Getting the url params of outside iframe

[Aprime]

Ahoy,

I'd like to get the params of the newgrounds website from a game that's in an iframe on Newgrounds.

I'm creating an invite system that allows the player to share a url with their friends to play them.

We can do stuff like

let searchParams = new URLSearchParams(window.location.search)
param = searchParams.get('invite')

However, to get the url of the parent we can do

var url = document.referrer

or

var url = (parent !== window) ? document.referrer : document.location;

is there a way I can do this but obtain the actual params?

I'm thinking the answers no, because newgrounds hosts the games on a subdomain and there's the crossorigin request stuff that'll get in the way.

But heyho, just trying my luck, is it possible?

Cheers

UPDATE: maybe there's a way via the API?

I suspect you're right and it's not possible, I get cross origin request blocks if I try to do anything along those lines.

I'm guessing the game's being run from a server since multiple players would playing directly with each other -- maybe take another approach (if you can do this from the server) of having player A invite player B (will need to know their NG user name), player B gets a link to the game's regular page without a query string, the server checks the user name (via the API) of anyone who joins, and if player A's invite to player B is still active and player B logs in it gives them an option of joining player A's game? The drawback is that players would have to have NG accounts (at least the invite-ee).

Wow! Great idea! Thank you so much!! I definitely wouldn't have thought of that!
