javascript - 在 JavaScript 中从两个数组生成对象数组

Question

我有 2 个数组:

var arrToObjContent = ["DAYOFWEEK","ITEM","QTY","DATEOFPURCHASE","CITY"]
var dayOfWeek="["SUN","MON","TUE","WED","THU","FRI","SAT"]

我一直在尝试使用上面的两个数组创建一个对象数组，如下所示:

{
"DAYOFWEEK":"SUN"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
},    {
"DAYOFWEEK":"MON"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
},{
"DAYOFWEEK":"TUE"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
},{
"DAYOFWEEK":"WED"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
},{
"DAYOFWEEK":"THU"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
},{
"DAYOFWEEK":"FRI"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
},{
"DAYOFWEEK":"SAT"
"ITEM":"",
"QTY":"",
"DATEOFPURCHASE":"",
"CITY":""
}

是否有一个 jQuery/JavaScript 内置函数，我可以将两个数组传递给并获得如上所示的输出？

其实没那么难，看这里:

var arrToObjContent = ["DAYOFWEEK","ITEM","QTY","DATEOFPURCHASE","CITY"],
    dayOfWeek = ["SUN","MON","TUE","WED","THU","FRI","SAT"],
    i=0,
    z,
    arrToObjLength = arrToObjContent.length,
    dayOfWeekLength = dayOfWeek.length,
    jsonObj = {},
    newObj,
    key,
    value;

for(;i<dayOfWeekLength;i++){
    newObj = {};
    for(z=0;z<arrToObjLength;z++){
        key = arrToObjContent[z];

        if(key === "DAYOFWEEK") {
            value = dayOfWeek[i];
        }   
        else {
            value = "";
        }
        newObj[key] = value;
    }
    jsonObj[i] = newObj;
}

console.table(jsonObj);
