我试图改变这一点我找取请求的网站时,我点击按钮的应用程序组件接下来,通过其他网站阵营获取请求
<FilterableProductTable getSite={ this.state.active ? '/get_platfo
rms' : '/get_features' } />
,但它不工作,就说明只是旧的信息。我认为这是一些异步问题
export class FilterableProductTable extends React.Component {
constructor(props) {
super(props);
this.state = {
posts: []
};
}
fetch() {
axios.get(this.props.getSite)
.then(res => {
this.setState({
posts: res.data.functionality
});
});
}
componentDidMount() {
this.fetch();
setTimeout(function(){this.fetch();} , 5000);
}
render() {
return (
<div>
<ProductTable products={this.state.posts} />
</div>
);
}
}
export class App extends React.Component {
constructor(props){
super(props);
this.state= {active: true};
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState(prevState => ({
active: !prevState.active
}));
}
render() {
return (
<div>
<FilterableProductTable getSite={ this.state.active ? '/get_platforms' : '/get_features' } />
<a className={ this.state.active ? 'button' : 'hidden' } onClick={this.handleClick}><span>Next</span></a>
</div>
);
}
}
