我有一個這樣的陣列：
const faces= [
[[128516], "grinning face with smiling eyes", "20201001"],
[[128512], "grinning face", "20201001"],
[[128578], "slightly smiling face", "20201001"],
[[128579], "upside-down face", "20201001"],
[[128521], "winking face", "20201001"]
]
我想使用 Java 或 JavaScript 將其轉換為這樣的格式化 JSON，雖然不同，但兩者都很好：
[
{
"id": 128516,
"name": "grinning face with smiling eyes",
"date": "20201001"
},
{
"id": 128512,
"name": "grinning face",
"date": "20201001"
}
]
任何幫助表示贊賞。

你可以使用reduce：
const faces = [
[
[128516], "grinning face with smiling eyes", "20201001"
],
[
[128512], "grinning face", "20201001"
],
[
[128578], "slightly smiling face", "20201001"
],
[
[128579], "upside-down face", "20201001"
],
[
[128521], "winking face", "20201001"
]
]
const result = faces.reduce((result, value) => {
result.push({
id: value[0][0],
name: value[1],
date: value[2]
})
return result
}, [])
console.log(result)uj5u.com熱心網友回復：
使用陣列的“映射”功能的簡單單行代碼。
const faces= [
[[128516], "grinning face with smiling eyes", "20201001"],
[[128512], "grinning face", "20201001"],
[[128578], "slightly smiling face", "20201001"],
[[128579], "upside-down face", "20201001"],
[[128521], "winking face", "20201001"]
];
let newObj = [];
faces.map(eachObj => {
const obj = {
id: eachObj[0][0],
name: eachObj[1],
date: eachObj[2]
};
newObj.push(obj);
});
console.log('New Obj ==>', newObj);uj5u.com熱心網友回復：
你可以這樣做：
const faces= [
[[128516], "grinning face with smiling eyes", "20201001"],
[[128512], "grinning face", "20201001"],
[[128578], "slightly smiling face", "20201001"],
[[128579], "upside-down face", "20201001"],
[[128521], "winking face", "20201001"]
]
const formatedFaces = faces.reduce((acc, item)=> {
const obj ={
id: item[0][0],
name: item[1],
date: item[2]
};
acc.push(obj);
return acc;
}, []);
console.log(JSON.stringify(formatedFaces))uj5u.com熱心網友回復：
你可以 map
const faces= [
[[128516], "grinning face with smiling eyes", "20201001"],
[[128512], "grinning face", "20201001"],
[[128578], "slightly smiling face", "20201001"],
[[128579], "upside-down face", "20201001"],
[[128521], "winking face", "20201001"]
]
let result = faces.map(([ [id], name, date ]) => ({ id, name, date }))
