1.javascript取得机器名，用户名，读写注册表，启动应用程序 2.//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， 3.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。 4. 5.下面是一些常用的方法，每个都经过了测试。 6.<script language="JavaScript"> 7.//取得机器名，登录域及登录用户名 8.function getusername() 9.{ 10.var WshNetwork = new ActiveXObject("WScript.Network"); 11.alert("Domain = " + WshNetwork.UserDomain); 12.alert("Computer Name = " + WshNetwork.ComputerName); 13.alert("User Name = " + WshNetwork.UserName); 14.} 15. 16.//取得系统目录 17.function getprocessnum() 18.{ 19. var pnsys=new ActiveXObject("WScript.shell"); 20. pn=pnsys.Environment("PROCESS"); 21. alert(pn("WINDIR")); 22.} 23.//返回系统中特殊目录的路径 24.function getspecialfolder() 25.{ 26. var mygetfolder=new ActiveXObject("WScript.shell"); 27. if(mygetfolder.SpecialFolders("Fonts")!=null) 28. { 29. alert(mygetfolder.SpecialFolders("Fonts")); 30. } 31.} 32.//取得磁盘信息 传入参数如：getdiskinfo('c') 33.function getdiskinfo(para) 34.{ 35. var fs=new ActiveXObject("scripting.filesystemobject"); 36. d=fs.GetDrive(para); 37. s="卷标:" + d.VolumnName; 38. s+="------" + "剩余空间:" + d.FreeSpace/1024/1024 + "M"; 39. s+="------" + "磁盘序列号:" + d.serialnumber; 40. alert(s) 41.} 42.//取得系统目录 43.function getprocessnum() 44.{ 45. var pnsys=new ActiveXObject("WScript.shell"); 46. pn=pnsys.Environment("PROCESS"); 47. alert(pn("WINDIR")); 48.} 49.//启动计算器 50.function runcalc() 51.{ 52. var calc=new ActiveXObject("WScript.shell"); 53. calc.Run("calc"); 54.} 55.//读取注册表中的值 56.function readreg() 57.{ 58. var myreadreg=new ActiveXObject("WScript.shell"); 59. try{ 60. alert(myreadreg.RegRead ("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\NeroCheck")); 61. } 62. catch(e) 63. { 64. alert("读取的值不存在！"); 65. } 66.} 67.//写注册表 68.function writereg() 69.{ 70. var mywritereg=new ActiveXObject("WScript.shell"); 71. try{ 72. mywritereg.RegWrite("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\MyTest","c:\\mytest.exe"); 73. alert("写入成功！"); 74. } 75. catch(e) 76. { 77. alert("写入路径不正确！"); 78. } 79.} 80.//删除注册表 81.function delreg() 82.{ 83. var mydelreg=new ActiveXObject("WScript.shell"); 84. if(confirm("是否真的删除？")) 85. { 86. try{ 87. mydelreg.RegDelete("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\MyTest"); 88. alert("删除成功！"); 89.} 90.catch(e) 91.{ 92. alert("删除路径不正确"); 93.} 94. } 95.} 96.//取得文件信息 调用方式如：getfileinfo('c:\\test.pdf') 97.function getfileinfo(para) 98.{ 99. var myfile=new ActiveXObject("scripting.filesystemobject"); 100. var fi=myfile.GetFile(para); 101. 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); 102.} 103.//取得客户端的信息 104.function clientInfo() 105.{ 106. strClientInfo="availHeight= "+window.screen.availHeight+"\n"+ 107."availWidth= "+window.screen.availWidth+"\n"+ 108."bufferDepth= "+window.screen.bufferDepth+"\n"+ 109."colorDepth= "+window.screen.colorDepth+"\n"+ 110."colorEnable= "+window.navigator.cookieEnabled+"\n"+ 111."cpuClass= "+window.navigator.cpuClass+"\n"+ 112."height= "+window.screen.height+"\n"+ 113."javaEnable= "+window.navigator.javaEnabled()+"\n"+ 114."platform= "+window.navigator.platform+"\n"+ 115."systemLanguage= "+window.navigator.systemLanguage+"\n"+ 116."userLanguage= "+window.navigator.userLanguage+"\n"+ 117."width= "+window.screen.width; 118. alert(strClientInfo); 119.} 120. 121.</script> 122. 123.//另存为excel文件并写入值 124.function saveas(){ 125.var ExcelApp = new ActiveXObject("Excel.Application"); 126.var ExcelSheet = new ActiveXObject("Excel.Sheet") 127.
