這是我的 JSON 對象：{"id": 2,"full_name": "Karan Kumar","user_skills": [ { "skill_id": 1, "skill": { "skill_name": "Angular 8" } }, { "skill_id": 3, "skill": { "skill_name": "Java Spring" } }],"resource_allocateds": [ { "project_id": 1, "end_date": "2019-06-20", "project": { "project_name": "Inventory System" } }, { "project_id": 2, "end_date": "2020-01-15", "project": { "project_name": "Hospital Management System" } } ]}我想從上面的 JSON 中選擇某些屬性，并且我希望它是這樣的：{ "id": 1, "full_name": "Karan Kumar", "skills": [{ "skill_id": 1, "skill_name": "Angular 8" }, { "skill_id": 3, "skill_name": "Java Spring" }], "resource_allocateds": [{ "project_id": 1, "end_date": "2019-06-20", "project_name": "Inventory System" }, { "project_id": 2, "end_date": "2020-01-15", "project_name": "Hospital Management System" }]}我試過使用 Lodash's partialRight，但它似乎不適用于可迭代對象，也嘗試過 flatMap，但沒有用。如果有人幫助我解決這個問題，那就太好了。提前致謝！

你可以使用 vanilla javascript 而不是 Lodash 來做到這一點。尋找像 map/reduce/filter 這樣的 ES6 方法。例子 ：
const input = {
"id": 2,
"full_name": "Karan Kumar",
"user_skills": [
{
"skill_id": 1,
"skill": {
"skill_name": "Angular 8"
}
},
{
"skill_id": 3,
"skill": {
"skill_name": "Java Spring"
}
}
],
"resource_allocateds": [
{
"project_id": 1,
"end_date": "2019-06-20",
"project": {
"project_name": "Inventory System"
}
},
{
"project_id": 2,
"end_date": "2020-01-15",
"project": {
"project_name": "Hospital Management System"
}
}
]
};
const { id, full_name, user_skills, resource_allocateds } = input;
const output = {
id,
full_name,
skills: user_skills.map(item => ({
skill_id: item.skill_id,
skill_name: item.skill.skill_name
})),
resource_allocateds: resource_allocateds.map(item => ({
project_id: item.project_id,
end_date: item.end_date,
project_name: item.project.project_name
})),
}

您可以使用toArrayand mapValueslike 如下所示：
const jsonData = {
"id": 2,
"full_name": "Karan Kumar",
"user_skills": [
{
"skill_id": 1,
"skill": {
"skill_name": "Angular 8"
}
},
{
"skill_id": 3,
"skill": {
"skill_name": "Java Spring"
}
}
],
"resource_allocateds": [
{
"project_id": 1,
"end_date": "2019-06-20",
"project": {
"project_name": "Inventory System"
}
},
{
"project_id": 2,
"end_date": "2020-01-15",
"project": {
"project_name": "Hospital Management System"
}
}
]
};
const transformedJson = {...jsonData};
transformedJson.user_skills = _.toArray(_.mapValues(transformedJson.user_skills, ({ skill_id, skill }) => {
return {
skill_id,
skill_name: skill.skill_name
};
}));
transformedJson.resource_allocateds = _.toArray(_.mapValues(transformedJson.resource_allocateds, ({ project_id, project }) => {
return {
project_id,
project_name: project.project_name
};
}));
document.getElementById('jsonResults').innerHTML = JSON.stringify(transformedJson, null, 2);
