Post subject: innerHTML issue
Archived from groups: alt>www>webmaster (more info?)
We have a web site where printer-friendly pages are generated on the fly by
using the following JavaScript:

<script language="javascript">
function PrintThisPage()
{
var sOption="toolbar=yes,location=no,directories=yes,menubar=yes,";
sOption+="scrollbars=yes,width=750,height=600,left=100,top=25";

var sWinHTML1 = document.getElementById('content').innerHTML;

var winprint=window.open("","printer",sOption);
winprint.document.open();
winprint.document.write('<html><body><h1>Our Web Site - Printer
friendly version</h1>');
winprint.document.write(sWinHTML1);
winprint.document.write('</body></html>');
winprint.document.close();
winprint.focus();
}
</script>

This generates a new version of the page using only content defined between
div elements ie <div id=content> and </div>. Everything else is ignored.

The new page is called with <a href="javascript:PrintThisPage();" >Printer
Friendly Version</a>

Everything worked in all browsers tested... until we "encrypted" our e-mail
addresses. Now the Printer Friendly facility only works in IE and Opera, but
not in Netscape and Mozilla.

The "encrypted" e-mail addresses are in the format:

<script language="JavaScript">
<!--
var name = "my.name";
var domain = "mysite.co.uk";
document.write('<a href=\"mailto:' + name + '@' + domain + '\">');
document.write(name + '@' + domain + '</a>');
// -->
</script>

It seems there's a clash with the document.write statements in the source
page that IE and Opera can handle, but Netscape and Mozilla cannot.

Can anyone throw any light on this issue?

The page is already being dynamically created with javascript. Don't
obsfucate your email addresses.

Grey, thanks. Yes the printer-friendly page is being created dynamically
from the published source page. We don't want e-mail addresses harvested so
the addresses in the published source page are obsfucated. That's the
problem. Regards, Carl

Hi Herc, thanks. I'm not a JavaScript whizz. Give me a clue how this would
be done. Regards, Carl

See where you used innerhtml here to READ between the DIV and /DIV

var sWinHTML1 = document.getElementById('content').innerHTML;


Works the other way aswell. This is how drop down menus dynamically change the screen.
Sounds like you'd have to nest your DIV sections.

function setemails() {
document.getElementById('emails').innerHTML = '<a href=\"mailto:' + name + '@' + domain + '\">'
+ name + '@' + domain + '</a>'
}

<body onload="setemails()">
....
<div id='content'>
....
<div id='emails'></div>
...
</div>


Once its loaded it will insert HTML inside the empty div. I'm not sure how it helps
the bots run write and javascript aswell you know.
