复制代码 代码如下:

function ReportFileStatus(filespec)

{

var fso, s = filespec;

fso = new ActiveXObject("Scripting.FileSystemObject");

if (fso.FileExists(filespec))

s += " exists.";

else

s += " doesn't exist.";

return(s);

}

采用客户端的 FileSystemObject 对象

例：

复制代码 代码如下:

function check()

{

var fso;

fso = new ActiveXObject("Scripting.FileSystemObject");

if( fso.FileExists("c:testfile.txt"))

{

alert("Exists!");

}

else

{

alert("not Exists!");

}

}
