Question

我有一个名为SiteTechnologyForm

的组件

class SiteTechnologyForm extends React.Component {

  static propTypes = {
    name: PropTypes.string,
    site_technology_id_number: PropTypes.string,
    common_site: PropTypes.string,
    title: PropTypes.string,
    errors: PropTypes.string
  }

  constructor(props) {
    super(props);

    this.state = {
      logged_in: localStorage.getItem('token') ? true : false,
      name: props.name || '',
      site_technology_id_number: props.site_technology_id_number || '',
      common_site: props.common_site || '',
    };

    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
  }

  UNSAFE_componentWillMount() {
    if (!this.state.logged_in) {
      browserHistory.push("/accounts/login");
    }
  }

  handleChange(event) {
    if (event.target && event.target.name){
      this.setState({[event.target.name]: event.target.value});
    }
  }

  handleSubmit() {
    let payload = {
      "common_site": this.state.common_site,
      "name": this.state.name,
      "site_technology_id_number": this.state.site_technology_id_number
    };
    this.props.handleSubmit(payload)
  }

  render() {
    const {
      title,
      errors
    } = this.props;

    return !this.state.logged_in ? '' :
      <BaseForm title={title} handleSubmit={this.handleSubmit} errors={errors} data={this.state}>
        <CommonSiteAutocomplete
          label="CommonSite *"
          id="id_common_site"
          required={true}
          inputProps={{
            name: "common_site",
            onChange: this.handleChange,
            value: this.state.common_site,
            required: true
          }}
        />
        <CustomInput
          labelText="Name *"
          id="id_name"
          formControlProps={{
            fullWidth: true
          }}
          inputProps={{
            type: "text",
            onChange: this.handleChange,
            name: "name",
            value: this.state.name,
            required: true
          }}
        />
        <CustomInput
          labelText="Site Technology ID *"
          id="id_site_technology_id_number"
          formControlProps={{
            fullWidth: true
          }}
          inputProps={{
            type: "text",
            onChange: this.handleChange,
            name: "site_technology_id_number",
            value: this.state.site_technology_id_number,
            required: true
          }}
        />
      </BaseForm>
  }
}

ESlint抱怨道具验证缺少handleSubmit。

SiteTechnologyForm用于下面的其他组件，例如AddSiteTechnology：

class AddSiteTechnology extends React.Component {

  constructor(props) {
    super(props);

    this.state = {
      errors: ''
    };

    this.handleSubmit = this.handleSubmit.bind(this);
  }

  handleSubmit(data) {

    fetch(siteTechUrl, {
      headers: {
        'Content-Type': 'application/json',
        Authorization: `Token ${localStorage.getItem('token')}`
      },
      method: 'POST',
      body: JSON.stringify(data),
    })
      .then(response => {
        if (response.status >= 400) {
          return this.setState({errors: response.statusText});
        }
        browserHistory.push("/site_technologies/list");
      })
  }

  render() {
    return <SiteTechnologyForm title="Add Site Technology" handleSubmit={this.handleSubmit} errors={this.state.errors}/>
  }
}

我最初尝试使用

handleSubmit: PropTypes.function

但是当我尝试运行网页时，我在控制台中收到此错误

checkPropTypes.js：19警告：道具类型失败：SiteTechnologyForm：道具类型handleSubmit无效；它必须是一个函数，通常来自prop-types包，但已收到undefined。

如何通过handleSubmit未通过验证来解决这种情况？

Answer 1

根据ESLINT，您还需要为handleSubmit道具提供道具类型。函数类型由func而非function处理：

handleSubmit: PropTypes.func

Answer 2

您尚未在handleSubmit声明列表中定义propTypes类型，eslint找不到handleSubmit。

像这样将handleSubmit定义为function类型，我相信它总是必需的，所以也要添加isRequired。

static propTypes = {
  name: PropTypes.string,
  site_technology_id_number: PropTypes.string,
  common_site: PropTypes.string,
  title: PropTypes.string,
  errors: PropTypes.string,
  handleSubmit: PropTypes.func.isRequired
}
