This is achieved by using the Windows Script Host. First, create an instance of the object WScript.Shell. Then, use its Run method to execute the DOS command. For example, say your HTML page has a button that will run the DIR command when clicked. The onclick jscript function would look something like this:
-------------------------function btnDIR_onclick(){ var WshShell = new ActiveXObjec("WScript.Shell"); WshShell.Run("%comspec% /c DIR"); WshShell.Quit;}----------------------------
The %comspec% string in the argument for Run() specifies the path and file name of the command interpreter, Cmd.exe.
