How can I access functions wrapped in $ (document) .ready (function () {}) iframe?

Question

So, I have an iframe that has some functions wrapped in $ (document) .ready (function () {}), like this.

<script>
    $(document).ready(function(){
        function foo(){
            // do some stuff
        }
    });
</script>

I know that I can access the DOM with something like $ ('iframe'). contents (). find ('something'), but can I access the foo () function from above?

iframe:

1) foo global.

$(document).ready(function(){
    foo = function(){
        //this alternate syntax declares a global function foo
        //it is very evil so be sure you really need this
        ...
    };
})

foo ,

...

function foo(){
    ...
};

$(document).ready(function(){

})

$(document).ready(function(){
    function foo(){
        //this alternate syntax declares a global function foo
        //it is very evil so be sure you really need this
        ...
    };

    function_that_uses_foo();
})

function_that_uses_foo(){
    foo(); //foo is not on cope, this doesnt work!
}

$(document).ready(function(){
    function foo(){
        //this alternate syntax declares a global function foo
        //it is very evil so be sure you really need this
        ...
    };

    function_that_uses_foo(foo);
})
