The hasOwnProperty method available in all objects does exactly this.

Why it is called hasOwnProperty rather than hasProperty I have no idea.

i use hasOwnProperty in the function i posted but i can only use it to check
immediate properties. it doesn't support nested properties, for example
var obj:Object = new Object();
obj.apple = new Object();
obj.apple.color = red;
// hasOwnProperty doesn't support nested properties
var b1:Boolean
Oh. My bad - should read the entire thread first before posting.
I had a similar need, and ended up doing it in a loop like you did,
mainly because from the languages I've used before, exceptions tend to
be 'expensive' in terms of computation time. Not sure what the case is
with AS3.

I have a PHP statement that I am trying to write in AS3. So far it errors

rewrite this for AS3? Here is the statement:
// at the time this is run this.language_data is an object with 2
properties
// the STYLES property does not
I don't like to know if there is an easier way to do this so I wrote this
function to check if a object or the requested properties exist on the
object.
// call it like this
isset_drilldown(this.language_data,'STYLES','BRACKETS',0);
// Determine whether a variable set via a drill down through
er sorry for the php references. i am knee deep in translating php code. :P
