dynamically generate function in object

Why is the index not replaced?

This is quite a common thing. The code itself is stored and executed as-is, but the variable i that it references is the same one each time - and it changes.

The usual solution for this is to use forEach to iterate over the array - it means that a new function is called for each menu item. That function will then have an argument i which is different for each call.

tempArray.forEach(function(m, i) {
      if (m.finished == false)
        menuObjekt[m.machine] = function(){showSettings(m)};
      }
});

Hope that helps!
