Hi Diego,
in my test cases your example does not work.
At the same time, I am not sure you have to put the image in the DOM, before
the event could be called.
If you need to do it, the evaluation will be async, so as globalEval
replacement, it is not that good.
If not, you are still evaluating "whatever" inside a function and, as you
know, this simply means that if you have a global scope variable, called
arguments, you will never be able to use it as is, unless you specify the
global object as prefix (window or self, because this will be the image
itself)
I wonder why you are still looking for a globalEval alternative. What I mean
is: which kind of problem has the current solution?
I would like to know it and try to fix it, if it is possible, since "I feel
a bit responsible" for that code :-)
Regards
