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 🙏

scroller

tags: scroller

这是个移动端和pc端通用的检测滑动的库。

功能

  1. 触顶/触底的触发函数。 即:在滑块在一定范围内到达顶部或者打到底部,亦或者二者均可的触发指定函数。
  2. 离开触顶/触底触发函数。 有些情况我们不仅需要滑块触顶或者触底,在滑块离开二者的一定范围时也需要触发一些函数。
  3. 设置触顶/触底的阈值。
  4. 集成节流阀,可设置频率,提高性能。

用法

scroller({
    fElement:dom<obj>,
    threshold?:<number>,
    arrived:<function>,
    unarrived:<function>,
    up?:<number>,
    down?:<number>,
    modal?:'debounce'/'throttle'<string>,
    frequency?:250<number>
})

往 scroller中添加一个对象即可

  • fElement: 父元素对象
  • threshold: 默认的到达底部的阈值,比如默认值20,也就是说在到达底部的20px范围呢可触发arrived函数。
  • arrived:达到顶部或者底部的触发函数
  • unarrived:离开顶部或者底部的触发函数
  • up:阈值,如果设置则触发下拉到达顶部的函数(默认为null)
  • down:阈值,如果设置则为到达底部的阈值。(默认值等于threshold
  • modal:节流阀模式。debounce:防抖;throttle:减少频率;
  • frequency:节流阀的频率,默认为250。
