Kugirango wongere byoroshye imyitwarire ya scrollspy kumurongo wawe wo hejuru, ongera kubintu ushaka kuneka data-spy="scroll"(mubisanzwe ibi byaba aribyo <body>). Noneho ongeraho data-targetikiranga hamwe nindangamuntu cyangwa urwego rwibintu byababyeyi .navbigize Bootstrap.

body {
  position: relative;
}

<body data-spy="scroll" data-target="#navbar-example">
  ...
  <div id="navbar-example">
    <ul class="nav nav-tabs" role="tablist">

Binyuze kuri JavaScript

Nyuma yo kongera position: relative;muri CSS yawe, hamagara umuzingo ukoresheje JavaScript:

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

Intego z'indangamuntu zikemurwa zisabwa

Imiyoboro ya Navbar igomba kuba ifite intego id idakemuka. Kurugero, <a href="#home">home</a>hagomba guhura nibintu muri DOM nka <div id="home"></div>.

Ibintu bitari `:visible`intego birengagijwe

Intego yibintu bidahuye :visiblena jQuery izirengagizwa kandi ibintu bihuye nabyo ntibizigera bigaragara.

Uburyo

`.scrollspy('refresh')`

Mugihe ukoresheje umuzingo ufatanije no kongera cyangwa gukuraho ibintu muri DOM, uzakenera guhamagara uburyo bushya nka gutya:

$('[data-spy="scroll"]').each(function () {
  var $spy = $(this).scrollspy('refresh')
})

`.scrollspy('dispose')`

Gusenya ikintu cyizingo.
