javascript中具有键值对的数组中的键值对

Question

I have an array like this:

var arrayTemp = [
{"0":["Z",59]},
{"1":["D",53]},
{"2":["6",26]},
{"3":["3",19]},
{"4":["Y",10]},
{"5":["H",7]},
{"6":["G",5]},
{"7":["2",5]}
];

I need an output similar to the below one,

var arrayTemp = [
{"Z":59},
{"D":53},
{"6":26},
{"3":19},
{"Y":10},
{"H":7},
{"G":5},
{"2":5}
];

How do I achieve this? I would like this to be achieved with the help of json, underscore or JavaScript.

Answer 1

Using Array.prototype.map() you could iterate trough each element of the original array and create the required objects, returning them as new elements in a new array.

var newArray = arrayTemp.map(function(e, index) { 
    var x = {};
    x[e[index][0]] = e[index][1];

    return x;
})

Answer 2

Something like this:

var newArray = arrayTemp.map(function(e) { 
    var index = Object.keys(e).shift(),
        innerElement = e[index],
        ret = {};

    ret[innerElement[0]] = innerElement[1];
    return ret;
})

JsFiddle to test.

Answer 3

With underscore:

var newArr = _.map(arrayTemp, function(item){
    for (var i in item){
       var o = {};
       o[item[i][0]] = item[i][1];
       return o;
    }
});

Although @François_Wahl's solution is the better one in my esteem using the native Array.prototype.map().
