Read Text file using Javascript [duplicate]

Question

Could you please tell me whether there is any way of reading and displaying the value from the text file using Javascript when I open the HTML page?

The file is in the local system and it needs to be picked up automatically when the HTML page opens up and the result should be displayed in alert message as well as in the HTML page.

Not possible. The user has to at least select the file in an <input type="file" /> element. — Sirko

@Sirko can't we specify the file name and its location instead in the JS? — Sophia Sutter

If you could do it completely automatic, you could read any content from a user's harddrive: passwords, private files, ... If you need "permanent" storage on a client's computer look at cookies and localStorage. — Sirko

See similar question, it is NOT possible to load local files using plain javascript.

However, we can use HTML5 file APIs to facilitate the loading of user specified files.

I got the answer for this

   var fso = new ActiveXObject("Scripting.FileSystemObject");
  var ForReading = 1;
  var f1 = fso.OpenTextFile("c:\\file.txt", ForReading);
  var text = f1.ReadAll();
  f1.close();
  alert( text);

Thanks for your help

Be careful, because this will only work in Internet Explorer.
