Hi,
I am running a javascript code,where i am taking a file from the local disk and then trying to open or read the file. Javascript code is as follow:

JavaScript

var CSVfilepath = prompt("Enter the path of CSV file","D:/BlackPanther/LudhiyanakOL.csv");
var ReadCSVfile = new file(CSVfilepath);
ReadCSVfile.open(CSVfilepath);
ReadCSVfile.readln();

I am getting error in var ReadCSVfile = new file(CSVfilepath) that file is undefined.
Why i m getting file undefined message?

Any help would be appreciated.

Thanks.

XML

var CSVfilepath = prompt("Enter the path of CSV file","D:/BlackPanther/LudhiyanakOL.csv");
var ReadCSVfile = new file(CSVfilepath);

I doubt if you can access files like this in Javascript. Due to security reasons direct access to files are not supported.

Possible alternative to access file from Javascript are ActiveX, Silverlight, Flash, etc.

Further, if you want to access some data from files stored on the server then you can use XMLHttpRequest to get back the contents of that file.
