javascript - 将对象转换为具有 lodash 中父子关系的数组

Question

这可以用 lodash 或任何其他 javascript/typescript 方式实现吗

var obj = {
    a: [ {id:1},{id:2},{id:3}]
    b: [ {id:4},{id:5},{id:6}]
    c: [ {id:7},{id:8},{id:9}]
}
// transform to 
var arr = [
{title:a, items:[{id:1},{id:2},{id:3}]},
{title:b, items: [ {id:4},{id:5},{id:6}]},
{title:c, items: [ id:7},{id:8},{id:9}]}
]

Answer 1

您可以使用Object.keys来实现:

var obj = {
    a: [ {id:1},{id:2},{id:3}],
    b: [ {id:4},{id:5},{id:6}],
    c: [ {id:7},{id:8},{id:9}]
}

var result = Object.keys(obj).map(function(key) {
  return { title: key, items: obj[key] }
})

console.log(result);
