If you are trying to access the gadget id from JavaScript in the gadget itself, you can use __MODULE_ID__. This is automatically replaced by the iGoogle server with the actual module ID and is used in a number of standard libraries as a general constructor parameter (see the Gadgets API Reference ).

If you are using the new gadget API (part of the OpenSocial specification and is currently only available on iGoogle in iGoogle Sandbox), then you have another option:gadgets.Prefs.getModuleId()
