Advanced JavaScript with Internet Explorer: Working with Drives and More

This series mainly concentrates on retrieving system information using JavaScript and displaying the same on a web page. All of the examples in this series can be directly tested by copying and pasting the entire code (of each section) in any text file with the extension .HTM and opening it using Microsoft Internet Explorer (preferably 5.5+).

The above code would automatically list all the physical partitions along with their ids and other information. To retrieve physical partition information, I used a built-in class, “Win32_DiskPartition.” The class internally has a lot of properties, methods and events. But, in the above example we concentrated only on the properties “DeviceID,” “BootPartition” and “Bootable” (related to “Win32_DiskPartition” class).

The “for” loop I used in the above code iterates for every physical partition present in the system and finally retrieves only the properties of that partition.
