## Pagination
If you have too much data to display in one page, use pagination.
### Basic usage
:::demo Set `layout` with different pagination elements you wish to display separated with a comma. Pagination elements are: `prev` (a button navigating to the previous page), `next` (a button navigating to the next page), `pager` (page list), `jumper` (a jump-to input), `total` (total item count), `size` (a select to determine page size) and `->`(every element after this symbol will be pulled to the right).
```html
<div class="block">
<span class="demonstration">When you have few pages</span>
<el-pagination
layout="prev, pager, next"
:total="50">
</el-pagination>
</div>
<div class="block">
<span class="demonstration">When you have more than 7 pages</span>
<el-pagination
layout="prev, pager, next"
:total="1000">
</el-pagination>
</div>
```
:::
### Number of pagers
:::demo By default, Pagination collapses extra pager buttons when it has more than 7 pages. This can be configured with the `pager-count` attribute.
```html
<el-pagination
:page-size="20"
:pager-count="11"
layout="prev, pager, next"
:total="1000">
</el-pagination>
```
:::
### Buttons with background color
:::demo Set the `background` attribute and the buttons will have a background color.
```html
<el-pagination
background
layout="prev, pager, next"
:total="1000">
</el-pagination>
```
:::
### Small Pagination
Use small pagination in the case of limited space.
:::demo Just set the `small` attribute to `true` and the Pagination becomes smaller.
```html
<el-pagination
small
layout="prev, pager, next"
:total="50">
</el-pagination>
```
:::
### More elements
Add more modules based on your scenario.
:::demo This example is a complete use case. It uses `size-change` and `current-change` event to handle page size changes and current page changes. `page-sizes` accepts an array of integers, each of which represents a different page size in the `sizes` select options, e.g. `[100, 200, 300, 400]` indicates that the select will have four options: 100, 200, 300 or 400 items per page.
```html
<template>
<div class="block">
<span class="demonstration">Total item count</span>
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page.sync="currentPage1"
:page-size="100"
layout="total, prev, pager, next"
:total="1000">
</el-pagination>
</div>
<div class="block">
<span class="demonstration">Change page size</span>
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page.sync="currentPage2"
:page-sizes="[100, 200, 300, 400]"
:page-size="100"
layout="sizes, prev, pager, next"
:total="1000">
</el-pagination>
</div>
<div class="block">
<span class="demonstration">Jump to</span>
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page.sync="currentPage3"
:page-size="100"
layout="prev, pager, next, jumper"
:total="1000">
</el-pagination>
</div>
<div class="block">
<span class="demonstration">All combined</span>
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page.sync="currentPage4"
:page-sizes="[100, 200, 300, 400]"
:page-size="100"
layout="total, sizes, prev, pager, next, jumper"
:total="400">
</el-pagination>
</div>
</template>
<script>
export default {
methods: {
handleSizeChange(val) {
console.log(`${val} items per page`);
},
handleCurrentChange(val) {
console.log(`current page: ${val}`);
}
},
data() {
return {
currentPage1: 5,
currentPage2: 5,
currentPage3: 5,
currentPage4: 4
};
}
}
</script>
```
:::
### Hide pagination when there is only one page
When there is only one page, hide the pagination by setting the `hide-on-single-page` attribute.
:::demo
```html
<div>
<el-switch v-model="value">
</el-switch>
<el-pagination
:hide-on-single-page="value"
:total="5"
layout="prev, pager, next">
</el-pagination>
</div>
<script>
export default {
data() {
return {
value: false
}
}
}
</script>
```
