Javascript ReactJS：更改字段的特征

我有一个表单，有三个字段

两个字段取决于第一个字段的选择。 如果第一个字段设置为true，那么其他两个字段必须禁用=false和required=true，否则相反

因此，我：

 constructor(props){
    super(props);
    this.state = {
      requiredData: false
    }
    this.handleChange = this.handleChange.bind(this)
  }

handleChange(selected){
    console.log('selected', selected)
    const { requiredData } = this.state
    this.setState({
      requiredData: selected
    })
    console.log('this.state',this.state)
  }


render()
{
 {
        name: 'SelfCertification.Contract',
        col: ["lg-6", 'md-6', 'sm-12'],
        label: "A Contratto",
        required: true,
        validate: FieldValidation.required,
        ..._common,
        CustomOnChange: selected => {
        handleChange: this.handleChange(selected)}
      },
      {
        name: 'SelfCertification.Contract.StartDate',
        col: ["lg-4", 'md-4', 'sm-12'],
        label: "Data Inizio",
        disabled: this.state.requiredData  ? false : true,
        required: this.state.requiredData  ? true : false,
        component: Fields.Text,
      },
      {
        name: 'SelfCertification.Contract.EndDate',
        col: ["lg-4", 'md-4', 'sm-12'],
        label: "Data Fine",
        disabled:  this.state.requiredData  ? false : true,
        required: this.state.requiredData  ? true : false,
        component: Fields.Text,
      },

//...

}

现在使用此代码，因此如果将其设置为选中的true（在

SelfCertification.Contract

中），则字段（

SelfCertification.Contract.StartDate，SelfCertification.Contract.EndDate

）正确

disable:false/required:true

但是如果我在字段中写入，

SelfCertification.Contract

的单选按钮就会消失。 而且，如果我再次更改我的第一个选择，字段不会返回到状态

disable:true/required:false

我该怎么办

我想要得到的：

Field1 (SelfCertification.Contract):
o Yes 
o No

Field2 (SelfCertification.Contract.StartDate or SelfCertification.Contract.EndDate)
disabled: true,
required: false.


Field1 (SelfCertification.Contract):
X Yes 
o No

Field2 (SelfCertification.Contract.StartDate or SelfCertification.Contract.EndDate)
disabled: false,
required: true.
 

Field1 (SelfCertification.Contract):
o Yes 
X No

Field2 (SelfCertification.Contract.StartDate or SelfCertification.Contract.EndDate)
disabled: true,
required: false.
