Tšhomišo

Ka dika ya data

Go oketša gabonolo boitshwaro bja scrollspy go go sepelasepela ga gago ga topbar, oketša data-spy="scroll"go elemente yeo o nyakago go e hlola (ka tlwaelo kudu se e be e tla ba <body>). Ke moka o tlaleletše data-targetseka ka ID goba sehlopha sa elemente ya motswadi ya karolo efe goba efe ya Bootstrap .nav.

body {

Ka JavaScript

Ka morago ga go tlaleletša position: relative;ka go CSS ya gago, bitša scrollspy ka JavaScript:

$('body').scrollspy({ target: '#navbar-example' })

Diphetho tša ID tšeo di ka rarollwago di a nyakega

Dikgokagano tša Navbar di swanetše go ba le diphetho tša id tšeo di ka rarollwago. Go fa mohlala, a e <a href="#home">home</a>swanetše go sepelelana le selo se sengwe ka go DOM go swana le <div id="home"></div>.

Dielemente tšeo e sego tša `:visible`nepišo di hlokomologwa

Dielemente tša nepišo tšeo di sego :visiblego ya ka jQuery di tla hlokomologwa gomme dilo tša tšona tša nav tše di swanetšego di ka se tsoge di hlaotšwe.

Mekgwa ya go šoma

`.scrollspy('refresh')`

Ge o diriša scrollspy ka kopanelo le go tlaleletša goba go tloša dielemente go tšwa go DOM, o tla swanelwa ke go bitša mokgwa wa go hlabolla go swana le bjalo:

`.scrollspy('dispose')`

E senya scrollspy ya elemente.
