How to cut part of string in vanilla js to send like as parameter on API

I have a little problem with this url.

I want to get only the numbers on the first drop down and send it like as paramater on API.

I create a object with properties:

const dataAPI = { nameStation: '', nameStationNumber: '', dateStation: '', dataHours: '' }

and I want dataAPI.nameStationNumber to save only a number of clicked value.

With this code I get only this string for example:

Chepelarska - 18694 - HPoint-Water level 

dataAPI.nameStation = e.target.innerHTML.replace(/.*\+\s?/, '');

How can I cut only 18694 from река Чепеларска - гр. Асеновград + Chepinska - 10084 - HPoint-Water level

Can I get example how to do that ?

>Solution :

Use regex /[^\d]+/ (replace [^] anything that does not match \d (number))

let string = 'река Чепеларска - гр. Асеновград + Chepinska - 10084 - HPoint-Water level';
let result = string.replace(/[^\d]+/g, '');
console.log(result);
