我正在尝试在我的 Web 应用程序中创建一个带有 Highcharts 的条形图，该应用程序在前端使用 React。下面是我的 dashboard.tsx 文件的片段，我基本上只是从 JSFiddle ( http://jsfiddle.net/8qjcz4q0/ ) 中复制并粘贴了代码，该代码使用 Highcharts 呈现了一个简单的条形图，但由于某种原因它不是工作，我在控制台中收到一个错误（Highcharts 错误 #13），渲染 div 没有显示。

 import * as React from "react";
 import * as ReactDOM from "react-dom";
 import * as Highcharts from "highcharts";

 Highcharts.chart('container', {
   chart: {
    type: 'column'
   },
  title: {
    text: 'World\'s largest cities per 2014'
   },
 subtitle: {
    text: 'Source: Wikipedia'
  },
  xAxis: {
    type: 'category',
    labels: {
        rotation: -45,
        style: {
            fontSize: '13px',
            fontFamily: 'Verdana, sans-serif'
        }
      }
   },
   yAxis: {
    min: 0,
    title: {
        text: 'Population (millions)'
    }
   },
legend: {
    enabled: false
},
tooltip: {
    pointFormat: 'Population in 2008: <b>{point.y:.1f} millions</b>'
},
series: [{
    name: 'Population',
    data: [
        ['Shanghai', 23.7],
        ['Lagos', 16.1],
        ['Istanbul', 14.2],
        ['Karachi', 14.0],
        ['Mumbai', 12.5],
        ['Moscow', 12.1],
        ['São Paulo', 11.8],
        ['Beijing', 11.7],
        ['Guangzhou', 11.1],
        ['Delhi', 11.1],
        ['Shenzhen', 10.5],
        ['Seoul', 10.4],
        ['Jakarta', 10.0],
        ['Kinshasa', 9.3],
        ['Tianjin', 9.3],
        ['Tokyo', 9.0],
        ['Cairo', 8.9],
        ['Dhaka', 8.9],
        ['Mexico City', 8.9],
        ['Lima', 8.9]
    ],

 }]
});
render() {
     return ( <div>
        <div id="container"></div>
        </div>
    );
  }
}

我怀疑 HTML id 属性不适用于 React，但我不知道 Highcharts 是否可以渲染到类而不是 id。

为了在这里回答我自己的问题，在 highcharts 尝试查找 div 之后调用了 render 函数。您可以将图表渲染代码放在 componentDidMount() 部分，直接使用 dangerouslySetInnerHTML 渲染 highcharts 代码，或者在 highcharts 代码上设置计时器。对于另一个答案，将 div 标签粘贴在我的 html 中的问题是我正在渲染 JSX 中的所有其他内容，因此想从我的 JSX 中渲染我的图表。

ReactDOM.render(
