Question

有关高位图表，请参见下面的json {“ chart”：{“ type”：“ column”}，“贷方”：{“ enabled”：true，“ href”：“＃”，“ position”：{“ align”：“ right”，“ verticalAlign” ：“底部”，“ y”：0}，“文本”：“ www.midasplus.com”}，“系列”：[{“颜色”：{“ linearGradient”：{“ x1”：1，“ x2” ：0，“ y1”：0，“ y2”：1}，“停止”：[[0，“＃9a1919”]，[“ 0.25”，“＃9a1919”]，[“ 0.5”，“＃9a7319” ]，[“ 0.75”，“＃9a1919”]，[1，“＃9a1919”]]}，“数据”：[“ -1.03”，“-3.01”，“-2.25”，“ 0.63”，“- 1.07“，” 1.14“，”-0.38“，” 2.03“，”-2.07“，”-3.55“，”-3.99“，”-0.41“]，” negativeColor“：{” linearGradient“：{” x1“ ：-1，“ x2”：0，“ y1”：0，“ y2”：-1}，“停止”：[[0，“＃199A19”]，[“ 0.25”，“＃199A19”]，[ “ 0.5”，“＃00CC00”]，[“ 0.75”，“＃199A19”]，[1，“＃199A19”]]}，“ showInLegend”：“ false”}]，“ title”：{“ text” ：“ Control Chart”}，“ xAxis”：{“类别”：[“ Q3 2013”，“ Q4 2013”，“ Q1 2014”，“ Q2 2014”，“ Q3 2014”，“ Q4 2014”，“ Q1 2015 “，” 2015年第二季度“，” 2015年第三季度“，” 2015年第四季度“，” 2016年第一季度“，” 2016年第二季度“]}}

在此，我需要更改“数据”：[“ -1.03”，“-3.01”，“-2.25”，“ 0.63”，“-1.07”，“ 1.14”，“-0.38”，“使用JavaScript，将2.03“，”-2.07“，”-3.55“，”-3.99“，”-0.41“]字符串数组值转换为同一json中的整数数组。

const data = {"chart": {"type": "column"},"credits": {"enabled": true,"href": "#","position": {"align": "right","verticalAlign": "bottom","y": 0},"text": "www.midasplus.com"},"series": [{"color": {"linearGradient": {"x1": 1,"x2": 0,"y1": 0,"y2": 1},"stops": [[0,"#9a1919"],["0.25","#9a1919"],["0.5","#9a7319"],["0.75","#9a1919"],[1,"#9a1919"]]},"data": ["-1.03","-3.01","-2.25","0.63","-1.07","1.14","-0.38","2.03","-2.07","-3.55","-3.99","-0.41"],"negativeColor": {"linearGradient": {"x1": -1,"x2": 0,"y1": 0,"y2": -1},"stops": [[0,"#199A19"],["0.25","#199A19"],["0.5","#00CC00"],["0.75","#199A19"],[1,"#199A19"]]},"showInLegend": "false"}],"title": {"text": "Control Chart"},"xAxis": {"categories": ["Q3 2013","Q4 2013","Q1 2014","Q2 2014","Q3 2014","Q4 2014","Q1 2015","Q2 2015","Q3 2015","Q4 2015","Q1 2016","Q2 2016"]} }    
const floatArr = data.series[0].data.map(item => {
    return parseFloat(item)
})

如果您希望将它们作为整数，请将函数parseInt(item, 10)与parseFloat(item)一起使用。
