vue的表格和分页

骑猪看日落 2022-11-03 01:33 165阅读 0赞

前面有提到在vue里面，对于表格的使用：vue2.0 + element-ui 实战项目-渲染表格(四)[https://www.jianshu.com/p/fea8cacc04b9][https_www.jianshu.com_p_fea8cacc04b9]，在实战的过程中，往往还要选择一个合适的分页，搭配着一起使用，尤其是数据比较多的时候，必然会做出分页效果。

关于一些经常用到的参考文档：这里都罗列一下,查找起来比较方便

--------------------

1：在组件里面找一个自己比较喜欢的分页的样式[https://element.eleme.cn/\#/zh-CN/component/pagination][https_element.eleme.cn_zh-CN_component_pagination]

其实我们可以看到，文档里面的样式非常的简单  
复制一下这段代码

<el-pagination
      background
      layout="prev, pager, next"
      :total="1000">
    </el-pagination>

就可以在页面上看到一个静态的分页的效果了

2：最重要的一个步骤就是点击分页的办法

// 初始页currentPage、初始每页数据数pagesize和数据data
        handleSizeChange: function (size) {
          this.pagesize = size;
          console.log(this.pagesize); //每页下拉显示数据
        },
        handleCurrentChange: function (currentPage) {
          this.currentPage = currentPage;
          console.log(this.currentPage); //点击第几页
        },

3：对表格中获取到的json数据进行处理

:data="pvData.slice((currentPage - 1) * pagesize, currentPage * pagesize)"

4:将前面的静态分页也进行修改一下，加上方法和变量

<el-pagination
          style="margin: 12px 0px"
          background
          @size-change="handleSizeChange"
          @current-change="handleCurrentChange"
          :current-page="currentPage"
          :page-sizes="[5, 10, 20, 40]"
          :page-size="pagesize"
          layout="total, sizes, prev, pager, next, jumper"
          :total="pvData.length"
        >
        </el-pagination>

5：写一个完整的实例：

json

{"msg":"success","total":0,"code":1,"data":[{"id":6,"userOrganId":null,"userName":"super","sex":1,"realName":"super","birthday":null,"password":"202cb962ac59075b964b07152d234b70","roleId":1,"roleName":"角色1","organId":1,"organName":"部门1","authority":0,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":13,"userOrganId":null,"userName":"super2","sex":1,"realName":"super","birthday":null,"password":"202cb962ac59075b964b07152d234b70","roleId":1,"roleName":"角色1","organId":1,"organName":"部门1","authority":0,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":14,"userOrganId":null,"userName":"999","sex":1,"realName":"999","birthday":null,"password":"d41d8cd98f00b204e9800998ecf8427e","roleId":1,"roleName":"1","organId":1,"organName":"1","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":27,"userOrganId":null,"userName":"21","sex":null,"realName":"21","birthday":null,"password":"d41d8cd98f00b204e9800998ecf8427e","roleId":1,"roleName":"","organId":1,"organName":"","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":28,"userOrganId":null,"userName":"111","sex":1,"realName":"111","birthday":null,"password":"202cb962ac59075b964b07152d234b70","roleId":1,"roleName":"1","organId":1,"organName":"14","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":29,"userOrganId":null,"userName":"212","sex":0,"realName":"121","birthday":null,"password":"d41d8cd98f00b204e9800998ecf8427e","roleId":1,"roleName":"1","organId":1,"organName":"13","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1}]}

实例代码

<template>
      <div class="tab-container">
        <el-table
          :data="pvData.slice((currentPage - 1) * pagesize, currentPage * pagesize)"
          border
          fit
          highlight-current-row
          style="width: 100%"
        >
          <el-table-column
            prop="userName"
            label="用户名"
            width="180"
          ></el-table-column>
    
          <el-table-column prop="realName" label="姓名"></el-table-column>
          <el-table-column prop="sex" label="性别"  :formatter="formatSex"></el-table-column>
          <el-table-column prop="organName" label="所属部门"></el-table-column>
          <el-table-column prop="authority" label="权限"></el-table-column>
          <el-table-column prop="roleName" label="角色"></el-table-column>
          
        </el-table>
    
        <el-pagination
          style="margin: 12px 0px"
          background
          @size-change="handleSizeChange"
          @current-change="handleCurrentChange"
          :current-page="currentPage"
          :page-sizes="[5, 10, 20, 40]"
          :page-size="pagesize"
          layout="total, sizes, prev, pager, next, jumper"
          :total="pvData.length"
        >
        </el-pagination>
      
    
      </div>
    </template>
    <script>
    //调用接口
    import {getQuerycheckList} from "@/api/permission/user";
    
    export default {
      data() {
        return {
          // 分页
          currentPage: 1, //初始页
          pagesize: 5, //    每页的数据
          total: 0,
          pvData: [],
          
        };
      },
    
      created() {
        this.getQuerycheckList();
      },
      methods: {
        // 初始页currentPage、初始每页数据数pagesize和数据data
        handleSizeChange: function (size) {
          this.pagesize = size;
          console.log(this.pagesize); //每页下拉显示数据
        },
        handleCurrentChange: function (currentPage) {
          this.currentPage = currentPage;
          console.log(this.currentPage); //点击第几页
        },
    
        //查询题目列表信息接口
        getQuerycheckList() {
          const params = {
            organId: 1,
            userOrganId: 1,
            authority: 0,
            page: 1,
            rows: 5,
            isPagination: false,
          };
          getQuerycheckList(params).then((res) => {
            console.log("查询题目列表信息", res);
            this.pvData = res.data;
          });
        },
        //格式化性别
        formatSex(row, column) {
        return row.sex === 1? "男" : "女";
        }
      },
    };
    </script>
    <style scoped>
    .tab-container {
      margin: 30px;
    }
    </style>

效果：
