elementUI 前端实现分页 和 模糊搜索

最近有一些业务需求就是从第三方系统中调取一些数据,那些数据没有分页的参数,所以就需要前端自己去分页

还有一些搜索后端没有处理前端可以自行处理在数据量较小的时候

以下代码主要实现的是搜索和分页的功能基于elementUI

<template>
    <div class="content">
        <el-row>
            <el-input @keyup.enter.native="search" v-model="searchContent" size="small" placeholder="enter或按钮搜索"></el-input>
            <el-button type="primary" size="small" @click="search">搜索</el-button>
        </el-row>

        <el-row>
            <el-input v-model="watchSearch" placeholder="watch监听搜索" size="small"></el-input>
        </el-row>
      
       
         <el-table
            :data="paginationData"
            border
            style="width: 100%;">
            <el-table-column
                prop="id"
                label="id"
                align="center">
            </el-table-column>
            <el-table-column
                prop="listOne"
                label="listOne"
                align="center">
            </el-table-column>
            <el-table-column
                prop="listTwo"
                label="listTwo"
                align="center">
            </el-table-column>
            <el-table-column
                prop="listThree"
                label="listThree"
                align="center">
            </el-table-column>
            <el-table-column
                prop="listFour"
                label="listFour"
                align="center">
            </el-table-column>
            <el-table-column
                prop="listFive"
                label="listFive"
                align="center">
            </el-table-column>
            <el-table-column
                prop="listSix"
                label="listSix"
                align="center">
            </el-table-column>
        </el-table>

    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[5, 10, 15, 20]"
      :page-size="pagesize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="total"
      style="margin:10px 0">
    </el-pagination>

    </div>
</template>

</script>

<style lang="less" scoped>
.content{
   padding: 24px 24px;
   .el-input{
       width: 400px;
       margin: 20px;
   }
}
</style>

具体的效果图:

后面如果不忙的话还会把这个分页和搜索功能封装成组件,偷懒必备
