Vue中实现 highchart 图表的导出功能

  
import Highcharts from "highcharts";
import Highcharts from "highcharts/highstock"; //缩略轴
import stockInit from "highcharts/modules/stock";
//highcharts 导出功能模块文件
import loadExporting from "highcharts/modules/exporting.js";
stockInit(Highcharts);
loadExporting(Highcharts);


// 导出图表
exportChart() {
  //文件名
  const imgName = this.chartParam.subReport.name;
  //导出时间
  const time = new Date(+new Date() + 8 * 3600 * 1000) 
    .toISOString()                                       //2021-10-19T10:20:07.880Z
    .replace(/:/g, "")
    .replace(/-/g, "")
    .replace(/T/g, "_")
    .replace(/\.[\d]{3}Z/, "");
  this.chart &&
    this.chart.exportChart({
      type: "image/png",
      filename: imgName + "_" + time
    });
}
