angular - 类型 'undefined' 不可分配给类型 'ApexAxisChartSeries | ApexNonAxisChartSeries'

Question

我在ts中用过这段代码

export type pieChartOptionss = {
  series?: ApexNonAxisChartSeries | '';
  chart?: ApexChart | '';
  legend?: ApexLegend | '';
  dataLabels?: ApexDataLabels | '';
  responsive?: ApexResponsive[] | '';
  labels?: any | '';
};
export class DashboardComponent implements OnInit {
 public pieChartOptionss!: Partial<pieChartOptionss>;
}
     (response: any) => {
          this.user_data = response.results;
          console.log('user_data', this.user_data)
          this.user_data_true = this.user_data.filter(x => x.is_active === true)
          this.user_data_false = this.user_data.filter(x => x.is_active === false)
          this.pieChartData = [this.user_data_true.length, this.user_data_false.length];
          this.pieChartOptionss = {
            series: [this.user_data_true.length, this.user_data_false.length],
            chart: {
              type: 'donut',
              width: 270,
            },
            legend: {
              show: false,
            },
            dataLabels: {
              enabled: true,
            },
            labels: ['Active', 'Inactive'],
            responsive: [
              {
                breakpoint: 480,
                options: {},
              },
            ],
          };
        }

在 html 中我使用了这段代码:

    <div class="body" *ngIf="pieChartOptionss">
          <apx-chart [series]="pieChartOptionss?.series" [chart]="pieChartOptionss?.chart"
            [labels]="pieChartOptionss?.labels" [responsive]="pieChartOptionss?.responsive"
            [dataLabels]="pieChartOptionss?.dataLabels" [legend]="pieChartOptionss?.legend" class="apex-pie-center">
          </apx-chart>
          <div class="table-responsive m-t-15">
            <table class="table align-items-center">
              <tbody>
                <tr>
                  <td><i class="fa fa-circle col-cyan mr-2"></i> {{ "active" | translate }}</td>
                  <td class="col-blue">{{pieChartOptionss?.series[0]}}</td>
                </tr>
                <tr>
                  <td><i class="fa fa-circle col-green mr-2"></i>{{ "inactive" | translate }}</td>
                  <td class="col-green">{{pieChartOptionss?.series[1]}}</td>
                </tr>
              </tbody>
            </table>
          </div>
        </div>

问题是，当我为项目提供服务时显示此错误:

110 {{pieChartOptionss?.series[1]}}

Answer 1

唯一对我有用的解决方案是添加单词“any”，如下面的代码所示:

public pieChartOptionss!: Partial<pieChartOptionss> | any;
