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 🙏

这是一个数字转换为汉字的案例 如输入123---转换为一百二十三

基本使用:先创建一个函数fn

// 判断里面是否有字母或别的 if(!/^\d*$/.test(n)){ return "数字输入有误" } var reg = new RegExp("([0]*)([1-9]+[0-9]+)", "g"); n = n.replace(reg, "$2") // console.log(n) var unit = '千百十亿千百十万千百十个';

if (n.length > unit.length) { return '数据过长'; } var newStr = ''; var nlength = n.length; unit = unit.substr(unit.length - nlength); for (var i = 0; i < nlength; i++) { newStr += '零一二三四五六七八九'.charAt(n[i]) + unit.charAt(i); } newStr = newStr.substr(0, newStr.length - 1); // $1:捕捉第一个匹配的结果 newStr = newStr.replace(/零(千|百|十)/g, '零').replace(/(零)+/g, '零').replace(/零(亿|万)/g, '$1'); for (var i = newStr.length - 1; i > 0; i--) { if (newStr[i] == "零") { newStr = newStr.replace(newStr[i], "") } else { break; } } return newStr;
