asp.net-core - ValidationSummary.ModelOnly 失败，但 ValidationSummary.All 有效

Question

这很奇怪。由于某种原因，这失败了:

<div asp-validation-summary="ValidationSummary.ModelOnly"></div>

但这个工作得很好:

<div asp-validation-summary="All"></div>

有谁知道为什么？这是整个代码片段:

<div class="row">
<div class="col-md-6 col-md-offset-3">
    <h3>Login</h3>
    <form method="post" novalidate>
        <div asp-validation-summary="All"></div>
        @*<div asp-validation-summary="ValidationSummary.ModelOnly"></div>*@
        <div class="form-group">
            <label asp-for="Username"></label>
            <input type="text" asp-for="Username" class="form-control" />
            <span asp-validation-for="Username"></span>
        </div>
        <div class="form-group">
            <label asp-for="Password"></label>
            <input type="password" asp-for="Password" class="form-control" />
            <span asp-validation-for="Password"></span>
        </div>
        <div class="form-group">
            <input type="submit" value="Login" class="btn btn-success" />
        </div>
    </form>
</div>

Answer 1

我假设您使用的是 asp.net core 1.0。验证摘要标签助手的值已从

<div asp-validation-summary="ValidationSummary.ModelOnly"></div>

简单地

<div asp-validation-summary="ModelOnly"></div>

你用 All 做了正确的事;-)
