正则表达式，从路径中提取子字符串

Question

Doing this in javascript.在 javascript 中执行此操作。

I have path's like this: /p/BC3eKD-rX-w/我有这样的路径：/p/BC3eKD-rX-w/

I have a pattern like this: /\\/p\\/([\\w-]+)\\//g我有一个这样的模式： /\\/p\\/([\\w-]+)\\//g

I am trying to extract "BC3eKD-rX-w" but it keeps matching the entire string.我试图提取“BC3eKD-rX-w”，但它一直匹配整个字符串。

I suck at regular expressions, have spent 2 hours reading and watching videos and am very frustrated.我不擅长正则表达式，花了 2 个小时阅读和观看视频，感到非常沮丧。

Help?帮助？

var exp = /\/p\/([\w-]+)\//g;
console.log(exp.exec("/p/BC3eKD-rX-w/")[1]);

Works fine with me.对我来说很好用。
