Highcharts highchart自定义菜单，当我向下钻取和向上钻取自定义事件（contextmenu）不工作时

我正在使用highchart上下文菜单（使用：）并向下和向上钻取

问题：

  chart: {
    type: 'pie',
    events: {
      load: function () {
        var chart = this;

        chart.series[0].customEventsEnabled = true;
      }
    }
  },
  plotOptions: {
    series: {
      events: {
        contextmenu: function() {
          var series = this;

          if (series.customEventsEnabled || series.drilldownLevel) {
            console.log('working');
          }
        }
      }
    }
  }

当我右键单击饼图时，我们可以调用上下文菜单中的警报。同时，当我向下钻取和向上钻取，然后右键单击饼图时，contextmenu不起作用。在plotoption中工作正常，但我在plotoption中不需要它

此问题的解决方法是将事件添加到plotOptions，并检查事件是否发生在主系列上。检查下面发布的演示和代码

代码：

  chart: {
    type: 'pie',
    events: {
      load: function () {
        var chart = this;

        chart.series[0].customEventsEnabled = true;
      }
    }
  },
  plotOptions: {
    series: {
      events: {
        contextmenu: function() {
          var series = this;

          if (series.customEventsEnabled || series.drilldownLevel) {
            console.log('working');
          }
        }
      }
    }
  }

演示：

  chart: {
    type: 'pie',
    events: {
      load: function () {
        var chart = this;

        chart.series[0].customEventsEnabled = true;
      }
    }
  },
  plotOptions: {
    series: {
      events: {
        contextmenu: function() {
          var series = this;

          if (series.customEventsEnabled || series.drilldownLevel) {
            console.log('working');
          }
        }
      }
    }
  }
