在 Visual Studio 2017 Angular 7 项目中，我使用的是 PrimeNG 版本 6.1.7。我有一个包含多个子组件的组件，其中一些子组件使用 PrimeNG 日历。截至 2019 年 3 月 6 日，这完全没有问题，当时我将工作代码交付给了客户。
但是，如果我从代码库中提取相同的代码并立即运行应用程序，则单击输入元素只会显示此元素呈现的灰色叠加层：
<div class="ui-widget-overlay ui-datepicker-mask ui-datepicker-mask-scrollblocker" style="z-index: 1002;"></div>
在 chrome 中调试时，如果我单击另一个应用程序（甚至是 Chrome 的 DevTools 窗口，从主窗口中取消停靠），然后单击覆盖，突然日期选择器显示，同时我看到，在 DevTools 的 Elements 选项卡中，以下 html 位于上面引用的 div 的正下方：
<div class="ng-trigger ng-trigger-overlayAnimation ng-tns-c23-2 ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-shadow ui-datepicker-touch-ui ng-star-inserted" ng-reflect-ng-class="[object Object]" style="z-index: 1004; transform: translate(-50%, -50%); opacity: 1;">
!-- TONS OF HTML FOR THE DATEPICKER -->
</div>
如前所述，我没有更改任何内容，所以我猜这是通过更新我的 package.json 文件中的每个设置所做的一些更改。
我一生都无法弄清楚发生了什么。如果我删除“touchUI = true”属性，那么日历确实会出现，但它没有在屏幕上正确居中（这是一个适合移动设备的应用程序）。任何帮助将非常感激。
一个示例日期控件（应用程序中的所有控件都有相同的问题）：
<p-calendar [(ngModel)]="labor.laborServiceDate" [touchUI]="true"></p-calendar>
