Question

It’s like this:

<script>
  var global_var = {foo:1};
</script>

<script src="myscript.js"></script>

in myscript.js I have

jQuery(document).ready(function($){    
  var global_var = typeof global_var == 'undefined' ? {foo:2} : global_var;
  console.log(global_var);    
});

But the global_var does not seem to be recognized in my 2nd script, even though I clearly defined it in the first, like a global variable.

The problem is the “var” in “var global_var” within your jQuery function. This is creating a different “global_var” variable within your function instead of using the true global. Drop this and your code works as expected.
