Question

我想知道如何添加此

{ post_id: 1, text: "text", creation: "date" }

到＆＃34;帖子＆＃34;在像这样的数组

 var posts = [

    {
        post_id: 5, 
        text: "text", 
        creation: "date"
    },
    {
        group: "favPosts",
        posts: [
                    { post_id: 2, text: "text", creation: "date" }, 
                    { post_id: 7, text: "text", creation: "date" }
               ]
    },
    {
        post_id: 8, 
        text: "text", 
        creation: "date"
    }
]

我已经尝试了一百次搜索，但我似乎无法找到适合我的情况的答案，我一直试图插入像切片和推送这样的命令，但我可以＆＃39; t似乎做对了，我还是javascript的初学者。

PS：我已经找到了解决方案，但我认为它不是非常有效的，并且＃34 ;;

addToGroup("favPosts");

function addToGroup(group) {

    for(id in posts) {

        if(posts[id].group == group){

            posts[id].posts.push({ post_id: 10, text: "did it", creation: "date" });

            console.log(posts[id]);
        }
    }
}

这应该是推动，我不明白为什么这不会起作用。这是一个例子，我只是使用angular来轻松地在HTML中显示，而不是你正在做的事情：http://plnkr.co/edit/PBCYxfjMqV3jzggMHJZ7?p=preview

var people = [
    {
        name: "Joe",
        surname: "surname"
    },
    { 
        group: "name",
        people: [{ name: "name", surname: "surname" }, { name: "name", surname: "surname"     }]
    },
    {
        name: "James",
        surname: "surname"
    }
];

var person = { name: "Jennifer", surname: "surname" };

people.push(person);

将数据推送到没有索引的数组
