您可以使用 eventbus or Vuex. Below is simple example with vuex. Here 正在使用 Vue3 进行演示。

const { Toast } = bootstrap

const Home = {
  template: `
    <div>
      <h5>Home</h5>
      <router-link to="/1">Page 1</router-link>
    </div>
  `
}

const Page = {
  template: `
    <div>
      <h5>Page 1</h5>
      <form>
        <h6>Form</h6>
        <button class="btn btn-primary" @click="handleSubmit">Submit</button>
      </form>
    </div>
  `,
  methods: {
    handleSubmit() {
      this.$store.dispatch('setToast', true)
      this.$router.push('/')
    }
  }
};

const routes = [
  { path: '', component: Home },
  { path: '/1', component: Page }
]

const router = new VueRouter({
  routes
});

const store = new Vuex.Store({
  state: {
    toast: false
  },
  mutations: {
    updateToast(state, payload) {
      state.toast = payload;
    }
  },
  actions: {
    setToast({ commit }, data) {
      commit("updateToast", data);
    },
  },
  getters: {
    getToast(state) {
      return state.toast;
    }
  }
});

new Vue({
  el: "#app",
  router,
  store,
  methods: {
    submitHandler() {
      const toast = new Toast(this.$refs.toast)
      toast.show()
      this.$store.dispatch('setToast', false)
    }
  },
  computed: {
    toastState() {
      return this.$store.getters.getToast
    }
  },
  watch: {
    toastState(newT, oldT) {
      if (newT) this.submitHandler()
    }
  }
})
