What you have coded doesn't work because the $.get call is *asynchronous*.
When you call $.get, $.post, $.ajax or any async function you pass a
callback function. The actual $.get call returns immediately, but the
results from the server aren't passed to your callback method until the
server responds. That may take a few hundred milliseconds or it may be many
seconds. You have no control over when the response is received so you need
to structure your code with that in mind.
