javascript - Object.keys 及其值的数组循环

Question

我试图显示一个数组循环，其中有一个日期及其值。我能够循环数组的 Objects.keys 但内部循环需要单独显示键数组。这是一个简单数组的任务，但我无法弄清楚。 以下是我的代码。

var arr = {
    '2016-03-06' : ['1', '2','3','4','5'],          // 6th march 2016
    '2016-03-07' : ['6','7','8','9','10','11'],     // 7th march 2016
    '2016-03-08' : ['2','3','4','5'],           // 8th march 2016
    '2016-03-09' : ['6','7','8','9','10','11'],     // 9th march 2016
    '2016-03-10' : ['1', '2','3'],          // 10th march 2016
    '2016-03-11' : ['6','7','8','9','10','11'],     // 11th march 2016
};

var a=0;
var b=0;
ab = Object.keys(arr).length;
bc = Object.keys(arr)[b].length;
console.log(ab);
console.log(bc);

for(a=0; a < ab; a++){
    $('.result .array').append('<li data-date="'+Object.keys(arr)[a]+'">'+ Object.keys(arr)[a] + '</li>');
    for(b=0; b < Object.keys(arr).length; b++){
        $('.result .array').append('<li data-date='+ Object.keys(arr)[a]  +'>1</li>');
    }
}

我相信您正在寻找这样的输出:

var arr = {
    '2016-03-06' : ['1', '2','3','4','5'],          // 6th march 2016
    '2016-03-07' : ['6','7','8','9','10','11'],     // 7th march 2016
    '2016-03-08' : ['2','3','4','5'],           // 8th march 2016
    '2016-03-09' : ['6','7','8','9','10','11'],     // 9th march 2016
    '2016-03-10' : ['1', '2','3'],          // 10th march 2016
    '2016-03-11' : ['6','7','8','9','10','11'],     // 11th march 2016
};

for (var key in arr) {
    
  $('.result .array').append('<li data-date="'+key+'">'+ key + '</li>');

  var associatedData = arr[key];
  if($.isArray(associatedData)){
    for (var i = 0; i < associatedData.length; i++) {
      $('.result .array').append('<li data-date='+ associatedData[i]  +'>'+associatedData[i]+'</li>');
    }
  }
}
