reactjs - ESLint 必须使用解构状态赋值

Question

我收到以下行的 ESlint 错误 this.state.items.map(item => (

错误是必须使用解构状态赋值

{
            this.state.items.map(item => (
              <div key={item}>
                {
                item.links.map(thing => (
                  <NavLink
                    key={thing.link.id}
                    exact
                    to={thing.link.url}
                  >
                    {thing.link.text}
                  </NavLink>
                ))
                }
              </div>
            ))
          }

我正在使用“eslint-config-airbnb”

此外，这是我的 componentDidMount 函数(如果相关的话)

componentDidMount() {
  fetch('./data/data_arr.js')
  .then(results => results.json())
  .then(results => this.setState({ items: results }));
}

任何尝试和理解这一点的帮助都会很棒。谢谢

这就是所谓的:

Enforce consistent usage of destructuring assignment of props, state, and context (react/destructuring-assignment)

更多详细信息请参见:destructuring-assignment

为了使该警告/错误消失，您可以这样做:

      ...
      const { items }= this.state;
      ...
      {
        items.map(item => (
          <div key={item}>
            {
            item.links.map(thing => (
              <NavLink
                key={thing.link.id}
                exact
                to={thing.link.url}
              >
                {thing.link.text}
              </NavLink>
            ))
            }
          </div>
        ))
      }
