Get value from Array using dynamic key in flex

Question

I have an array as follow.

var array:Array = new Array();
array["Circle"] = 1;
array["Rect"] = 2;

I wantto read the values by using a variable.

var key:String = "Circle";
trace(array[key]);

Can anyone guide me how to achieve this. Its not neccessary to go with Array only. I may switch to whichever collection in which this is possible.

What is it exactly that you would like to achieve. Do you want some code to loop over all key value pairs of your Map? — Dennis Jaamann

Use Object or Dictionary:

var obj:Object = new Object();
obj["Circle"] = 1;
obj["Rect"] = 2;

// alternative initialization - only for Object
obj = {Circle: 1, Rect: 2};

for (var key:String in obj)
{
    trace("key:", key, ",", "value:" obj[key]);
}

// output:
// key: Circle , value: 1
// key: Rect , value: 2

for each (var value:Object in obj)
{
    trace(value);
}

// output:
// 1
// 2
