javascript - 如何修复对象 JSON 的错误数组？

标签 javascript jquery json

我无法在 JSON 中创建对象数组。当我单击出现在 JSON 上的保存按钮 (#btnSave) 时，显示如下。我想要的是我创建的一个表单，特别是使用 TAG4 名称创建的表单，该名称具有 div 类名称“toAdd”，可以按照我的需要在下面进行分组。那么如何解决呢？

我的数据:

{
  "TAG1_ID": "1",
  "TAG2_ID": "2",
  "TAG3_ID": "3",
  "TAG4_NAME": [
    "Me",
    "You"
  ],
  "TAG4_AGE": [
    "20",
    "22",
    "17",
    "4"
  ],
  "TAG4_JOB": [
    "Police",
    "Fireman",
    "Student",
    "Baby"
  ]
}

我想这样创建:

{
  "TAG1_ID": "1",
  "TAG2_ID": "2",
  "TAG3_ID": "3",
  "temp": [
    {
      "TAG4_NAME": "Me",
      "detail_temp": [
        {
          "TAG4_AGE": "20",
          "TAG4_JOB": "Police"
        },
        {
          "TAG4_AGE": "22",
          "TAG4_JOB": "Fireman"
        }
      ],
    },
    {
      "TAG4_NAME": "You",
      "detail_temp": [
        {
          "TAG4_AGE": "17",
          "TAG4_JOB": "Student"
        },
        {
          "TAG4_AGE": "4",
          "TAG4_JOB": "Baby"
        }
      ],
    }
  ]
}

Javascript:

function saveForm(){
          var array = []; 
          var object = {};
          var serialArray = $('.ltktForm').serializeArray();
          /* var serialArray = $('.ltktForm'); 
          var data = JSON.stringify(serialArray.serializeArray()); */
          $.each(serialArray, function(){
           if(object[this.name]){
            if(!object[this.name].push){
                object[this.name] = [object[this.name]];
            }
            object[this.name].push(this.value || '');
           }else{
               object[this.name] = this.value || '';
           }
          });
          return object;
    } 

    $('#btnSave').on('click', function () {
            var data = saveForm();
            console.log(JSON.stringify(data));atas));

        });

我的表单:

<form class="form form-horizontal myForm" novalidate method="POST">
        <div class="tabNavigator">
            <ul class="nav nav-tabs" role="tablist">

                <li role="presentation" class="active">
                    <a id="id2" href="#idTwo" class="tab_trigger" aria-controls="home" role="tab" data-toggle="tab">ID_2</a>

最佳答案

你必须像这样手动构造数组:

$(function() {
  var toAdd = '<fieldset>' + '<legend>Temp</legend>' + '<div class="form-group">' + '<label class="col-sm-2 control-label">Input Name</label>' + '<div class="col-sm-9">' + '<input class="form-control" type="text" name="TAG4_NAME" />' + '</div>' + '</div>' + '<div class="form-group ">' + '<label class="col-sm-2 control-label">Input Age</label>' + '<div class="col-sm-9">' + '<input class="form-control" type="text" name="TAG4_AGE" />' + '</div>' + '</div>' + '<div class="form-group ">' + '<label class="col-sm-2 control-label">Input Job</label>' + '<div class="col-sm-9">' + '<input class="form-control" type="text" name="TAG4_JOB" />' + '</div>' + '</div>' + '</fieldset>';

  $('.addForm').on('click', function() {
    $(this).parent().find('div.toAdd').append(toAdd);
  });

  $('#btnSave').on('click', function() {
    var result = {};

    //Get the value of tag1, tag2, tag3
    result.TAG1_ID = $("input[name='TAG1_ID']").val();
    result.TAG2_ID = $("input[name='TAG2_ID']").val();
    result.TAG3_ID = $("input[name='TAG3_ID']").val();
    //You can add more input tags here <--
    

    var temp = {};
    //Loop thru tag4 divs
    //Loop thru fieldsets and get each value
    $(".toAdd fieldset").each(function() {
      var name = $(this).find("input[name='TAG4_NAME']").val();
      var age = $(this).find("input[name='TAG4_AGE']").val();
      var job = $(this).find("input[name='TAG4_JOB']").val();

      temp[name] = temp[name] || {
        TAG4_NAME: name,
        detail_temp: []
      }
      temp[name]["detail_temp"].push({
        TAG4_AGE: age,
        TAG4_JOB: job
      });
    });

    result.temp = Object.values(temp).map(v => v);

    console.log(result);

  });
});
