el-pagination分页查询封装

需求：因为需要用到表单查询的地方太多了，所以为了避免每个页面都写分页组件，直接封装好调用就完事了，简简单单

1.创建Pigination.vue公用组件

<template>
  <div :class="{'hidden':hidden}" class="pagination-container">
    <el-pagination
      :background="background"
      :current-page.sync="currentPage"
      :page-size.sync="pageSize"
      :layout="layout"
      :page-sizes="pageSizes"
      :total="total"
      v-bind="$attrs"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
    ></el-pagination>
  </div>
</template>

<script>

export default {
  name: 'Pagination',
  props: {
    total: {
      required: true,
      type: Number
    },
    // 当前页数
    page: {
      type: Number,
      default: 1
    },
    // 限制，一页多多少行
    limit: {
      type: Number,
      default: 20
    },
    // 分页
    pageSizes: {
      type: Array,
      default() {
        return [10, 20, 30, 50, 100]
      }
    },
    layout: {
      type: String,
      default: 'total, sizes, prev, pager, next, jumper'
    },
    background: {
      type: Boolean,
      default: true
    },
    autoScroll: {
      type: Boolean,
      default: true
    },
    hidden: {
      type: Boolean,
      default: false
    }
  },
  computed: {
    // 当前页数
    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.$emit('pagination', { page: this.currentPage, size: val });
      // if (this.autoScroll) {
      //   scrollTo(0, 800);
      // }
    },
    handleCurrentChange(val) {
      this.$emit('pagination', { page: val, size: this.pageSize });
      // if (this.autoScroll) {
      //   scrollTo(0, 800);
      // }
    }
  }
}
</script>

<style scoped>
.pagination-container {
  background: #fff;
  padding-top: 10px;
}
.pagination-container.hidden {
  display: none;
}
</style>

2.需要使用分页组件的页面调用

<template>
    <div class="content-box">
        <div class="container">
            <p>主体页面 2 - 2</p>

            <div class="table-container">
                <el-table
                    ref="Table2"
                    :data="list"
                    style="width: 100%;"
                    show-overflow-tooltip="true"
                    @selection-change="handleSelectionChange"
                    border
                >
                    <el-table-column type="selection" align="center"></el-table-column>
                    <el-table-column label="操作" width="120" align="center" fixed="right"> </el-table-column>
                </el-table>
            </div>

            <!-- 分页组件 -->
            <Pagination :total="total" :page.sync="listQuery.pageNum" :limit.sync="listQuery.pageSize" @pagination="getList"></Pagination>
        </div>
    </div>
</template>

<script>
import Pagination from '@/components/common/Pagination';
import { testApi } from '@/api/test';
const defaultListQuery = {
    pageNum: 1,//给后端的数据，可以根据后端需要更改
    pageSize: 10,
    keyword: ''
};
export default {
    data() {
        return {
            listQuery: Object.assign({}, defaultListQuery),//浅拷贝，引用数据类型相互影响
            list: [],
            total: 0,
            listLoading: true,
            selectedList: []
        };
    },
    components: {
      // 注册分页
        Pagination
    },
    created() {
        this.getList();
    },
    methods: {
        getList() {
            // 获取数据列表
            this.listLoading = true;
            testApi(this.listQuery).then(res => {
                this.listLoading = false;
                this.list = res.data.list;
                this.total = res.data.total;
            });
        },
        handleSelectionChange(val) {
            // 批量选择行数
            this.selectedList = val;
        }
    }
};
</script>
