If test1 is a global variable you can access it by name through the window object:

window[theArrayOfStrings[0]].foo();   // test1();

If it's not, eval is the only way, but I'd strongly advise avoiding eval in all circumstances. Using a lookup as in J-P's answer (+1) is much much more appropriate than selecting variable names.
