how to make visible this var (rec_count) out of ajax scope? I can't understand this about ajax scope. thanks!

function showImage(str){        
    $.ajax({                                 
        url:            'getimg.php',
        type:       "GET",
        data:           "q="+str,
        dataType:   'json',
        success:    function(data){
            rec_count = data.count;
            console.log('inside: ' + rec_count)
        }
    });
}

$( document ).ready(function(){
    $('body').click(function(){
        showImage(4);
        console.log('outside: ' + rec_count)
    });
});

AJAX is async by default... – A. Wolff Oct 13 '14 at 15:15

`rec_count` is a global. Your problems have nothing to do with scope. – Quentin Oct 13 '14 at 15:15

@Quentin: No, and it's probably for the best. Most days I'd be plastered before noon. – Oct 13 '14 at 15:17
Addtl info that deals specifically with the illusion of it being a scope issue: [Why is my variable unaltered after I modify it inside of a function?](http://stackoverflow.com/questions/23667086/why-is-my-variable-unaltered-after-i-modify-it-inside-of-a-function-asynchron) – Oct 13 '14 at 15:20
