我的数组，存储在名为data的变量中

代码语言：javascript
复制
var data = [
  {
     "name": "username",
     "value": null,
     "schema": {
        "version": 1,
        "name": "form.text"
     }
  },      
  {
     "name": "password",
     "value": null,
     "schema": {
        "version": 1,
        "name": "form.text"
     }
  },
  {
     "name": "gender",
     "value": "other",
     "schema": {
        "version": 1,
        "value_type": "string",

           },
           {
              "value": "other",
              "label": "Other"

           {
              "value": "2",
              "label": "USA"

        ]
     }
  },
  {
     "name": "hobby",
     "value": "['book', 'movie']",
     "schema": {
        "version": 1,
        "value_type": "string",
        "name": "form.text",
        "choices": [
           {
              "value": "travel",
              "label": "Traveling"
           },
           {
              "value": "book",
              "label": "Reading"
           },
           {
              "value": "movie",
              "label": "Watching Movie"
           }
        ]
     }
  },
  {
     "name": "privacy",
     "value": null,

     "value": null,
     "schema": {
        "version": 1,
        "name": "form.text"
     }
  }
]

我的对象，存储在名为formObj的变量中

代码语言：javascript
复制
var formObj = {


username: {
    value: null,
    type: 'text',
    label: 'Username',
    placeholder: 'Enter username',
    position: 'left',
    block: 'firstRow',
    order: 1,
    additionalClass: 'user'
  },
  password: {
    value: null,
    type: 'password',
    label: 'Password',
    placeholder: 'enter password',
    position: 'left',
    block: 'firstRow',
    order: 2
  },
  country: {
    value: '3',
    type: 'select',
    label: 'Where are you form?',
    //defaultText: 'Choose here',
    position: 'right',
    block: 'firstRow',
    order: 2,
    option: [{
        value: '1',
        label: 'Australia'
      },
      {
        value: '2',
        label: 'USA'
      },
      {
        value: '3',
        label: 'UK'
      }
    ]
  },
  gender: {
    value: 'female',
    type: 'select',
    label: 'Gender',
    defaultText: null,
    position: 'right',
    block: 'firstRow',
    order: 1,
    option: [{
        value: 'male',
        label: 'Male'
      },
      {
        value: 'female',
        label: 'Female'
      },
      {
        value: 'other',
        label: 'Other',
        additionalAttr: 'disabled'
      }
    ]
  },
  decision: {
    value: 'not sure',
    type: 'radio',
    label: 'Have you enjoyed it?',
    position: 'left',
    block: 'secondRow',
    order: 1,
    option: [{
        value: 'yes',
        label: 'Yes',
        additionalAttr: 'disabled'
      },
      {
        value: 'no',
        label: 'No',
      },
      {
        value: 'not sure',
        label: 'I am not sure',
      }
    ]
  },
  message: {
    value: null,
    type: 'textarea',
    label: 'Message',
    placeholder: 'type your message',
    position: 'right',
    block: 'secondRow',
    order: 2,
  },
  vehicle: {
    value: 'car',
    type: 'checkbox',
    label: 'Preferred vehicles',
    position: 'left',
    block: 'secondRow',
    order: 2,
    option: [{
        value: 'car',
        label: 'I like car'
      },
      {
        value: 'bike',
        label: 'I prefer bike'
      },
      {
        value: 'boat',
        label: 'Boat is my favorit'
      }
    ]
  },
  hobby: {
    value: ['book', 'movie'],
    type: 'checkbox',
    label: 'Hobbies',
    position: 'left',
    block: 'secondRow',
    order: 3,
    option: [{
        value: 'travel',
        label: 'Traveling'
      },
      {
        value: 'book',
        label: 'Reading'
      },
      {
        value: 'movie',
        label: 'Watching movie'
      }
    ]
  },
  privacy: {
    value: null,
    type: 'checkbox',
    label: 'Privacy',
    position: 'right',
    block: 'secondRow',
    order: 3,
    option: [{
        value: 'agree',
        label: 'I agree'
      }
    ]
  },
  email: {
    value: null,
    type: 'text',
    label: 'Email',
    placeholder: 'Enter email',
    position: 'right',
    block: 'secondRow',
    order: 1,
    additionalAttr: 'disabled',
    additionalClass: 'emailbox custom'
  }
}

因此，在data(数组)中有8 objects，在formObj(object)中有10 objects。

我的目标是将来自data的name与formObj进行匹配，并仅使用匹配的对象创建新对象。新对象的所有数组都应该来自data( value )。简而言之，创建一个类似于/来自formObj的newObj。newObj将不包含不在data(数组)中的对象。

我试着在这里写下这个概念，但不知道如何继续：

代码语言：javascript
复制
for (var i = 0; i < data.length; i++) {
   if (data[i].name === formObj[key]) {
      newObj = formObj;   // take only those from formObj which exist in data
      newObj[option] = data[schema][choices];  // take the option from choices
      newObj[value] = data[value];  // take the value from value
   }
}

因此，newObj将为：

代码语言：javascript
复制
var newObj = {


username: {
    value: null,
    type: 'text',
    label: 'Username',
    placeholder: 'Enter username',
    position: 'left',
    block: 'firstRow',
    order: 1,
    additionalClass: 'user'
  },
  password: {
    value: null,
    type: 'password',
    label: 'Password',
    placeholder: 'enter password',
    position: 'left',
    block: 'firstRow',
    order: 2
  },
  country: {
    value: '3',
    type: 'select',
    label: 'Where are you form?',
    //defaultText: 'Choose here',
    position: 'right',

        value: '1',
        label: 'Australia'
      },
      {
        value: '2',
        label: 'USA'
