验证blazor后链接到不同页面

Question

嗨，我想问有没有一种方法可以提交验证并链接到BLAZOR中的其他页面这就是我将取消链接到其他页面的方式

<NavLink href="@($"/personal/list/1")">
<button class="btn btn-primary" @onclick="CloseModal">@Loc["cancel"]</button>
</NavLink>

那是我的子限制按钮

<button type="submit" class="btn btn-success">@Loc["save"]</button>

这是内部按钮的编辑模型

<EditForm Model="PersModel" OnValidSubmit="@CreatePersonal">
<FluentValidator TValidator="PersonalViewModelValidator" />

这是有效子传输到API 的连接

protected async Task CreatePersonal()
{
var token = Storage["JWT-Token"];
bool personalExist = false;
Http.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
//Convert Selected values into the Pers database values
PersModel.Pers.Group = PersModel.SelectedGruppe?.Name;
PersModel.Pers.Anrede = PersModel.SelectedAnredeName;
PersModel.Pers.Grad = PersModel.SelectedGradName;
PersModel.Pers.Titel = PersModel.SelectedTitelName;
PersModel.Pers.Department = PersModel.SelectedAbteilungName;
PersModel.Pers.Group = PersModel.SelectedGruppeName;
PersModel.Pers.PrevDepartment = PersModel.SelectedPrevAbteilungName;
PersModel.Pers.PrevGroup = PersModel.SelectedPrevGruppeName;
PersModel.Pers.Uni = PersModel.SelectedStaetteName;
//on input select after editing the --Select-- is converted into value

try
{
BoolValue uh = await Http.GetFromJsonAsync<BoolValue>(Storage["environment_uri"] + "/personal/exists/" + PersModel.Pers.PersName);
personalExist = uh.Value;
}
catch (Exception ex)
{
Logger.LogWarning(ex, "Failed to load  BoolValue uh");
Storage.SetItem("Transaction", "errorload");
}

if (personalExist == false && PersModel.Pers.PersName != "_add_")
{
await Http.PostAsJsonAsync(Storage.GetItem("environment_uri") + "/personal", PersModel.Pers); // thats the one i add here
Storage.SetItem("Transaction", "modified");
await OnParametersSetAsync();
CloseModal();
}
else if (isEdit == true)
{
// here was post in original
await Http.PutAsJsonAsync(Storage.GetItem("environment_uri") + "/personal", PersModel.Pers); // this update
CloseModal();
Storage.SetItem("Transaction", "modified");
await OnParametersSetAsync();
}
else if (isEdit == false && personalExist == true)
{
Storage.SetItem("Transaction", "errorsame");
await OnParametersSetAsync();
}

}

这就是验证类

public PersonalViewModelValidator()
{
CascadeMode = CascadeMode.StopOnFirstFailure;
RuleFor(data => data.Pers.PersName).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.Bezeichnung).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.Id).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.Street).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.HouseNumber).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.PLZ).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.Location).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.DateHired).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.FullTime).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.Pers.Email).EmailAddress().WithMessage("A valid email address is required.");
//rule for the sieze max
RuleFor(data => data.Pers.Comment_1).Length(0,40).WithMessage("Must be less than 40 characters");
RuleFor(data => data.Pers.Comment_2).Length(0,40).WithMessage("Must be less than 40 characters");
// not working
RuleFor(data => data.SelectedAbteilungName).NotEmpty().WithMessage("is a required field.");
RuleFor(data => data.SelectedGruppeName).NotNull().WithMessage("is a required field.");
//RuleFor(data => data.SelectedAbteilung).NotEmpty().WithMessage("Abteilung  is a required field.");
//RuleFor(data => data.SelectedGruppe).NotNull().WithMessage("Test test");
}

那么，如果有验证错误等链接到另一个页面并从Toster(例如(获得消息，那么提交所有这些信息是什么

NavLink href="@($"/personal/list/1")

@if (Storage.GetItem("Transaction") == "modified")

｛

Toaster.Success(@TLoc["success1"], @TLoc["success2"]);
Storage.RemoveItem("Transaction");

}

我找到了的解决方案

[Inject]
public NavigationManager NavigationManager { get; set; }
protected void NavigateToOverview()
{
NavigationManager.NavigateTo("/personal/list/1");
}

然后你只需要在API 的结果之后调用这个方法

NavigateToOverview();

在我的情况下是

else if (isEdit == true)
{
// here was post in original
await Http.PutAsJsonAsync(Storage.GetItem("environment_uri") + "/personal", PersModel.Pers); // this update
CloseModal();
Storage.SetItem("Transaction", "modified");
await OnParametersSetAsync();
NavigateToOverview();
}
