小问题。我有收藏品
var allnames = {
'names':
[
{ 'name': [ {'surname': 'moe'}, {'nickname': 'moose' } ] },
{ 'name': [ {'surname':'larry'}, {'nickname': 'lark' } ] }
]
};
并希望访问/获取每个'surname'
和'nickname'
。
我尝试了不同的选项而没有任何运气(例如_.each
/ _.map
)。
有没有人在这方面有经验?

此代码段会将您拥有的结构转换为更易于使用的结构:
var names = _.map( allnames.names, function(n){
// n is an array with each object having one property; either a surname or a nickname
return _.reduce(n.name, function(memo,part){ return _.extend(memo,part); }, {})
});
这里的名称将是一个对象数组,每个对象都有一个姓氏和一个昵称:
[ { surname: 'moe', nickname: 'moose' }, { surname: 'larry', nickname: 'lark' } ]
一旦你有了这个结构,很容易操纵那个数组来提取你想要的东西,例如得到所有的姓氏:
var surnames = _.pluck(names, 'surname');
var nicknames = _.pluck(names, 'nickname');

I eventually found a solution, which covers what I was striving at
var allnames = {
'names':
[
{ 'name': [ {'surname': 'moe'}, {'nickname': 'moose' } ] },
{ 'name': [ {'surname': 'larry'}, {'nickname': 'lark' } ] }
]
};
var surnames = [];
var nicknames = [];
function nameproc(myobj)
{
if ( myobj.surname )
{
surnames.push(myobj.surname);
return myobj.surname
}
if( myobj.nickname)
{
nicknames.push(myobj.nickname);
return myobj.nickname;
}
}
_.each(allnames.names, function(myobj)
{
_.each(myobj, function(nameobj)
{
var nameobj = _.each(nameobj,nameproc);
});
});
// Print out the surnames and nicknames
console.log(surnames);
console.log(nicknames);
