highchart接收后台数据用法

最近做数据分析的时候使用了highchart这个插件，从后台中接收数据的时候出了一些问题，记录下来免得以后忘了。

$(function () {
        var list = {$weeklist};
        var weekobj1 = eval(list);
        var  week="";
        //alert(obj1.length);
        for(var i=0;i<weekobj1.length;i++)
        {
            week = week+"\'"+weekobj1[i].weekname+"\',";
        }
        //console.log(week);
        week = "["+week+"]";
        var weekobj = eval(week);
        //缺勤次数
        var count1 = {$weekcount};
        var weekcountobj1 = eval(count1);
        var  weekcount="";
        for(var i=0;i<weekcountobj1.length;i++)
        {
            weekcount = weekcount+weekcountobj1[i].count+",";
        }
        console.log(weekcount);
        weekcount = "["+weekcount+"]";
        var weekcountobj = eval(weekcount);
    $('#container').highcharts({
        chart: {
            type: 'column'
        },
        title: {
            text: '{$name}各周缺勤次数'
        },
        xAxis: {
            categories: weekobj
        },
        yAxis: {
            min: 0,
            title: {
                text: '次数'
            }
        },

        tooltip: {
            headerFormat: '<span style="font-size:10px">{point.x}:</span><table>',
            pointFormat: '<tr><td style="padding:0"><b>{point.y:.if}</b></td></tr>',
            footerFormat: '</table>',
            shared: true,
            useHTML: true
        },
        plotOptions: {
            column: {
                pointPadding: 0.2,
                borderWidth: 0
            }
        },
        credits: {
  enabled: false
},
        series: [{
            name: '123',
            id:'test',
            data: weekcountobj
        }]
    });
    var chart = $('#container').highcharts();
    $(".highcharts-legend-item").hide();

问题其实很简单，highchart接收数据时候只能是javascript对象不是javascript字符串，所以要使用eval进行转换。标红部分
