通过js将echarts柱状图内的数据转成excel

   dataView: {

                        show: true,

                        readOnly: false,

                        title: '数据视图',

                        optionToContent: function (opt) {

                            var axisData = opt.xAxis[0].data;

                            var series = opt.series;

                            var tdHeads = '<td  style="padding:0 10px">日期</td>';

                            series.forEach(function (item) {

                                tdHeads += '<td style="padding: 0 10px">' + item.name + '</td>';

                            });

                            var table = '<table border="1" class="data-view" style="margin-left:20px;border-collapse:collapse;font-size:14px;text-align:center"><tbody><tr>' + tdHeads + '</tr>';

                            var tdBodys = '';

                            for (var i = 0, l = axisData.length; i < l; i++) {

                                for (var j = 0; j < series.length; j++) {

                                    if (typeof(series[j].data[i]) == 'object') {

                                        tdBodys += '<td>' + series[j].data[i].value + '</td>';

                                    } else {

                                        tdBodys += '<td>' + series[j].data[i] + '</td>';

                                    }

                                }

                                table += '<tr><td style="padding: 0 10px">' + axisData[i] + '</td>' + tdBodys + '</tr>';

                                tdBodys = '';

                            }

                            table += '</tbody></table>';

                            return table;

                        }

                    }

导出来都只是图片了。。。没有像web那样的动态交互功能的。内置的图表也一样的
