vue+elementUI组件table实现前端分页功能

前端分页和后端分页就是请求的差异，前端分页的话只请求一次，所以要在render table组件的时候控制下数据

:data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)"   //不多解释

再就是设置分页器total等于table数据的长度

:total="tableData.length"

点击分页器的操作

methods: {
    handleSizeChange(val) {
      console.log(`每页 ${val} 条`);
      this.currentPage = 1;
      this.pageSize = val;
    },
    handleCurrentChange(val) {
      console.log(`当前页: ${val}`);
      this.currentPage = val;
    }
  }

千言万语不如上个demo~

<template>
  <div>
    <el-table :data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)" style="width: 100%">
      <el-table-column prop="date" label="日期" width="180">
      </el-table-column>
      <el-table-column prop="name" label="姓名" width="180">
      </el-table-column>
      <el-table-column prop="address" label="地址">
      </el-table-column>
    </el-table>
    <!-- 分页器 -->
    <div class="block" style="margin-top:15px;">
      <el-pagination align='center' @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="currentPage" :page-sizes="[1,5,10,20]" :page-size="pageSize" layout="total, sizes, prev, pager, next, jumper" :total="tableData.length">
      </el-pagination>
    </div>
  </div>

</template>

 <script>
export default {
  data() {
    return {
      tableData: [
        {
          date: "2016-05-02",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1518 弄"
        },
        {
          date: "2016-05-04",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1517 弄"
        },
        {
          date: "2016-05-01",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1519 弄"
        },
        {
          date: "2016-05-03",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1516 弄"
        }
      ],
      currentPage: 1, // 当前页码
      total: 20, // 总条数
      pageSize: 1 // 每页的数据条数
    };
  },
  methods: {
    handleSizeChange(val) {
      console.log(`每页 ${val} 条`);
      this.currentPage = 1;
      this.pageSize = val;
    },
    handleCurrentChange(val) {
      console.log(`当前页: ${val}`);
      this.currentPage = val;
    }
  }
};
</script>
