To easily add scrollspy behavior to your topbar navigation, just add data-spy="scroll" to the element you want to spy on (most typically this would be the body) and data-target=".navbar" to select which nav to use. You'll want to use scrollspy with a .nav component.
<body data-spy="scroll" data-target=".navbar">...</body>
Call the scrollspy via JavaScript:
query('#navbar').scrollspy()<a href="#home">home</a> must correspond to something in the dom like <div id="home"></div>.Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset="".
| Name | type | default | description |
|---|---|---|---|
| offset | number | 10 | Pixels to offset from top when calculating position of scroll. |
| Methods | Description |
|---|---|
| refresh | When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so: |
query('[data-spy="scroll"]').forEach(function () {
var queryspy = query(this).scrollspy('refresh')
});
| |
| Event | Description |
|---|---|
| activate | This event fires whenever a new item becomes activated by the scrollspy. |
The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the area below the navbar and watch the active class change. The dropdown sub items will be highlighted as well.
