Hi ku tisungulela pfuxeta ku famba-famba ka Bootstrap kumbe ku xaxameta swiphemu swa ntlawa hi ku ya hi xiyimo xa ku rhendzeleka ku kombisa leswaku hi xihi xihlanganisi lexi tirhaka sweswi eka xivono.

Ndlela leyi swi tirhaka ha yona

Scrollspy yi na swilaveko swi nga ri swingani leswaku yi tirha kahle:

  • Loko u aka JavaScript ya hina ku suka eka xihlovo, swi lavautil.js .
  • Yi fanele ku tirhisiwa eka xiphemu xa nav xa Bootstrap kumbe ntlawa wa nxaxamelo .
  • Scrollspy yi lava position: relative;eka elemente leyi u yi hlotaka, hi ntolovelo <body>.
  • Loko u hlota swiaki swin’wana handle ka <body>, tiyiseka leswaku u ni heightsete ni ku overflow-y: scroll;tirhisiwa.
  • Tianchor ( <a>) ta laveka naswona ti fanele ku kombetela eka elemente leyi nga na sweswo id.

Loko yi tirhisiwile hi ndlela leyi humelelaka, ntlawa wa wena wa nav kumbe wa nxaxamelo wu ta pfuxeta hi ku landza sweswo, wu rhurhela .activetlilasi ku suka eka nchumu wun’wana ku ya eka wun’wana hi ku ya hi swikongomelo swa wona leswi fambisanaka na swona.

Xikombiso eka navbar

Hi ku tirhisa swihlawulekisi swa data

Ku engetela hi ku olova mahanyelo ya scrollspy eka ku famba-famba ka wena ka topbar, engetela data-spy="scroll"eka elemente leyi u lavaka ku hlota eka yona (hi ntolovelo leswi swi ta va swi ri <body>). Kutani engetela data-targetxihlawulekisi hi ID kumbe tlilasi ya elemente ya mutswari ya xiphemu xihi na xihi .navxa Bootstrap.

body {
  position: relative;
}
<body data-spy="scroll" data-target="#navbar-example">
  ...
  <div id="navbar-example">
    <ul class="nav nav-tabs" role="tablist">
      ...
    </ul>
  </div>
  ...
</body>

Hi ku tirhisa JavaScript

Endzhaku ko engetela position: relative;eka CSS ya wena, vitana scrollspy hi ku tirhisa JavaScript:

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

Swikongomiso swa ID leswi nga lulamisiwaka swa laveka

Swihlanganisi swa Navbar swi fanele ku va na swikongomelo swa id leswi nga lulamisiwaka. Xikombiso, a yi <a href="#home">home</a>fanele ku fambisana na nchumu wo karhi eka DOM ku fana na <div id="home"></div>.

Swiaki leswi nga riki :visibleswa xikongomelo swi honisiwile

Swiaki leswi kongomisiweke leswi nga riki :visiblehi ku ya hi jQuery swi ta honisiwa naswona swilo swa swona swa nav leswi fambelanaka a swi nge pfuki swi kombisiwile.

Maendlelo

.scrollspy('refresh')

Loko u tirhisa scrollspy hi ku fambisana na ku engetela kumbe ku susa swiaki eka DOM, u ta lava ku vitana ndlela yo pfuxeta ku fana na sweswo:

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

.scrollspy('dispose')

Ku herisa scrollspy ya elemente.

Swihlawulekisi

Swihlawulekisi swi nga hundzisiwa hi ku tirhisa swihlawulekisi swa data kumbe JavaScript. Eka swihlawulekisi swa datha, engetela vito ra xihlawuhlawu eka data-, tanihi le ka data-offset="".

Vito Muxaka Ku tlula Nhlamuselo
