vue+element分页封装

第一种

---

在components文件夹里建一个pagination.vue组件

<template>
  <div>
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page.sync="currentPage"
      :page-sizes="pageSizes"
      :page-size.sync="pageSize"
      :layout="layout"
      :background="background"
      :total="total"
    >
    </el-pagination>
  </div>
</template>
<script>
// import { scrollTo } from '@/utils/scroll-to'
export default {
  name: "Pagination",
  props: {
    layout: {
      type: String,
      default: "total, sizes, prev, pager, next, jumper"
    },
    pageSizes: {
      type: Array,
      default() {
        return [10, 20, 30, 50];
      }
    },
    total: {
      required: true,
      type: Number
    },
    page: {
      type: Number,
      default: 1
    },
    limit: {
      type: Number,
      default: 20
    },
    autoScroll: {
      type: Boolean,
      default: true
    },
    background: {
      type: Boolean,
      default: true
    }
  },
  computed: {
    currentPage: {
      get() {
        return this.page;
      },
      set(val) {
        this.$emit("update:page", val);
      }
    },
    pageSize: {
      get() {
        return this.limit;
      },
      set(val) {
        this.$emit("update:limit", val);
      }
    }
  },
  methods: {
    handleSizeChange(val) {
      this.$emit("pagination", { page: this.currentPage, limit: val });
      // if (this.autoScroll) {
      //     scrollTo(0, 800)
      // }
    },
    handleCurrentChange(val) {
      this.$emit("pagination", { page: val, limit: this.pageSize });
      // if (this.autoScroll) {
      //     scrollTo(0, 800)
      // }
    }
  }
};
</script>

页面使用

<template>
  <div>
    <Pagination
      v-show="total > 0"
      :total="total"
      :page.sync="form.pageNum"
      :limit.sync="form.pageSize"
      @pagination="getData"
    />
  </div>
</template>
<script>
import Pagination from "@/components/pagination.vue";
export default {
  components: {
    Pagination
  },
  data() {
    return {
      form: {
        pageNum: 1,
        pageSize: 10
      },
      total: 200
    };
  },
  methods: {
    getData() {
      console.log(this.form)
      //请求接口
    }
  },
  mounted() {
    this.getData();
  }
};
</script>

 pagination.vue组件

<template>
  <!-- 分页组件的封装 -->
  <div class="pagination">
    <el-pagination
      @size-change="sizeChange"
      @current-change="currentChange"
      :page-sizes="[1, 5, 10, 15, , 20]"
      layout="total, sizes, prev, pager, next, jumper"

      :page-size="pageSize"
      :total="total"
      :small="small"

    </el-pagination>
  </div>
</template>

<script>
export default {
  name: "Pagination",
  data() {
    return { };
  },
  //子组件接收父组件的值
  props: {
    total: {
      //总条目数
      required: false, //是否必须
      default: 0 //默认值
    },
    pageNum: {
      required: false, //是否必须
      default: 1 //默认值（默认第1页）
    },
    pageSize: {
      required: false, //是否必须
      default: 10 //默认值（默认显示10条）
    },
    small: {
      //是否使用小型分页样式
      required: false, //是否必须
      type: Boolean, //类型
      default: false //默认值
    }
  },
  //计算属性  计算属性是基于他们的依赖做缓存
  computed: {},
  //侦听器 响应数据的变化
  watch: {},
  methods: {
    // size变化
    sizeChange(val) {
      //子组件向父组件传值
      this.$emit("sizeChange", val);
    },
    // 当前页变化
    currentChange(val) {
