[webkit-help] how to implement event listener

[上田耕一]

Dear Ryosuke Niwa

Thank you for precise advice.
I succeeded in reading "Struct" by using "Dictionary".
However, I do not succeed in reading "Struct" in "Struct".
"aaa" of the following sample is readable, but does not understand a method
to read "bbb".
Please tell me if I know a method to read "Struct" in "Struct".

-----------------
HTML

var param = {
yyy : {
bbb : 1,
},
aaa : 0x006,
};
xxxEvent.boolean addXXXEventListener( param, firedeve);

-----------------
