返回连续十进制数字,用于唯一标识磁盘卷。
object.SerialNumber
object 为 Drive 对象。
可以使 SerialNumber 属性来确保在带有可移动媒体的驱动器中插入正确的磁盘。
下列代码阐明了 SerialNumber 属性的用法:
function ShowDriveInfo(drvpath){
var fso, d, s, t;
fso = new ActiveXObject("Scripting.FileSystemObject");
d = fso.GetDrive(fso.GetDriveName(fso.GetAbsolutePathName(drvpath)));
switch (d.DriveType)
{
case 0: t = "Unknown"; break;
case 1: t = "Removable"; break;
case 2: t = "Fixed"; break;
case 3: t = "Network"; break;
case 4: t = "CD-ROM"; break;
case 5: t = "RAM Disk"; break;
}
s = "Drive " + d.DriveLetter + ": - " + t;
s += "<br>" + "SN: " + d.SerialNumber;
return(s);
}
