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).

<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.

<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.

<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.

<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.

<template>
  <div class="block">
    <span class="demonstration">Total item count</span>
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      v-model:currentPage="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"
      v-model:currentPage="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"
      v-model:currentPage="currentPage3"

      v-model:currentPage="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>
<!--
<setup>

  import { defineComponent, ref } from 'vue';

  export default defineComponent({
    setup() {
      const handleSizeChange = (val) => {
        console.log(`${val} items per page`);
      };
      const handleCurrentChange = (val) => {
        console.log(`current page: ${val}`);
      };

      return {
        currentPage1: ref(5),
        currentPage2: ref(5),
        currentPage3: ref(5),
        currentPage4: ref(4),
        handleSizeChange,
        handleCurrentChange,
      };
    },
  });

</setup>

:::

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

<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>
-->

popper-class custom class name for the page size Select's dropdown string
prev-text text for the prev button string
next-text text for the next button string
disabled whether Pagination is disabled boolean false
hide-on-single-page whether to hide when there's only one page boolean -

:::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
current-change triggers when current-page changes the new current page
prev-click triggers when the prev button is clicked and current page changes the new current page
next-click triggers when the next button is clicked and current page changes the new current page

:::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. :::

Slots

Name Description
custom content. To use this, you need to declare slot in layout
