如何让 PrimeNg VirtualScroller 响应高度?

How to make PrimeNg VirtualScroller responsive height?

我有一个 primeng VirtualScroller,它有一个 属性 固定高度的 scrollHeight。我试图将 100% 设置为 value 但它不接受。还尝试向组件添加样式或 class 以将高度设置为 100%,但效果不佳。如何使高度与浏览器的高度相同window?

<p-virtualScroller [value]="lazyCars" scrollHeight="40em" [itemSize]="150" [rows]="50" [cache]="false"
                   [lazy]="true" (onLazyLoad)="loadCarsLazy($event)" [totalRecords]="totalLazyCarsLength">
  <ng-template let-car pTemplate="item" let-i="index">
    <div class="ui-g car-item mt-1">
      <div class="ui-g-12 ui-md-2">
        <div class="ui-g-12 ui-md-12" style="font-size: 11px; text-align: center; padding-top: 18px">{{ generateDate() | date: 'dd/MM/yyyy' }}</div>
        <div class="ui-g-12 ui-md-12" style="font-size: 24px; text-align: center; padding-top: 18px">{{ generateDate() | date: 'HH:mm:ss' }}</div>
      </div>
      <div class="ui-g-12 ui-md-2" style="display: flex">
        <img class="rounded-image" src="../../assets/images/profileplaceholder.jpg" width="115" height="100" />
        <!--<i style="font-size: 5rem; align-self: center;" class="pi pi-users mx-auto"></i>-->
      </div>
      <div class="arrow-left"></div>
      <div class="ui-g-12 ui-md-5 chat-window">
        <div class="ui-g">
          <div class="ui-g-10 ui-sm-6">Autor: {{car?.autor}}</div>
          <h2 class="ui-g-10 ui-sm-6 ml-2">Evento: {{car?.evento}}</h2>
        </div>
      </div>
    </div>
  </ng-template>
  <ng-template let-car pTemplate="loadingItem">
    <div class="ui-g car-item empty-car-item">
      <div class="ui-g-12 ui-md-2">
        <div class="empty-car-item-index"></div>
      </div>
      <div class="ui-g-12 ui-md-2">
        <div class="empty-car-item-image"></div>
      </div>
      <div class="ui-g-12 ui-md-8">
        <div class="ui-g">
          <div class="ui-g-12"><div class="empty-car-item-text"></div></div>
          <div class="ui-g-12"><div class="empty-car-item-text"></div></div>
          <div class="ui-g-12"><div class="empty-car-item-text"></div></div>
          <div class="ui-g-12"><div class="empty-car-item-text"></div></div>
        </div>
      </div>
    </div>
  </ng-template>
</p-virtualScroller>

这可以使用嵌套的 flexbox 来完成。我已经在 中解释了它们如何与 Angular 一起工作。将该解决方案应用于此问题涉及将 flexbox-middle class 的等价物应用于组成虚拟滚动区域的每个元素:

p-virtualScroller, 
/deep/ .ui-virtualscroller, 
/deep/ .ui-virtualscroller-content, 
/deep/ .ui-virtualscroller-list, 
/deep/ cdk-virtual-scroll-viewport {
  display        : flex;
  flex           : 1;
  flex-direction : column;
}

使用该样式,不应再设置 p-virtualScroller 元素的 scrollHeight 属性,因为组件将弯曲到父元素的高度:

<p-virtualScroller [itemSize]="50" [value]="items">
  <ng-template pTemplate="item" let-obj>
    {{ obj.name }}
  </ng-template>
</p-virtualScroller>
