我试图在使用tsx文件的React中使用模块 React Bootstrap Typeahead (original和type版本)。
我使用以下版本:
"@types/react-bootstrap-typeahead": "3.4.5"
"react-bootstrap-typeahead": "3.4.3"
我构建了以下 SimpleAsyncExample 类,无论用户键入什么,都试图始终返回相同的结果来测试组件,但响应有所延迟...
import * as React from 'react';
import {AsyncTypeahead, ClearButton, Token} from 'react-bootstrap-typeahead';
interface State {
capital: string;
name: string;
population: number;
region: string;
setValue: (value: State) => void;
}
const options: State[] = [
{ name: 'Alabama', population: 4780127, capital: 'Montgomery', region: 'South', setValue: () => {} },
{ name: 'Alaska', population: 710249, capital: 'Juneau', region: 'West', setValue: () => {} },
{ name: 'Arizona', population: 6392307, capital: 'Phoenix', region: 'West', setValue: () => {} },
{ name: 'Arkansas', population: 2915958, capital: 'Little Rock', region: 'South', setValue: () => {} },
{ name: 'California', population: 37254503, capital: 'Sacramento', region: 'West', setValue: () => {} },
{ name: 'Colorado', population: 5029324, capital: 'Denver', region: 'West', setValue: () => {} },
];
type propTypes = {};
type defaultProps = {
isLoading: boolean,
options: State[]
};
export default class SimpleAsyncExample extends React.Component<propTypes, defaultProps> {
state = {
isLoading: false,
options: []
};
render() {
return (
<div>
<AsyncTypeahead
{...this.state}
id="typeahead"
delay={800}
emptyLabel="No se encontraron resultados"
ignoreDiacritics={true}
minLength={3}
onSearch={this.onSearch}
placeholder="Insert text to search"
promptText="Searching"
searchText="Searching"
renderMenuItemChildren={(selectedItem: State, props) => {
return <Token
active
disabled={false}
tabIndex={5}
href="https://test.com"
onRemove={() => console.log(props.text)}>
{selectedItem.name}<ClearButton onClick={() => {}} />
</Token>;
}}
/>
</div>
);
}
onSearch = (query: string) => {
this.setState({isLoading: true});
setTimeout(() => {
this.setState({isLoading: false, options,});
}, 2000);
}
}
我还配置了css import ...(如文档所示)
import 'react-bootstrap-typeahead/css/Typeahead.css';
import 'react-bootstrap-typeahead/css/Typeahead-bs4.css';
此应用程序无法正常运行,不建议任何结果。
问题是,在测试或示例中,没有涉及AsyncTypeahead组件,并且我没有找到任何示例,因此,如果有人有解决方案,或者其他与Bootstrap 4和React( Typescript)或使用该库的工作示例,将不胜感激。
答案 0 :(得分:0)
您需要指定正确的labelKey
字段。默认情况下,该值为“标签”,但是在您的情况下,选项中没有“标签”字段,因此过滤器将失败。将labelKey
设置为“名称”可解决此问题:
<AsyncTypeahead
{...this.state}
id="typeahead"
delay={800}
emptyLabel="No se encontraron resultados"
ignoreDiacritics={true}
labelKey="name" // <---------- You're missing this
minLength={3}
onSearch={this.onSearch}
placeholder="Insert text to search"
promptText="Searching"
searchText="Searching"
/>
请注意,输入文本仍将过滤返回的结果,因此输入“ cal”将显示“ California”,但输入“ sdfgsdfg”将返回空结果集。
最后,库没有公开ClearButton
组件,因此在呈现菜单项时您会看到语法错误。
