How can I read from a file on the client with Javascript?

John Zukowski

Basic security permissions don't permit this but, you can create an ActiveXObject FileSystemObject in IE to read, write, or append.

fs = new ActiveXObject("Scripting.FileSystemObject");
a = fs.OpenTextFile("c:	estfile.txt", 1, false);
For additional information on OpenTextFile, see http://msdn.microsoft.com/library/en-us/script56/html/jsmthopentextfile.asp. Users will be warned when this task is attempted.
