When the scriptData is as follow:
jQuery('#uploadify').uploadifySettings('scriptData',{
'a' :'A & B',
'b' :'B & C',
'c' :'C & D'
});
The script in the flash will get some error.
function __flash__addCallback(instance, name) {
instance[name] = function () {
return eval(instance.CallFunction("" + __flash__argumentsToXML(arguments,0) + ""));--unknown exception
}
}
