在后臺管理系統(tǒng)中當(dāng)點(diǎn)擊某一按鈕時，頁面發(fā)生跳轉(zhuǎn)(路由發(fā)生跳轉(zhuǎn)，跳轉(zhuǎn)到與按鈕對應(yīng)的頁面)，在跳轉(zhuǎn)的同時在側(cè)邊欄中打開與之對應(yīng)模塊的菜單項(xiàng)

1.點(diǎn)擊按鈕跳轉(zhuǎn)到/pay/PayIndex頁面

2.在后臺管理系統(tǒng)中側(cè)邊欄使用的是element ui 中的NavMenu導(dǎo)航菜單組件，在后臺管理系統(tǒng) src/layout/components/Sidebar/index中代碼如下：

<template>
  <div
    :class="{ 'has-logo': showLogo }"
    :style="{
      backgroundColor:settings.sideTheme === 'theme-dark'? variables.menuBackground : variables.menuLightBackground,}">
    <logo v-if="showLogo" :collapse="isCollapse" />
    <el-scrollbar :class="settings.sideTheme" wrap-class="scrollbar-wrapper">
      <el-menu
        :default-active="activeMenu"
        :collapse="isCollapse"
        :background-color=" settings.sideTheme === 'theme-dark' ? variables.menuBackground : variables.menuLightBackground"
        :text-color="settings.sideTheme === 'theme-dark' ? variables.menuColor: variables.menuLightColor"
        :unique-opened="true"
        :active-text-color="settings.theme"
        :collapse-transition="false"
        mode="vertical"
        :default-openeds="openeds"
      >
        <sidebar-item
          v-for="(route, index) in sidebarRouters"
          :key="route.path + index"
          :item="route"
          :base-path="route.path"
        />
      </el-menu>
      <!-- :index="route.path" -->
    </el-scrollbar>
  </div>
</template>

<script>
import { mapGetters, mapState } from "vuex";
import Logo from "./Logo";
import SidebarItem from "./SidebarItem";
import variables from "@/assets/styles/variables.scss";

export default {
  components: { SidebarItem, Logo },
  data() {
    return {
      openeds: [],
    };
  },
  computed: {
    ...mapState(["settings"]),
    ...mapGetters(["sidebarRouters", "sidebar"]),
    activeMenu() {
      const route = this.$route;
      const { meta, path } = route;
      // if set path, the sidebar will highlight the path you set
      if (meta.activeMenu) {
        return meta.activeMenu;
      }
      return path;
    },
    showLogo() {
      return this.$store.state.settings.sidebarLogo;
    },
    variables() {
      return variables;
    },
    isCollapse() {
      return !this.sidebar.opened;
    },
  },
  //組件路由發(fā)生變化，打開與組件對應(yīng)模塊的菜單項(xiàng)
  watch: {
    "$route.path": function (newVal) {
      // 先清空數(shù)組，確保數(shù)組中只存放一個路由信息
      if (this.openeds.length > 0) {
        this.openeds = [];
      }
      // newVal為路由 /pay/PayIndex 
      let str = newVal.split("/");
      // url為/pay  打開/pay所對應(yīng)的菜單項(xiàng)
      let url = "/" + str[1];
      this.openeds.push(url);
    },
  },
};
</script>

可通過default-openeds指定想要打開的菜單項(xiàng)(也可設(shè)置默認(rèn)打開的菜單項(xiàng) 如?:default-openeds="[/system/user]")?

?通過監(jiān)聽路由的變化，打開與要跳轉(zhuǎn)的組件頁面相對應(yīng)的菜單項(xiàng)，把變化的路由存放到openeds數(shù)組中，實(shí)現(xiàn)路由跳轉(zhuǎn)動態(tài)的打開與之對應(yīng)的菜單項(xiàng)

以上就是實(shí)現(xiàn)路由跳轉(zhuǎn)打開對應(yīng)模塊菜單項(xiàng)的所有步驟啦文章來源地址http://www.zghlxwxcb.cn/news/detail-619581.html
