我试图将json对象传回我的设备控制器中的动作，然后将其插入到数据库中，但是当我单击表单上的提交按钮时，它似乎会触发两次。另一个问题是我在json对象和pfID中的位置字段没有被发送回控制器，其他字段被正确发回。这是我的代码：
$('#getDevice').unbind('click').bind('click', function (e) {
e.stopPropagation();
//anti forgery token
//get the form
var form = $('#addDeviceForm');
//from the form get the antiforgerytoken
var token = $('input[name="__RequestVerificationToken"]', form).val();
var URL = 'Devices/PushIPForCollection';
//Before this we need to build the model from the input the user has given us
var device = {
deviceID: ' ',
ipAddress: $('#dIPAddress').val(),
deviceName: $('#dDeviceName').val(),
CreatedDate: ' ',
UpdatedDate: ' ',
CreatedBy: ' ',
UpdatedBy: ' ',
deviceSubGroupID: $('#dSubgroup option:selected').val(),
subgroup: " ",
companyID: ' ',
hidden: ' ',
pfID: $('#dpfID option:selected').val(),
pf: ' ',
location: JSON.stringify({
'region': $('#dRegion').val() == null ? ' ' : $('#dRegion').val(),
'country': $('#dCountry').val() == null ? ' ' : $('#dCountry').val(),
'city': $('#dCity').val() == null ? ' ' : $('#dCity').val(),
'building': $('#dBuilding').val() == null ? ' ' : $('#dBuilding').val(),
'room': $('#dRoom').val() == null ? ' ' : $('#dRoom').val(),
'rack': $('#dRack').val() == null ? ' ' : $('#dRack').val()
})
};
alert(device.pfID);
alert(device.location);
$.ajax({
url: URL,
data: {
__RequestVerificationToken: token,
device: device
},
type: 'POST',
success: function (result) {
},
error: function (jqXHR, textStatus, errorThrown) {
alert("An error has occurred please contact us");
}
})
$('#add-device').modal('hide');
return false;
});
在我提醒我的pfID的地方，它返回一个"ba4475ef-0eed-441a-a77e-d733c288bf8e"
这是我的模特：
public class Devices
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int deviceID { get; set; }
[Display(Name="IP Address:"), StringLength(50)]
public string ipAddress { get; set; }
[Display(Name = "DeviceName:"), StringLength(50)]
public string deviceName { get; set; }
public DateTime? CreatedDate { get; set; }
public DateTime? UpdatedDate { get; set; }
public string CreatedBy { get; set; }
public string UpdatedBy { get; set; }
[Display(Name="Add to subgroup:")]
public long? deviceSubGroupID { get; set; }
[ForeignKey("deviceSubGroupID")]
public DeviceSubGroup subgroup { get; set; }
public string companyID { get; set; }
public string hidden { get; set; }
public string pfID { get; set; }
[ForeignKey("pfID")]
public PfHealth.Pf pf { get; set; }
public string location { get; set; }
}
这是我的帖子方法：
public ActionResult PushIPForCollection(Devices device)
{
//Before committing to the database we need to check if the device already exists
var checkIfDeviceExists = db.devices.Any(check => check.ipAddress == device.ipAddress);
if (!checkIfDeviceExists)
{
if (ModelState.IsValid)
{
var userID = User.Identity.GetUserId();
device.CreatedDate = DateTime.Now;
device.UpdatedDate = DateTime.Now;
device.CreatedBy = userID;
device.UpdatedBy = userID;
var subgroup = db.deviceSubGroups.Where(sub => sub.deviceSubID == device.deviceSubGroupID).FirstOrDefault();
device.communityString = subgroup.snmpCommunityString;
device.companyID = subgroup.companyID;
db.devices.Add(device);
db.SaveChanges();
}
}
//Can change this to get json in order to let to view know what message to display to the user.
return RedirectToAction("index");
}
