本文介绍了一段使用JavaScript与ActiveXObject来获取指定路径下磁盘驱动器号的代码实现。通过调用`ShowDriveLetter`函数并传入磁盘路径参数，可以返回该磁盘的大写驱动器号。
<script language="javascript" type=text/javascript>
function ShowDriveLetter(drvPath)
{
var fso, d, s;
fso = new ActiveXObject("Scripting.FileSystemObject");
d = fso.GetDrive(fso.GetDriveName(drvPath));
s = "驱动器号 " + d.DriveLetter.toUpperCase( ) ; //toUpperCase( )字母转换为大写
return(s);
}
var drvPath="c://";
document.write(ShowDriveLetter(drvPath));
</script>
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script>
function ShowDriveLetter(drvPath)
{
var fso, d, s;
fso = new ActiveXObject("Scripting.FileSystemObject");
d = fso.GetDrive(fso.GetDriveName(drvPath));
s = "驱动器号 " + d.DriveLetter.toUpperCase( ) ; //toUpperCase( )字母转换为大写
return(s);
}
var drvPath="c://";
document.write(ShowDriveLetter(drvPath));
</script>
