javascript判斷並獲取注冊表中可信任站點的方法

   本文實例講述了javascript判斷並獲取注冊表中可信任站點的方法。分享給大家供大家參考。具體分析如下:

  判斷可信任站點,首先要在注冊表中找到可信任站點在注冊表中的位置,如下:

  (1)域名作為可信任站點在注冊表中的位置:

  HKCUSoftwareMicrosoftWindowsCurrentVersionInternetSettingsZoneMapDomains

  (2)IP作為可信任站點在注冊表中的位置:

  HKCUSoftwareMicrosoftWindowsCurrentVersionInternetSettingsZoneMapRanges

  具體測試代碼如下:

  index.jsp:

  ?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>獲取並判斷可信任站點(域名和IP)</title> <style type="text/css"> .mainContent{ margin: 0 auto; margin-top: 100px; margin-left: 100px; } </style> <script type="text/javascript" src="js/testRegister.js"></script> </head> <body> <div class="mainContent"> <input type="button" value="是否是可信站點" id="testRegister" /> </div> </body> </html>

  js代碼:

  ?

  希望本文所述對大家的javascript程序設計有所幫助。
