Accessing dynamically loaded variables

[dnn]

How can I access dynamically loaded variables?

I am trying to load an external javascript file dynamically and then
access its variables. The script is loaded by the onload handler.

The code looks like this:
var constants = document.createElement("script");
constants.src = REL_PATH + "extensions_demo/js/constants_" +
MY_LANGUAGE + ".js";
constants.type ="text/javascript";
document.getElementsByTagName("head")[0].appendChild(constants);
alert(window.ROOM_01); // ROOM_01 is a variable out of the external
file

However alert(window.ROOM_01) returns 'undefined'. How can the
variables of the dynamically loaded file be accessed?

Thanx for helping.

Cheers,
Nico

Either by ROOM_01 or window.ROOM_01 or window['ROOM_01']

If it is alerting undefined then something is wrong in your src path.
Or, ROOM_01 is not a global variable.

Try alerting constants.src and make sure it is what you wanted it to be
and that it is a valid path.

Put an alert in the external file to make sure it is getting loaded.
