ah ee hoos u dhaca:

  • true- hoos u dhigista waa la xidhi doonaa adigoo gujinaya dibadda ama gudaha liiska hoos u dhaca.
  • false- Hoosudhaca waa la xidhi doonaa adigoo gujinaya badhanka beddelka oo gacanta ku wac hideama togglehabka. (Sidoo kale ma xiri doono adigoo riixaya escfuraha)
  • 'inside'- Hoos-u-dhigga waa la xidhi doonaa (kaliya) adigoo gujinaya gudaha liiska hoos u dhaca.
  • 'outside'- Hoosudhaca waa la xidhi doonaa (kaliya) adigoo gujinaya meel ka baxsan liiska hoos u dhaca.
popperConfig waxba | shay | shaqayn null

Si aad u bedesho Bootstrap's default Popper config, arag qaabka Popper's .
