类星体QList分页与QPagination组件和laravel分页()方法

Question

我想对使用 QList 组件创建的列表进行分页

使用 laravel paginate(( 方法，我在客户端接收分页所需的以下数据：

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

我开始使用类星体框架，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现工作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>

只需使用计算属性即可获取基于分页的数据。

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>
</q-list>
