Pass URL parameters - service portal

[arobertson]

Hi,

I've been using the following script (below) for years to pass URL parameters and just found out that it does not work in Service Portal. I've seen a few possible workarounds but none of them worked.

Anyone have a good solution to getting this to work in Service Portal? i would normally use the below in an onLoad script.

Closest thing i found to a workable fix is: https://jace.pro/post/2018-07-15-sp-set-variables-via-url/ but not 100% clear how to implement it.

var appointment = getParameterValue('sysparm_appointment');

function getParameterValue(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(window.location);
if (results == null) {
return "";
} else {
return unescape(results[1]);
}
}

Hi,

that's because window object is not recommended by ServiceNow; instead use this and check

var url = top.location.href;
var appointment = new URLSearchParams(url).get("sysparm_appointment");

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks

Many thanks 🙂

I was able to get away with replacing window.location with top.location.href

Much appreciated.
