Define global if it doesn't exist

Question

I'm trying to set a global if it doesnt exist. Total noob question.

I'm doing this:

if (!raw) { raw = 'yep'; }

But it keeps throwing reference error raw is not defined.

If you're getting a reference error then you are likely running in strict mode. — James Sumners

nope, he gets reference errors cause he doesn't "reference" raw before checking for it's value, if you wanna test for a vaiable if it exists you'd have to use "typeof raw == 'undefined'" or window.raw — Shiala

This is one way, assuming window exists:

if(!window.raw) { raw = 'yup'; }

If not, you could just make a global object to use:

globals = {}; if(!globals.raw) { globals.raw = 'yup'; }

In the global scope add:

var raw;
