我有这个代码来获取图表的数据：

function createData(data) {
    if ($("#options").val() == 1) {
        var totalTopProfit = eval(data.data[0].profit.replace(/[^\d\.]/g, '') + '+' + data.data[1].profit.replace(/[^\d\.]/g, '') + '+' + data.data[2].profit.replace(/[^\d\.]/g, '') + '+' + data.data[3].profit.replace(/[^\d\.]/g, '')).toFixed(2);
        var totalProfit = eval(data.others.replace(/[^\d\.]/g, ''));
        var othersProfit = parseFloat(totalProfit) - totalTopProfit;

        createLegend(data, othersProfit, 1);

        var data = [{
            "company": data.data[0].company,
            "profit": data.data[0].profit,
            "percentage": parseFloat(eval((data.data[0].profit.replace(/[^\d\.]/g, '') / totalProfit) * 100).toFixed(2))
        }, {
            "company": data.data[1].company,

            "percentage": parseFloat(eval((othersProfit / totalProfit) * 100).toFixed(2))
        }];
    }
    return data;
}

问题是当利润有负值时，它会打破图表。现在我需要检查是＆＃34;利润＆＃34; （＆＃34;利润＆＃34;：data.data [0] .profit）否定，如果是，那么我需要为具有负值的利润删除所有这些数据，并且在数据中仅返回具有正利润的数据

{
    "company": data.data[0].company,
    "profit": data.data[0].profit,
    "percentage": parseFloat(eval((data.data[0].profit.replace(/[^\d\.]/g, '') / totalProfit) * 100).toFixed(2))
}

有谁知道我怎么检查这个？

1 个答案:

答案 0 :(得分：1)

我认为你可以在javascript中使用过滤功能来实现这一点。

data=data.data.filter((d)=>{// as your data array is inside data object
return d.profit>=0;
})

现在你将只有正数或零利润的数据。
