ChartJs/React如何更新嵌套对象中嵌套对象的状态

state = {
  chartData: {
    labels: ['Red', 'Blue', 'Yellow'],
    datasets: [
      {
        label: 'My Dataset',
        data: [12, 19, 3]
      }
    ]
  }
};

render() {
  return (
    <div>
      <ChartJs data={this.state.chartData} />
    </div>
  );
}

updateChartData = () => {
  const newData = [5, 10, 8]; // 新的数据
  const updatedChartData = {
    ...this.state.chartData, // 复制原始状态对象
    datasets: [
      {
        ...this.state.chartData.datasets[0], // 复制原始嵌套对象
        data: newData // 更新数据
      }
    ]
  };

  this.setState({ chartData: updatedChartData }); // 更新状态
};

render() {
  return (
    <div>
      <ChartJs data={this.state.chartData} />
      <button onClick={this.updateChartData}>更新数据</button>
    </div>
  );
}
