How to implement menu permission control using react
This article mainly introduces the method of implementing menu permission control in react. The editor thinks it is quite good. Now I will share it with you and give it as a reference. Let’s follow the editor and take a look.
Usually the company’s backend management system requires permission control, that is, users with different roles see different menus, as shown below:
Below, such a backend management system (scaffolding) is implemented through react. Function introduction:
1. The menu items at the top are dynamically generated based on the user's role.
2. Side test menu items are dynamically generated based on the selected top menu.
Go directly to the code:
Routing configuration:
export default (
<Route path="/" component={App}>
<IndexRoute component={EmployeeList}/>
<Route path="/employee" component={Employee}>
<IndexRoute component={EmployeeList}/>
<Route path="/employee/list" component={EmployeeList}/>
<Route path="/employee/detail/:id" component={EmployeeDetail}/>
</Route>
<Route path="/goods" component={Goods}>
<IndexRoute component={GoodsList}/>
<Route path="/goods/list" component={GoodsList}/>
<Route path="/goods/detail/:id" component={GoodsDetail}/>
</Route>
</Route>
)The top menu item becomes a separate component:
// 动态数据
import React, { Component } from 'react'
import { Link } from 'react-router' // 引入Link处理导航跳转
import { connect } from 'react-redux'
import { fetchPostsIfNeeded, updateSubMenuWhenClick } from '../actions/count'
import { Menu } from 'antd';
class TopMenu extends Component {
constructor(props){
super(props);
this.handleMenuClick = this.handleMenuClick.bind(this);
}
handleMenuClick(e){
// console.log(e.item.props['data-menukey']);
const { updateSubMenuWhenClick } = this.props
updateSubMenuWhenClick(true, e.item.props['data-menukey'])
}
componentWillMount() {
}
componentDidMount() {
const { fetchPostsIfNeeded } = this.props
fetchPostsIfNeeded()
}
render() {
const { menuList, fetchPostsIfNeeded } = this.props
if(menuList.length != 0) {
fetchPostsIfNeeded(true, menuList[0].key)
}
return (
<Menu
theme="dark"
mode="horizontal"
defaultSelectedKeys={['0']}
style={{ lineHeight: '64px' }}
onClick={this.handleMenuClick}
>
{
menuList.map((e, index) =>
<Menu.Item key={index} data-menukey={e.key} >
<Link to={{ pathname: e.url }} >{e.name}</Link>
</Menu.Item>
)
}
</Menu>
)
}
}
const getList = state => {
return {
menuList: state.update.menuList
}
}
export default connect(
getList,
{ fetchPostsIfNeeded, updateSubMenuWhenClick }
)(TopMenu)In the render function, if it is dynamically generated The data length of the top menu is not 0, and the side menu items are dynamically generated based on the key of the top menu.
const { menuList, fetchPostsIfNeeded } = this.props
if(menuList.length != 0) {
fetchPostsIfNeeded(true, menuList[0].key)
}The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
