Question

I’m doing some Actionscript work right now and I’d like to know whether there’s a way to initiate an empty object’s value programatically like this:

var myObj:Object = new Object;

myObj.add("aKey","aValue");

To add a property called aKey whose value is aValue

I need to create a “Dumb” (data-only) object to use as a parameter to send via POST. So I don’t know offhand how long and/or how many attributes it’s gonna have.

Or something like that.

Thanks

ActionScript 3 allows you to create new Objects using an expressive Object Literal syntax similar to the one found in JavaScript:

const myObj : Object = {
    aKey: "aValue",
};
trace(myObj.aKey); // "aValue"

If you want to assign properties after the object has been constructed then you can use either dot notation or square bracket notation, eg:

const myObj : Object = {};  // create an empty object.
myObj.aKey = "aValue";
myObj["anotherKey"] = "anotherValue";

If you plan on sending the data over HTTP, you may wish to consider looking at the URLVariables class which will take care of URL encoding the data for you.
