highcharts javascript變量

Question

我正在使用highcharts以嘗試以季度間隔構建散點圖。

這裏是我的代碼：

 laboreff = ''; 
      if ($.isArray(dataItem.content)) { 
      for (var i = 0, max = dataItem.content.length; i < max; i += 1) { 
       laboreff += '{"x:Date.UTC('+'"'+dataItem.content[i].FiscalYear + '" ' + ', ' + '"' + dataItem.content[i].FiscalQuarter + '"'+'),"y":' + '"'+ dataItem.content[i].AverageLaborEfficiencyRatiobySICCode + '"'+'},'; 
      } 
      } 

      var laboreff = laboreff; 
      var jannes = '[Date.UTC(2007,0,1),72634],[Date.UTC(2007,3,1),72634],[Date.UTC(2007,6,1),72634],[Date.UTC(2007,9,1),72634]'; 
//var jannes = JSON.parse("[" + jannes + "]") 
// var laboreff = $.parseJSON(laboreff); 
     //console.log(laboreff); 
      Highcharts.setOptions({

       alert(laboreff); 
       console.log(jannes); 
     } 
     } 
    } 
        ); 
    } 
        ); 
</script> 

變量laboreff得到正確的內容，當我粘貼控制檯的價值的把它加載一系列數據，我已經試過Json.parse但因爲它不是有效的JSON不工作。任何想法爲什麼圖不加載變量？

如果我從控制檯中將變量jannes和laboreff的值複製粘貼到數據中，它就可以工作。

你能試試這個：

var laboreff = []; 

if ($.isArray(dataItem.content)) { 
    for (var i = 0, max = dataItem.content.length; i < max; i += 1) { 
     laboreff.push({ 
      x: new Date(dataItem.content[i].FiscalYear).getTime(), 
      y: dataItem.content[i].FiscalQuarter 
     }); 
    } 
}
