好客租房156-封装顶部导航栏组件(3功能处理withRouter)

import React from 'react'
import { NavBar } from 'antd-mobile'
// 导入 withRouter 高阶组件
import { withRouter } from 'react-router-dom'
import "./index.scss"
 function NavHeader({children,history,onLeftClick}) {
 // 默认点击行为
 const defaultHandler = () => history.go(-1)
 return (
   <NavBar
     className="navbar"
     mode="light"
     icon={<i className="iconfont icon-back" />}
     onLeftClick={onLeftClick || defaultHandler}
   >
     {children}
   </NavBar>
 )
}
//函数的返回值也是一个组件
export default withRouter(NavHeader)
