在 Javascript 中提取字符串的更好方法

Question

I've a string which is

xyz.com/test/classified/electronics/home-audio-turntables/amplifiers/new/ .

I want to extract following value from above string ie, /classified/electronics/home-audio-turntables/amplifiers/

I'm able to achieve with below logic but is there a better way than this? Appreciate suggestions

window.location.href.split('test')[1].split('/new')[0]

Answer 1

I think what you are looking for is window.location.pathname

In case of testing:

window.location.pathname.replace(/^(\/test)?/, '')

Answer 2

A regular expression can match what comes between.

 const str = 'xyz.com/test/classified/electronics/home-audio-turntables/amplifiers/new/'; const result = str.match(/test(\\/.*?\\/)new/)[1]; console.log(result);

Or with lookbehind

 const str = 'xyz.com/test/classified/electronics/home-audio-turntables/amplifiers/new/'; const result = str.match(/(?<=test)\\/.*?\\/(?=new)/)[0]; console.log(result);
