javascript - Self-references in object literal declarations -


is there way following work in javascript?

var foo = {     a: 5,     b: 6,     c: this.a + this.b  // doesn't work };

in current form, code throws reference error since this doesn't refer foo. is there way have values in object literal's properties depend on other properties declared earlier?

well, thing can tell getters:

var foo = {   a: 5,   b: 6,   c () {     return this.a + this.b;   } };  foo.c; // 11

this syntactic extension introduced ecmascript 5th edition specification, syntax supported modern browsers (including ie9).

the title says all. have add-in excel, written in c++, , register several different functions in excel call same extern "c" function in c++, dispatching on function called in excel. so, need able determine excel function called it. edit: since doesn't seem clear: have large plugin library excel, written in c++. extending it, , 1 of things want allow library support plugins itself, possibly written in other languages.
