1、根据list值生成静态菜单代码

SiderMenu.vue

<template>
  <div>
    <a-button type="primary" style="margin-bottom: 16px"> LOGO </a-button>
    <a-menu
      :default-selected-keys="['1']"
      :default-open-keys="['2']"
      mode="inline"
      :theme="theme"
      :inline-collapsed="collapsed"
    >
      <template v-for="item in list">
        <a-menu-item v-if="!item.children" :key="item.key">
          <a-icon type="pie-chart" />
          <span>{{ item.title }}</span>
        </a-menu-item>
        <sub-menu v-else :key="item.key + '1'" :menu-info="item" />
      </template>
    </a-menu>
  </div>
</template>

<script>
import { mapState } from "vuex";
import { Menu } from "ant-design-vue";
const SubMenu = {
  template: `
      <a-sub-menu :key="menuInfo.key" v-bind="$props" v-on="$listeners">
        <span slot="title">
          <a-icon type="mail" /><span>{{ menuInfo.title }}</span>
        </span>
        <template v-for="item in menuInfo.children">
          <a-menu-item v-if="!item.children" :key="item.key">
            <a-icon type="pie-chart" />
            <span>{{ item.title }}</span>
          </a-menu-item>
          <sub-menu v-else :key="item.key" :menu-info="item" />
        </template>
      </a-sub-menu>
    `,
  name: "SubMenu",
  // must add isSubMenu: true
  isSubMenu: true,
  props: {
    ...Menu.SubMenu.props,
    // Cannot overlap with properties within Menu.SubMenu.props
    menuInfo: {
      type: Object,
      default: () => ({}),
    },
  },
};
export default {
  components: {
    "sub-menu": SubMenu,
  },
  props: {
    theme: {
      type: String,
      default: "dark",
    },
  },
  data() {
    return {
      list: [
        {
          key: "1",
          title: "Option 1",
        },
        {
          key: "2",
          title: "Navigation 2",
          children: [
            {
              key: "2.1",
              title: "Navigation 2.1",
              children: [{ key: "2.1.1", title: "Option 2.1.1" }],
            },
          ],
        },
        {
          key: "3",
          title: "Navigation 3",
          children: [
            {
              key: "3.1",
              title: "Navigation 3.1",
            },
          ],
        },
      ],
    };
  },
  computed: {
    ...mapState(["collapsed"]),
  },
  mounted() {},
  methods: {},
};
</script>
<style lang="less" scoped></style>

vue 报错 You are using the runtime-only build of Vue where the template compiler is not available.

vue.config.js

module.exports = {
  runtimeCompiler: true
}

2、根据路由生成动态菜单

SiderMenu.vue

<template>
  <div>
    <a-button type="primary" style="margin-bottom: 16px"> LOGO </a-button>
    <a-menu
      :default-selected-keys="[$route.path]"
      :default-open-keys="['/'+ $route.path.split('/')[1]]"
      mode="inline"
      :theme="theme"
      :inline-collapsed="collapsed"
      @click="onClick"
    >
      <template v-for="item in menu">
        <a-menu-item v-if="!item.children" :key="item.path">
          <a-icon :type="item.meta.icon" />
          <span>{{ item.meta.title }}</span>
        </a-menu-item>
        <sub-menu v-else :key="item.path " :menu-info="item" />
      </template>
    </a-menu>
  </div>
</template>

<script>
import { mapState } from "vuex";
import { Menu } from "ant-design-vue";
const SubMenu = {
  template: `
      <a-sub-menu :key="menuInfo.key" v-bind="$props" v-on="$listeners">
        <span slot="title">
          <a-icon :type="menuInfo.meta.icon" /><span>{{ menuInfo.meta.title }}</span>
        </span>
        <template v-for="item in menuInfo.children">
          <a-menu-item v-if="!item.children" :key="item.path">
            <span>{{ item.meta.title }}</span>
          </a-menu-item>
          <sub-menu v-else :key="item.key" :menu-info="item" />
        </template>
      </a-sub-menu>
    `,
  name: "SubMenu",
  // must add isSubMenu: true
  isSubMenu: true,
  props: {
    ...Menu.SubMenu.props,
    // Cannot overlap with properties within Menu.SubMenu.props
    menuInfo: {
      type: Object,
      default: () => ({}),
    },
  },
};
export default {
  components: {
    "sub-menu": SubMenu,
  },
  props: {
    theme: {
      type: String,
      default: "dark",
    },
  },
  data() {
    return {
      menu: [],
    };
  },
  computed: {
    ...mapState(["collapsed"]),
  },
  mounted() {
    // 根据路由获取菜单数据
    this.getMenuData(this.$router.options.routes, this.menu);
  },
  methods: {
    getMenuData(routes, arr) {
      routes.forEach((el) => {
        if (!el.hiden) {
          arr.push(el);
          if (el.children) {
            // 这里使用一个变量接收子数组作为递归的数据源
            // 将item.children置空用来接收不隐藏的数据
            let a = el.children;
            el.children = [];
            this.getMenuData(a, el.children);
          }
        }
      });
      return arr;
    },
    onClick(item) {
      this.$router.push(item.key);
    },
  },
};
</script>
<style lang="less" scoped></style>
