## 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>
```
