这是控制器代码,但这不应该太重要:
[HttpPost]
public ActionResult AccountCreated(Models.AccountViewModel model)
{
String Account_Name = model.Account_Name;
String Account_Password = model.Password;
if (!ModelState.IsValid)
{
return RedirectToAction("CreateAccount");
}
//if (Account_Name == null || Account_Password == null)
// return RedirectToAction("CreateAccount");
WebForumEntities2 db = new WebForumEntities2();
foreach(Account eachAccount in db.Accounts)
{
if (eachAccount.Account_Name.Equals(Account_Name))
{
return RedirectToAction("AccountCreatedMessage");
}
}
int nextiD = 0;
if (db.Accounts.ToList().Count > 0)
{
nextiD = db.Accounts.ToList().Last().Id + 1;
}
var newAccount = new Account();
newAccount.Account_Name = Account_Name;
newAccount.Password = Account_Password;
newAccount.Id = nextiD;
db.Accounts.Add(newAccount);
db.SaveChanges();
return RedirectToAction("CreateAccount");
}

- 我尝试过调试,但从未调用javascript函数
public class AccountViewModel
{
[Required] // data attribute
public string Account_Name;
[Required]
public string Password;
}
然后,您可以正常提交表格。如果ASP.NET引擎检测到任何数据验证错误,它会将类。字段验证错误
放在您的输入上
您可以根据自己的喜好设置此类的样式,如下所示:
.field-validation-error
{
border-color: red;
}
其他一些注意事项:
- 如果有一个表单嵌套在另一个表单中,我将删除该表单 在你的按钮周围
- 不知道为什么要将输入放入字符串中 在控制器中,而不是使用ViewModel李>
- 我通常将DbContext放在ActionResults之外,请确保将其处理掉
