Re: Java Script Value to CF Value
That script won't work, as the CF code will already be executed before the client-side Javascript does anything. CF might be able to write to Javascript but can't read it.

Re: Java Script Value to CF Value
Robert, I couldn't really get a feel for what you're doing but take a look at two options: 1) Doing an XHR called (Ajax) to a CF template to set it and do any work necessary. 2) Look into WDDX to help you exchange JS native data elements between CF. http://www.webmonkey.com/webmonkey/99/15/index3a_page4.html?tw=authoring Rey...

Re: Java Script Value to CF Value
But that is for passing CF values into Javascript, isn't it? Robert is trying to get a client-side JS value (which is defined once an image has loaded) into the server-side CF code. Can't be done in that way. Robert, what is it you're trying to do in general, aside from the snippet of code you gave?

Man, just do an ajax call with your client side variable as a url parameter (or post if you want to get fancy) and have CF process that and save it as a var...

Re: Java Script Value to CF Value
Yep, that's possible - if you're using CF8 there are tags/functions to do this, if not you could use Rick Root's excellent ImageCFC or Alagad Image Component. For info, Railo has a very handy attribute which lets you get image dimensions directly from a cffile action=info file=... tag.
