oi JAIME!!
you cannot. coldfusion is a serverside language. Javascript is a clientside. You
will need to pass the values from the client to the server. Then you can use
them how you wish.

The only thing you can do is use Javascript to get the resolution and then
stick it into a variable ... that may work.

I agree technically it should not work as one side is client, the other server,
but on my test page it does present the js result value instead of the text
string. Cfdump shows text strings, but within cfoutput tags seems to work
showing the js results. A fluke :)
I tried the form post option,
Dang, you're right, I didn't look at the source, just the page. Browser has it,
cf doesn't. So ajax post is prob best solution, form post test works but not

Glad you worked it out.
One thing you should do is make sure a session variable exists before using
the session variables.
When I first loaded the page I received an error, after I refreshed the
error went away.
You should cfparam the variables to a default first, otherwise they wont be

This method won't work either, because the Ajax function will be executed after
the output of the page is already on client side.
This is why you get an error at the first call. So you have to call the

Add code in your Application.cfc onSessionStart() method, that makes sure
the default session variables exist right when the session starts.
You can also test for the session in onRequestStart() ,and call the

The problem is not with using POST or GET, the problem is using Ajax.

One thing you may want to consider is giving the user an option. Sometime the
user doesn't want your mobile version even though they are mobile. I find
sites all the time where I'm given a mobile website that doesn't work as well
as the desktop version. Sometimes even when they give me the opt
Good point.
A simple unobtrusive way to do this is to provide a "Desktop Version"
link in the footer of the mobile version which resets the session vars
to desktop.

The website is the desktop version which adjusts nicely in the Zurb Foundation
grid framework for phones.
Only thing I'm doing is loading smaller size jpg images. Same proportion image,
but smaller width hence smaller file size/faster download.
For tablets desktop version looks/works fine.
I use css media queries for layout, or more recently Zurb Foundation or Twitter
Bootstrap, the former is much more elegant/intuitive grid, but Bootstrap has
sexier looking eye candy ref buttons.
However in this instance I need to load smaller set of jpgs for a slider viewed
on a phone. jpg img
Good idea, all it requires is a reset of the screensize session vars from the

My approach at the moment is coding responsive pages. Have any of you found a

Actually I can respond to id's and classes based on screen size via css media

The page loads but reloads immediately sending the values in the same time.

Now, the trick I gave was only to deal with the specific problem as you defined
it, but there would be an even better solution.
I suppose the user has to go through some other page before he gets images.

May be, but the point is still that when Ajax does it, the page that needed the

For sending data to the server, there is still good old FORMs.

The best would be to save it while still on the server from the cfc.
But you must make sure the session Id is transmitted to the cfc, otherwise it
will define a new session.
That's why the WURFL project is the best option, you can also scale the
layouts you use as well.
