is the current page url: window.location.pathname.substr(1).split('/')

Not the current page url: url.replace(/http(s){0,1}://[^/]+//, '').split('/')

window.location.pathname.split('/')

This requires the use of assertions

const str = 'http://www.xxx.com/one/two/three/four';

const result = str.match(/(?/[\/])\w+/g).map((item) => { return item.substr(1);});

// 输出
// ["www", "one", "two", "three", "four"]
