javascript - 如何在 reactjs 中的数组数据中排列数组？

Question

我在里面有一个数组，在里面有一些多个数组，我试图在数组中排列那个数组，但我不知道哪里出了问题？那么如何正确设置数组内部数组呢？以下 arrayData 可用。

const arrayData = [
  form_id: 1,
  countTotal: 100,
  formName: 'Application Form',
  questions: [
    0: [
      questionName: 'what is your name ?',
      note: 'give firstname middlename and lastname also..',
      required: true,
      answer: 'my name is John dao',
      sequence: 0,
      questionType: 'long text',
      options: [],
    ]
    1: [
      questionName: 'select your gender ?',
      note: '',
      required: true,
      answer: 'Male',
      sequence: 1,
      questionType: 'Single Selector',
      options: [
        0: {
          option_id: 1,
          value: 'Male',
          sequence: 0,
          is_selected: true,
        },
        1: {
          option_id: 2,
          value: 'female',
          sequence: 1,
          is_selected: false,
        },
        2: {
          option_id: 3,
          value: 'Other',
          sequence: 2,
          is_selected: false,
        },
      ],
    ]
  ]
]

应该是这样的:

const arrayData = [
     form_id : 1,
     countTotal: 100,
     formName: 'Application Form',
     questions: [
                 [
                   questionName => 'what is your name ?',
                   note => 'give firstname middlename and lastname also..',
                   required => true,
                   answer => 'my name is khan, but i am not terrorist',
                   sequence => 0,
                   questionType => 'long text',
                   options => [], 
                 ],
                 [
                   questionName => 'select your gender ?',
                   note => '',
                   required => true,
                   answer => 'Male',
                   sequence => 1,
                   questionType => 'Single Selector',
                   options => [
                       { option_id: 1,
                         value: 'Male',
                         sequence: 0,
                         is_selected: true,
                       },
                       { option_id: 2,
                         value: 'female',
                         sequence: 1,
                         is_selected: false,
                       },
                       { option_id: 3,
                         value: 'Other',
                         sequence: 2,
                         is_selected: false,
                       },
                   ], 
                 ]
                ]
   ]

您不应该手动提供索引，因为它已经自动注册了。

array = ['data index 0','data index 1','data index 2'];

此外，您还可以使用此方法注册自己的索引:

array = [index1 => 'data index 1', index2 => 'data index 2'];
