Navs
Amaxwebhu kunye nemizekelo yendlela yokusebenzisa i-Bootstrap equkiweyo yezinto zokukhangela.
Ukukhangela kuyafumaneka kwiBootstrap yabelana ngokuphawulwa ngokubanzi kunye nezimbo, ukusuka kwisiseko .nav
seklasi ukuya kumazwe asebenzayo kunye nabakhubazekileyo. Tshintsha iiklasi zesilungisi ukutshintsha phakathi kwesimbo ngasinye.
Icandelo lesiseko .nav
lakhiwe nge-flexbox kwaye libonelela ngesiseko esomeleleyo sokwakha zonke iintlobo zezixhobo zokuhamba. Ibandakanya ezinye iindlela zokubhala ngaphezulu (zokusebenza ngezintlu), ezinye iikhonkco zekhonkco kwiindawo ezinkulu ezibethayo, kunye nesimbo esisisiseko sabakhubazekileyo.
Icandelo lesiseko .nav
alibandakanyi naliphi na .active
ilizwe. Le mizekelo ilandelayo ibandakanya iklasi, ikakhulu ukubonisa ukuba le klasi ayiqalisi nasiphi na isimbo esikhethekileyo.
Iiklasi zisetyenziswa kulo lonke, ngoko uphawu lwakho lunokuba bhetyebhetye kakhulu. Sebenzisa <ul>
s like ngasentla, okanye roll eyakho nge say <nav>
element. Kuba .nav
usebenziso display: flex
, amakhonkco e-nav aziphatha ngendlela efanayo nav izinto eziya kwenza, kodwa ngaphandle kophawulo olongezelelweyo.
Tshintsha isimbo .nav
s icandelo kunye modifiers kunye eziluncedo. Xuba kwaye utshatise njengoko kufuneka, okanye uzakhele eyakho.
Guqula ulungelelwaniso oluthe tye lwe nav yakho ngezixhobo ze flexbox . Ngokungagqibekanga, ii-navs zilungelelaniswe ekhohlo, kodwa unokuzitshintsha ngokulula zibesembindini okanye zilungelelaniswe ekunene.
Isembindini nge .justify-content-center
:
Ilungelelaniswe ekunene ne .justify-content-end
:
Gcina ukukhangela kwakho ngokutshintsha isikhokelo sento eguqukayo kunye nezinto .flex-column
eziluncedo. Ngaba kufuneka uzibeke kwezinye iindawo zokujonga kodwa hayi kwezinye? Sebenzisa iinguqulelo eziphendulayo (umz., .flex-sm-column
).
Njengesiqhelo, ukukhangela ngokuthe nkqo kunokwenzeka ngaphandle kwe <ul>
-s, kwakhona.
Ithatha i-nav esisiseko ukusuka phezulu kwaye yongeza .nav-tabs
iklasi ukuvelisa ujongano olunesithuba. Zisebenzise ukwenza imimandla enokwenzeka ngethebhu yethu iplagi yeJavaScript .
Thatha kwaloo HTML inye, kodwa sebenzisa .nav-pills
endaweni yoko:
Nyanzelisa .nav
imixholo yakho ukwandisa ububanzi obukhoyo obugcweleyo kwiiklasi ezimbini zesilungisi. Ukugcwalisa ngokulinganayo yonke indawo ekhoyo ngeyakho .nav-item
, sebenzisa .nav-fill
. Qaphela ukuba yonke indawo ethe tye ihleli, kodwa ayizizo zonke izinto ze-nav ezinobubanzi obufanayo.
Xa usebenzisa i- <nav>
navigation navigation, qiniseka ukuba ubandakanya .nav-item
kwiiankile.
Kwizinto ezinobubanzi obulinganayo, sebenzisa .nav-justified
. Zonke isithuba esithe tyaba siya kuhlala ngamakhonkco e-nav, kodwa ngokungafaniyo .nav-fill
nokungasentla, yonke into ye-nav iya kuba nobubanzi obufanayo.
Ngokufana .nav-fill
nomzekelo usebenzisa i- navigation- <nav>
based navigation, qiniseka ukuba uquka .nav-item
kwii-anchors.
