angular - *ngFor flexbox 行方向

Question

在 Angular 5 中，*ngFor生成 <div>列方向而不是行方向的元素:

html :

    <div class="charts"  *ngFor="let chart of chartEntities$ | async; let i = index; trackBy: trackByFn"
          style="padding-top: 0.5em">
          <div class="item">
            <span style="background-color: rgb(127, 140, 255); height:120px;"> number {{i}}
            </span>
          </div>
    </div>

css :

    .charts{
      display: flex;
     flex-direction: row;
    }

    .item{
      display: flex;
      flex: 1
    }

如何将其更改为所有元素都在同一行中？

谢谢

Answer 1

你应该重新排列为

<div class="charts" style="padding-top: 0.5em">
      <div class="item" *ngFor="let chart of chartEntities$ | async; let i = index; trackBy: trackByFn">
        <span style="background-color: rgb(127, 140, 255); height:120px;"> number {{i}}
        </span>
      </div>
</div>

display: flex; flex-direction: row;应该在父 div 上
