【问题描述】：
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 组件将适用于此目的。
我将不胜感激有关如何实施有效的 QPagination 或其他简单解决方案的建议。

一些代码来演示我想要实现的目标
<template>
<q-page class="fit row wrap justify-center items-start content-start" style="overflow: hidden;">
<div class="q-pa-md" style="width: 450px;">
<q-list bordered separator v-for="(post, index) in posts" :key="index">
<q-item clickable v-ripple>
<q-item-section>
<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>
<div class="q-pa-lg flex flex-center">
<q-pagination
v-model="page"
:min="currentPage"
:max="totalPages"
:input="true"
input-class="text-orange-10"
>
</q-pagination>
</div>
</div>
</q-page>
</template>
<script>
export default {
data() {
return {
posts : [{
id: 1,
title: "title one",
content: "This is content one"
},{
id:2,
title: "title two",
content: "This is content two"
},{
id:3,
title: "title three",
content: "This is content three"
}],
page: 1,
currentPage:0,
nextPage: null,
totalPages:5,
}
}
}
</script>

如果您提供您尝试过的代码，我们可以帮助修复它。但我们不能只提供一个完整的解决方案。加入他们的不和谐，他们真的很有帮助，我相信那里有人可以提供帮助

谢谢 hurnhu。坦率地说，我已经多次尝试实现 QPagination 组件，但是查看模板、脚本和组件的 api，我仍然无法理解这个组件是如何工作的。如果文档中有更多关于此的信息会很有帮助。
