Accessing Unknown Global Variables?

[admin]

Hello -

Is there a way to access global variables, whose names are not already known, including globally defined function names?

Using the for/in technique on the global window object doesn't seem to work as expected as the global x variable is never shown in this loop:

var x = "xVar";
function showGlobalProperties() {
for(var prop in window) alert("Property " +prop);
}

HOWEVER -

alert(window.x);
OR
alert(window["x"] );

works fine, as expected.

For/in seems to work fine on objects that I've created.
- unclear though why it doesn't seem to work with predefined objects. BTW, my test platform is IE6 on Win2k. Thanks for your thoughts!