Ukuba ufuna ukusabela okwahluka kwe-nav, cinga ukusebenzisa uluhlu lwezinto eziluncedo ze- flexbox . Ngelixa i-verbose ngakumbi, ezi zixhobo zibonelela ngokwenziwa ngokwezifiso okukhulu kuzo zonke iindawo ezisabelayo. Kulo mzekelo ungezantsi, i-nav yethu iya kupakishwa kweyona ndawo isezantsi yoqhawulo, emva koko ilungelelanise ubeko oluthe tye olugcwalisa ububanzi obukhoyo ukusuka kwindawo encinci yokuphumla.
Ukuba usebenzisa i-navs ukubonelela ngebar yokukhangela, qiniseka ukuba wongeza role="navigation"
u-a kwesona sikhongozeli sinomzali sinengqiqo se-, <ul>
okanye usonge into ethile kuhambo <nav>
lonke. Musa ukongeza indima kuyo <ul>
ngokwayo, njengoko oku kuya kuthintela ukuba ibhengezwe njengoluhlu lokwenyani ngobuchule bokuncedisa.
Qaphela ukuba iibar zokukhangela, nokuba zibukeka njenge tabhu kunye .nav-tabs
nodidi, akufunekanga zinikwe role="tablist"
, role="tab"
okanye role="tabpanel"
iimpawu. Ezi zilungele kuphela ujongano oluguquguqukayo lwethebhu, njengoko kuchaziwe kwi- WAI ARIA yeZenzo zokuBhalisa . Jonga ukuziphatha kweJavaScript yojongano oluguquguqukayo lwethebhu kweli candelo lomzekelo.
Yongeza iimenu ezihlayo nge-HTML encinci eyongezelelweyo kunye neplagi ye- JavaScript eyehlayo .
Sebenzisa i-plugin ye-JavaScript yethebhu-yibandakanye ngabanye okanye bootstrap.js
ngefayile ehlanganisiweyo-ukwandisa iithebhu zethu zokuhamba kunye neepilisi ukwenza iipaneli ze-tabhable zesiqulatho sasekhaya, nangeemenyu ezihlayo.
Ukuba wakha iJavaScript yethu kwimvelaphi, kufunautil.js
.
I-Dynamic tabbed interfaces, njengoko ichazwe kwi- WAI ARIA yeZenzo zokuBhalisa , ifuna role="tablist"
, role="tab"
, role="tabpanel"
, kunye neempawu ezongezelelweyo aria-
ukwenzela ukuhambisa isakhiwo sabo, ukusebenza kunye nemeko yangoku kubasebenzisi bobuchwepheshe bokuncedisa (njengabafundi besikrini).
Qaphela ukuba ujongano oluguquguqukayo lwe tab akufuneki luqulathe iimenu ezilahlayo, njengoko oku kubangela zombini ukusetyenziswa kunye nemiba yofikelelo. Ukusuka kwimbono yokusebenziseka, into yokuba isiqalo sethebhu ebonisiweyo ngoku ayibonakali ngokukhawuleza (njengoko ingaphakathi kwimenyu eyehlayo evaliweyo) inokubangela ukubhideka. Ukusuka kumbono wofikelelo, okwangoku akukho ndlela isengqiqweni yokwenza imephu yolu hlobo lolwakhiwo kwipatheni eqhelekileyo ye-WAI ARIA, nto leyo ethetha ukuba ayinakwenziwa lula ukuba iqondeke kubasebenzisi bobuchwephesha bokuncedisa.

Ukunceda ukulingana neemfuno zakho, oku kusebenza <ul>
ngophawu olusekwe-, njengoko kubonisiwe ngasentla, okanye nangaluphi na uphawu olungenamkhethe "rola okwakho". Qaphela ukuba usebenzisa <nav>
, akufuneki udibanise role="tablist"
ngokuthe ngqo kuyo, njengoko oku kuya kubhala ngaphezulu indima yendalo yesiqalelo njengophawu lokukhangela lomhlaba. Endaweni yoko, tshintshela kwenye into (kumzekelo ongezantsi, elula <div>

Iplagi yeethebhu iphinda isebenze kunye neepilisi.

