Actually, I'm pretty sure the answer is: you can!
Attached is a working example I just put together (with comments) showing
you how to use WDDX to pass variable data from JavaScript to ColdFusion and
back again:
<<wddx_example.cfm>>
And here are the files from the WDDX SDK that are required to make the
script above work:
<<wddx.js>> <<wddxDes.js>>
Hope this helps!
