I looked at other materials, including CPU extraction and Mac off-the-shelf. Code But there is no hard disk serial number. After searching for a long time, we can find the parameter for extracting the hard disk serial number. So I made it up.
<HTML>
<Head>
<Title> extract the hard drive serial number </title>
<SCRIPT>
Function disk () {// hard disk serial number
VaR locator = new activexobject ("wbemscripting. swbemlocator ");
VaR service = locator. connectserver (".");
VaR properties = service. execquery ("select * From win32_diskdrive ");
VaR E = new enumerator (properties );
Document. Write ("<Table border = 1> ");
For (;! E. atend (); E. movenext ())
{
VaR P = E. Item ();
Document. Write ("<tr> ");
Document. Write ("<TD>" + P. Signature + "</TD> ");
Document. Write ("</tr> ");
}
Document. Write ("</table> ");
}
</SCRIPT>
</Head>
<Body>
<Input type = "button" value = "hard disk serial number" onclick = "disk ()">
</Body>
</Html>

For ASP or. net users, through ASP or. net Language to obtain client hardware information is very familiar. but how can I obtain client information through a client script such as JavaScript? See the following example:

The main advantage of using JavaScript to obtain client information is that you do not need server resources, you do not need to refresh the webpage, And you can directly execute scripts on the client for display.

The hard disk serial number parameter is found here:
\ 'Obtain the hard disk serial number
Dim cmicwmi as new system. Management. managementobjectsearcher (\ "select * From win32_diskdrive \")
Dim uint32 as uint32
For each cmicwmiobj as managementobject in cmicwmi. Get
Uint32 = cmicwmiobj (\ "signature \")
Next
Textbox1.text = uint32.tostring
And finally proposed in one piece, huh, huh.
