Setting Actionscript Object Keys

问题

If I have an array, I can set the keys by doing the following:

var example:Array = new Array();

example[20] = "500,45";
example[324] = "432,23";

If I want to do something with Objects, how would I achieve this?

I tried the following:

var example:Object = [{x:500, y:45}, {x:432, y:23}]; // Works but keys are 0 and 1

var example:Object = [20: {x:500, y:45}, 324: {x:432, y:23}]; // Compile errors

var example:Object = [20]: {x:500, y:45}, [324]: {x:432, y:23}; // Compile errors

var example:Object = [20] {x:500, y:45}, [324] {x:432, y:23}; // Compile errors

Is there a good way to achieve this?

I understand I could do this:

var example:Object = {id20 : {x:500, y:45}, id324: {x:432, y:23} };

But it doesn't suit me.

回答1:

The [] notation has the same meaning of doing a new Array() so when you are doing:

var example:Object = [{x:500, y:45}, {x:432, y:23}];

you are in fact creating an array with two elements who are object {x:500, y:45} and {x:432, y:23}.

If you want to create an object with key 20 and 324 use the {} notation who is the same a new Object()

So your example became =>

var example:Object = {20: {x:500, y:45}, 324: {x:432, y:23}};

You can do the same as your first example using an Object instead of an Array:

var example:Object = new Object();

example[20] = "500,45";
example[324] = "432,23";
