Pagination

用于在分页内容之间导航的页面导航组件。

Showing 1-10 of 100
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export function PaginationBasicDemo() {
  const [page, setPage] = useState(1);

  return (
    <Pagination page={page} setPage={setPage} perPage={10} totalCount={100} />
  );
}

安装

批量导入

import { Pagination } from "@cloudflare/kumo";

细粒度导入

import { Pagination } from "@cloudflare/kumo/components/pagination";

用法

import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export default function Example() {
  const [page, setPage] = useState(1);

  return (
    <Pagination page={page} setPage={setPage} perPage={10} totalCount={100} />
  );
}

示例

完整控件 (默认)

默认的分页包含首页、上一页、页码输入框、下一页和末页按钮。

Showing 1-10 of 100
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export function PaginationFullDemo() {
  const [page, setPage] = useState(1);

  return (
    <Pagination
      page={page}
      setPage={setPage}
      perPage={10}
      totalCount={100}
      controls="full"
    />
  );
}

简化控件

使用 controls="simple" 获得只包含上一页和下一页按钮的精简分页。

Showing 1-10 of 100
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export function PaginationSimpleDemo() {
  const [page, setPage] = useState(1);

  return (
    <Pagination
      page={page}
      setPage={setPage}
      perPage={10}
      totalCount={100}
      controls="simple"
    />
  );
}

总数未知

当数据源不返回总条数时，请使用 hasNextPage。这在基于游标的 API 中很常见—— 计算总数可能代价高昂甚至不可用。根据响应中的下一页信号来设置它， 以便仅在还存在下一组结果时才启用「下一页」。

没有总数时，用户只能顺序翻页，因此 Pagination 会隐藏首页、末页和页码选择控件。 page 的值对 UI 仍有用，但存储并发送每次请求的游标或续传令牌是你的应用的责任。

const [page, setPage] = useState(1);
const { data } = useQuery({
  queryKey: ["events", page],
  queryFn: () => getEvents({ cursor: cursors[page - 1] }),
});

return (
  <Pagination
    page={page}
    setPage={setPage}
    hasNextPage={data.hasMore}
    text={() => `Page ${page}`}
  />
);
Page 1
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

/** Pagination for an API that reports whether another page exists, but not a total. */
export function PaginationUnknownTotalDemo() {
  const [page, setPage] = useState(1);
  const hasNextPage = page < 3;

  return (
    <Pagination
      text={() => `Page ${page}`}
      page={page}
      setPage={setPage}
      hasNextPage={hasNextPage}
    />
  );
}

中间页状态

位于数据集中间的分页，所有导航均可用。

Showing 41-50 of 100
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export function PaginationMidPageDemo() {
  const [page, setPage] = useState(5);

  return (
    <Pagination page={page} setPage={setPage} perPage={10} totalCount={100} />
  );
}

大数据集

分页可处理页数很多的大数据集。

Showing 1-25 of 1250
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export function PaginationLargeDatasetDemo() {
  const [page, setPage] = useState(1);

  return (
    <Pagination page={page} setPage={setPage} perPage={25} totalCount={1250} />
  );
}

自定义文本

你可以自定义分页的显示文本。

Page 1 - showing 25 per page
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

export function PaginationCustomTextDemo() {
  const [page, setPage] = useState(1);
  return (
    <Pagination
      text={({ perPage }: { perPage?: number }) =>
        `Page ${page} - showing ${perPage} per page`
      }
      page={page}
      setPage={setPage}
      perPage={25}
      totalCount={100}
    />
  );
}

复合组件

如果想更精细地控制布局和功能，请使用复合组件 API。它允许你以任意顺序组合 Pagination.Info、Pagination.PageSize、Pagination.Controls 和 Pagination.Separator。

每页条数选择器

添加一个下拉菜单，让用户选择每页显示的条目数。

Showing 1-25 of 500
Per page:
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

/** Pagination with a page size selector using compound components. */
export function PaginationPageSizeSelectorDemo() {
  const [page, setPage] = useState(1);
  const [perPage, setPerPage] = useState(25);

  return (
    <Pagination
      page={page}
      setPage={setPage}
      perPage={perPage}
      totalCount={500}
    >
      <Pagination.Info />
      <Pagination.Separator />
      <Pagination.PageSize
        value={perPage}
        onChange={(size) => {
          setPerPage(size);
          setPage(1);
        }}
      />
      <Pagination.Controls />
    </Pagination>
  );
}

