我有一个看起来像这样的对象数组：
[
{
"group": {
"name": "Software Developers",
"desc":"some desc"
},
"name": "devs 1",
"file": "f1.csv"
},
{
"group": {
"name": "Software Developers",
"desc":"some desc"
},
"name": "devs 2",
"file": "f2.csv"
},
{
"group": {
"name": "Ceos",
"desc":"some desc"
},
"name": "ceos 1",
"file": "f3.csv"
},
{
"group": {
"name": "Ceos",
"desc":"some desc"
},
"name": "ceos 2",
"file": "f4.csv"
}
]
使用lodash如何将这个json数组转换为如下形式：
[
{
"group": {
"name": "Software Developers",
"desc":"some desc"
},
lists: [{ "name": "devs 1", "file": "f1.csv" }, { "name": "devs 2", "file": "f2.csv" }]
},
{
"group": {
"name": "Ceos",
"desc":"some desc"
},
lists: [{ "name": "ceos 1", "file": "f3.csv" }, { "name": "ceos 2", "file": "f4.csv" }]
}
]我尝试了各种解决方案，但没有任何运气。
_.groupBy()的group.name，然后_.map()以所希望的结构：
const data = [{"group":{"name":"Software Developers","desc":"some desc"},"name":"devs 1","file":"f1.csv"},{"group":{"name":"Software Developers","desc":"some desc"},"name":"devs 2","file":"f2.csv"},{"group":{"name":"Ceos","desc":"some desc"},"name":"ceos 1","file":"f3.csv"},{"group":{"name":"Ceos","desc":"some desc"},"name":"ceos 2","file":"f4.csv"}];
const result = _.flow([
(arr) => _.groupBy(arr, 'group.name'),
(groups) => _.map(groups, (g) => ({
..._.head(g).group,
lists: _.map(g, o => _.pick(o, ['name', 'file']))
}))
])(data);
console.log(result);<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>本文收集自互联网，转载请注明来源。
