shadcn/ui 动态 pagination

最近由于在 nextui 和 shadcn/ui 做切换，遇到些问题，由于 shadcn/ui 灵活性高，导致没有 pagination 动态配置功能，所以基于以下链接封装了pagination组件 AwsomePagination。

首先

以上链接的 buildLink 是用的query的自适应，而对于的的需求都是用 params的形式去设计，所以调整为新的函数

typescript
const buildLink = useCallback((newPage: number) => {
  return `${parentPath}/${newPage}`;
}, []);

我的component基本运用于服务端组件，所以不需要任何依赖，parentPath则为分页页面的父路由。

然后

renderPageNumbers也做了一些调整

typescript
const renderPageNumbers = useCallback(() => {
    const items: ReactNode[] = [];
    if (totalPageCount <= maxVisiblePages) {
      for (let i = 1; i <= totalPageCount; i++) {
        items.push(
          <PaginationItem key={i}>
            <PaginationLink href={buildLink(i)} isActive={page === i}>
              {i}
            </PaginationLink>
          </PaginationItem>
        );
      }
    } else {
      items.push(
        <PaginationItem key={1}>
          <PaginationLink href={buildLink(1)} isActive={page === 1}>
            1
          </PaginationLink>
        </PaginationItem>
      );

      if (page > 3) {
        items.push(
          <PaginationItem key="ellipsis-start">
            <PaginationLink href={buildLink(page - 2)}>
              <NavigationDots type="left" />
            </PaginationLink>
          </PaginationItem>
        );
      }

      const start = Math.max(2, page - 1);
      const end = Math.min(totalPageCount - 1, page + 1);

      for (let i = start; i <= end; i++) {
        items.push(
          <PaginationItem key={i}>
            <PaginationLink href={buildLink(i)} isActive={page === i}>
              {i}
            </PaginationLink>
          </PaginationItem>
        );
      }

      if (page < totalPageCount - 2) {
        items.push(
          <PaginationItem key="ellipsis-end">
            <PaginationLink href={buildLink(page + 2)}>
              <NavigationDots type="right" />
            </PaginationLink>
          </PaginationItem>
        );
      }

      items.push(
        <PaginationItem key={totalPageCount}>
          <PaginationLink href={buildLink(totalPageCount)} isActive={page === totalPageCount}>
            {totalPageCount}
          </PaginationLink>
        </PaginationItem>
      );
    }

    return items;
  }, []);

这里原文章用 pagination的 dots组件展示样式，并没有jump功能，这里实现了 hover 变 jump 功能。指定 buildLink 去实现对应跳转

typescript
export function NavigationDots({ type }: { type: "left" | "right" }) {
  const wrapperRef = useRef<HTMLDivElement>(null);
  const isHovered = useHover(wrapperRef);
  const hoverDom = useMemo(() => {
    if (type === "left") {
      return <Icon icon={"tabler:arrow-badge-left-filled"} />;
    }
    return <Icon icon={"tabler:arrow-badge-right-filled"} />;
  }, [type]);
  return (
    <div className="cursor-pointer" ref={wrapperRef}>
      {isHovered ? hoverDom : <Icon icon={"tabler:dots"} />}
    </div>
  );
}

这里用到的是 iconify 和 ahooks 去实现，hover 图标切换，点击 jump 对应页面

也就是这样用：

typescript
<PaginationItem key="ellipsis-end">
   <PaginationLink href={buildLink(page + 2)}>
     <NavigationDots type="right" />
   </PaginationLink>
</PaginationItem>

最后

使用：

typescript
 <AwsomePagination parentPath="/home" pageSize={6} page={1} totalCount={total} />

源码：

typescript
"use client";

import { Icon } from "@iconify/react/dist/iconify.js";
import { useHover } from "ahooks";
import { usePathname, useRouter, useSearchParams } from "next/navigation";
import { type ReactNode, useCallback, useMemo, useRef } from "react";
import {
  Pagination,
  PaginationContent,
  PaginationItem,
  PaginationLink,
  PaginationNext,
  PaginationPrevious
} from "../ui/pagination";

export interface AwsomePaginationProps {
  totalCount: number;
  pageSize: number;
  page: number;
  maxVisiblePages?: number;
  parentPath: string;
}
export function NavigationDots({ type }: { type: "left" | "right" }) {
  const wrapperRef = useRef<HTMLDivElement>(null);
  const isHovered = useHover(wrapperRef);
  const hoverDom = useMemo(() => {
    if (type === "left") {
      return <Icon icon={"tabler:arrow-badge-left-filled"} />;
    }
    return <Icon icon={"tabler:arrow-badge-right-filled"} />;
  }, [type]);
  return (
    <div className="cursor-pointer" ref={wrapperRef}>
      {isHovered ? hoverDom : <Icon icon={"tabler:dots"} />}
    </div>
  );
}
export function AwsomePagination({
  pageSize,
  totalCount,
  page,
  maxVisiblePages = 5,
  parentPath
}: AwsomePaginationProps) {
  const router = useRouter();
  const pathname = usePathname();
  const searchParams = useSearchParams();

  const totalPageCount = Math.ceil(totalCount / pageSize);

  const buildLink = useCallback((newPage: number) => {
    return `${parentPath}/${newPage}`;
  }, []);
  const renderPageNumbers = useCallback(() => {
    const items: ReactNode[] = [];
    if (totalPageCount <= maxVisiblePages) {
      for (let i = 1; i <= totalPageCount; i++) {
        items.push(
          <PaginationItem key={i}>
            <PaginationLink href={buildLink(i)} isActive={page === i}>
              {i}
            </PaginationLink>
          </PaginationItem>
        );
      }
    } else {
      items.push(
        <PaginationItem key={1}>
          <PaginationLink href={buildLink(1)} isActive={page === 1}>
            1
          </PaginationLink>
        </PaginationItem>
      );

      if (page > 3) {
        items.push(
          <PaginationItem key="ellipsis-start">
            <PaginationLink href={buildLink(page - 2)}>
              <NavigationDots type="left" />
            </PaginationLink>
          </PaginationItem>
        );
      }

      const start = Math.max(2, page - 1);
      const end = Math.min(totalPageCount - 1, page + 1);

      for (let i = start; i <= end; i++) {
        items.push(
          <PaginationItem key={i}>
            <PaginationLink href={buildLink(i)} isActive={page === i}>
              {i}
            </PaginationLink>
          </PaginationItem>
        );
      }

      if (page < totalPageCount - 2) {
        items.push(
          <PaginationItem key="ellipsis-end">
            <PaginationLink href={buildLink(page + 2)}>
              <NavigationDots type="right" />
            </PaginationLink>
          </PaginationItem>
        );
      }

      items.push(
        <PaginationItem key={totalPageCount}>
          <PaginationLink href={buildLink(totalPageCount)} isActive={page === totalPageCount}>
            {totalPageCount}
          </PaginationLink>
        </PaginationItem>
      );
    }

    return items;
  }, []);

  return (
