writing to a .txt file

[mackey333]

what i am trying to do is pretty hard to explain so here is a simplified example of the problem:

i need to clear a text file, write to it, and then be able to read from it...so say someone puts there name in a text box and hits submit, the current stuff in the text file is cleared, the new name is writen to it, and then it is saved (kind of like a server side cookie)...then on a different page, i need to somehow get the text into a javascript variable...i relieze this would probably be easier with a database, but i am on a free server that doesnt support them...i'm guessing there should be a jscript or vb way to do this...thanks for any help... -Greg :-Q

hi Greg
write to files? on client? do you think it's possible without some warning to the user about security violations?

that server doesn't support ANY server side language?

i think it might be done in vbscript, but i'm not vb..~er Victor

If the server allows you to run CGI scripts, then you could use a script to dynamically create the Javascript and HTML for a page. Example:

#!perl
use CGI qw( :all );
use CGI::Carp qw( fatalsToBrowser );

my $foo = param( 'foo' );

my $javascript = qq[
    var dynamicValue = "$foo";
];

print header;
print start_html( -script => $javascript, -onLoad => "alert( dynamicValue )" );
print end_html;

As for the original form, you would have an input button with name property of 'foo', and the form 'action' should point to the CGI script. Note that you can write a more complicated version of the above script that acts as the empty form, as well as the filled one.

Hope this helps, Neil ;-)
