Query Strings

We can pass along query strings to our pages by placing them in our links:

l('Pizza', 'pizza?foo=bar');

Then when we click the Pizza link and go to the pizza page, we can access the value of foo anywhere in our code:

drupalgap_alert(_GET('foo'));

Which would then alert the user to bar.

This is a very powerful feature for dynamically sending/receiving data as you navigate around the app between pages.
