带有 QPagination 组件和 laravel paginate() 方法的 Quasar QList 分页

Question

我想对使用 QList 组件制作的列表进行分页

使用 laravel paginate() 方法，我在客户端收到以下分页所需的数据：

current_page:
data:[]
first_page_url:
from:
last_page:
last_page_url:
next_page_url:
path:
per_page:
prev_page_url:
to:
total:

我刚开始使用 Quasar 框架，我想要一个简单的 QList 分页解决方案。

显然 QPagination 组件将适合此目的。

我将不胜感激关于如何实施有效的 QPagination 或其他简单解决方案的建议。

只需使用计算属性基于分页获取数据。

    getData(){
        return  this.posts.slice((this.page-1)*this.totalPages,(this.page-1)*this.totalPages+this.totalPages)
    }

 <q-list bordered separator v-for="(post, index) in getData" :key="index">              
              <q-item clickable v-ripple>
                        <q-item-label> {{ post.title }} | {{ index }}</q-item-label>
                        <q-item-label caption> {{ post.content }}</q-item-label>
                   </q-item-section>
              </q-item>

            </q-list>
