Javascript推入两个for循环覆盖数组

我想循环一个对象数组和另一个数组来创建一个新数组

This.wholeWeek = [{test: "1"}, {test2: "2"}, {test3: "3"}]

This.courtData = [1, 2, 3]

因此，我希望得到：

[{test: "1", court: 1}, {test: "1", court: 2}, {test: "1", court: 3}, {test2: "2", court: 1}, {test2: "2", court: 2}, {test2: "2", court: 3}, {test3: "3", court: 1}, {test3: "3", court: 2}, {test3: "3", court: 3}]

代码：

非常感谢您的帮助！谢谢大家!

你能试试这个代码吗：

let arr = [{test: "1"}, {test2: "2"}, {test3: "3"}];
let arr_1 = [1, 2, 3];
let result = [];

for (let i = 0; i < arr.length; i++) {
    for (let j = 0; j < arr_1.length; j++) {
            let obj = JSON.parse(JSON.stringify(arr[i])); // copy of object
            obj.court = arr_1[j];
            result.push(obj);
    }
}

让arr=[{test:1}，{test2:2}，{test3:3}]；
设arr_1=[1,2,3]；
让结果=[]；
for（设i=0；i

你应该复制一个对象。

你得到了这个结果，因为你在第一个数组中不断地更改对象。你需要在修改它之前复制一个

这个。wholeWeek[i]

。啊，我的错。这可以删除，如果需要，因为它是一个大的重复！谢谢大家!！

[{test: "1", court: 3}, {test: "1", court: 3}, {test: "1", court: 3}, {test2: "2", court: 3}, {test2: "2", court: 3}, {test2: "2", court: 3}, {test3: "3", court: 3}, {test3: "3", court: 3}, {test3: "3", court: 3}]

let arr = [{test: "1"}, {test2: "2"}, {test3: "3"}];
let arr_1 = [1, 2, 3];
let result = [];

for (let i = 0; i < arr.length; i++) {
    for (let j = 0; j < arr_1.length; j++) {
            let obj = JSON.parse(JSON.stringify(arr[i])); // copy of object
            obj.court = arr_1[j];
            result.push(obj);
    }
}
