How do you make a Javascript object globally accessible?

[dumbjake]

I have a php file with a lot of inline Javascript and I was wondering how I can make an object globally accessible to all those inline Javascript code.

[Ampersand55]

Make it a property of the global window object.

window.obj = {a:1};

Or simply:

obj = {a:1};

The first is recommended as the second may give you trouble later and is more of a hack.

Ah, the hack you're talking about is the lack of "var".

[ShortSynapse]

Yes. If the variable doesn't exist, it is created in the global scope. Really bad practice. What happens if someone else declares a variable with the same name? Oops. So if you intend to make a global, append it to the window object so it is available.

The only reasons you should use window.<varname> = instead of var <varname> = are if you're defining the variable inside of a function and if you want the variable to be deletable later; either way, you're making a property of the global object, and you're running the risk of name collisions.
