【问题描述】：

我的 _Layout.cshtml 文件中有一个带有以下标记的 Razor Pages 应用程序。

<li class="nav-item dropdown">
    <a class="nav-link text-dark dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
        Reports
    </a>
    <div class="dropdown-menu" aria-labelledby="navbarDropdown">
        <a class="dropdown-item" asp-area="Reports" asp-page="/Invoice/Index">Invoices</a>
        <div class="dropdown-divider"></div>
        <a class="dropdown-item" asp-area="Reports" asp-page="/ProfitabilityByCustomer/Index">Profitability by Customer</a>
        <a class="dropdown-item" asp-area="Reports" asp-page="/ProfitabilityByLocation/Index">Profitability by Location</a>
        <a class="dropdown-item" asp-area="Reports" asp-page="/CostAudit/Index">Cost Audit</a>
        <a class="dropdown-item" asp-area="Reports" asp-page="/ChangeLogs/Index">Change Logs</a>
    </div>
</li>

注意最后一个链接（到 /ChangeLogs/Index）。此页面有一个页面路由 (@page "{id?}")。

当我手动导航到 /Reports/ChangeLogs/61 时，上面的标记呈现为：

<li class="nav-item dropdown">
    <a class="nav-link text-dark dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
        Reports
    </a>
    <div class="dropdown-menu" aria-labelledby="navbarDropdown">
        <a class="dropdown-item" href="/Reports/Invoice">Invoices</a>
        <div class="dropdown-divider"></div>
        <a class="dropdown-item" href="/Reports/ProfitabilityByCustomer">Profitability by Customer</a>
        <a class="dropdown-item" href="/Reports/ProfitabilityByLocation">Profitability by Location</a>
        <a class="dropdown-item" href="/Reports/CostAudit">Cost Audit</a>
        <a class="dropdown-item" href="/Reports/ChangeLogs/61">Change Logs</a>
    </div>
</li>

不知何故，当前页面是 /Reports/ChangeLogs/61，导致菜单中的链接以该路由值呈现！

我无法解释。我需要阻止它发生。

【解决方案1】：

如果没有指定，路由将从当前页面继承值。所以指定一个空白值；

<a class="dropdown-item" asp-area="Reports" asp-page="/ChangeLogs/Index" asp-route-id="">Change Logs</a>

【讨论】：

是的，解决了它。但我仍然不确定它为什么要继承它们。我认为没有充分的理由。
