JavaScript | JSON对象按值合并和排序

Question

I have the following json abjects, and I like to merge them into one object and the short the sub-objects based on 'minute' value. Is that posible with JavaScript ?

[Object, Object, Object]
    0: Object
        Live: "188585"
        Minute: "17"
        Player: "Player A"
        Team: "188564"
        __proto__: Object
    1: Object
        Live: "188585"
        Minute: "26"
        Player: "Player B"
        Team: "188564"
        __proto__: Object
    2: Object
        Live: "188585"
        Minute: "77"
        Player: "Player A"
        Team: "188564"
        __proto__: Object
[Object, Object]
    0: Object
        Live: "188585"
        Minute: "31"
        Player: "Player C"
        Team: "188558"
        __proto__: Object
    1: Object
        Live: "188585"
        Minute: "41"
        Player: "Player D"
        Team: "188558"
        __proto__: Object

the result I like to be like that:

[Object, Object, Object, Object, Object]
    0: Object
        Live: "188585"
        Minute: "17"
        Player: "Player A"
        Team: "188564"
        __proto__: Object
    1: Object
        Live: "188585"
        Minute: "26"
        Player: "Player B"
        Team: "188564"
        __proto__: Object
    2: Object
        Live: "188585"
        Minute: "31"
        Player: "Player C"
        Team: "188558"
        __proto__: Object
    3: Object
        Live: "188585"
        Minute: "41"
        Player: "Player D"
        Team: "188558"
        __proto__: Object
    4: Object
        Live: "188585"
        Minute: "77"
        Player: "Player A"
        Team: "188564"
        __proto__: Object

Answer 1

If your two arrays are already sorted by minute, you can use the "classical" merge algorithms. If not, you can concat your arrays and sort the result using Array.sort (with a specific compare function).

Edit: here is an example:

1. If arrays are not sorted:

    var result = array1.concat(array2); result.sort(function(item1, item2) { return item1.Minute - item2.Minute; }); 

2. If arrays are sorted, here is a simple merge function:

    function merge(array1, array2) { var results = []; var i = 0, j = 0; while (i < array1.length && j < array2.length) { if (array1[i].Minute <= array2[j].Minute) { results.push(array1[i]; i++; } else { results.push(array2[j]; j++; } } while (i < array1.length) { results.push(array1[i]; i++; } while (j < array2.length) { results.push(array2[j]; j++; } return results; } 

Answer 2

More then objects they seems arrays of objects. If it's that the case, you can use Array.concat to concatenate, and Array.sort to sort.

Something like:

// assuming `aba` is the first array, `cd` the second
var result = aba.concat(cd);

result.sort(function(a, b) {
    return a.Minute - b.Minute // implicit conversion in number
});

console.log(result);
