DTHML Question
This may be a dumb question, but how do you allow a user to change the content on a page?
I have a page that uses data from a cookie. I want the user to be able to edit the cookie-based data if necessary, but I don't want to have to reload the ASP page (fewer DB calls, etc.), just change the text on the page that was originally created from the cookie.

Depending on the browser the page can be changed through JavaScript...If you got a little more specific it would make things a bit clearer to see what you mean.

Even though this doesn't use cookies, I think this I can take it from there. Say I had something like this:
<HTML>
<SCRIPT language="javascript">
function WrtieNewStuff()
{
write some new text
}
</SCRIPT>
<BODY>
The old stuff. <a href='javascript:WriteNewStuff();'>Click to write new stuff</a>
</body>
</HTML>
When the user clicked the link, the link would call the WriteNewStuff function and write some text or HTML. How do I preserve what is already on the page (ie "The old stuff") where the page reads "The old stuff. The new stuff".

the only way to preserve it is if it was being loaded from the database. or write another cookie to preserve it.

You can store the old text in a variable:
Code:
...
<script LANGUAGE = "JavaScript">
var oldStuff;
function writeNewText(strNewText){
oldStuff = document.all.varText.innerText;
document.all.varText.innerText = strNewText;
alert(oldStuff + ' ' + '\nWas saved!');
}
</script>
...
<p ID = "varText">This text is old</p>
...
<a HREF = "JavaScript:writeNewText('This text is new');">Write new text</a>

Of course, once the variable goes out of scope, you lose any saved values. To persist the values you'd have to use cookies or a db.
