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 🙏

图片懒加载

页面多块区域垂直水平滚动后的图片懒加载

预览地址

1: npm引入

npm i -S i-lazy-load

2:获取dist目录下面文件

使用说明:

注意: 使用插件之前需要用css把页面的布局好,图片容器一定需要设置宽度和高度


var windowImgLoad = new ImgLazyLoad({
  target: window,
  el: '.body-wrap',
  distance: 50,
  interval: 250,
  beforeLoad: function(el) {
    console.log(el)
  },
  finishLoad: function(el) {
    console.log(el)
  },
  errorLoad: function(el, event) {
    console.log(el, event)
  }
})

参数说明:
target      null|window      如果是整个页面滚动需要这是target为window
el          string           需要滚动的区域元素
distance    number           距离可视区多远的距离开始加载图片
interval    number           滚动条停止多少毫秒后执行懒加载
beforeLoad  function         图片开始加载执行函数
finishLoad  function         图片加载成功执行函数
errorLoad   function         图片加载错误执行函数
外部调用方法:
windowImgLoad.refresh();
windowImgLoad.distroryed();

refresh()      重新初始化加载图片(用于无限滚动或者分页)
distroryed()   销毁滚动事件
