vue+element实现分页--之--前端分页

效果图:

访问的数据量小,一次返回所有数据,再次利用elementUI-Table 和el-pagination组件进行展示,关键点事数据的筛选

 官网的完整案例
 <div class="block">
    <span class="demonstration">完整功能</span>
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage4"
      :page-sizes="[100, 200, 300, 400]" //显示 5条/页的值
      :page-size="100"
      layout="total, sizes, prev, pager, next, jumper" //分别对应了[共33条, 5条/页,<.......>]
      :total="400"> //设置总条数
    </el-pagination>
  </div>

<script>
  export default {
    methods: {
      handleSizeChange(val) {
        console.log(`每页 ${val} 条`);
      },
      handleCurrentChange(val) {
        console.log(`当前页: ${val}`);
      }
    },
    data() {
      return {
        currentPage1: 5,
        currentPage2: 5,
        currentPage3: 5,
        currentPage4: 4
      };
    }
  }
</script>　　

　demo的使用

 <el-table
                :data="list"
                style="width: 100%"
                @selection-change="selectItem">
            <el-table-column type="selection" width="50"></el-table-column>
            <el-table-column label="用户名"  prop="userName" width="150"></el-table-column>
            <el-table-column label="用户代码" prop="userCode" width="150"></el-table-column>
            <el-table-column label="所属机构代码" prop="comCode" width="140"></el-table-column>
            <el-table-column label="用户描述" prop="userDescription" width="300"></el-table-column>
            <el-table-column label="用户状态" align="center" prop="userState" width="100">
                <template scope="scope">
                    <div>
                        <!--                        {{ scope.row.userState | userState }}-->
                        {{scope.row.userState == 0 ? "启用" : scope.row.userState == 1 ? "禁用" : "解锁"}}
                    </div>
                </template>
            </el-table-column>
            <el-table-column label="创建时间" prop="makeDate" width="140"></el-table-column>
            <el-table-column label="操作" width="200" align="center">
                <template scope="scope">
                    <div>
            <span>
              <router-link :to="{ name: 'usersEdit', params: { id: scope.row.userCode }}"
                           class="btn-link edit-btn"> 编辑 </router-link>
            </span>
                        <span>
              <el-button size="small" type="danger" @click="confirmDelete(scope.row)">删除</el-button>
            </span>
                    </div>
                </template>
            </el-table-column>
        </el-table>
        <div class="pos-rel p-t-20">
            <btnGroup :selectedData="multipleSelection" :type="'users'"></btnGroup>
            <div class="block pages">

                <el-pagination
                        @current-change="handleCurrentChange"
                        @size-change="handleSizeChange"
                        layout="total, sizes,prev, pager, next"
                        :page-sizes="[1, 5,8, 10]"
                        :page-size="limit"
                        :current-page="page"
                        :total="total">
                </el-pagination>
            </div>
        </div>

接着设置data(){   }

    data() {
      return {
          list:[],
        tableData: [],
        realname: '',
        multipleSelection: [],
        pagesize: 8,
          page:1,  //对应el-pagination current-page
          limit:5,   //和:page-size 对应
          total:null, //和:total对应
      }
    },

　请求数据

      getAllUsers() {
        this.loading = true
        const data = {
          params: {
            realname: this.realname,
            page: this.currentPage,
            rows: this.limit
          }
        }//不要了这个是按后台分页所需要的数据
        this.apiGet('admincrud/users', data).then((res) => {
          console.log('res = ', _g.j2s(res))
          this.handelResponse(res, (data) => {
            this.tableData = data.list
            this.dataCount = data.total
              this.pageList()
          })
        })
      },

　数据过滤

        //处理数据
        getList() {
            //es6过滤得到满足搜索条件的展示数据list
            // let list2 = this.data.filter((item, index) =>
            //     item.name.includes(this.tableData)
            // )
            let list=this.tableData;
            this.list = list.filter((item, index) =>
                index < this.page * this.limit && index >= this.limit * (this.page - 1)
            )
            this.total = list.length
        },

　俩个按钮事件的处理函数

        // 当每页数量改变
        handleSizeChange(val) {
            console.log(`每页 ${val} 条`);
            this.limit = val
            this.getList()
        },
        // 当当前页改变
        handleCurrentChange(val) {
            console.log(`当前页: ${val}`);
            this.page = val
            this.getList()
        },

vue+element实现前端分页及前端搜索功能

主要他的这个搜索过滤挺好的简单不要重新访问后台,我自己没时间改了,现在把思路过程放这里
