Get item/variable from array with string AS3

Question

so I have an array with 4 string values in it (defined before array like public var p1:String etc)

public var partArray:Array = 
[
    p1 = ""
    p2 = ""
    p3 = ""
    p2_3 = ""
];

Lets say I have a textbutton with the name of one of these variables, how would I get the correct variable from the array using the name of the textbutton.

First of all, in AS3 it's not recomended to create associative arrays like this. For key:value maps use an Object (for example {key: "value"}) or a Dictionary.

With any container object you can lookup properties using array access brackets:

trace(myMap[key])

With an Array the key is an integer, with an Object the key is a string, and with a Dictionary the key is anything.

So to lookup a value by another object's name you might use:

myMap[myButton.name]
