我如何访问 Html.ValidationMessage() 的文本以在 Razor 中检查它

Question

我有一些代码可以预订电影票。如果有人已经订了票，他可能会预订更多的票，只有当有特定的错误消息时。

此变量验证摘要仅接收标记 （ <span class="field-validation-valid" data-valmsg-for="Saving" data-valmsg-replace="true"></span> ）。但是在网页中@validationSummary打印正确的消息。我如何访问错误消息的文本进行检查？

@{
    @Html.ValidationSummary(true)
    var validationSummary = Html.ValidationMessage("Saving");
    bool buyAnotherVal = validationSummary.ToString().Contains("By continuing this form, you will booking another some tickets");
 }
 @using ( Html.BeginUmbracoForm<MovieBookingSurfaceController>( "SubmitBuyerDetails", new { buyAnother = buyAnotherVal }) )
 {
    @validationSummary

Answer 1

我解决了这个问题，所以：

@Html.ValidationSummary(true)
var validationSummary = Html.ValidationMessage("Saving");
bool bookAnotherVal = Html.ValidationSummary().ToString().Contains(BookingException.Msg_EmailDuplicatedBookAnother);

方法显示页面上所有验证消息的列表。（https://msdn.microsoft.com/en-us//library/system.web.mvc.html.validationextensions.validationsummary（v=vs.118）.aspx）
