## Pagination 分页
|
||
|
||
当数据量过多时,使用分页分解数据。
|
||
|
||
### 基础用法
|
||
|
||
:::demo 设置`layout`,表示需要显示的内容,用逗号分隔,布局元素会依次显示。`prev`表示上一页,`next`为上一页,`pager`表示页码列表,除此以外还提供了`jumper`和`total`,`size`和特殊的布局符号`->`,`->`后的元素会靠右显示,`jumper`表示跳页元素,`total`表示显示页码总数,`size`用于设置每页显示的页码数量。
|
||
```html
|
||
<div class="block">
|
||
<span class="demonstration">页数较少时的效果</span>
|
||
<el-pagination
|
||
layout="prev, pager, next"
|
||
:total="50">
|
||
</el-pagination>
|
||
</div>
|
||
<div class="block">
|
||
<span class="demonstration">大于 7 页时的效果</span>
|
||
<el-pagination
|
||
layout="prev, pager, next"
|
||
:total="1000">
|
||
</el-pagination>
|
||
</div>
|
||
</div>
|
||
```
|
||
:::
|
||
|
||
### 小型分页
|
||
|
||
在空间有限的情况下,可以使用简单的小型分页。
|
||
|
||
:::demo 只需要一个`small`属性,它接受一个`Boolean`,默认为`false`,设为`true`即可启用。
|
||
```html
|
||
<el-pagination
|
||
small
|
||
layout="prev, pager, next"
|
||
:total="50">
|
||
</el-pagination>
|
||
```
|
||
:::
|
||
|
||
### 附加功能
|
||
|
||
根据场景需要,可以添加其他功能模块。
|
||
|
||
:::demo 此例是一个完整的用例,使用了`size-change`和`current-change`事件来处理页码大小和当前页变动时候触发的事件。`page-sizes`接受一个整型数组,数组元素为展示的选择每页显示个数的选项,`[100, 200, 300, 400]`表示四个选项,每页显示 100 个,200 个,300 个或者 400 个。
|
||
|
||
```html
|
||
<template>
|
||
<div class="block">
|
||
<span class="demonstration">显示总数</span>
|
||
<el-pagination
|
||
@size-change="handleSizeChange"
|
||
@current-change="handleCurrentChange"
|
||
:current-page="currentPage1"
|
||
:page-size="100"
|
||
layout="total, prev, pager, next"
|
||
:total="1000">
|
||
</el-pagination>
|
||
</div>
|
||
<div class="block">
|
||
<span class="demonstration">调整每页显示条数</span>
|
||
<el-pagination
|
||
@size-change="handleSizeChange"
|
||
@current-change="handleCurrentChange"
|
||
:current-page="currentPage2"
|
||
:page-sizes="[100, 200, 300, 400]"
|
||
:page-size="100"
|
||
layout="sizes, prev, pager, next"
|
||
:total="1000">
