Make variable global

[unemployment]

How can I make my alert work?  Right now it is undefined and I need to make my function in the variable global.  Can this be done?

 

if (json_goals === undefined)
{
ajax.get('/assets/ajax/user_goals.php', function (resp)
{
	var json_goals = resp;

	return json_goals;
});
}
alert(json_goals);

You cannot assume that the AJAX happens immediately. When you call .get the process will start but you can't know when it will complete. Meanwhile the rest of your code continues executing.

 

If you need stuff to happen when the AJAX completes then put the code inside the callback function.

I understand what you mean by completing, but I don't have a clue on what you mean when you say call back function.  Please explain

That function in the code you posted? Without a name? That's a callback because your code will be "called back" when something happens (in this case, that function executes when the AJAX completes).
