将数组中的字符串转换为对象

Question

I am receiving an array of strings from a server in the following format:

var fruitsStrings = ["apple", "banana", "orange" ];

Is it possible to convert this into an array of objects, like below?

var fruitsObjects = [
    {
        fruit: "apple"
    },
    {
        fruit: "banana"
    },
    {
        fruit: "orange"
    }
];

All the object properties will be the same. Happy to use pure JavaScript or jQuery. I've tried using jquery.extend but as this adds unique IDs before each value it's not really fit for my purpose.

Thank you.

Answer 1

var fruitsStrings = ["apple", "banana", "orange" ];
var fruitsObjects = [];

fruitsStrings.forEach(function (item) {
    fruitsObjects.push({ fruit: item });
});

Answer 2

you can use .map

var fruitsStrings = ["apple", "banana", "orange" ];
var fruitsObjects  = fruitsStrings.map(function( val, i ) {
  return {fruit:val};
});
document.write(JSON.stringify(fruitsObjects));

 var fruitsStrings = ["apple", "banana", "orange" ]; var fruitsObjects = fruitsStrings.map(function( val, i ) { return {fruit:val}; }); document.write(JSON.stringify(fruitsObjects));

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Answer 3

Try this:

var fruitsStrings = ["apple", "banana", "orange" ];
var fruitsObjects = [];

$.map( fruitsStrings, function( val, i ) {
  fruitsObjects.push({ fruits: val });
});

Answer 4

A simple Array.prototype.map will do:

 var fruitsStrings = ["apple", "banana", "orange"], fruitsArray = fruitsStrings.map(function (a) { return { fruit: a } }); document.write('<pre>' + JSON.stringify(fruitsArray, 0, 4) + '</pre>');

Answer 5

You could also use this function where you can specify the key.

function toObjects(key,arr) {
  var objects = [];
  for (var i = 0; i < arr.length; ++i){
    var obj = {};
    obj[key] = arr[i];
    objects[i] = obj;
  }
  return objects;
}

var fruitsStrings = ["apple", "banana", "orange" ];
toObjects('fruit',fruitsStrings);
// [{fruit: "apple"},{fruit: "banana"},{fruit: "orange"}]

Answer 6

Try this:

var fruitsStrings = ["apple", "banana", "orange" ];
var fruitsObjects = [];

fruitsStrings.map(function(v,i){
    fruitsObjects.push({'fruit':v});
});

console.log(fruitsObjects);
