javascript - JSON object null in browser but not firebug -

-

when step through javascript code (scoreboard.js) in firebug, works fine alerts. when don't put line break in firebug , run normally, received "favs null" message (no alerts).

var favs = $.getjson("favs.json"); favs = $.parsejson(favs.responsetext); favs = favs.myteams;  (i=0; i<favs.length; i++){     alert(favs[i].text); }

the json (favs.json)

{"myteams":[{"sport":10,"id":10,"abbrev":"nyy","isfav":false,"text":"new york  yankees","sw_abbrev":"nyy"},{"sport":28,"id":19,"abbrev":"nyg","isfav":false,"text":"new york giants","sw_abbrev":"nyg"},{"sport":46,"id":18,"abbrev":"ny","isfav":false,"text":"new york knicks","sw_abbrev":"nyk"},{"sport":90,"id":11,"abbrev":"nj","isfav":false,"text":"new jersey devils","sw_abbrev":"njd"},{"sport":41,"id":2507,"abbrev":"prov","isfav":false,"text":"providence friars"},{"sport":46,"id":17,"abbrev":"nj","isfav":false,"text":"new jersey nets","sw_abbrev":"njn"},{"sport":600,"id":363,"abbrev":"blues","isfav":false,"text":"chelsea","sw_abbrev":"eng.chelsea","isnational":false}]}

the html

<html> <head>     <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>     <script type="text/javascript" src="scoreboard.js"></script>         </head>  <body>     test </body>

any idea going on here?

you don't need 

favs = $.parsejson(favs.responsetext);

and i'm pretty sure $.getjson() doesn't return json, returns jqxhr.

looking @ documentation parsejson(), should doing:

jquery.getjson( url [, data] [, success(data, textstatus, jqxhr)] )

$.getjson("favs.json",           function(json) {   var favs = json.myteams;      (i=0; i<favs.length; i++){       alert(favs[i].text);     }   });

$.getjson() - success callback (in example anonymous function) passed returned data, typically javascript object or array defined json structure , parsed using $.parsejson() method.
