Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

无限滚动指令。


引入

import { InfiniteScroll } from '@huteming/ui'

Vue.use(InfiniteScroll)
// Vue.directive(InfiniteScroll.name, InfiniteScroll)

例子

为 HTML 元素添加 v-infinite-scroll 指令即可使用无限滚动。滚动该元素,当其底部与被滚动元素底部的距离小于给定的阈值时,绑定到 v-infinite-scroll 指令的方法就会被触发。

<ul v-infinite-scroll="loadMore">
    <li v-for="item in list">{{ item }}</li>
</ul>
loadMore (done) {
    setTimeout(() => {
        let last = this.list[this.list.length - 1]

        for (let i = 1; i <= 10; i++) {
            this.list.push(last + i)
        }

        done()
    }, 2500)
}

API

| 参数 | 说明 | 类型 | 可选值 | 默认值 | |------|-------|---------|-------|--------| | callback | 触发的回调函数。指令参数是function类型时,作为callback | Function(done) | | | | distance | 触发加载方法的滚动距离阈值(像素)) | Number | | 50 | | disabled | 若为真,则无限滚动不会被触发 | Boolean | | false |

修饰符

| 参数 | 说明 | 默认值 | |--------|-----------|--------| | immediate | 若为真,则指令被绑定到元素上后会立即检查是否需要执行加载方法。在初始状态下内容有可能撑不满容器时十分有用 | false |

监听事件

| 事件名称 | 说明 | 示例 | |--------|-----------|--------| | infinite-scroll | 一个 event,被执行时会立即检查是否需要执行加载方法 | this.$emit('infinite-scroll') |
