javascript - JQuery 将项目添加到我的 JSON

Question

我正在用phonegap制作一个小游戏，这是我的本地存储/记分板代码。我在这个记分牌中保留分数和时间，我做了几个例子，它们出现了，但不是我应该添加的例子？

var localData = function(){

var _local = [
    {
        "score": 1,
        "datum": "di 25 jan 2016"
    },
    {
        "score": 5,
        "datum": "di 26 jan 2016"
    },
    {
        "score": 9,
        "datum": "di 27 jan 2016"
    },
    {
        "score": 10,
        "datum": "di 28 jan 2016"
    }
];


var _setLocalStorage = function () {
    console.log("Score word bewaard");
    console.log(_local);
    localStorage.setItem('LocalData', JSON.stringify(_local));
    _scoreList();
};

var _scoreList = function () {
    var DatumVanNu =  new Date().toDateString();
    console.log(DatumVanNu + ' _local = ' + _local.length);
    console.log(_local);
    $('#tbodyid').empty();
    for (var i = 0; i < _local.length; i++){
        console.log(_local[i].datum)

        var item = '<tr> <td>' + _local[i].score + '</td> <td>'+ _local[i].datum +'</td> </tr>';
         $('tbody').append(item);

    }
    console.log('gedaan')
};

var init = function () {
    console.log("score word geopent");
    _local = [];
    var local_str = localStorage.getItem('LocalData');
    if(local_str !== null){
        _local = JSON.parse(local_str);
    }
    console.log(_local);
    _scoreList();

};
var addScore = function (score) {
    console.log("Score wordt toegevoegd");
    var datum = new Date();
    _local.score = score;
    _local.datum = datum;
    _scoreList();

};

return {
    init:   init,
    addScore:  addScore
};

}()

您似乎正在向 _local 列表添加属性，而不是在函数 addScore 中向其中添加项目

尝试更改为以下内容

var addScore = function (score) {
    _local.push({score: score, datum : new Date()});
    _scoreList();
};

而不是

  _local = []
  ... 
  _local.score = .. 
  _local.datanum = ... 

请告诉我这是否有效。
