Javascript judges and obtains trusted sites in the Registry (domain names and IP addresses can be used)

To determine a trusted site, you must first find the location of the trusted site in the Registry, as shown below:

(1) Position of the domain name in the registry as a trusted site:

Hkcu \ Software \ Microsoft \ Windows \ CurrentVersion \ internetsettings

\ Zonemap \ Domains \\

 

(2) ip address as the location of the trusted site in the registry:

Hkcu \ Software \ Microsoft \ Windows \ CurrentVersion \ internetsettings

\ Zonemap \ ranges

 

The specific test code is as follows:

Index. jsp

<! Doctype HTML> 
JS Code:
