初学者的困境。在萤火虫中显示移动和国家代码值的错误。我的脚本文件
$(function () {
$('#edit-form').submit(function () {
member = {

Mobile: $('#mob-name').val(),
Languages: $('#Language').val(),
Email: $('#email-name').val()
};
if ($('#edit-form input').length = 0) { $('#message').html('<strong>Error : </strong><span style="color: #e2442b;">Please fill the required fields</span>'); return; }
else { $('#message').html('<strong>Processing : </strong><span>Saving information. Please wait...</span>'); }
$('#edit-form .wrap').children('*:not(label)').attr('disabled', true);
$.ajax({

if(d.s){
$('#message').html('<strong>Success : </strong><span class="success_msg">Your information saved</span>');
setTimeout(function () { $('#message').children().fadeOut(); }, 5000);
}
else {

}
$('#data .ip_wrap').children('*:not(label)').attr('disabled', false);

$('#edit-form .wrap').children('*:not(label)').attr('disabled', false);
}
});
});
$('#cancel').click(function () { if (document.referrer != '') { history.back(); } else { location.href = "/Account/Index"; } });
});

和我的控制器，我不确定这是否正确！
public JsonResult Edit(string FirstName, string Middlename, string LastName, short CountryCode, int Mobile, Language Languages, string Email)
{
Models.User users = new User { FirstName = FirstName, Middlename = Middlename, LastName = LastName, CountryCode = CountryCode, Mobile = Mobile, Language = Languages,Email =Email };
if (users.Save())
{
return Json(new { s = users.Status == UserStatus.Active, m = "Not changed", id = users.UserID });
}
else return Json(new {s = false, m = "You don't have enough permission to edit this profile" });
}
和我的保存方法
public bool Save() {
bool updated = false;
DatabaseCommaned cmd = new DatabaseCommaned();
cmd.CommandText = "UPDATE tUser SET";
if (_firstName != FirstName) {
cmd.CommandText += " FNAID = @fnaid,";
cmd.Parameters.AddWithValue("@fnaid", string.IsNullOrEmpty(FirstName) ? DBNull.Value : (object)Names.GetName(FirstName).NameID);
updated = true;
}
if (_middleName != Middlename) {
cmd.CommandText += " MNAID = @mnaid,";
cmd.Parameters.AddWithValue("@mnaid", string.IsNullOrEmpty(Middlename) ? DBNull.Value : (object)Names.GetName(Middlename).NameID);
updated = true;
}
if (_lastName != LastName) {
cmd.CommandText += " LNAID = @lnaid,";
cmd.Parameters.AddWithValue("@lnaid", string.IsNullOrEmpty(LastName) ? DBNull.Value : (object)Names.GetName(LastName).NameID);
updated = true;
}
if (_email != Email) {
cmd.CommandText += " Email = @email,";
cmd.Parameters.AddWithValue("@email", Email);
updated = true;
}
if (_countryCode != CountryCode) {
cmd.CommandText += "MobCountryCode = @ccode, ";
cmd.Parameters.AddWithValue("@ccode", CountryCode);
updated = true;
}
if (_mobile != Mobile) {
cmd.CommandText += " Mobile = @mob,";
cmd.Parameters.AddWithValue("@mob", Mobile);
updated = true;
}
if (_status != Status) {
cmd.CommandText += " ST = @st,";
cmd.Parameters.AddWithValue("@st", Status);
updated = true;
}
if (_language != Language) {
cmd.CommandText += " LN = @ln,";
cmd.Parameters.AddWithValue("@ln", Language);
updated = true;
}
if (_expiry != Expiry) {
cmd.CommandText += " ExpDT = @exp,";
cmd.Parameters.AddWithValue("@exp", Expiry);
updated = true;
}
if (updated == true) {
cmd.CommandText = cmd.CommandText.TrimEnd(',');
cmd.CommandText += " WHERE UID = @uid";
cmd.Parameters.AddWithValue("@uid", _userID);
updated = cmd.ExecuteNonQuery() == 1;
if (updated) {
copyPropertiesInternally();
Logs.LogEvent(LogEvent.UserUpdated, _userNA);
}
}
return updated;
}
FireBug 中的错误
