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 🙏

版本

  • v1.0.4

基于

  • vue2
  • interaction observe

安装

npm install x-lazy-load-vue

使用

在main.js中引入

import XLazyLoad from 'x-lazy-load-vue';

Vue.use(XLazyLoad)

组件中使用

<x-lazy-load
  :dom-class="lazy-dom"
  :dom-attrs="['ids']"
  :times="1"
  :had-mounted-number="mountedNumber"
  @handleLazyData="handleLazyData"
>
    //slot的内容,layzid是返回结果里的key,必须填写!!!!
    <div lazyid='id'></div>
</x-lazy-load>

返回值

{
    lazyid: {
       attr1: value,
       attr2: value,
       ...dom-attrs里的attr
    }
}

说明

参数说明

dom-class[字符串] : 需要监听dom的class属性值
dom-attrs[数组] : 监听返回的dom上的attributes属性名
times[数值] : 监听几次,1代表返回一次以后,就不返回了
had-mounted-number[数值] : 触发内部监听的prop,当该prop变化,会再次监听dom-class
handleLazyData[方法] :emit的接收方法,会接收返回的监听的dom-attrs

场景

  • slot里为需要监听的dom组;
  • 动态更新需要监听的dom时,更新prop值mountedNumber + 1;
  • handleLazyData方法接收已出现在可视区域的dom-attrs;
  • 接收到返回值后,完成后续的业务操作。
