我对图表高度有疑问。在Home.js中,当我在底部声明export default HomePage
时,该图表将显示在屏幕上,但是当我声明export default withAuthorization (authCondition) (HomePage)
时,该图表将不再显示。我认为withAuthorization.js文件存在问题,但我仍然没有发现错误。我想知道如何解决。谢谢大家!
这是Home.js
代码:
import React, { Component } from 'react';
import withAuthorization from './withAuthorization';
import HomeLiveChart from './HomeLiveChart';
class HomePage extends Component {
render() {
return (
<div id="wrapper">
<div className="main-content container">
<div className="row small-spacing">
<HomeLiveChart />
</div>
</div>
</div>
);
}
}
const authCondition = (authUser) => !!authUser;
export default withAuthorization(authCondition)(HomePage);
//export default HomePage;
这是Chart.js
代码:
import React, { Component } from 'react';
class HomeLiveChart extends Component {
render() {
return (
<div>
<div className="col-xs-6">
<div className="box-content">
<div id="random-temp"></div>
</div>
</div>
<div className="col-xs-6">
<div className="box-content">
<div id="random-humi"></div>
</div>
</div>
</div>
)
}
}
export default HomeLiveChart;
这是withAuthorization.js
代码:
import React from 'react';
import { withRouter } from 'react-router-dom';
import AuthUserContext from './AuthUserContext';
import { firebase } from '../firebase';
import * as routes from '../constants/routes';
const withAuthorization = (authCondition) => (Component) => {
class WithAuthorization extends React.Component {
componentDidMount() {
firebase.auth.onAuthStateChanged(authUser => {
if (!authCondition(authUser)) {
this.props.history.push(routes.SIGN_IN);
}
});
}
render() {
return (
<AuthUserContext.Consumer>
{authUser => authUser ? <Component /> : null}
</AuthUserContext.Consumer>
);
}
}
return withRouter(WithAuthorization);
}
export default withAuthorization;
这是AuthUserContext.js
代码:
import React from 'react';
const AuthUserContext = React.createContext(null);
export default AuthUserContext;
在Home.js中声明export default withAuthorization (authCondition) (HomePage)
时屏幕不显示图表
