英文:
Validate slug with Regexp with slash allowed
问题
我使用正则表达式来验证一个 slug。
const rule = new RegExp('^[A-Za-z0-9]+(-[A-Za-z0-9]+)*$')
尽管它工作得很好，但我想要接受 /
示例：my-parent-page/my-child-page
使用我的原始正则表达式，此 slug 被视为无效，但实际上它应该是正确的。
谢谢

const rule = new RegExp('^[A-Za-z0-9]+(-[A-Za-z0-9]+)*$')
It works well though, I would like to / have them accepted
Example: my-parent-page/my-child-page
With my original Regex, this slug is invalidated while it should be correct
Thank you

Add a slash to the delimiting expression [-/], so the alphanumeric part can be joined by either...
const re = new RegExp('^[A-Za-z0-9]+([-/][A-Za-z0-9]+)*$');
const egs = [
'justSlash/justSlash',
'just-dash',
'dash-and-slash/dash-and-slash',
'&crap'
];
egs.forEach(eg => console.log(re.test(eg) ? "match" : "no match"))
