问题描述
当我单击在视图上提交"时,系统将重定向到新视图.如果验证失败,系统将重定向到同一页面,突出显示字段.但是,我还要求系统显示带有错误消息的标签.
When I click submit on view, the system redirects to a new view. If validation fails, the system redirects to the same page highlighting the fields. However, I also require the system to show a label with the error message.
<label for="label6" style="color:red; font-weight:normal !important; visibility: hidden">
The Corporate Email, FEIN or SSN does not match.<br /><br />
<span style="margin-left: 10%"></span>The following might be the case:<br />
<span style="margin-left: 12%"></span>- The Corporate Email entered is wrong. Please check the Corporate Email.<br />
<span style="margin-left: 12%"></span>- The FEIN entered is wrong. Please check the FEIN.<br />
<span style="margin-left: 12%"></span>- The SSN entered is wrong. Please check the SSN.<br />
<span style="margin-left: 12%"></span>- Please verify whether FEIN or SSN entered during registration.<br />
<span style="margin-left: 16%"></span>If you have registered using FEIN please submit using FEIN.<br />
<span style="margin-left: 16%"></span>If you have registered using SSN please submit using SSN.<br />
</Label>
有人可以帮我吗?
推荐答案
在控制器中
public ActionResult Index()
{
if (ModelState.IsValid)
{
//do something
return Redirect("/yournewpage");
}
if (!someChecks)
{
ModelState.AddModelError("", "Your custom error");
}
if (!someChecks2)
{
ModelState.AddModelError("", "Your custom error 2");
}
return View();
}
您可以在视图中使用
<p>
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<p>
