中断JSON对象并添加到表中

作者：携手相约幸福 | 2023-09-10 12:29
如何解决《中断JSON对象并添加到表中》经验，为你挑选了1个好方法。

我需要从JSON对象中检索sprintID和issue_name并将它们添加到表中.以下是我到目前为止所做的工作.

这是一些示例JSON.

var mock_data = {
  "criticalList": [{
    "issue_id": 9,
    "local_id": 0,
    "issue_name": "issue_01",
    "project_id": 0,
    "estimated_time": 5,
    "dependents": [10, 11],
    "localdependents": [],
    "critical": true
  }, {
    "issue_id": 11,
    "local_id": 0,
    "issue_name": "issue_03",
    "project_id": 0,
    "estimated_time": 5,
    "dependents": [15, 16, 14],
    "localdependents": [],
    "critical": true
  }, {
    "issue_id": 14,
    "local_id": 0,
    "issue_name": "issue_06",
    "project_id": 0,
    "estimated_time": 6,
    "dependents": [21],
    "localdependents": [],
    "critical": true
  }, {
    "issue_id": 21,
    "local_id": 0,
    "issue_name": "issue_12",
    "project_id": 0,
    "estimated_time": 4,
    "dependents": [29],
    "localdependents": [],
    "critical": true
  }, {
    "issue_id": 29,
    "local_id": 0,
    "issue_name": "issue_20",
    "project_id": 0,
    "estimated_time": 6,
    "dependents": [34],
    "localdependents": [],
    "critical": true
  }, {
    "issue_id": 34,
    "local_id": 0,
    "issue_name": "issue_25",

    }, {
      "issue_id": 39,
      "local_id": 0,
      "issue_name": "issue_30",
      "project_id": 0,
      "estimated_time": 4,
      "dependents": [37, 38],
      "localdependents": [],
      "critical": false,
      "sprintID": "2015-12-28_2015-12-31"
    }]
  }]
};

这是不起作用的循环.

$(mock_data.sprints).each(function(i, value) {
  $(sprints.value).each(function(j, val) {
    $('.list').append('' +
      '' + (i + 1) + '' +
      '' + val.sprintID + '' +
      '' + val.issue_name + '' +
      '');
  });
});

HTML是这样的,



1> 小智..：

问题是内部循环试图访问未定义的变量sprints.value.所有你需要做的纠正脚本,改sprints.value以value.issues在第二循环中的对象遍历的issues数组.

$(mock_data.sprints).each(function(i, value) {
    $(value.issues).each(function(j, val) {
        $('.list').append('' +
                          '' + (i + 1) + '' +
                          '' + val.sprintID + '' +
                          '' + val.issue_name + '' +
                          '');
    });
});


var mock_data = {sprints:[{issues:[{issue_name:'issue_01',sprintID:'2015-12-01_2015-12-04'},{issue_name:'issue_03',sprintID:'2015-12-01_2015-12-04'},{issue_name:'issue_02',sprintID:'2015-12-01_2015-12-04'},{issue_name:'issue_08',sprintID:'2015-12-01_2015-12-04'},{issue_name:'issue_07',sprintID:'2015-12-01_2015-12-04'},{issue_name:'issue_06',sprintID:'2015-12-01_2015-12-04'}]},{issues:[{issue_name:'issue_05',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_04',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_15',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_14',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_13',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_12',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_11',sprintID:'2015-12-07_2015-12-11'},{issue_name:'issue_10',sprintID:'2015-12-07_2015-12-11'}]},{issues:[{issue_name:'issue_09',sprintID:'2015-12-14_2015-12-18'},{issue_name:'issue_21',sprintID:'2015-12-14_2015-12-18'},{issue_name:'issue_20',sprintID:'2015-12-14_2015-12-18'},{issue_name:'issue_19',sprintID:'2015-12-14_2015-12-18'},{issue_name:'issue_18',sprintID:'2015-12-14_2015-12-18'},{issue_name:'issue_17',sprintID:'2015-12-14_2015-12-18'}]},{issues:[{issue_name:'issue_16',sprintID:'2015-12-21_2015-12-25'},{issue_name:'issue_25',sprintID:'2015-12-21_2015-12-25'},{issue_name:'issue_24',sprintID:'2015-12-21_2015-12-25'},{issue_name:'issue_23',sprintID:'2015-12-21_2015-12-25'}]},{issues:[{issue_name:'issue_22',sprintID:'2015-12-28_2015-12-31'},{issue_name:'issue_27',sprintID:'2015-12-28_2015-12-31'},{issue_name:'issue_26',sprintID:'2015-12-28_2015-12-31'},{issue_name:'issue_29',sprintID:'2015-12-28_2015-12-31'},{issue_name:'issue_28',sprintID:'2015-12-28_2015-12-31'},{issue_name:'issue_30',sprintID:'2015-12-28_2015-12-31'}]}]};

$(mock_data.sprints).each(function(i, value) {
  $(value.issues).each(function(j, val) {
    $('.list').append('' +
                      '' + (i + 1) + '' +
