EXT JS store не правильно загружает данные с вызова getJson

Question

Я делаю сетку EXTJS4. Мне нужно изменить некоторую информацию из моего объекта JSON, а затем вернуть его в store11, чтобы он мог загрузиться в мою сетку EXTJS. Моя проблема ниже моей функции employeeData. Я получаю нулевые значения. Похоже, что getJson вызывается после моей функции. Если я предупреждаю элементы (см. Ниже), я получаю значения там, поэтому я знаю, что он работает. Я просто не могу получить значения в моей сетке EXT для заполнения.

data = {"head":["exec_name","exec_id","P","R","O","M","I","S","E"], 
"data":[["Jack Black","4618",".8",".15","1.25",".99",".11",".14",".13"], 
["Jack Johnson","7020",".64",".27","2.64","2.73",".32",".09",".09"], 
["Jack Daniels","1511","2.25","1.25","5","3.5","1.25","1.25",".75"], 
["Jack Miller","4500","0",".4","1.6","1.8","0","0",".4"], 
["Mayor Quinby","9624","0","0","1","3","0","0","0"], 
["Bart Simpson","0613","1.05",".35","1.35","2.65",".35",".3",".2"], 
["Homer Simpson","8470","1",".61","5.17","3.61","1.11","0",".33"], 
["Marge Simpson","0718","1.11",".03","1.87","1.76",".45",".55",".16"], 
["Lisa Simpson","6291","3.11",".64","2.79","3.21",".57",".43",".43"], 
["Maggie Simpson","0298","4.12","1.53","3.74","5.59","2.03","1.03","1"], 
["Abu","3392",".3",".17",".57","1.53",".03",".13",".07"], 
["Mr Burns","8276","1.56",".46","2.73","2.87",".67",".23",".13"], 
["Santas Helper","1005",".37",".08",".75",".77",".12",".03",".05"]]}} 

Ext.onReady(function(){ 
employeeData = function(){ 
    $.getJSON('/eval.rpt_promise', function(data) { 
     var items = []; 
     $.each(data.data, function(key, val) { 
      theJson=[]; 
      $.each(val, function(k, v) { 
       if(k == 0){k = "exec_name";} 
       if(k == 1){k = "exec_id";} 
       if(k == 2){k = "p";} 
       if(k == 3){k = "r";} 
       if(k == 4){k = "o";} 
       if(k == 5){k = "m";} 
       if(k == 6){k = "i";} 
       if(k == 7){k = "s";} 
       if(k == 8){k = "e";} 
       theJson.push(k+":"+'"'+v+'"'); 
      }); 
      items.push("{"+theJson+"}"); 
     }); 
     alert(items); 
    }); 
    return items;    
}; 

store11 = Ext.create('Ext.data.JsonStore', { 
    fields:['exec_name', 'exec_id', 'p', 'r', 'o', 'm', 'i', 's', 'e'], 
    data: employeeData() 
}); 

store11.loadData(employeeData()); 
}); 

Когда я бдительные пункты, которые я получить

items = [{exec_name:"Jack Black",exec_id:"4618",p:".8",r:".15",o:"1.25",m:".99",i:".11",s:".14",e:".13"},

{exec_name:"Jack Miller",exec_id:"5500",p:"0",r:".4",o:"1.6",m:"1.8",i:"0",s:"0",e:".4"},

Answer 1

Почему Ext.data.JsonStore? Он должен быть Ext.data.ArrayStore.

store11 = Ext.create('Ext.data.ArrayStore', { 
    fields:['exec_name', 'exec_id', 'p', 'r', 'o', 'm', 'i', 's', 'e'], 
    data: employeeData() 
}); 

Второй выпуск (и основной) является employeeData() асинхронный запрос, и вы не можете использовать результат, вы должны переписать код, чтобы создать магазин в JSon обратного вызова.
