jquery - Pushing a variable outside of a function -

i have jquery code block twitter widget i'm developing ,

$.getjson("http://twitter.com/users/show.json?screen_name=" + twitterfeed + "&callback=?" ,     function(data) {          var fstring = ($('<div id="userimage"><h1>'+ data.followers_count +'</h1></div>').digits()).text();     var tstring = ($('<div id="userimage"><h1>'+ data.statuses_count +'</h1></div>').digits()).text();            $('#left-sidebar').prepend('<div id="userimage"><h1>'+ tstring +'</h1></div>');         $('#left-sidebar').prepend('<div id="userimage"><h2>tweets</h2></div>');                 $('#left-sidebar').prepend('<div id="userimage"><h1>'+ fstring +'</h1></div>');         $('#left-sidebar').prepend('<div id="userimage"><h2>followers</h2></div>');         $('#left-sidebar').prepend('<div id="userimage"><img id="profileimagelarge" src=' + data.profile_image_url + '></div>');     }); 

i want grab fstring , tstring , use them in outside functions.

i need value of data.followers_count , data.statuses_count passed along variable value correct in function instead of undefined.

you don't need put them in global context using window.fstring, can move var declarations outside of $.getjson.

in javascript closures allow access variables defined outside function, vars defined in function not accessible outside.

var fstring, tstring;  $.getjson(... , function(){   fstring = ...; }); 

any functions defined in same scope s $.getjson have access fstring , tstring
