Parse.com: user is not defined

Question

I'm using parse.com as a back end for a web app. I have a user that I have signed in to the app, and when the user is signed in to the website, I want their name to appear on every page in the website.

Here is my code for trying to recognize the username of the user:

// user logs on and is redirected to this page
var user = Parse.User.current();
user.on('change', function () {
console.log(user.get("username"));
});
user.fetch();

However, when I check the console, the error

Uncaught ReferenceError: user is not defined

is present.

In my research, I've modified the code from Unable to get User's data . However, in my case, this code is not working.

Any help is greatly appreciated!

Try this:

var user = Parse.User.current();
user.fetch().then(function(fetchedUser){
    var name = fetchedUser.getUsername();
}, function(error){
    //Handle the error
});
