我有一个JSON数组,其中的对象包含标题和主题标记数组。我想使其成为一个简单的json文件,并具有所有处于第一级的值。
这就是我所拥有的:
options.UseSqlite
到目前为止,我尝试了array.map和reduce函数,还尝试了lodash.results(lodash.find(data,“ title”)),然后将其与列名映射。它没有用。
[
{
"title":"mca",
"result":[
{
"sub1":1,
"sub2":2
},
{
"sub1":1.23,
"sub2":1.25
},
{
"sub1":3.4,
"sub2":2.3
}
]
},
{
"title":"bca",
"result":[
{
"sub1":1.1,
"sub2":2.8
},
{
"sub1":1.15,
"sub2":1.18
},
{
"sub1":1.2,
"sub2":1.9
}
]
}
]
预期输出:
const arr = [
{
"title":"mca",
"result":[
{
"sub1":1,
"sub2":2
},
{
"sub1":1.23,
"sub2":1.25
},
{
"sub1":3.4,
"sub2":2.3
}
]
}
];
const test = [].concat(...arr.map((item) => item.results.map((results) => Object.assign({}, item, { results }))));
console.log(test);
