【问题描述】:
我正在尝试使用 MySql 项目将数据表实现到我的 MVC ASP.NET Core,因此我按照分步教程进行操作,但我无法修复此错误:
“DataTables 警告:表 id=tblCustomers - 请求第 0 行第 0 列的未知参数“CustomerID”。有关此错误的详细信息,请参阅http://datatables.net/tn/4"
这是我的 HTML 视图页面:
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<style type="text/css">
body {
font-family: Arial;
font-size: 10pt;
}
</style>
</head>
<body>
<div style="width: 500px">
<table id="tblCustomers" cellpadding="0" cellspacing="0" border="1" style="border-collapse:collapse">
<thead>
<tr>
<th>Customer Id</th>
<th>Name</th>
<th>City</th>
<th>Country</th>
</tr>
</thead>
<tbody></tbody>
</table>
</div>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.min.js"></script>
<link href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(function () {
$.ajax({
type: "POST",
url: "/Home/AjaxMethod",
data: '{}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function (response) {
alert(response.d);
},
error: function (response) {
alert(response.d);
}
});
});
function OnSuccess(response) {
$("#tblCustomers").DataTable(
{
bLengthChange: true,
lengthMenu: [[5, 10, -1], [5, 10, "All"]],
bFilter: true,
bSort: true,
bPaginate: true,
data: response,
columns: [{ 'data': 'CustomerID' },
{ 'data': 'ContactName' },
{ 'data': 'City' },
{ 'data': 'Country' }]
});
};
</script>
</body>
</html>
这是我的控制器:
public class HomeController : Controller
{
private DBCtx Context { get; }
public HomeController(DBCtx _context)
{
this.Context = _context;
}
public IActionResult Index()
{
return View();
}
[HttpPost]
public IActionResult AjaxMethod()
{
var customers = Context.Customers.ToList();
return Json(JsonConvert.SerializeObject(customers));
}
}
我的 AjaxMethod 正在返回:
Newtonsoft.Json.JsonConvert.SerializeObject 返回 "[{"CustomerID":1,"ContactName":"Lucas","City":"Jundiai","Country":"Brasil"},{"CustomerID": 2,"ContactName":"Vitoria","City":"Jundiai","Country":"Brasil"},{"CustomerID":3,"ContactName":"Soutto","City":"Jundiai", "国家":"巴西"}]" 字符串
