的输入变量的

setter/ngOnChanges方法仅被调用一次？ ngOnChanges仅在第一次selectedRow触发数据时才提供控制台输出。如果selectedRow的值未更改，则更改ngOnChanges。

子图表组件：

component

父组件html：

export class ChartComponent implements OnInit, OnChanges {

  @Input() chartData;

  ngOnChanges(changes: SimpleChanges) { 
    console.log(changes);
  }

}

父组件：

<app-chart [chartData]="chartData" ></app-chart>

子组件的输入变量的setter / ngOnChanges方法仅被调用一次？
