Vue权限指令控制权限详解

import permission from './permission'
import Vue from 'vue'
Vue.directive('permission', permission)

import store from '@/store'

	const { value } = binding
	const roles = await store.getters && store.getters.permission
	if( value && value instanceof Array) {
		if( value.length > 0) {
			const permissionRoles = value
			const hasPermission = roles.some(role => {
				return permissionRoles.includes(role)
			})
			if(!hasPermission) {
				el.parentNode && el.parentNode.removeChild(el)
			}
		}
	}else {
		throw new Error('需要以数组的形式传角色')
	}
}
export default {
	inserted(el, binding) {
		checkPermission(el, binding)
	},
	update(el, binding) {
		checkPermission(el, binding)
	}
}

<el-button v-permission="['add']">权限按钮</el-button>
