Isticmaalka
Iyada oo loo marayo sifooyinka xogta
Si aad si fudud ugu darto habdhaqanka scrollspy to your topbar navigation, data-spy="scroll"
ku dar walxaha aad rabto in aad basaasto (inta badan tani waxay noqonaysaa <body>
). Ka dib ku dar data-target
sifada aqoonsiga ama fasalka xubinta waalidka ee qayb kasta oo Bootstrap .nav
ah.
Iyadoo loo marayo JavaScript
Ka dib markaad ku position: relative;
darto CSS-gaaga, wac qoraalka qoraalka JavaScript:
Bartilmaameedyada aqoonsiga ee la xallin karo ayaa loo baahan yahay
Xidhiidhiyayaasha Navbar waa inay lahaadaan bartilmaameedyada id la xallin karo. Tusaale ahaan, <a href="#home">home</a>
waa inuu u dhigmaa wax ku jira DOM sida <div id="home"></div>
.
Waxyaabaha aan :visible
bartilmaameedka ahayn waa la iska indhatiray
Walxaha bartilmaameedka ah ee aan :visible
waafaqsanayn jQuery waa la iska indha tiraayaa oo shayada badda ee u dhigma weligood lama iftiimin doono.
Hababka
.scrollspy('refresh')
Markaad isticmaalayso scrollspy iyadoo lala kaashanayo ku darista ama ka saarida walxaha DOM, waxaad u baahan doontaa inaad wacdo habka dib u cusboonaysiinta sida:
.scrollspy('dispose')
Wuxuu baabi'iyaa rog-rogadka curiyaha.