Unokwenza ithebhu okanye ujongo lwepilisi ngaphandle kokubhala nayiphi na iJavaScript ngokuchaza ngokulula data-toggle="tab"
okanye data-toggle="pill"
kwinto. Sebenzisa ezi mpawu zedatha kwi .nav-tabs
okanye .nav-pills
.
Yenza iithebhu ezinokubakho ngeJavaScript (ithebhu nganye kufuneka ivulwe ngokwayo):
Unokwenza ithebhu nganye isebenze ngeendlela ezininzi:
Ukwenza iithebhu ziphelelwe, yongeza .fade
kuyo nganye .tab-pane
. Ipheyini yethebhu yokuqala kufuneka kwakhona .show
yenze umxholo wokuqala ubonakale.
Iindlela ze-Asynchronous kunye notshintsho
Zonke iindlela ze-API zi -asynchronous kwaye ziqala utshintsho . Babuyela kumnxeba ngokukhawuleza nje ukuba utshintsho luqalisiwe kodwa ngaphambi kokuba luphele . Ukongeza, ukufowunelwa kwendlela kwicandelo lenguquko kuya kuhoywa .
Yenza isiqalelo sethebhu kunye nesiqulatho sisebenze. Isithuba kufuneka sibenendawo data-target
okanye indawo href
yesikhongozeli kwiDOM.
Ikhetha isithuba esinikiweyo kwaye ibonise isahlulo sayo esinxulumeneyo. Nayiphi enye isithuba ebesikhe yakhethwa ngaphambili ayikhethwanga kwaye isahlulo sayo esinxulumeneyo siyafihlwa. Ibuyisela kumnxebi phambi kokuba ipayini yethebhu iboniswe ngokwenene (okt phambi kokuba shown.bs.tab
isiganeko senzeke).
Uyonakalisa ithebhu yesiqalelo.
Xa ubonisa ithebhu entsha, iziganeko zivutha ngolu hlobo lulandelayo:
hide.bs.tab
(kwithebhu esebenzayo yangoku)show.bs.tab
(kwi-eza kuboniswa thebhu)hidden.bs.tab
(kwithebhu esebenzayo yangaphambili, efanayo nalehide.bs.tab
yesiganeko)shown.bs.tab
(kwisithuba esandula ukusebenza esivele sibonise ithebhu, efanayoshow.bs.tab
nesesiganeko)
Ukuba akukho thebhu ibisele iyasebenza, ngoko i hide.bs.tab
kunye hidden.bs.tab
neziganeko aziyi kugxothwa.
Uhlobo loMnyhadala | Inkcazo |
---|---|
bonisa.bs.tab | Esi siganeko sivutha kumboniso wethebhu, kodwa ngaphambi kokuba ithebhu entsha iboniswe. Sebenzisa event.target kunye event.relatedTarget nokujolisa isithuba esisebenzayo kunye nesithuba sangaphambili esisebenzayo (ukuba sikhona) ngokulandelelanayo. |
ebonisiweyo.bs.tab | Esi siganeko sitshisa kwi-tab show emva kokuba ithebhu ibonisiwe. Sebenzisa event.target kunye event.relatedTarget nokujolisa isithuba esisebenzayo kunye nesithuba sangaphambili esisebenzayo (ukuba sikhona) ngokulandelelanayo. |
fihla.bs.tab | Esi siganeko sitshisa xa isithuba esitsha siza kuboniswa (kwaye ke isithuba sangaphambili esisebenzayo siza kufihlwa). Sebenzisa event.target kunye event.relatedTarget nokujolisa ithebhu esebenzayo yangoku kunye nethebhu entsha eza kusebenza ngokukhawuleza, ngokulandelelanayo. |
efihliweyo.bs.tab | Esi siganeko sivutha emva kokuba ithebhu entsha ibonisiwe (kwaye ke isithuba sangaphambili esisebenzayo sifihliwe). Sebenzisa event.target kunye event.relatedTarget nokujolisa kwithebhu esebenzayo yangaphambili kunye nethebhu entsha esebenzayo, ngokulandelelanayo. |
