JavaScript to determine and get a trusted site in the registry method _javascript tips

The examples in this article describe the methods that JavaScript can take to determine and obtain trusted sites in the registry. Share to everyone for your reference. The specific analysis is as follows:

To determine the trusted site, first find the location of the trusted site in the registry in the registry, as follows:

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

Hkcu\\software\\microsoft\\windows\\currentversion\\internetsettings\\zonemap\\domains\\

(2) IP 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:

* * To determine the trusted site (can be trusted site for IP address can also be domain name)/window.onload = function () {var btnobj = document.getElementById ("Testregiste 
  R "); Btnobj.onclick = function () {if (Navigator.userAgent.indexOf ("msie") = = 1) {alert ("Support IE browser only!") 
      "); 
    Return 
    var hostname = Window.location.hostname;

      var hostnameprefix = "", Hostnamesuffix = "";
