Take a look at the .get() documentation. You're using it incorrectly.

You should be passing data (optional) and handling the data that gets returned, at a minimum:

$.get("backend.php",
    {
        // data passed to backend.php goes here in 
        //
        // name: value
        //
        // format. OR you can leave it blank.
    }, function(data) {
        // data is the return value of backend.php
        // process data here
    }
);

If you pass data, you can retrieve it on backend.php using $_GET. In this case:

$_GET['name'];
