Is this code crossbrowser?

Question

JavaScript

there is a main window
and there is an iframe inside it,
the script inside the iframe checks if the urls match

if(decodeURIComponent(window.location) === decodeURIComponent(top.айфрейм.src) + '/')

on my machine (mac firefox mamp) I had to add a slash
everywhere will such a cat work?

Answer 1

And what about the browser?
See source code and server operation.
If you have src without a slash in your iframe, and adding a slash is installed on the server, then this is the only way it will work.
Because window.loation is overwritten when you visit the page.
