Storing parsed URL in Cookie (not storing the entire value)

TL;DR: I am forced to use a javascript solution to store a URL parameter as a cookie, but when the function runs, it only stores the first 5 characters of the value I need.

I am working on implementing affiliate sales tracking across domains. As stated above, I need to store a value from a URL in a cookie so that I can pull it into a separate (functioning) script later. On my primary domain, I was able to do this with a simple .php script, but the third-party platform we use for our sales doesn't allow me to run .php scripts, so I found a javascript function that seemed to be working prior to today. That said, prior to today I was using test parameters that were only numerical (1234567890, etc.).

Here is an example of the kind of URL and parameter being used:

This is the function I've been using successfully up until now:

 function getParameterByName(name) { name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]'); var regex = new RegExp('[\\?&]' + name + '=([^&#]*)'), results = regex.exec(location.search); return results === null ? '' : decodeURIComponent(results[1].replace(/\+/g, ' ')); } var results = getParameterByName('irclickid'); if (results != null || results != '') { Cookies.set('irclickid', results, { expires: 30 }); }

For some reason, the function now only stores the first 5 characters of the value, or "QW6Qn" in this case. Any help or direction on how to make this work correctly is appreciated.

Resolution:

I found a function that was more apt for what I needed here on stackoverflow: How to get parameter name?, and replaced the first part of my javascript with the following, and it is now working as expected!

function getParameterByName(name, url) { if (!url) url = window.location.href; name = name.replace(/[\[\]]/g, "\\$&"); var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"), results = regex.exec(url); if (!results) return null; if (!results[2]) return ''; return decodeURIComponent(results[2].replace(/\+/g, " "));
}

The last section remained the same:

 var results = getParameterByName('irclickid'); if (results != null || results != '') { Cookies.set('irclickid', results, { expires: 30 }); }

Thank you to those that offered help and insight.

const url = new URL(')
document.cookie = `irclickid=${url.searchParams.get('irclickid')}; expires=...`

You can see on if all required browsers support URL.
