Question

Я вставляю основные и подробные данные, используя функцию json.после вставки всех данных в текстовое поле, когда я нажимаю кнопку «Сохранить», эта ошибка показывает «500» и возвращаемый формат json действителен. Я уже проверяю веб-сайт проверки формата json.Теперь я делюсь результатами, которые вы можете увидеть.

{"ItemCode":"001-0001","ItemDesc":"1","PackingDetail":"1","ReOrder_Lvl":"1","Curr_Qty":"1","Curr_Rate":"1","Curr_Value":"1","items":[{"Srno":"1","MUnitCode":"02","BasicUnit_Qty":"1","SaleRate":"1","TableName":"ItemMeasuring"},{"Srno":"1","God_ID":"2","Op_Qty":"1","Op_Amount":"1","TableName":"ItemOpening"}],"btnAddNew":"new"}

Я делюсь всем, что означает, код контроллера, HTML, функция javascript, кто-нибудь скажет мне, где я не прав и в чем проблема в моем коде.

Answer 1

Тип всех свойств данных JSON должен соответствовать типу параметров функции Items_Insert, в которую вы отправляете данные.В вашем примере вы отправляете данные JSON

{
    "ItemCode": "001-0001",
    "ItemDesc": "1",
    "PackingDetail": "1",
    "ReOrder_Lvl": "1",
    "Curr_Qty": "1",
    "Curr_Rate": "1",
    "Curr_Value": "1",
    "items": [{
        "Srno": "1",
        "MUnitCode": "02",
        "BasicUnit_Qty": "1",
        "SaleRate": "1",
        "TableName": "ItemMeasuring"
    }, {
        "Srno": "1",
        "God_ID": "2",
        "Op_Qty": "1",
        "Op_Amount": "1",
        "TableName": "ItemOpening"
    }],
    "btnAddNew": "new"
}

, где все свойства строки .С другой стороны вы используете

public ActionResult Items_Insert(string ItemCode, string ItemDesc, string PackingDetail,
     int ReOrder_Lvl, float Curr_Qty, float Curr_Rate, float Curr_Value,
     Items[] items,  string btnAddNew)

и некоторые другие свойства Items, которые не являются строками тоже:

public float BasicUnit_Qty { get; set; }
public float SaleRate { get; set; }
public float Op_Qty { get; set; }
public float Op_Amount { get; set; }
public int God_ID { get; set; }

Таким образом, вы должны отправить другой отформатированный данные на сервер или для изменения типа некоторых параметров и свойств с int из float на строку.

Напоминаю, что JSON-сериализация чисел * не указаны числа, такие как 1 вместо "1".

Чтобы решить проблему на стороне клиента, вам необходимо отправить данные типа

{
    "ItemCode": "001-0001",
    "ItemDesc": "1",
    "PackingDetail": "1",
    "ReOrder_Lvl": 1,
    "Curr_Qty": 1,
    "Curr_Rate": 1,
    "Curr_Value": 1,
    "items": [{
        "Srno": "1",
        "MUnitCode": "02",
        "BasicUnit_Qty": 1,
        "SaleRate": 1,
        "TableName": "ItemMeasuring"
    }, {
        "Srno": "1",
        "God_ID": 2,
        "Op_Qty": 1,
        "Op_Amount": 1,
        "TableName": "ItemOpening"
    }],
    "btnAddNew": "new"
}

Из-за этого вынужно будет добавить parseInt и parseFloat в некоторых местах вашего кода JavaScript.Например, вы должны использовать

...
God_ID: parseInt($(this).find('td:eq(1)').html(), 10),
Op_Qty: parseFloat($(this).find('td:eq(2)').html()),
...

вместо

...
God_ID: $(this).find('td:eq(1)').html(),
