如何使用Vue实现分页功能

npm install vue vuejs-paginate

<template>
  <div>
    <ul>
      <li v-for="item in displayedItems">{{ item }}</li>
    </ul>
    <paginate
      :page-count="pageCount"
      :click-handler="pageChanged"
    ></paginate>
  </div>
</template>

<script>
import Paginate from "vuejs-paginate";

export default {
  components: {
    Paginate,
  },
  data() {
    return {
      allItems: [],
      currentPage: 1,
      pageSize: 10,
    };
  },
  computed: {
    displayedItems() {
      // 经过分页计算后需要展示的数据
      const startIndex = (this.currentPage - 1) * this.pageSize;
      const endIndex = startIndex + this.pageSize;
      return this.allItems.slice(startIndex, endIndex);
    },
    pageCount() {
      // 总页数
      return Math.ceil(this.allItems.length / this.pageSize);
    },
  },
  methods: {
    pageChanged(pageNumber) {
      // 翻页方法
      this.currentPage = pageNumber;
    },
  },
  mounted() {
    // 在此处获取并设置数据源
    this.allItems = [
      "Item 1",
      "Item 2",
      "Item 3",
      "Item 4",
      "Item 5",
      "Item 6",
      "Item 7",
      "Item 8",
      "Item 9",
      "Item 10",
      "Item 11",
      "Item 12",
    ];
  },
};
</script>

.vuejs-paginate {
  display: flex;
  justify-content: center;

  ul {
    display: flex;
    justify-content: center;
    list-style: none;
    padding: 0;
    margin: 0;

    li {
      margin-right: 0.5rem;
      font-size: 1rem;
      font-weight: 700;

      a {
        color: #333;
        text-decoration: none;
        padding: 0.5rem 1rem;
        border-radius: 0.3rem;
        transition: all 0.3s ease;

        &:hover {
          background-color: #333;
          color: #fff;
        }

        &.active {
          background-color: #333;
          color: #fff;
        }
      }
    }
  }
}

<template>
  <div id="app">
    <pagination></pagination>
  </div>
</template>

<script>
import Pagination from "./components/Pagination.vue";

export default {
  components: {
    Pagination,
