我有一个项目列表(作业),当选择一个项目(作业)时,正在打开一个新场景。我希望所选项目的ID从包含列表的场景传递到另一个场景,其中包含有关所选项目(作业)的详细信息,而不使用Redux。
路由器
import React from 'react';
import { Scene, Router } from 'react-native-router-flux';
import JobsList from './components/JobsList';
import Job from './components/Job';
const RouterComponent = () => {
return (
<Router>
<Scene key="jobs" component={JobsList} initial />
<Scene key="Job" component={Job} title="Test" />
</Router>
);
};
export default RouterComponent;
职位列表
import React, { Component } from 'react';
export default class JobsList extends Component {
render() {
return (
<TouchableOpacity onPress={() => { Actions.Job({ jobId: jobId }) }}>
...
</TouchableOpacity>
);
}
}
工作
import React, { Component } from 'react';
export default class Job extends Component {
constructor() {
super();
this.state = {
job: {}
};
axios.get(
// PROBLEM: this.props.jobId is empty
`http://api.tidyme.dev:5000/${this.props.jobId}.json`,
{
headers: { Authorization: 'Token token=123' }
}
).then(response => this.setState({
job: response.data
}));
}
render() {
return (
<Text>{this.state.job.customer.firstName}</Text>
);
}
}

如果要在构造函数中访问super(props)
,则应调用this.props
。
constructor(props) {
super(props);
console.log(this.props);
}

最佳做法是将组件定义为纯函数:
const Job = ({ job, JobId}) => {
return (
<Text>{job.customer.firstName}</Text>
);
}
otherFunctions() {
...
}
