我试图从我的渲染视图重构以下代码:
<Button href="#" active={!this.state.singleJourney} onClick={this.handleButtonChange.bind(this,false)} >Retour</Button>
到绑定在构造函数内的版本。原因是渲染视图中的绑定会给我带来性能问题，尤其是在低端手机上。
我已经创建了以下代码，但我经常得到以下错误(很多)。看起来应用程序进入了一个循环:
Warning: setState(...): Cannot update during an existing state transition (such as within `render` or another component's constructor). Render methods should be a pure function of props and state; constructor side-effects are an anti-pattern, but can be moved to `componentWillMount`.
下面是我使用的代码:
var React = require('react');
var ButtonGroup = require('react-bootstrap/lib/ButtonGroup');
var Button = require('react-bootstrap/lib/Button');
var Form = require('react-bootstrap/lib/Form');
var FormGroup = require('react-bootstrap/lib/FormGroup');
var Well = require('react-bootstrap/lib/Well');
export default class Search extends React.Component {
constructor() {
super();
this.state = {
singleJourney: false
};
this.handleButtonChange = this.handleButtonChange.bind(this);
}
handleButtonChange(value) {
this.setState({
singleJourney: value
});
}
render() {
return (
<Form>
<Well style={wellStyle}>
<FormGroup className="text-center">
<ButtonGroup>
<Button href="#" active={!this.state.singleJourney} onClick={this.handleButtonChange(false)} >Retour</Button>
<Button href="#" active={this.state.singleJourney} onClick={this.handleButtonChange(true)} >Single Journey</Button>
</ButtonGroup>
</FormGroup>
</Well>
</Form>
);
}
}
module.exports = Search;
