Self-references in object literal declarations

Hey Guys,

i have a small question regarding JavaScript Objects.
I have the following Object in JavaScript:

var CONFIG = {
    MAIN_URL: 'http://www.test.us',
    MAIN_COLOR: '#fff'
}

now i want to declare an object with another object prefixed:

var CONFIG = {
    MAIN_URL: 'http://www.test.us',
    LOGIN_URL: MAIN_URL+'/login', // <- this one!
    MAIN_COLOR: '#fff'
}

how do i do that?
I have tried with this.MAIN_URL, CONFIG[MAIN_URL], CONFIG.MAIN_URL – but nothing works?!?!

Thanks,
Sascha

You can’t do that in an object initializer. Instead, do something like this:

var CONFIG = {};
CONFIG.MAIN_URL = 'http://www.test.us';
CONFIG.LOGIN_URL = CONFIG.MAIN_URL+'/login'; // <- this one!
CONFIG.MAIN_COLOR = '#fff';
