How to get utm tags from url?

Question

JavaScript

You need to get all utm tags from url and pack them into variables.
The result should be:
medium = "x"
source = "y"
campaign = "z"
content = "k"
Url: https://pro-jector.site/?utm_medium=cpc&utm_source...
How can this be done?

Answer 1

Object.fromEntries((url.match(/(?<=utm_).+?=[^&]*/g) || []).map(n => n.split('=')))

or

[...url.matchAll(/utm_([^=]+)=([^&]*)/g)].reduce((acc, [ , k, v ]) => (acc[k] = v, acc), {})

or

Array
  .from(new URL(url).searchParams)
  .filter(n => n[0].startsWith('utm_'))
  .reduce((acc, n) => ({ ...acc, [n[0].slice(4)]: n[1] }), {})
