to get a string from a notepad and use it in html

[shwetakannur]

How do I get a string (randomly generated, but I do know the next line) from a .txt file and use it in html?

I want to know how to extract a string from a file(text file) using javascript?

Here is an example from the WSH help file which is downloadable from Microsoft.

Code: Select all

function GetLine()
{
   var fso, f, r;
   var ForReading = 1, ForWriting = 2;
   fso = new ActiveXObject("Scripting.FileSystemObject");
   f = fso.OpenTextFile("c:testfile.txt", ForWriting, true);
   f.WriteLine("Hello world!");
   f.WriteLine("JScript is fun");
   f.Close();
   f = fso.OpenTextFile("c:testfile.txt", ForReading);
   r =  f.ReadLine();
   return(r);
}

Hi shwetakannur,Strictly speaking, you can't, because JavaScript/JScript has no way of directly accessing a file system (and neither does VBScript). However, as jvierra pointed out, if you are running your script in a trusted fashion (i.e., from an HTA or from a WSH script), you can use the FileSystemObject COM object to open and read from a text file.Bill

Hah - ust thought of another unique way to understand this message:

The original post is for "jscript" and "notepad". Perhaps the user wants to read from an open notepad instance and convert it into html using jscript. Of course the reference to Javascript adds more confusion along with the request for "randomly generated".

Is it possible that there is some kind of random string generator used for passwords or validation that produces output visible in notepad??? It would be a plain text file in any case.

No matter how I look at this request I can't make head nor tail of the question. Hmmm.
