Hi
This question has probably been answered a few times on this and other
news groups, so it is worth doing some searching on this news group or
<URL:http://www.webdeveloper.com/forum/forumdisplay.php?s=&daysprune=30&forumid=3>.
>From my amateur knowledge, reading a text file may be achived through
the following (depending on security settings):-
1. XMLHttpRequest object
If you set the URL to a local file name, you can access the contents
through the "responseText" property.
This is probably the most cross-browser method.
2. Active X - "Scripting.FileSystemObject"
This is an ActiveX object provided by Microsoft. It is only available
for browsers which support ActiveX, and have the
"Scripting.FileSystemObject" object installed on the client.
As far as I am aware you should find that "Scripting.FileSystemObject"
is commonly already installed on Windows clients.
Example:-
var FSO = new ActiveXObject("Scripting.FileSystemObject");
var nForReading=1;
var oFileObj = FSO.OpenTextFile(sFileName,nForReading, false);
var sFileContents=oFileObj.ReadAll();
oFileObj.Close();
3. XPCOM - Firefox Only
Firefox has XPCOM components. See an example for reading a file at the
bottom of the following page:-
