JS实现打开本地文件或文件夹 ActiveXObject

IE浏览器打开C盘，测试可用。

如果浏览器报错提示：ActiveXObject is not defined

Internet 选项 -> 安全 - >安全级别,调低级别

function openFileIIs(){
try{
var obj=new ActiveXObject("wscript.shell");
if(obj){
obj.Run("c:/", 1, false );
//obj.run("osk");/*打开屏幕键盘*/
//obj.Run('"'+filename+'"');
obj=null;
}
}catch(e){
alert("请确定是否存在该盘符或文件");
}

}
openFileIIs()

avascript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);

//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.ActiveSheet.Cells(1,1).Value = "This is column A, row 1";
ExcelSheet.SaveAs("C:\\TEST.XLS");
ExcelSheet.Application.Quit();
