Situation:-
I have created a installation setup(local) that returns a URL eg:- ved.test.com which is mapped to an IP 11.22.33.44.
Thus to make the web application accessible after installation, user has to make an entry in the hosts file under “C:\WINNT\system32\drivers\etc” directory explicitly.
Approach:-
After the installation application gets completed, application writes the file using Javascript.
Problem:-
Writing a File using Javascript is supported in IE. I need a Solution for Firefox.
Code used:-
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Write To A File</title>
<script language="javascript">
function WriteToFile()
{
/* The below statement is supported in IE only */
var fso = new ActiveXObject("Scripting.FileSystemObject");
var s = fso.CreateTextFile("C:\\Test.txt", true);
s.WriteLine('IE Supports Me!');
s.Close();
}
</script>
</head>
<body onLoad="WriteToFile()">
</body>
</html>

How to read and write into file using JavaScript
Kindly provide a solution that supports writing a file using Javascript that runs in Firefox browser.
Thanks in Advance.
You can’t do this, for hopefully obvious security reasons. JavaScript has no access to the file system…in IE it’s not JavaScript, but ActiveX doing this…it just has a JavaScript API exposed.
The problem isn’t that Firefox doesn’t do this…it’s that IE ever allowed it 🙂
