Accessing Object and Property via Variable?

Question

I have a namespace setup like

mySpace.util = {

    valid: {

          first: function() {
               //blah
          }

    }

}

I am trying to pass the valid and first as variables to access the function ? I've tried:

mySpace.util.[variable1[variable2]()] but that doesn't work ? I am trying to pass variables so I get mySpace.util.valid.first()

Any ideas how I could do this?

Answer 1

var obj = 'valid',
    meth = 'first';

mySpace.util[obj][meth]();
