$ (document). already called inside an external function?

Question

I saw somewhere some jquery code on the net that took this form:

<script>            
function doSomething(message)
{   
    $(document).ready(function(){       
        alert(message);
        });
};
</script>

i.e. an external function ("doSomething") that has $ (document) .ready inside it. I got confused because this is not the code under $ (document) .ready called when loading the DOM? This is similar to an event handler inside a function (?). Does this form of code make sense to everyone? Thank.

        });
    }
    doSomething();
</script>

Put this in different parts of your HTML and check it (:
