Is there a way to access a javascript variable using a string that contains the name of the variable?

Given:

var x = {
    myproperty: 'my value'
};

You can access the value by:

var value = x['myproperty'];

If you're looking for a global variable, then you would check its container (window);

var value = window['x']['myproperty'];

You can use

eval(variableString);

Proceed with caution as many don't recommend using eval()

If it is a global variable named myVar, you can use:

window["myVar"]

The eval function can access a variable from a string containing the variable's name.

eval('baseVariableName'+index) = 'something';
