本文实例讲述了javascript判断并获取注册表中可信任站点的方法。分享给大家供大家参考。具体分析如下:
判断可信任站点,首先要在注册表中找到可信任站点在注册表中的位置,如下:
(1)域名作为可信任站点在注册表中的位置:
HKCU//Software//Microsoft//Windows//CurrentVersion//InternetSettings//ZoneMap//Domains//
(2)IP作为可信任站点在注册表中的位置:
HKCU//Software//Microsoft//Windows//CurrentVersion//InternetSettings//ZoneMap//Ranges
具体测试代码如下:
index.jsp:
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>获取并判断可信任站点(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="是否是可信站点" id="testRegister" /></div></body></html>
js代码:
/* * 判断可信任站点(可信任站点可以为IP地址也可以为域名) */ window.onload = function(){ var btnObj = document.getElementById("testRegister"); btnObj.onclick = function(){ if(navigator.userAgent.indexOf("MSIE") == -1){ alert("只支持IE浏览器!"); return; } var hostname = window.location.hostname; var WshShell = new ActiveXObject("WScript.Shell"); //IP的正则表达式 var reg = /^(/d{1,2}|1/d/d|2[0-4]/d|25[0-5])(/.(/d{1,2}|1/d/d|2[0-4]/d|25[0-5])){3}$/; //根据域名判断是否存在可信站点 if(hostname != "localhost" && !reg.test(hostname)){ var domainSFlag = false,domainEFlag = false,domainSEFlag = false,domainSSEFlag = true; var hostnamePrefix = "",hostnameSuffix = ""; var indexOf = hostname.indexOf("."); if(indexOf != -1){ hostnamePrefix = hostname.substring(0, indexOf); hostnameSuffix = hostname.substring(indexOf+1, hostname.length); try{ WshShell.RegRead("HKCU//Software//Microsoft//Windows//CurrentVersion//Internet Settings//ZoneMap//Domains//" + hostname + "//http"); }catch(e){ domainEFlag = true; } if(domainEFlag){ try{ WshShell.RegRead("HKCU//Software//Microsoft//Windows//CurrentVersion//Internet Settings//ZoneMap//Domains//" + hostnameSuffix + "//" + hostnamePrefix + "//http"); }catch(e){ domainSFlag = true; } } //判断其合法性 if(domainEFlag && domainSFlag){ try{ WshShell.RegRead("HKCU//Software//Microsoft//Windows//CurrentVersion//Internet Settings//ZoneMap//Domains//" + hostnameSuffix + "//" + hostnamePrefix + "//*"); var tipInfo = "<div>您加入的可信站点不是合法的可信站点,请以<span style='color:red;'>http://</span>开头!</div>"; alert(tipInfo); return; }catch(e){} } }else{ try{ WshShell.RegRead("HKCU//Software//Microsoft//Windows//CurrentVersion//Internet Settings//ZoneMap//Domains//" + hostname + "//http"); }catch(e){ domainSEFlag = true; } //判断其合法性 if(domainSEFlag){ try{ WshShell.RegRead("HKCU//Software//Microsoft//Windows//CurrentVersion//Internet Settings//ZoneMap//Domains//" + hostname + "//*"); var tipInfo = "<div>您加入的可信站点不是合法的可信站点,请以<span style='color:red;'>http://</span>开头!</div>"; alert(tipInfo); return; }catch(e){} } } if((domainSFlag && domainEFlag) || domainSEFlag){ var tipInfo = "域名为" + hostname + "的可信任站点不存在!"; alert(tipInfo); alert(tipInfo); return; } }else{ //获取可信任站点IP,数字2000没法解释,主要涉及到注册表的问题 var str = []; for(var i = 1;i < 2000;i++){ try{ str[i] = WshShell.RegRead("HKCU//Software//Microsoft//Windows//CurrentVersion//Internet Settings//ZoneMap//Ranges//Range" + i + "//:Range"); }catch(e){ } } var count = true; for(var i = 1;i < str.length;i++){ if(str[i] == undefined){ continue; }else{ if(str[i] == hostname){ count = false; break; } } } if(count){ var tipInfo = "IP为" + hostname+"可信任站点不存在!"; alert(tipInfo); return } } alert("存在可信任站点!"); } }