自定义每页条数选项

通过 options 属性自定义可选的每页条数，默认为 [25, 50, 100, 250]。

Showing 1-10 of 200
Per page:
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

/** Pagination with custom page size options using compound components. */
export function PaginationCustomPageSizeOptionsDemo() {
  const [page, setPage] = useState(1);
  const [perPage, setPerPage] = useState(10);

  return (
    <Pagination
      page={page}
      setPage={setPage}
      perPage={perPage}
      totalCount={200}
    >
      <Pagination.Info />
      <Pagination.Separator />
      <Pagination.PageSize
        value={perPage}
        onChange={(size) => {
          setPerPage(size);
          setPage(1);
        }}
        options={[10, 20, 50]}
      />
      <Pagination.Controls />
    </Pagination>
  );
}

自定义信息文本

使用渲染函数自定义信息文本。

Page 1 of 4
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

/** Pagination with custom info text using compound components. */
export function PaginationCompoundCustomInfoDemo() {
  const [page, setPage] = useState(1);

  return (
    <Pagination page={page} setPage={setPage} perPage={25} totalCount={100}>
      <Pagination.Info>
        {({ page, totalCount }) =>
          `Page ${page} of ${Math.ceil((totalCount ?? 1) / 25)}`
        }
      </Pagination.Info>
      <Pagination.Controls />
    </Pagination>
  );
}

自定义布局

以任意顺序排列组件。这里每页条数选择器位于右侧。

Showing 1-25 of 500
Per page:
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

/** Pagination with page size selector on the right side. */
export function PaginationPageSizeRightDemo() {
  const [page, setPage] = useState(1);
  const [perPage, setPerPage] = useState(25);

  return (
    <Pagination
      page={page}
      setPage={setPage}
      perPage={perPage}
      totalCount={500}
    >
      <Pagination.Info />
      <div className="flex items-center gap-2">
        <Pagination.Controls />
        <Pagination.Separator />
        <Pagination.PageSize
          value={perPage}
          onChange={(size) => {
            setPerPage(size);
            setPage(1);
          }}
        />
      </div>
    </Pagination>
  );
}

下拉式页码选择器

在 Pagination.Controls 上使用 pageSelector="dropdown",可将页码导航的文本输入框 替换为下拉选择器。当希望用户从可用页码列表中选择,而不是手动输入数字时,这很实用。

Showing 1-25 of 500
Per page:
<Pagination page={page} setPage={setPage} perPage={perPage} totalCount={500}>

<Pagination.Info />
<Pagination.Separator />
<Pagination.PageSize
  value={perPage}
  onChange={(size) => {
    setPerPage(size);
    setPage(1);
  }}
/>
<Pagination.Controls pageSelector="dropdown" />
</Pagination>

国际化

使用 labels 属性可针对不同语言环境自定义所有界面文案，所有标签默认为英文。

Affichage de 1-10 sur 100
import { useState } from "react";
import { Pagination } from "@cloudflare/kumo";

/** Pagination with French labels for internationalization. */
export function PaginationI18nDemo() {
  const [page, setPage] = useState(1);

  return (
    <Pagination
      page={page}
      setPage={setPage}
      perPage={10}
      totalCount={100}
      labels={{
        firstPage: "Première page",
        previousPage: "Page précédente",
        nextPage: "Page suivante",
        lastPage: "Dernière page",
        pageNumber: "Numéro de page",
        pageSize: "Taille de page",
      }}
    >
      <Pagination.Info>
        {({ pageShowingRange, totalCount }) => (
          <>
            Affichage de{" "}
            <span className="tabular-nums">{pageShowingRange}</span> sur{" "}
            <span className="tabular-nums">{totalCount}</span>
          </>
        )}
      </Pagination.Info>
      <Pagination.Controls />
    </Pagination>
  );
}

perPagenumber-Number of items displayed per page.
totalCountnumber-Total number of items across all pages.
