1.父子组件传值需借助 中间ts文件
hook/context-manager.tsx
// 使用hook给父子组件共享数组
import { createContext } from "@tarojs/taro";
export default createContext({});
2.父组件
import TripContext from ‘../../hook/context-manager‘
import Trip_success from ‘../../components/trip_success/index‘
function Home() {
const [content, setContent] = useState({})
const [contentType, setContentType] = useState(false)
return (
<View>{contentType}
<TripContext.Provider value={{ content, urlName: ‘home‘,setContentType}}>
<Trip_success />
</TripContext.Provider>
</View>
)
}
import TripContext from ‘../../hook/context-manager‘
import Taro, { useContext, useEffect } from "@tarojs/taro";
function Trip_success() {
const { content, urlName, setContentType } = useContext(TripContext)
useEffect(() => {setContentType(true)})
console.log(‘获取父组件中值‘, content, urlName) }
Taro 中父组件传多个值到子组件, 不同页面传值， 子组件修改父组件值
