一、vue+elementui实现下拉表格多选+搜索1.0

二、vue+elementui实现下拉表格多选+搜索+分页+回显+全选2.0

在1.0的基础上，终于可以实现在下拉框表格分页的前提下不同页码的回显辣，分页是前端来分页的（代码略乱且没有封装还很长，随便看看吧）

在这里插入图片描述

1、在使用之前首先要安装Element-ui

1-1、template

<template><div class="goodsindex"><div class="allBox" v-loading="isloading"><el-selectid="equBox"ref="select"clearablemultiplev-model="group.equIdList"placeholder="请选择设备"@change="handleEquId"@click.native="deptogglePanel($event)"><el-optionv-for="(item, i) in group.pageAllList":key="i":label="item.equNumber":value="item.equId"></el-option></el-select><divv-if="group.showTree"class="treeDiv"id="treeDiv"ref="tableList":style="{ top: group.equBoxTop + 'px' }"><div class="equSElect"><el-inputv-model="group.name"clearablesize="mini"style="margin-right: 15px; width: 50%"placeholder="设备编码/名称"@keyup.enter.native="select"></el-input><el-button type="primary" size="mini" @click="select">搜索</el-button></div><!-- 检索结果 --><el-table:data="group.pageList"bordersize="mini"style="margin: 10px 0"ref="multipleTable"id="multipleTable"row-key="equId"@row-click="handleRegionNodeClick"@select="handleCheckBox"@select-all="handleSelectAll"@selection-change="selectionChangeHandle"><el-table-columntype="selection"header-align="center"align="center"width="50"></el-table-column><el-table-columnprop="equNumber"header-align="center"align="center"label="设备编码"min-width="180"></el-table-column><el-table-columnprop="equName"header-align="center"align="center"label="设备名称"min-width="180"></el-table-column></el-table><!-- 分页 --><el-paginationbackground@size-change="handleSizeChange"@current-change="handleCurrentChange":current-page="group.currentPage":page-size="group.pageSize"layout="total, prev, pager, next":total="group.totalPage"></el-pagination></div></div></div>
</template>

1-2、script

};
</script>
