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+" "+ "availWidth= "+window.screen.availWidth+" "+ "bufferDepth= "+window.screen.bufferDepth+" "+ "colorDepth= "+window.screen.colorDepth+" "+ "colorEnable= "+window.navigator.cookieEnabled+" "+ "cpuClass= "+window.navigator.cpuClass+" "+ "height= "+window.screen.height+" "+ "javaEnable= "+window.navigator.javaEnabled()+" "+ "platform= "+window.navigator.platform+" "+ "systemLanguage= "+window.navigator.systemLanguage+" "+ "userLanguage= "+window.navigator.userLanguage+" "+ "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'); }
