URLSearchParams.delete() method in ServiceNow

[Pompha]

Hi,

I am trying to use URLSearchParams.delete() method and I am getting a compilation error. 

Error is 

"Could not save record because of a compile error: JavaScript parse error at line (25) column (22) problem = missing name after . operator (<refname>; line 25)"

Code is

var url = top.location.href;
var params = new URLSearchParams(url);
params.delete('foo');

Has anyone seen this issue or know how to fix this issue, please let me know.

Thanks

Hi @Pompha ,

The delete() method of the URLSearchParams interface deletes the given search parameter and all its associated values, from the list of all search parameters.

Syntax: delete(name)

name

The name of the parameter to be deleted.

Here is an example :

let url = new URL('https://example.com?foo=1&bar=2&foo=3');
let params = new URLSearchParams(url.search);

// Delete the foo parameter.
params.delete('foo'); //Query string is now: 'bar=2'


Mark my answer correct & Helpful, if Applicable.

Thanks,

Did you ever figure this out? I'm running into the same issue.

Hey, I'm facing this issue too, any workaround ?

Hi @Pompha @Adeep @Andrew96 ,

Your error is happening because you're passing the full URL (top.location.href) directly to URLSearchParams. The URLSearchParams constructor expects only the query string (the part after ? in a URL), not the full URL.

var url = new URL(top.location.href); // Parse the full URL
var params = new URLSearchParams(url.search); // Extract only the query string
params.delete('foo'); // Remove the parameter

// If you need to update the URL without reloading:
url.search = params.toString();
top.history.replaceState(null, '', url.toString());

HOPE THIS HELP... Please MARK CORRECT OR HELPFUL!!!!
