data数据----------------

 // 最后要提交到的处方及详情
      submitCareOrder: {
        careOrder: {
          allAmount: 0.00,
          patientId: undefined,
          patientName: undefined,
          coType: '0' // 默认为药用处方
        },
        careOrderItems: []
      },

方法-----------------
赋值给careOrderItems大概为[

             {
            itemName:'分洛1',              
             num：1,
              price:5,
               amount:'50',
                remerk:'不能出',
              },{
            itemName:'分洛1',              
             num：1,
              price:5,
               amount:'50',
                remerk:'不能出',

}
