Stacked Column Highcharts在IE 8中不起作用

Question

我在Ruby on Rails应用程序中使用 Jquery版本1.11和highcharts 4.0.1 。

堆叠列高图表在所有浏览器上运行良好，除了在IE8中抛出错误＆＃34; 对象不支持此属性或方法：eval代码，第1行字符3855 （Jquery.js第7060行第5个字符）＆＃34;

这是js代码：

    <%= javascript_tag do %>
  new Highcharts.Chart({
        chart: {
            renderTo: <%= render_div.to_json.html_safe  %>,
            type: 'column'
            },
            credits: {
               enabled: false
            },
            title: {
                text: <%= ("#{heading} Data Chart").to_json.html_safe %>
            },

            xAxis: {
                categories: <%= graph_months.to_json.html_safe %>
            },
            yAxis: {
                min: 0,
                stackLabels: {
                    enabled: false,
                    style: {
                        fontWeight: 'bold',
                        color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
                    }
                }
            },
            tooltip: {
                formatter: function() {
                    return '<b>'+ this.x +'</b><br/>'+
                        this.series.name +': '+ this.y +'<br/>'
                }
            },

            plotOptions: {
                column: {
                    stacking: 'normal',
                    dataLabels: {
                        enabled: true,
                        color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white',
                        style: {
                            textShadow: '0 0 3px black, 0 0 3px black'
                        },
                        formatter: function() {
                          if (this.y != 0) {
                            return this.y +'%';
                          } else {
                            return null;
                          }
                        }
                    }
                }
            },
            series: [{
                name: 'A',
