验证错误消息未显示在视图上

Question

我在我的 MVC 页面中实现了一个 mvc kendo window 控件，并且表单验证似乎有效。我可以在控制器中将模型状态设为 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必需的属性。我还在视图中为各个控件设置了验证标记。有什么问题吗？

这是我的代码

Answer 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 添加到您的视图 cshtml 中，以便验证正常工作。
