Accessing a multidimensional array using a one dimensional array in Javascript

Question

If I have the following initialized... (fyi, in the code I'm basing it off of, both variables are dynamically created)

// Start of Code that MUST stay unchanged.
var myPrimaryArray = [["Potato","Walrus"],42,[["Your father was a hamster", "Target"],362]];
var locationArray = [2][0][1];
// End of Code that MUST stay unchanged

//What to put here to get "Target"?

How do I make this return "Target", with only those two variables? (Not knowing the depth into either array I have to go ahead of time.)

I appreciate the updated answer, but you're still changing one of the initial vars, sorry if I'm unclear, ... the point is those are the initial vars I have to start out with. Both those vars will be dynamically generated, which is why I can't change them. As such, this assumes I don't actually know what the value in location array will actually be, or the actual layout of myPrimaryArray. All I know is that location array holds the position of where in myPrimaryArray "Target" is. If I could do something like "MyNewVar = myPrimaryArray[locationArray] that'd be great, but I don't think it works. — lilHar

Hopes this will return target

var myPrimaryArray = [["Potato","Walrus"],42,[["Your father was a hamster", "Target"],362]];
var locationArray = myPrimaryArray[2][0][1];
alert(locationArray);

output:

Target

To be fun , check your Code:

locationArray = myPrimaryArray [2][0][1];

I appreciate the suggestion, but the code I'm providing is what I have to work with (it's an example of something I can't really change). The point is that I have to get "Target" from myPrimaryArray using locationArray as its provided. Changing the locationArray isn't an option for me.

That's cool, my English is pretty rubbish at times too, and it's my first language!

Got a solution (altered text for stackoverflow, hope it still works for anyone seeking a solution similar to mine.) It's cumbersome, but it should work.

// Start of Code that MUST stay unchanged.
var myPrimaryArray = [["Potato","Walrus"],42,[["Your father was a hamster", "Target"],362]];
var locationArray = [2][0][1];
// End of Code that MUST stay unchanged


getArrayObjectWithLocationArray(myPrimaryArray,locationArray)



function getArrayObjectWithLocationArray(myArray, myLocationArray){
var myArray = stringToPositionArray(myString);
if (myLocationArray.length > 1}{
    return getPanelWithPositionString([myArray[myLocationArray[0]], myLocationArray.splice(0,1))
} else {
    return myArray[stringToPositionArray[0]];
}

}
