javascript - 只有一个使用 react-grid-layout 的 highcharts 可以调整大小

Question

我正在使用 React-Grid-Layout 构建一个仪表板，该仪表板将由包含小部件(即图表、日历等)的网格组成。每个网格都可以拖动、响应和调整大小(网格中的小部件也会调整大小)。
我的代码；

import React, { Component } from "react";
import { Responsive, WidthProvider } from "react-grid-layout";
import ReactHighcharts from "react-highcharts";
import Highcharts from "highcharts/highstock";
import HighchartsReact from "highcharts-react-official";
import "./styles/styles.css";
const ResponsiveGridLayout = WidthProvider(Responsive);

const styles = {
  fontFamily: "sans-serif",
  textAlign: "center"
};

Live demo在此处的代码沙盒上。
只有一张图表可以根据网格高度和宽度的变化调整大小。看来我只是将尺寸更改传递给一个 div 而不是其余的。我如何让所有图表都遵循网格调整大小而不是一个？

Answer 1

您的引用仅指向最后创建的图表，您需要获取与调整大小事件相关的图表，例如通过回调引用:

export default class App extends Component {
  constructor(props) {
    super(props);
    this.myRef = React.createRef();
    this.conRef = React.createRef();

    this.chartRefs = [];

    this.setChartRef = (ref) => {
      this.chartRefs.push(ref);
    };
  }

  render() {
    const gridItems = [...];
    const layout = [...];

    return (
      <ResponsiveGridLayout
        ...
        onResizeStop={function (e, layout) {
          this.chartRefs[layout.i - 1].chart.reflow();
        }.bind(this)}
      >
        {gridItems.map((item, i) => {
          return (
            <div key={item.id} ref={this.conRef} className="grid-item">
              ...
              <HighchartsReact
                ref={this.setChartRef}
                containerProps={{ style: { width: "100%", height: "100%" } }}
                options={config}
                // highcharts={Highcharts}
              />
            </div>
          );
        })}
      </ResponsiveGridLayout>
    );
  }
}
