Question

我有这个数据结构

[
    {photos: [{name:'abc'}]},
    {photos: [{name:'xyz'}]},
]

如何添加名称属性作为照片的兄弟像这样

[
    {photos: [{name:'abc'}], name:'abc'}
    {photos: [{name:'xyz'}], name: 'xyz'},
]

Answer 1

类似的东西：

    var src = [
        {photos: [{name:'abc'}]},
        {photos: [{name:'xyz'}]},
    ]

    var dest = src.map(function (item) {
        return { photos: item.photos, name : item.photos[0].name} 
    })

Answer 2

这样的东西？

x = [
    {photos: [{name:'abc'}]},
    {photos: [{name:'xyz'}]},
]

x[0].name = "abc"

console.log(x)

OP:- [
    {photos: [{name:'abc'}], name:'abc'}
    {photos: [{name:'xyz'}]},
]

由于这是一个例子，我只是发布了一种添加name属性的方法。这里发生的是因为x是json对象的数组，所以通过x [0]

向json对象添加属性很简单

获取属性值并将属性添加到新数组中
