保存TextInput数组的状态 - React Native

Question

我正在从API中获取多个TextInputs，并在我的屏幕上显示它们。因此，如何将用户输入状态保存到全局对象。这样的东西：

    state = {
    foundtextfields: []
   }

在这里，我将这些获取的TextInput推向Founttextfields []数组：

var foundTextFields = [];
    foundTextFields.push(<TextInput>{keyvalue_to_json.inputFields[i].placeholderText}</TextInput>)

我正在此列表中显示文本输入：

return (
    <View>
      {foundtextfields}
    </View>
)

编辑：我想循环遍历数组的状态，然后从该ex中提取键。"钥匙"（签名）并匹配下面的JSON Body属性" signedbyfullname"。

  postToBmp = (obje) => {
var userArray = [];
for (i = 0; i < this.myInputFields.myTextFields.length; i++) {
       userArray.push(this.myInputFields.myTextFields[i])
       console.log("this is the title of al inputFields:",   this.myInputFields.myTextFields[i].key)
}
fetch('URL', {
  method: 'POST',
  headers: {
    Accept: 'application/json',
    'Content-Type': 'application/json',
    'Connection': 'Keep-Alive',
  },
  credentials: 'include',
  body: JSON.stringify({
    from: '[e-mail]',
    to: ['<[e-mail]>'],
    signedByFullName: '',
    signedByCPRNumber: '',
    otherCompanyName: '',
    otherCompanyCVRNumber: ''
  })
})

}

Answer 1

要存储可以使用值沿侧面foundtextfields创建数组的值，并且每次更改文本时，都将其设置为其他数组的索引

喜欢：

    foundTextFields.push(
      <TextInput 
         onChangeText={(text) =>{
            let inputValues=this.state.inputValues;
            inputValues[i]=text;
            this.setState({inputValues})
         }}>
        {keyvalue_to_json.inputFields[i].placeholderText}
      </TextInput>)

或

foundTextFields.push(
      <TextInput 
         onChangeText={(text) =>{
            keyvalue_to_json=this.state.keyvalue_to_json
            keyvalue_to_json.inputFields[i].inputValues=text;
            this.setState({keyvalue_to_json})
         }}>
        {keyvalue_to_json.inputFields[i].placeholderText}
      </TextInput>)
