<!-- nav bar -->
<div class="navbar">
<VScrollActive offset="40" :hash="true" @update="handleNavbarChange">
...
<span data-scroll-active="menuOne">menu one</span>
</VScrollActive>
</div>
<!-- main page -->
<div class="container">
...
<div id="menuOne"></div>
</div>// window
// const VScrollActive = window['VScrollActive'];
// commonjs like
// const VScrollActive = require('v-scroll-active');
// es module, typescript
import VScrollActive from './VScrollActive.vue';
// Vue.use(VScrollActive); // global
export default {
components: {
VScrollActive // local
},
methods: {
handleNavbarChange(id) {
console.log('current active id is ' + id);
}
}
};Add data-scroll-active to the navigation menu and assign an element id. When the page scrolls to the element, it will add active to the class of the navigation menu.
At the same time, clicking the navigation menu will also make the page scroll to the corresponding element position.
在导航菜单上添加 data-scroll-active ，赋值一个元素 id，在页面滚动到该元素的时候，就会给导航菜单的 class 添加 active。
同时点击该导航菜单也会让页面滚动到对应元素位置。
