Facebook工作历史fql

我正在创建facebook应用程序,用户将能够获取朋友列表中所有朋友的公司名称

FB.api('/me', function(response) { 
    var query = FB.Data.query('select name,work,work_history,pic_square 
       from user where uid IN (SELECT uid2 FROM friend WHERE uid1={0})', response.id) 
    query.wait(function(rows){ 
      var data = ""; 
      for (var i = 0; i < rows.length;i++) { 
         data += rows[i].name + " => " +'<img src="' +rows[i].pic_square + '" alt="image" />' + "===> "; 
         if(rows[i].work[i]||rows[i].work_history[i]) { 
             data+=rows[i].work_history[0].company_name+ "<br/>"; 
         } 
         data += "<br />";
       } 
       document.getElementById('location').innerHTML = data; 
     }); 
   }); 
}
