Razor 为什么我在提交表单之前看到验证消息

我已经创建了一个表单，当我加载带有它的页面时，我会在提交表单之前看到验证消息。为什么？你可以

而

项

是局部视图：

@model MyMustAgreeValidation.Models.LabelEditorValidation
<div class="editor-label">
    @Model.Label
</div>
<div class="editor-field">
    @Model.Editor
    @Model.Validation
</div>

脚本包括：

 <script src="/Scripts/jquery-1.7.1.js"></script>        
 <script src="/Scripts/jquery.unobtrusive-ajax.js"></script>
 <script src="/Scripts/jquery.validate.js"></script>
 <script src="/Scripts/jquery.validate.unobtrusive.js"></script>
 <script src="/Scripts/Validation/EqualAttribute.js"></script>

EqualAttribute.js：

jQuery.validator.addMethod("equal", function (value, element, param) {
    if($(element).attr("type")=="checkbox")
    {
        value = String($(element).attr("checked"));
        param = param.toLowerCase();
    }
    return (value == param);
});

jQuery.validator.unobtrusive.adapters.addSingleVal("equal", "valuetocompare");

您是否在页面中包含了正确的validation.js文件？谢谢您的编辑。另一个“扔到墙上”，看看会发生什么想法：是否有任何自定义javascript会干扰输入，从而自动触发验证？非常好的代码。如果不使用自定义助手，是否存在问题？这应该是一个简单的测试。@TreyGramann在没有助手的情况下尝试：

@Html.LabelFor（m=>m.Password）@Html.EditorFor（m=>m.Password）@Html.ValidationMessageFor（m=>m.Password）

。相同的result@da7rutrak尝试禁用自定义非侵入性验证删除

。同样的结果

    public MvcHtmlString Label { get; set; }
    public MvcHtmlString Editor { get; set; }
