Regex filter uuid from string [closed]-CodePudding

Closed. This question needs to be more

const s = "Floor_f4e88618-22a5-11ec-9621-0242ac130002_Location";
const result = s.match(/Floor_(.*?)_Location/)[1];
console.log(result);

2) Using Regex /(?<=_).*?(?=_)/

const s = "Floor_f4e88618-22a5-11ec-9621-0242ac130002_Location";
const result = s.match(/(?<=_).*?(?=_)/)[0];
console.log(result);

3) You can achieve the same result using slice

const s = "Floor_f4e88618-22a5-11ec-9621-0242ac130002_Location";
const result = s.slice(s.indexOf("_")   1, s.lastIndexOf("_"));
console.log(result);

CodePudding user response：

You can also solve this without a regex, if you have this strict format:

const test = "Floor_f4e88618-22a5-11ec-9621-0242ac130002_Location"

const uuid = test.split('_')[1]

console.log(uuid)

This benefits from the fact that uuid doesn't contain a _
