我收到此错误:
./src/components/Playing.jsx
第15行:“ aaa”未定义为no-undef
在我的Playing.jsx中:
import React, { Component } from 'react'
console.log(aaa);
从我的Token.jsx
import { connect } from 'react-redux'
imports { Playing } from '../components/Playing'
const mapStateToProps = state => ({
aaa: "asdf"
})
export default connect(mapStateToProps)(Playing)
最佳答案
您将无法仅在文件中的任何地方console.log()
;它必须在Playing
组件的某些功能之内;而且也只能通过props
使用,例如
class Playing extends React.Component {
componentDidMount() {
console.log(this.props.aaa);
}
render() {
return <span>Playing</span>;
}
}
