Can anyone think of a way to pass the value of a variable, not a
reference to that variable (since the value of the variable might
change after the AJAX request is sent) to an anonymous function
defined for a success callback for AJAX? Or, is the only way to do
this to have my /ajax/asset/insert callback return this ID back to me
in the JSON response?
Thanks,
Rob
