视图上未显示验证错误消息
Posted
技术标签:
【中文标题】视图上未显示验证错误消息【英文标题】：validations error messages not showing on the view 【发布时间】：2017-10-19 07:57:56 【问题描述】：我已经在我的 MVC 页面中实现了一个 mvc kendo 窗口控件，并且表单验证似乎确实有效。我可以在控制器中将模型状态设置为 false，但视图似乎没有显示消息。请注意，WorkLogType、WorkLog Subject 和 Details 是必填字段。我已经在视图模型中设置了所需的属性。我还在视图中为各个控件设置了验证标记。有什么问题？
这是我的代码

【问题讨论】：
如何在问题中加载视图？通过 ajax？ 是的。使用 ajax 【参考方案1】：在您的视图中添加这些行：
<script>
$(document).ready(function()
var form = $('form') // Give Id prop to your from
.removeData("validator")
.removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse(form);
);
<script>
还要确保将 jquery.validate.js 和 jquery.validate.unobtrusive.js 添加到您的 View cshtml 中，以便验证正常工作。
【讨论】：
嗨尝试了以下@using (Ajax.BeginForm("ActivityWorkLog_Create", "Activity", new AjaxOptions HttpMethod = "POST", OnSuccess = "OnSuccess", OnFailure = "OnFailure" ,new id = "ActivityWorkLogForm" )) function OnSuccess(response) $("#statusMessage").text("状态更新");警报（“成功”）； var form = $("#ActivityWorkLogForm") .removeData("validator") .removeData("unobtrusiveValidation"); $.validator.unobtrusive.parse(form); 我在成功被调用时看不到我的警报。你确定当model.state返回false时调用成功吗 不，我的意思是您如何加载视图而不是视图中的提交功能。您使用控制器操作返回视图？ 是的，我使用控制器动作返回视图以上是关于视图上未显示验证错误消息的主要内容，如果未能解决你的问题，请参考以下文章
