遺漏的類型錯誤：無法讀取的不確定

Question

財產「的companyName」我試圖解決這個錯誤，但我堅持和需要幫助解決這個，因爲我是新來angularjs：

TypeError: Cannot read property 'companyName' of undefined 
    at Scope.$scope.companyModify (app.js:8501) 
    at $parseFunctionCall (base.js:21610) 
    at callback (base.js:30772) 
    at Scope.$eval (base.js:23672) 
    at Scope.$apply (base.js:23771) 
    at HTMLButtonElement.<anonymous> (base.js:30777) 
    at HTMLButtonElement.dispatch (base.js:4430) 
    at HTMLButtonElement.elemData.handle (base.js:4116) 

---

$scope.companyModify = function(company) { 
    var param = { 
     companyName: $scope.companyName, 
     billColumn: $scope.billColumn, 
     billTitle: $scope.billTitle, 
     serviceTax = $scope.serviceTax, 
     wishMessage = $scope.wishMessage, 
     billTypeId = $scope.billTypeId 
    }; 

    SocketService.post(apiManage.apiList['CompanyModify'].api, param).then(function(resp) { 
     var data = resp.data.response; 

     if (data.status === true) { 
      angular.forEach($scope.companyList, function(value) { 
       if (value.billTypeId == billTypeId) { 
        value.$edit = false; 
       } 
      }); 

      Notify.alert(data.message, { 
       status: 'success', 
       pos: 'top-right', 
       timeout: 5000 
      }); 
      $scope.load(); 

     } else { 
      Notify.alert(data.message, { 
       status: 'danger', 
       pos: 'top-right', 
       timeout: 5000 
      }); 
     } 
    }); 
};

我認爲你的對象'param'是錯誤構造的。

能不能請你 -

var param = { 
    companyName: $scope.companyName, 
    billColumn: $scope.billColumn, 
    billTitle: $scope.billTitle, 
    serviceTax: $scope.serviceTax, 
    wishMessage: $scope.wishMessage, 
    billTypeId: $scope.billTypeId 
}; 

有 '='，這應改爲標誌 '：'

其次，請確保所有的變量，公司名稱，billColumn ..等都是附加到模型，即$範圍之前，您調用該方法 - $ scope.companyModify（）

讓我知道這是否有幫助。
