跟官方代码一模一样

import Taro from '@tarojs/taro' import { View } from '@tarojs/components' import { AtIndexes, AtSearchBar } from 'taro-ui' import mockData, { CityItem } from './mock-data' import './index.scss'

interface IndexesState { value: string }

export default class Index extends Taro.Component<{}, IndexesState> { public config: Taro.PageConfig = { navigationBarTitleText: 'Taro UI' }

public constructor () { super(...arguments) this.state = { value: '' } }

public componentDidMount (): void { console.log(this.scrollIntoView) // this.scrollIntoView && this.scrollIntoView('top', 0) }

private scrollIntoView (key: string): void { console.log('不需要实际实现', key) }

private onClick (item: CityItem): void { console.log(item) }

private handleActionClick (): void { if (!this.state.value) { return } this.setState({ value: '' }) this.scrollIntoView && this.scrollIntoView(this.state.value.toUpperCase()) }

private handleChange (value: string): void { this.setState({ value }) }

public render (): JSX.Element { return (

{/* 基础用法 */} { this.scrollIntoView = fn }} > 用户自定义内容

} }
