Question

如何使用amd模块通过脱机导出到pdf的图表（Highcharts）？ Require jsPDF模块“有时”抛出requirejs不匹配的错误或弄乱了其他require的回调引用。

var chart;
require(['highcharts', 'highcharts/modules/exporting', 'highcharts/modules/offline-exporting', 'jsPDF', 'svg2pdf'], function(Highcharts, a, b, jsPDF, svg2pdf) {
    window.jsPDF = jsPDF.default;
    window.svg2pdf = svg2pdf;
    chart = Highcharts.chart('container', {

    exporting: {
      libURL: 'https://code.highcharts.com/7.1.1/lib'
    },

    series: [{
      data: [3, 4, 5, 3, 2]
    }]

  });
});

Answer 1

问题来自jsPDF： https://github.com/yWorks/jsPDF

我为所有define语句设置了一个名称，因此不再有匿名模块定义。现在可以了。

第3行示例

之前：

typeof define === 'function' && define.amd ? define(['exports'], factory) :

之后：

typeof define === 'function' && define.amd ? define('jsPDF', ['exports'], factory) :

您可以像这样设置离线导出

exporting: {
        chartOptions: {
            plotOptions: {
                series: {
                    dataLabels: {
                        enabled: true
                    }
                }
            }
        },
        fallbackToExportServer: false
    }
