导入模块后 Highcharts drilldown 不起作用

Question

我是 react/ES6 的新手。我在 ES6 中使用 highcharts 4.2.4 并通过创建一个 highcharts 组件来响应：http://www.highcharts.com/blog/192-use-highcharts-to-create-charts-in-react。我正在使用 ES6 并将 highcharts 导入为 import Highcharts from 'highcharts' 其中 highcharts 是 package.json.

中提到的 npm 模块

我浏览了 highcharts 向下钻取示例。我根据向下钻取示例获取了图表：http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-drilldown/ 具有以下图表选项：

{
    chart: {
        type: 'column'
    },
    title: {
        text: 'Browser market shares. January, 2015 to May, 2015'
    },
    subtitle: {
        text: 'Click the columns to view versions.'
    },
    xAxis: {
        type: 'category'
    },
    yAxis: {
        title: {
            text: 'Total percent market share'
        }

    },
    legend: {
        enabled: false
    },
    plotOptions: {
        series: {

            }
        }
    },

            ]
        }]
    }
}

但是，我注意到尽管图表呈现良好，但单击任何列都不会触发向下钻取。但是，如果不是像上面那样导入 Highcharts 并包含以下行：

<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/drilldown.js"></script>

在 index.html 中，向下钻取进行得很好。我什至尝试在高图表组件中包含以下内容：

从 /highcharts/modules/drilldown.js'

导入 {drilldown}

但无济于事。您能否建议我哪里出错了以及如何获取 highcharts 组件 运行 drilldown？

Answer 1

正如 highcharts 博客文章所建议的，您需要加载可选模块。他们将它们作为道具发送，但您可以这样做：

import React from 'react';
import { findDOMNode } from 'react-dom';
import Highcharts from 'highcharts';
import drilldown from 'highcharts-drilldown';

const Highchart = React.createClass({
  componentDidMount() {
    // load modules
    drilldown(Highcharts);

    this.chart = new Highcharts['Chart'](
      findDOMNode(this),
      this.props.options
    );
  },

  componentWillUnmount: function () {
    this.chart.destroy();
  },

  render() {
    return (
      <div className="in-highchart"></div>
    )
  }
});

export default Highchart;

我遇到了同样的问题，这对我有用。
