vue根据权限动态渲染按钮、组件等的函数式组件实现

const checkAuth = (authName) => {
    let authMap = ['admin', 'superAdmin', 'admin-1', 'landq'] // 根据实际项目需求配置
    return authMap.includes(authName);
}
export default checkAuth;

<!-- 函数式组件 -->
<script>
import checkAuthorized from './auth';
export default {
    functional: true, // 函数式组件
    props: {
        // 接收参数
        authName: {
            type: String,
            required: true,
            default: ''
        }
    },
    render(h, context) {
        let { props, scopedSlots } = context;
        return checkAuthorized(props.authName)
            ? scopedSlots.default({
                  name: props.authName
              })
            : null;
    }
};
</script>

、、、
import Authorized from '@/components/authorized'; // 权限
 
Vue.config.productionTip = false;
Vue.component('Authorized', Authorized);
 
new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");

<!-- authorized -->
<template>
    <div class="authorized">
        <Authorized authName="admin">
            <el-button type="primary" slot-scope="data">{{
                data.name
            }}</el-button>
        </Authorized>
    </div>
</template>

<script>
export default {
    components: {},
    data() {
        return {};
    },
    created() {},
    //生命周期 - 挂载完成（可以访问DOM元素）
    mounted() {},
    computed: {},
    //方法集合
    methods: {}
};
</script>

<style lang='scss' scoped>
//@import url(); 引入公共css类
</style>
