Question

我试图根据季度系统得到总数的总和。

data= [{
    "rowLabel": "Label",
    "previousYearSpend": "21239481.8",
    "janActual": "13146105.51",
    "janPlan": "13126631.26",
    "febActual": "129458614.21",
    "febPlan": "12440428.3",
    "marActual": "15269255.37",
    "marPlan": "1497070.55",
    "aprActual": "16996329.67",
    "aprPlan": "15683061.15",
    "mayActual": "13736166.96",
    "mayPlan": "14847570.78",
    "junActual": "135525666.19",
    "junPlan": "14849827.86",
    "julActual": "",
    "julPlan": "15908197.25",
    "augActual": "",
    "augPlan": "",
    "sepActual": "",
    "sepPlan": "",
    "octActual": "",
    "octPlan": "",
    "novActual": "",
    "novPlan": "",
    "decActual": "",
    "decPlan": ""
}]

我要找的结果是

    "marActual": "15269255.37",
    "marPlan": "1497070.55",
    "aprActual": "16996329.67",
    "aprPlan": "15683061.15",
    "mayActual": "13736166.96",
    "mayPlan": "14847570.78",
    "junActual": "135525666.19",
    "junPlan": "14849827.86",
    "julActual": "",
    "julPlan": "15908197.25"

其中marActual = janActual+febActual+marActual marPlan = janPlan+febPlan+marPlan

我将日期作为 '2015/JUN/01'，结果应为Q1, APR, MAY, JUN 如果我将日期作为'2015/JUL/1'传递，则应为Q1, Q2, JUL 其中junActual = aprActual+mayActual+junActual 和junPlan = aprPlan+mayPlan+junPlan

我对我必须对值fiddle求和的逻辑感到困惑。我的数据表是基于这些数据构建的，它动态创建表并使用此json呈现表。

这是一个解决方案，但它有点笨重：/我会看看我是否可以清理它。

data= [{
    "rowLabel": "Label",
    "previousYearSpend": "21239481.8",

    }
    return([String(totaQ1), String(totaQ2), String(totaQ3), String(totaQ4)]);

}

quarterPlan = function() {

quarterlyReport = function(date){ // date can be in your format, '2015/JUN/01', or even just the abbreviation
    date = date.toLowerCase();
    monthsCorrect = ['jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec']; //store months in correct order
    quarterReport = {}; // the quarter report
    // find which month to stop at using regular expression
    for (i = 0; i < monthsCorrect.length; i++){
        var monRegEx = RegExp(monthsCorrect[i]);
        var test = monRegEx.test(date);
        if (test == true){break;}
    }
    var monthStop = i; //index that for loop above stopped at
    included = monthsCorrect.slice(0,monthStop + 1); // months to report back

    if(included.length == 3){
        quarterReport.Q1Actual = quarterActual()[0];
        quarterReport.Q1Plan = quarterPlan()[0];

        } else if (included.length > 3 && included.length <= 6){
        quarterReport.Q1Actual = quarterActual()[0];
        quarterReport.Q1Plan = quarterPlan()[0];
        // report months after Q1
        monthsAfter = monthsCorrect.slice(Q1.length, included.length)
        for (m = 0; m < monthsAfter.length; m++){
            act = monthsAfter[m] + 'Actual';
            pl = monthsAfter[m] + 'Plan';
            quarterReport[act] = data[0][act];
            quarterReport[pl] = data[0][pl];
        }

        }  else if (included.length > 6 && included.length <= 9){
            quarterReport.Q1Actual = quarterActual()[0];
            quarterReport.Q1Plan = quarterPlan()[0];
            quarterReport.Q2Actual = quarterActual()[1];
            quarterReport.Q2Plan = quarterPlan()[1];

            monthsAfter = monthsCorrect.slice(Q1.length*2, included.length)
            for (n = 0; n < monthsAfter.length; n++){
                act = monthsAfter[n] + 'Actual';
                pl = monthsAfter[n] + 'Plan';

            }

        } else if (included.length > 9 && included.length <= 12){
            quarterReport.Q1Actual = quarterActual()[0];
            quarterReport.Q1Plan = quarterPlan()[0];
            quarterReport.Q2Actual = quarterActual()[1];
            quarterReport.Q2Plan = quarterPlan()[1];

                pl = monthsAfter[n] + 'Plan';
                quarterReport[act] = data[0][act];
                quarterReport[pl] = data[0][pl];
            }

        } else {
            for(var j = 0; j < included.length; j++){
                actual = included[j] + 'Actual';
                plan = included[j] + 'Plan';
                quarterReport[actual] = data[0][actual];
                quarterReport[plan] = data[0][plan];
            }
        }

    return(quarterReport);

}
console.log(quarterlyReport('2015/JUN/01'));

6月份，这将返回：

{Q1Actual: "157873975.09" 
Q1Plan:"27064130.110000003"
aprActual:"16996329.67"
aprPlan:"15683061.15"  
junActual:"135525666.19" 
junPlan:"14849827.86" 
mayActual: "13736166.96"       
mayPlan: "14847570.78"}

顺便说一句，我运行了你的脚本，如果March应该返回累计总数，那么我认为Q1actual（marActual）的数量是错误的。我加起来是1月，2月和3月，结果是我在Q1Actual上的总数。

这是我提出的解决方案，如果有比我更好的解决方案，我将使用该代码fiddle

var aMonths = ["jan", "feb", "mar",
               "apr", "may", "jun",
               "jul", "aug", "sep",
               "oct", "nov", "dec"],
    data= [{

console.log(sumByQuarter('2015/APR/01',  data, aMonths));

function sumByQuarter(date, data, aMonths) {
    //console.log(data);
    var today = new Date(date) || new Date(),
        QUARTER = 3,
        month = today.getMonth(),
        limit = (month > aMonths.length) ? aMonths.length : month,
        aData = [],
        tempMonths = aMonths.slice(),
        sumActual = 0;
        sumPlan = 0;
    tempMonths.splice(limit + 1, Number.MAX_VALUE);

    var aQuarter = []; // quater array
    var sumjson = {};
    for(i = 0; i < limit; i++) {
        sumActual += parseFloat(data[0][tempMonths[i]+'Actual']);

            aQuarter.push(tempMonths[i]);
            sumActual = 0;
            sumPlan = 0;
        }
    }
    console.log(sumjson);
    var usedElements = aQuarter.length * QUARTER;
    if(tempMonths.length > usedElements) {
        aQuarter = aQuarter.concat(tempMonths.slice(usedElements));        
    }
    //console.log(aQuarter);
    for(j = 0; j < data.length; j++) {
        var json = {};
        for(i = 0; i < aQuarter.length; i++) {
            json['rowLabel'] = data[j]['rowLabel'];
            json['previousYearSpend'] = data[j]['previousYearSpend'];         
            json[aQuarter[i]+'Actual'] = typeof sumjson[aQuarter[i] + 'Actual'] != 'undefined' ? sumjson[aQuarter[i] + 'Actual'] : data[j][aQuarter[i] + 'Actual'];
            json[aQuarter[i]+'Plan'] = typeof sumjson[aQuarter[i] + 'Plan'] != 'undefined' ? sumjson[aQuarter[i] + 'Plan'] : data[j][aQuarter[i] + 'Plan'];
        }
        aData.push(json);
    }
    //console.log(aData);
    return aData;
}

按季度系统对值进行求和
