vue-scrollspy

Scrollspy, and animated scrolt-to, for VueJS

Installation

$ npm install vue-scrollspy --save

Setup

var Vue = require('vue');
var Scrollspy = require('vue-scrollspy');
Vue.use(Scrollspy)

Usage

HTML:

<ul>
    <li :class="{active:scrollPos == 0}">
        <a @click="$scrollTo(0)">Menu 1</a>
    </li>
    <li :class="{active:scrollPos == 1}">
        <a @click="$scrollTo(1)">Menu 2</a>
    </li>
</ul>

<div v-scrollspy="scrollPos" :steps="30" :time="200">
    <div>
        <h1>Header 1</h1>
        <p>Content</p>
    </div>
    <div>
        <h1>Header 2</h1>
        <p>Content</p>
    </div>
</div>

Javascript:

new Vue({
    data: {
        scrollPos: 0
    },
    ready: function(){
        this.$scrollSet()
    }
})

Using the directive creates the global function $scrollSet(). Call this when the DOM is ready, or when the DOM has changed.

Animated Scroll

For animated scroll, use as follows:

<div v-scrollspy="scrollPos" :steps="30" :time="200">

time in milliseconds, steps is animation resolution (more steps results in a smoother animation). For non-animated scroll, simply omit these parameters.

TODO

• Add bezier animations
• Add innerHTML watcher

(If anybody knows how to watch innerHTML please let me know.)
