要求:点击账号或密码,自动将焦点转到相关的表单控件(input)上。 问题:功能可以使用,但是会有报错。 解决办法:react中label标签没有for属性,用htmlFor代替for属性 demo的代码: 报错 修改后的代码

例如,上面的 MyInput 组件,我们可以修改代码为: 代码语言:javascript 复制 import{forwardRef,useImperativeHandle,useRef}from'react'type MyInputProps=React.InputHTMLAttributes<HTMLInputElement>&{label:string}functionMyInput(props:MyInputProps,ref:any){const{label,...other}=propsconstinputRef=useRef<any>(...
input = input} /> </label> <input type="submit" value="Submit" /> </form> ); } } 总结: 页面中所有输入类的DOM如果是现用现取的称为非受控组件,而通过setState将输入的值维护到了state中,需要时再从state中取出,这里的数据就受到了state的控制,称为受控组件。
