如何在Lodash中将数组转换为对象？

Question

I have:

{
     dis:{["String1","String2","String3"]},
     par:"pony"
}

And I want to turn it into this:

[
    { name: 'String1', value: "pony" },
    { name: 'String2', value: "pony" },
    { name: 'String3', value: "pony" }
]

Answer 1

If you change to valid js data you can do this with reduce()

 var obj = { dis: ["String1", "String2", "String3"], par: "pony" } var result = obj.dis.reduce(function(r, e) { r.push({name: e, value: obj.par}); return r; }, []); console.log(result) 

Answer 2

You can do it easily, but beware you have double parentheses (mustaches and square bracket).

var 
    data = {
        dis: ["String1","String2","String3"],
        par: "pony"
    }, 

  result = [];

for (var index in data.dis)
    result.push({ name: data.dis[index], value: data.par}

you can find the fiddle here .

You can do it using Array.protoype.map :

 var obj = { dis:["String1","String2","String3"], par:"pony" }; var arrOfObj = obj.dis.map(function(name) { return { name: name, value: obj.par } }); console.log(arrOfObj) 

Or lodash's _.map :

 var obj = { dis:["String1","String2","String3"], par:"pony" }; var arrOfObj = _.map(obj.dis, function(name) { return { name: name, value: obj.par } }); console.log(arrOfObj);
