Write to file question

[von]

I am trying to write a single piece of data (that is generated from a
Javascript) to a text file on my server via a Perl script.

The Javascript is setup so that I can display the required data on my
website using the following HTML:

<span name='Data1' class='data1'></span>

But I need it sent to a text file. :(

I have tried using the following code (thanks to saxifrax) to send the data
to a Perl script:

var i=new Image();
i.src="http://www.mydomain.co m/cgi-bin/write.pl?" + span;

But it doesn't return anything.

If I test my Perl script with this:

var i=new Image();
i.src="http://www.mydomain.co m/cgi-bin/write.pl?" + "test";

Then it returns the word "test" - so I know the Perl script is working.

When I try this:

var i=new Image();
i.src="http://www.mydomain.co m/cgi-bin/write.pl?" + allSpans;

Then it returns "Object" - whatever that means.


Anyone have any advice on how to get the data sent to my Perl file?

Thanks :)

Not quite clear where that "Object" is coming from...but this is
unclear:

We can't see how the JS is 'setup' - a key factor. Is a text string
being displayed within that span? If so, you can give it an id
(="Data1") - spans don't take names as attributes - and use:

var el, txt;
if (el = document.getEle mentById('Data1 ')
&& (txt = el.firstChild))
{
var i = new Image;
i.src = 'http://www.mydomain.co m/cgi-bin/write.pl?' + txt.nodeValue;
}
