我正在尝试在react中呈现以下数据。
const fakeData = {
201907: {
15: [{
yearMonthKey: '201907',
dayKey: '15',
startDate: '2019-07-15 00:00:00+0900',
title: 'testProgrma',
time: '04:29 ~ 04:29',
imageUrl: [faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false)],
firstCome: 10
},
{
yearMonthKey: '201907',
dayKey: '15',
startDate: '2019-07-15 00:00:00+0900',
title: 'testProgrma123132',
time: '04:29 ~ 04:29',
imageUrl: [faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false)],
firstCome: 10
}],
16: [{
yearMonthKey: '201907',
dayKey: '16',
startDate: '2019-07-15 00:00:00+0900',
title: 'testProgrma',
time: '04:29 ~ 04:29',
imageUrl: [faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false)],
firstCome: 10
}]
},
201908: {
17: [{
yearMonthKey: '201908',
dayKey: '17',
startDate: '2019-08-15 00:00:00+0900',
title: 'testProgrma',
time: '04:29 ~ 04:29',
imageUrl: [faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false), faker.image.imageUrl(612, 477, undefined, true, false)],
firstCome: 10
}]
}
}
fakeData包含两个大数组(201907,201908),每个对象,另一个对象嵌套在内部(15、16、17)。每个嵌套对象都将数组作为值。
但这是问题所在。
组件必须呈现如下。
201907
ㅣ
- 15
ㅣ
- title:'testProgrma',
- title:'testProgrma123132'
- 16
ㅣ
- title: 'testProgrma'
201908
ㅣ
- 17
ㅣ
- title: 'testProgrma'
它是深层嵌套的,并根据yearMonthKey和dayKey进行绑定。

反应不会让对象渲染。因此,在循环之前尝试构建数组。
let newArray = []
for(let j in fakeData){
for(let i in j){
newArray.push(i)
}
}
console.log(newArray)
然后使用.map()渲染newArray
