Javascript Regex - 如何在图像路径之前提取最后一个单词 [英] Javascript Regex - How to extract last word before path to image

问题描述

我想使用正则表达式从文件路径中提取最后一个单词.例如，我有:/xyz/blahblah/zzz/abc-blah/def-xyz-颜色.jpg

I want to use regex to extract the last word from a file path. For example, I have: /xyz/blahblah/zzz/abc-blah/def-xyz-color.jpg

我想从路径中提取颜色".路径颜色有不同的语法.唯一一致的是结尾总是 -color.jpg，其中 color 是任何 [a-z] 字.

I want to extract the "color" out of the path. The path color have different syntax. The only thing that is consistent is the ending where it is always -color.jpg where color would be any [a-z] word.

有没有一种优雅的方法来做到这一点?

Is there an elegant way to do this?

我真的很感激这里的任何帮助.谢谢

var matched = /-(\w+).jpg/i.exec('/xyz/blahblah/zzz/abc-blah/def-xyz-color.jpg')[1];
