JavaScript-ActiveXObject
javascript取得机器名，用户名，读写注册表，启动应用程序//javascript有个特殊的对象ActiveXObject，通过它可以访问windows的本地文件系统和应用程序，比如：有的时候我们需要得到用户的机器名，用户名，得到某个文件的信息，或者读写注册表，或者启动计算器、outlook等应用程序。下面是一些常用的方法，每个都经过了测试。<script language="JavaScript">//取得机器名，登录域及登录用户名function getusername(){var WshNetwork = new ActiveXObject("WScript.Network");alert("Domain = " + WshNetwork.UserDomain);alert("Computer Name = " + WshNetwork.ComputerName);alert("User Name = " + WshNetwork.UserName);}//取得系统目录function getprocessnum(){ var pnsys=new ActiveXObject("WScript.shell"); pn=pnsys.Environment("PROCESS"); alert(pn("WINDIR"));}//返回系统中特殊目录的路径function getspecialfolder(){ var mygetfolder=new ActiveXObject("WScript.shell"); if(mygetfolder.SpecialFolders("Fonts")!=null) { alert(mygetfolder.SpecialFolders("Fonts")); }}//取得磁盘信息 传入参数如：getdiskinfo('c')function getdiskinfo(para){ var fs=new ActiveXObject("scripting.filesystemobject"); d=fs.GetDrive(para); s="卷标:" + d.VolumnName; s+="------" + "剩余空间:" + d.FreeSpace/1024/1024 + "M"; s+="------" + "磁盘序列号:" + d.serialnumber; alert(s)}//取得系统目录function getprocessnum(){ var pnsys=new ActiveXObject("WScript.shell"); pn=pnsys.Environment("PROCESS"); alert(pn("WINDIR"));}//启动计算器function runcalc(){ var calc=new ActiveXObject("WScript.shell"); calc.Run("calc");}//读取注册表中的值function readreg(){ var myreadreg=new ActiveXObject("WScript.shell"); try{ alert(myreadreg.RegRead ("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\NeroCheck")); } catch(e) { alert("读取的值不存在！"); }}//写注册表function writereg(){ var mywritereg=new ActiveXObject("WScript.shell"); try{ mywritereg.RegWrite("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\MyTest","c:\\mytest.exe"); alert("写入成功！"); } catch(e) { alert("写入路径不正确！"); }}//删除注册表function delreg(){ var mydelreg=new ActiveXObject("WScript.shell"); if(confirm("是否真的删除？")) { try{ mydelreg.RegDelete("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\MyTest"); alert("删除成功！");}catch(e){ alert("删除路径不正确");} }}//取得文件信息 调用方式如：getfileinfo('c:\\test.pdf')function getfileinfo(para){ var myfile=new ActiveXObject("scripting.filesystemobject"); var fi=myfile.GetFile(para); alert("文件类型:"+fi.type+"文件大小:"+fi.size/1024/1024+"M"+"最后一次访问时间:"+fi.DateLastAccessed);}//取得客户端的信息function clientInfo(){ strClientInfo="availHeight= "+window.screen.availHeight+"\n"+"availWidth= "+window.screen.availWidth+"\n"+"bufferDepth= "+window.screen.bufferDepth+"\n"+"colorDepth= "+window.screen.colorDepth+"\n"+"colorEnable= "+window.navigator.cookieEnabled+"\n"+"cpuClass= "+window.navigator.cpuClass+"\n"+"height= "+window.screen.height+"\n"+"javaEnable= "+window.navigator.javaEnabled()+"\n"+"platform= "+window.navigator.platform+"\n"+"systemLanguage= "+window.navigator.systemLanguage+"\n"+"userLanguage= "+window.navigator.userLanguage+"\n"+"width= "+window.screen.width; alert(strClientInfo); }</script>//另存为excel文件并写入值function saveas(){var ExcelApp = new ActiveXObject("Excel.Application");var ExcelSheet = new ActiveXObject("Excel.Sheet") ExcelSheet.Application.Visible = true; ExcelSheet.ActiveSheet.Cells(1,1).Value = "This is column A, row 1"; ExcelSheet.SaveAs("C:\\TEST.XLS"); ExcelSheet.Application.Quit(); alert('ok')；}
