im aware that because of security reasons browsers wont let you read other tabs
but there is something i wanna know if the parent can open the popup page and close the popup page that means the popup page is still can be accessed through parent page
but is there any slightest chance where the parent page can read url of the popup page
using javascript or any library ? if so how ? considering there is no content security headers present for that popup page
iframe is getting blocked because x-frame headers
all i wanted is to just grab the url
You could access it with myWindow.location.href but only if both windows are on the same subdomain.
Otherwise it is impossible due to same origin policies. Your best option would be to store the url in a variable
