我们可以通过将子组件包装成一个前向引用React 提供的函数,它将处理这个委托。这个函数应该传输发送的 props 并允许组件上有一个额外的 props,即我们的“ref”。这是代码: How to use forwardRef in React? 使用命令式句柄 好吧,看起来,我们在上一节中取得的成就对于即使是复杂的情况也足够了。不过,有时您可能...
可以考虑使用React.forwardRef(props, ref) 去传递一层ref // demoimportReactfrom'react'constTargetComponent=React.forwardRef((props, ref) =>())exportdefaultclassCompextendsReact.Component{constructor() {super()this.ref=React.createRef() }componentDidMount() {this.ref.current.value='ref get input'}...

React 引用传递 Forwarding Refs 引用传递(Ref forwading)是一种通过组件向子组件自动传递引用ref的技术。对于应用者的大多数组件来说没什么作用。但是对于有些重复使用的组件,可能有用。例如某些input组件,需要控制其focus,本来是可以使用ref来控制,但是因为该input已被包裹在组件中,这时就需要使用Ref forward来透过组件...
