MVC model的验证错误以弹出框的方式显示

1、前台

eg

@using (Html.BeginForm("Register", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post)) { @Html.AntiForgeryToken() @Html.ValidationSummary(true) <span> <i class="per"></i> @Html.TextBoxFor(m => m.FamilyName, new { @id = "user-lastName", maxlength = "25", @class = "z-w289 J-fname", @placeholder = "姓" }) </span> <span style="margin-left: 3px;"> <i class="per"></i> @Html.TextBoxFor(m => m.FirstName, new { @id = "user-lastName", maxlength = "25", @class = "z-w289 J-sname", @placeholder = "名" })

</span>

}

2、Js

$(function () { $(".validation-summary-errors").hide();

var timer = setTimeout("showMessage()", 600); });

function showMessage() { var text = $.trim($(".validation-summary-errors").text()); if (text != "") { alert(text); return; }

}

3、后台

try { if (ModelState.IsValid) {

。。。

}

var errorMessage = string.Empty; if (ModelState != null && ModelState.Count > 0) { foreach (var item in ModelState) { if (!string.IsNullOrEmpty(errorMessage)) { break; }

if (item.Value.Errors.Count > 0 && item.Value.Errors.FirstOrDefault() != null && !string.IsNullOrEmpty(item.Value.Errors.FirstOrDefault().ErrorMessage)) { errorMessage = item.Value.Errors.FirstOrDefault().ErrorMessage; ModelState.AddModelError("", errorMessage); break; } } }
