jqGrid 未在 MVC 中显示 json 数据
jqGrid not showing json data in MVC
jqGrid 没有显示从 MVC 控制器获取的 json 数据,它还有一个 emptyrecords 标签,在这种情况下也不可见。这是我的 jQuery 代码-
$(function () {
$("#JQGrid1").jqGrid({
url: "/CertificateDetails/GetCertificateDetails",
datatype: 'json',
mtype: 'Get',
colNames: ['Name', 'Issuer', 'Location', 'Private Key[Yes/No]'],
//data: dataArray,
colModel: [
{
key: false,
name: 'Name',
index: 'Name',
editable: false
},
{
key: false,
name: 'Issuer',
index: 'Issuer',
editable: false
},
{
key: false,
name: 'Location',
index: 'Location',
editable: false
},
{
key: false,
name: 'HasPrivateKey',
index: 'HasPrivateKey',
editable: false
}
],
height: '100%',
viewrecords: true,
caption: "Certificate Details",
emptyrecords: "No record to display!!"
});
});
控制器代码:
CertDetails cd = new CertDetails();
public ActionResult Index()
{
return View();
}
//
// GET: /CertificateDetails/
public ActionResult GetCertificateDetails()
{
var stores = new Dictionary<StoreName, string>()
{
{StoreName.My, "Personal"},
{StoreName.Root, "Trusted roots"},
{StoreName.TrustedPublisher, "Trusted publishers"},
{StoreName.AddressBook, "Address Book"},
{StoreName.AuthRoot, "Auth Root"},
{StoreName.CertificateAuthority, "Certificate authority"},
{StoreName.Disallowed, "Disallowed"},
{StoreName.TrustedPeople, "Trusted people"}
// and so on
}.Select(s => new { store = new X509Store(s.Key, StoreLocation.LocalMachine), location = s.Value }).ToArray();
foreach (var store in stores)
store.store.Open(OpenFlags.ReadOnly); // open each store
var list = stores.SelectMany(s => s.store.Certificates.Cast<X509Certificate2>()
.Select(mCert => new CertDetails
{
HasPrivateKey = mCert.HasPrivateKey ? "Yes" : "No",
Name = mCert.FriendlyName != "" ? mCert.FriendlyName : "Unavailable",
Location = s.location,
Issuer = mCert.Issuer
})).ToList();
return Json(list,JsonRequestBehavior.AllowGet);
}
这里是controller action方法返回的数据-
[{"Name":"Unavailable","HasPrivateKey":"Yes","Location":"Personal","Issuer":"CN=Dell Issuing Certificate Authority 302, OU=MS PKI, O=Dell Inc."},{"Name":"IIS Express Development Certificate","HasPrivateKey":"Yes","Location":"Personal","Issuer":"CN=localhost"}]
我正在从控制器获取 JSON 格式的数据,但 jqGrid 既不显示任何数据也不显示空记录标签。知道如何解决这个问题吗?
您可以试试 jQuery DataTable 插件,如下所示:
$(document).ready(function () {
$("#myGrid").dataTable({
"ajax": {
"url": "/CertificateDetails/GetCertificateDetails",
"dataSrc": ""
},
"columns": [{
"data": "Name"
}, {
"data": "Location"
}, {
"data": "Issuer"
}, {
"data": "HasPrivateKey"
}]
});
});
<table id="myGrid">
<thead>
<tr style="text-align:left;">
<th>Name</th>
<th>Location</th>
<th>Issuer</th>
<th>HasPrivateKey?</th>
</tr>
</thead>
</table>
