I am now in the process of removing most globals from my code by enclosing everything in a function, turning the globals into “pseudo globals,” that are all accessible from anywhere inside that function block.

(function(){

var g = 1;

var func f1 = function () { alert (g); }

var func f2= function () { f1(); }

})();

(technically this is only for my “release version”, where I append all my files together into a single file and surround them with the above….my dev version still has typically one global per js file)

This all works great except for one thing…there is one important place where I need to access some of these “globals” by string name. Previously, I could have done this:

 var name = "g";
 alert (window[name]);

and it did the same as

 alert(g);

Now — from inside the block — I would like to do the same, on my pseudo-globals. But I can’t, since they are no longer members of any parent object (“window”), even though are in scope.

Any way to access them by string?

Thanks…

    Basically no, as answered indirectly by this question: Javascript equivalent of Python's locals()?

    Your only real option would be to use eval, which is usually not a good or even safe idea, as described in this question: Why is using the JavaScript eval function a bad idea?

    If the string name of those variables really and truly is defined in a safe way (e.g. not through user-input or anything), then I would recommend just using eval. Just be sure to think really long and hard about this and whether there is not perhaps a better way to do this.
