Scrollspy, and animated scroll-to, for Vue2, inspired by vue-scrollspy. See https://ibufu.github.io/vue2-scrollspy/ or Jsfiddle.

$ npm install vue2-scrollspy --save

<script src="//unpkg.com/vue2-scrollspy/dist/index.js"></script>

import Vue from 'vue';
import Scrollspy from 'vue2-scrollspy';
// use default options
Vue.use(Scrollspy);

// or custom options
Vue.use(Scrollspy, options);

<ul v-scroll-spy-active v-scroll-spy-link>
    <li>
        <a>Menu 1</a>
    </li>
    <li>
        <a>Menu 2</a>
    </li>
</ul>

<div v-scroll-spy>
    <div>
        <h1>Header 1</h1>
        <p>Content</p>
    </div>
    <div>
        <h1>Header 2</h1>
        <p>Content</p>
    </div>
</div>

Old Browsers like IE11:

import Scrollspy from "vue2-scrollspy/dist/index";
Vue.use(Scrollspy);

Declares container of sections for elements to scrollspy.

1. v-scroll-spy="{data: 'section'}": add a section data property in scope Vue instance that is binded to the section index.

2. v-scroll-spy="{allowNoActive: true}": allow no active sections when scroll position is outside of the scrollspy container. Default behavior is too keep active at least one section in any case.

3. v-scroll-spy="{offset: 50}": add an offset for scroll and active events.

4. v-scroll-spy="{time: 200, steps: 30}": set the animation options.

5. $scrollTo(index: int) is provided on scope Vue instance to invoke a scroll to the given section index.

6. v-section-selector: set section which should scrollto

Set the active css class on element that match the index of current scrollspy.

1. v-scroll-spy-active="{selector: 'li.menu-item', class: 'custom-active'}": customize elements selection and class name to apply. By default, it will use direct children and apply active class.

Add click handler on children elements that will scroll to the related section.

1. v-scroll-spy-link="{selector: 'a.menu-link'}": customize elements selection. By default, it will use a to select all links.

Example:

import scrollSpy, { Easing } from 'vue2-scrollspy';

Vue.use(scrollSpy, {
  easing: Easing.Cubic.In
});

You should have the same number of children elements for v-scroll-spy, v-scroll-spy-active v-scroll-spy-link for directives to work properly.

If you need to share multiple scroll-spy in the same page, you can add data-scroll-spy-id="" on each element where a directive is declared.

If you want to set something else (not body) to scroll container, you could:

<div class="container" v-scroll-spy>
    <div>
        <h1>Header 1</h1>
        <p>Content</p>
    </div>
    <div>
        <h1>Header 2</h1>
        <p>Content</p>
    </div>
</div>

.container {
  position: relative;
}

npm i && npm run watch 

cd docs-src && npm i && npm run dev
