reacthooks使⽤ref操作form⼦组件
⽗组件
import React, { useState, useRef, useEffect, forwardRef } from 'react'
import ModelForm from './ModelFormCopy'
这样写 const ForwardEditInfo = forwardRef(ModelForm))  如果组件中有 connect 要使⽤ forwardRef 就会报错
Warning: forwardRef requires a render function but received a `memo` component. Instead of forwardRef(memo(...)), use memo(forwardRef(...)).改⽤下⾯这个
注意：！！这⾥不在Component上使⽤ref  换个属性名不然会导致覆盖
const ForwardEditInfo = (forwardRef((props, ref) => <ModelForm {...props} refInstance={ref} />))
const DrawerEdit = (props)=>{
let addRef = useRef()
const submit=()=>{
// 获取到了
let params = addRef.current.p()
}
return(
<ForwardEditInfo
ref={addRef}
searchMobile={searchMobile}
reacthooks理解
initialValues={currentItem}
></ForwardEditInfo>
)
}
⼦组件
const ModelForm=(props)=>{
const editRef = useRef()
fInstance, () => ({
p: FieldsValue
}))
return (
<div ref={editRef}>
</div>
)
}
