javascript reflection ?

[Edward Chen]

how to use javascript relection in an AJAX call ?

var people = ... // data from Ajax call
alert (people.firstName); // it works

could I use some javascript reflection to invoke that method, like java reflection.. ?

Object.invokeMethod(people, "getFirstName");

Thanks.

I assume firstName is a property. What method is there to invoke?

P.S. As a functional language, JavaScript has no methods -- though we frequently call functions that are properties of objects a "method" (even though they're really not).

Yes, it is a property. Assume we need to write a tool to dynamically get an object property in the runtime. How could we do it in the JS ?

Thanks.

Still not sure what you are asking. To access a property, you just reference it.

Or are you looking for a way to discover what properties an object has? If so, check out the for...in statement.

Edward,
Do you mean something like this:

people["firstName"]

i'm not clear about your question.
but i suggest you to research "js & class".
there may some useful articles for you.
