Question

我正在使用json函数插入主数据和明细数据。当我单击保存按钮然后在文本框中插入所有数据后错误显示“ 500”，并且json返回格式有效我已经检查了json 格式验证网站。现在，我正在分享json结果，您可以看到。

<span class="aaa">aaa</span>
<span class="aaa">aaa</span>
<span class="aaa">aaa</span>
<span class="aaa">aaa</span>
<span class="aaa">aaa</span>
<span class="aaa">aaa</span>
<div id = "ex"></div>

我正在分享一切意味着控制器代码，HTML，JavaScript 功能有人告诉我我哪里错了，我的问题是什么代码。

控制器

{"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"}

Answer 1

JSON数据所有属性的

类型必须与您向其发送数据的INNER函数的参数类型相对应。在您的示例中，您发送JSON数据

Items_Insert

其中所有属性均为字符串。另一方面，您使用

{
    "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"
}

和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)的其他一些属性，它们也不是字符串：

Items

因此，您必须将另一个格式的数据发送到服务器，或将某些参数和属性的类型从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; }的{{1}}更改为字符串。

我提醒您，数字的JSON序列化是不加引号，例如int而不是float。

要在客户端解决此问题，您需要像这样发送数据

因此，您需要在JavaScript代码的某些位置添加"1"和{ "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" }。例如，您应该使用

parseInt

代替

parseFloat

用于当前代码。您必须对所有属性进行仔细更改，在服务器代码中将其解释为整数而不是字符串的浮点数。
