In the early stage, when the system was operated under .net, it was very complicated to implement the same function. I didn't expect it to be so simple using JavaScript, so I searched for the code on the Internet and improved it.

Copy code The code is as follows:

function PathList(path) {
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fldr = fso.GetFolder(path);
var fd = new Enumerator(fldr.SubFolders);
for (; !fd.atEnd(); fd.moveNext()) {
sd = fd.item();
WScript.Echo(sd.path);
//写入文件
writeFile("a.text",sd.path);
//document.write(sd.path);
PathList(sd.path);
}
}
function FileList(path) {
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fldr = fso.GetFolder(path);
var fd = new Enumerator(fldr.SubFolders);
for (; !fd.atEnd(); fd.moveNext()) {
sd = fd.item();
var fc = new Enumerator(sd.files);
for (; !fc.atEnd(); fc.moveNext())
{
WScript.Echo(fc.item());
writeFile("B.text",fc.item());
}
WScript.Echo(sd.path);
//写入文件
writeFile("a.text",sd.path);
//document.write(sd.path);
FileList(sd.path);
}
}
//当前目录文件
function CurFileList(path) {
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fldr = fso.GetFolder(path);
var fc = new Enumerator(fldr.files);
for (; !fc.atEnd(); fc.moveNext())
{
WScript.Echo(fc.item());
writeFile("c.text",fc.item());
}
}
/*
object.OpenTextFile(filename[, iomode[, create[, format]]])
参数
object
必选项。object 应为 FileSystemObject 的名称。
filename
必选项。指明要打开文件的字符串表达式。
iomode
可选项。可以是三个常数之一:ForReading 、 ForWriting 或 ForAppending 。
create
可选项。Boolean 值,指明当指定的 filename 不存在时是否创建新文件。如果创建新文件则值为 True ,如果不创建则为 False 。如果忽略,则不创建新文件。
format
可选项。使用三态值中的一个来指明打开文件的格式。如果忽略,那么文件将以 ASCII 格式打开。
设置
iomode 参数可以是下列设置中的任一种:
常数 值 描述
ForReading 1 以只读方式打开文件。不能写这个文件。
ForWriting 2 以写方式打开文件
ForAppending 8 打开文件并从文件末尾开始写。
format 参数可以是下列设置中的任一种:
值 描述
TristateTrue 以 Unicode 格式打开文件。
TristateFalse 以 ASCII 格式打开文件。
TristateUseDefault 使用系统默认值打开文件。

//读文件
function readFile(filename){
var fso = new ActiveXObject("Scripting.FileSystemObject");
var f = fso.OpenTextFile(filename,1);
var s = "";
while (!f.AtEndOfStream)
s = f.ReadLine() "n";
f.Close();
return s;
}
//写文件
function writeFile(filename,filecontent){
var fso, f, s ;
fso = new ActiveXObject("Scripting.FileSystemObject");
f = fso.OpenTextFile(filename,8,true);
f.WriteLine(filecontent);
f.Close();
//alert('ok');
WScript.Echo("写入成功");
}
//删除文件
function deleteFile(filename,filecontent){
var fso, f, s ;
fso = new ActiveXObject("Scripting.FileSystemObject");
f = fso.GetFile(filename);
f.Delete();
//alert('ok');
WScript.Echo("删除成功");
}
//批量删除,未删除文件夹,删除不了当前目录文件
function DelFileList(path) {
var fso = new ActiveXObject("Scripting.FileSystemObject");

//写入文件
writeFile("a.text",sd.path);
writeFile("a.text","删除完毕");
//document.write(sd.path);

}

//删除当前目录文件
function CurDelFileList(path) {

var fldr = fso.GetFolder(path);
var fc = new Enumerator(fldr.files);
