EmberJs分页，如何返回首页？

// app/routes/page.js

import Route from '@ember/routing/route';

export default class PageRoute extends Route {
  model(params) {
    // 根据参数获取当前页数据
    // 这里可以使用Ajax请求或其他方式获取数据
    const currentPageData = fetchData(params.pageNumber);

    return {
      currentPageData,
      pageNumber: params.pageNumber
    };
  }
}

// app/controllers/page.js

import Controller from '@ember/controller';

export default class PageController extends Controller {
  get totalPages() {
    // 计算总页数
    const totalItems = getTotalItems();
    const itemsPerPage = getItemsPerPage();
    return Math.ceil(totalItems / itemsPerPage);
  }

  actions: {
    goToPage(pageNumber) {
      // 跳转到指定页
      this.transitionToRoute('page', pageNumber);
    },

    goToFirstPage() {
      // 返回首页
      this.transitionToRoute('page', 1);
    }
  }
}

<!-- app/templates/page.hbs -->

{{#each model.currentPageData as |item|}}
  <!-- 显示当前页数据 -->
{{/each}}

{{#if totalPages}}
  <button {{action "goToFirstPage"}}>返回首页</button>
  {{#each (range 1 totalPages) as |pageNumber|}}
    <button {{action "goToPage" pageNumber}}>{{pageNumber}}</button>
  {{/each}}
{{/if}}
