我有这种搜索方法,我想在搜索后重定向用户。问题是它什么也没做,我不知道为什么。this.props.history 已定义,但对象“history”的“location”属性似乎没有根据我在 push 方法的参数('./connexion')中输入的内容发生相应变化...... URL 没有也不改变。搜索方法是绑定的,我用来export default withRouter(SearchBar);
通过道具访问历史记录。知道我在其他文件中使用完全相同的东西(this.props.history.push() 和 withRouter)并且它工作正常......我使用"react-router-dom": "^4.1.1"
browserHistory。
search(event) {
if (this.state.location === null) {
this.setState({ geosuggestId: 'geosuggest-input-alert' });
} else if (this.state.subjects.length === 0) {
this.setState({ matieresButtonId: 'matieres-button-alert' });
} else {
console.log(this.props.parent);
if (this.props.parent === 'Homepage') {
console.log(this.props.history);
this.props.history.push('/connexion');
}
}
}
