Using JavaScript variables with Coldfusion

[powahusr]

I would like to use variables that I create in Javascript, for use outside the <script></script> tags.


Through the use of Javascript, say I want to get the &quot;screen.width&quot; value of the current browser, what would I have to do to use that value in my Coldfusion &quot;OUTPUT&quot; tag.


Example:


I would like to get the value of the width of the screen

<script type=&quot;text/javascript&quot;>
document.write(screen.width)
</script>


And use it here

<cfoutput>
Display Screen width here
</cfoutput>

CF executes server-side, long before the user's browser runs it's javascript.

If you want to expose the variable to CF then you need to get the clients screen width, and then make another call to the server with that value as a parameter.
