How to use the dropbox-js pullChanges method to get a file list of existing files

问题

I am using dropbox-js to access a user's dropbox files. Please note that I am very new to this...

What I need to do, is to access existing files using dropbox-js. As I understand it, the pullChanges method should be used for this. This is how I currently have it:

client.pullChanges(null, function(error, results) {
    if (error) {
        return showError(error);
    }

    alert("Dropbox contains: " + results.shouldPullAgain); //just to test that something happens
});

I'm not sure if this is the correct way to make use of pullChanges, and then I need to know how to use results to actually get the file/folder information??
