Re: [flexcoders]How would you rewrite this isset PHP condition in AS3?
The hasOwnProperty method available in all objects does exactly this.
http://livedocs.adobe.com/flex/3/langref/Object.html#hasOwnProperty()
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 = obj.hasOwnProperty(apple.color); // returns false
var b2:Boolean = obj.hasOwnProperty(banana.color); // returns false
var b3:* = typeof(obj.apple.color); // returns string
var b4:* = typeof(obj.banana.color); // Error #1010: A term is undefined and
has no properties.

Re: [flexcoders]How would you rewrite this isset PHP condition in AS3?
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.

Re: [flexcoders]How would you rewrite this isset PHP condition in AS3?
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 the properties
// instead of this: isset(this.language_data['STYLES']['BRACKETS'][0])
// you would use this:
isset_drilldown(this.language_data,'STYLES','BRACKETS',0)
// parameters are - object [, property[, ...]]
public function isset_drilldown(variable:*, ...properties):Boolean {
if (variable!=null variable!=undefined) {
var length:int = properties.length;
if (properties.length0) {
var reference:* = variable;
for (var i:int=0; ilength; i++) {
var property:String = properties[i];
if (Object(reference).hasOwnProperty(property)) {
reference = reference[property];
}
else {
return false;
}
}
}
return true;
}
else {
return false;
}
}
