## 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.

### 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>
|
|
<!--
|
|
<setup>
|
|
|
|
import { defineComponent, ref } from 'vue';
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
return {
|
|
value: ref(false),
|
|
};
|
|
},
|
|
});
|
|
|
|
</setup>
|
|

:::warning
|
|
We'll detect some deprecated usages, if your pagination don't appeared or worked as expected, please check rules below:
|
|
- You have to define one of `total` and `page-count`, otherwise we can't determine count of total pages.When both defined, `page-count` taken as priority.
|
|
- If `current-page` is defined, you have to listen `current-page` change, by also define `@update:current-page`, otherwise pagination didn't work.
|
|
- If `page-size` is defined while page size selector displayed(`sizes` included in `layout`), you have to listen `page-size` change as well, by define `@update:page-size`, otherwise change of page size didn't work.

### Events
|
|
| Event Name | Description | Parameters |
|
|
|---------|--------|---------|
|
|
| size-change | triggers when `page-size` changes | the new page size |

|
|
|
:::warning
|
|
Events above are not recommended(but are still supported for compatible reason), better chioce is to use the two-way data binding by `v-model`.
