所以我有一个ViewModel,并且所有属性都通过在它们上面具有必需的属性来验证。当我提交表单时,它不会抛出任何错误消息,即需要名称字段。
我想我已经找到了问题所在。它在提交按钮中,如何让按钮点击ActionList的HttpPost方法,因为此刻它没有按下它,因此模型状态没有被验证。
查看:
<h2>@ViewBag.Title</h2>
<hr>
<div class="well">
@using (Html.BeginForm("BookingDetails", "Booking"))
{
@Html.ValidationSummary(true)
<div class="form-group">
@Html.DisplayNameFor(m => m.FirstName)
@Html.TextBoxFor(m => m.FirstName, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.FirstName)
</div>
<div class="form-group">
@Html.DisplayNameFor(m => m.Surname)
@Html.TextBoxFor(m => m.Surname, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Surname)
</div>
<div class="form-group">
@Html.DisplayNameFor(m => m.EmailAddress)
@Html.TextBoxFor(m => m.EmailAddress, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.EmailAddress)
</div>
<div class="form-group">
@Html.DisplayNameFor(m => m.MobileNumber)
@Html.TextBoxFor(m => m.MobileNumber, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.MobileNumber)
</div>
<div class="form-group">
@Html.DisplayNameFor(m => m.NumberOfPeople)
@Html.TextBoxFor(m => m.NumberOfPeople, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.NumberOfPeople)
</div>
<div class="form-group">
@Html.DisplayNameFor(m => m.Date)
@Html.TextBoxFor(m => m.Date, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Date)
</div>
<div>
@Html.DisplayNameFor(m => m.Time)
@Html.TextBoxFor(m => m.Time, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Time)
</div>
}
</div>
<div class="form-group">
@Html.ActionLink("Book my table", "BookingDetails", "Booking" new { @class ="btn btn-primary" })
</div>
控制器:
// GET:
public ActionResult BookingDetails()
{
return View();
}
// Post
[HttpPost]
public ActionResult BookingDetails(BookingDetailsViewModel model)
{
if(ModelState.IsValid)
{
return RedirectToAction("BookingConfirmation");
}
return View(model);
}

我可以看到两个问题。
首先,您的按钮不是提交按钮。它是一个位于表单之外的链接。您必须将其移动到表单中并将其设置为提交按钮(或者编写一些在单击时提交表单的JavaScript):
<div>
@Html.DisplayNameFor(m => m.Time)
@Html.TextBoxFor(m => m.Time, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Time)
</div>
<input type="submit" class="btn btn-primary" /> <!-- move it inside the form -->
@* ^^^^ submit *@
} <!-- end of your form is here -->
此外,Html.ValidationSummary(true)
会隐藏验证摘要中的所有属性错误。这可能不是你想要的。如果您遇到该问题,请从通话中删除true
。
