Get javascript array object from its name

Question

In javascript I have an array of strings in which each string is name of another array.
How can I get each array object from its name?
In my example I need to get cavaSel array from its name which is contained in array CaveTipo

for (var i = 0; i < CaveTipo.length; i++) {
    var cavaSel = $(CaveTipo[i]);
    for (var t = 0; t < cavaSel.length; t++) {
        ///
    }
}

By 'name' I'll assume you mean 'identifier'.
For example: say you have 'identifier' CaveTipo to reference the following example array:

var CaveTipo=[ 'my_array_a'
             , 'my_array_b'
             , 'my_array_c'
             ]
; //end var

Above example array, contains strings which are the identifiers of other array's, for example:

var my_array_a=[ /* data */ ]
,   my_array_b=[ /* data */ ]
,   my_array_c=[ /* data */ ]
; //end var

Now in order to use the identifier (strings) in CaveTipo one should use bracket-notation on the object that holds the target-arrays: namespace[/*identifier*/] (instead of dot-notation).

If that namespace was global, then you'd use window (or self ): window[/*identifier*/] .

var cavaSel, i, t;
for (i = 0; i < CaveTipo.length; i++) {
    cavaSel = window[ CaveTipo[i] ];
    for (t = 0; t < cavaSel.length; t++) {
        ///
    }
}

Now let's assume the array's are inside an object you created (in global):

var caveData={ my_array_a: [ /* data */ ]
             , my_array_b: [ /* data */ ]
             , my_array_c: [ /* data */ ]
             }
;

var cavaSel, i, t;
for (i = 0; i < CaveTipo.length; i++) {
    cavaSel = caveData[ CaveTipo[i] ];
    for (t = 0; t < cavaSel.length; t++) {
        ///
    }
}

This last approach is better in most cases since it either frees up namespace usage in global (for my_array_X ) OR provides an identifier to the object within 'private' closures.
