4、fn.moveNext()res+=fn.item()+n;alert(res);二、IsRootFolder 屬性的學(xué)習(xí)Folder 對(duì)象的IsRootFolder 屬性用于判斷指定文件夾是否為根文件夾，如果是，則返回 TRUE，否則返回 FALSE。var FSObject = new ActiveXObject(Scripting.FileSystemObject);var sFolder=FSObject.GetFolder(c:);if(sFolder.IsRootFolder)alert(文件夾是根文件夾)elsealert(sF+文件夾不是根文件夾)三、Fol

7、者刪除等操作。如何創(chuàng)建file 對(duì)象？使用 file 對(duì)象對(duì)指定文件的屬性進(jìn)行，首先必須創(chuàng)建 file 對(duì)象，該對(duì)象可以通過(guò) FSO 對(duì)象的 getfile()方法來(lái)創(chuàng)建。語(yǔ)法：FSObject.GetFile(filename)；例如：五、File 對(duì)象的屬性介紹File 對(duì)象的屬性與folder 對(duì)象的屬性基本相同，只是其功能針對(duì)的不是文件夾，而是文件。顯示文件屬性.style1屬性說(shuō)明Attributes設(shè)置或返回指定文件的屬性DateCreated返回指定文件被創(chuàng)建的時(shí)間和日期DaastAcsed返回指定文件最后被的時(shí)間和日期DaastModified返回指定文件最后被修改的時(shí)間和日期
