一，如下代码，赋值

@{
    string json = "";       foreach (var dic in EnumCouponDic) //EnumCouponDic是一个字典类型Dictionary
     
             {       string value = dic.Value.ToString();       json = json + "{id: '" + dic.Value.ToString() + "',text: '" + dic.Key.ToString() + "'},";      }    }
      
     

二，默认选中

$('#CouponType').combobox('setValues', '2');
