前言
<font color=#999AAA >本文大概内容：
例如：随着ElementUI前後端互動的技術的更新，使用者的的體驗越來越好。本文主要針對使用者在保持原頁面結構，再添加另一個頁面，并可以按需要調整兩個頁面之間的比例大小.</font>
<hr style=" border:solid; width:100px; height:1px;" color=#000000 size=1">
一、ElementUI如何在原有頁面添加另外一個頁面并實作關聯增删查改？
<font color=#999AAA >示例：如下圖，我們在原來頁面增删查改及基礎上，選中某一行，點選該公司後，直接在該頁面展示關聯的所有企業客戶的頁面，并且實作查詢、批量删除、分頁等功能。（注意：彈框也可以實作，但是我們希望可以少去打開及關閉彈框的操作步驟，而且同一頁面顯示更直接、友善）
如：要展示的頁面
二、實作步驟
1.ElementUI代碼
<font color=#999AAA >第1頁面的代碼如下（示例）：
// 前面搜尋框的代碼省略....
<el-table stripe style="width:100%;" ref="table" :data="tableData" :default-sort="defaultSort"
height="600px" row-key="id" highlight-current-row @row-click="companyClick"
@selection-change="handleSelection" @sort-change="handleSort">
<el-table-column prop="id" label="ID" type="selection"></el-table-column>
<el-table-column type="index" width="60px" label="行号"></el-table-column>
<el-table-column prop="name" label="機關名稱" width="300"></el-table-column>
<el-table-column prop="type" label="機關類型" width="100">
<template slot-scope="scope">
<el-tag v-if="scope.row.type === 'A'" size="small" type="warning">A類(收稅)</el-tag>
<el-tag v-else size="small" type="success">B類(免稅)</el-tag>
</template>
</el-table-column>
// 中間省略若幹....
<el-table-column fixed="right" label="操作" width="100">
<template slot-scope="scope">
<el-button size="mini" type="success" icon="icon iconfont icon-jihuopeizhi"
@click="handleInvCo(scope.row)">修改
</el-button>
</template>
</el-table-column>
</el-table>
<el-pagination background highlight-current-row
@size-change="handleSizeChange" @current-change="handleCurChange"
:current-page="curPage" :page-size="pageSize" :page-sizes="pageSizes" :total="total"
layout="prev, pager, next, total, sizes, jumper">
</el-pagination>
<font color=#999AAA >第2頁面的代碼如下（示例）：
<span slot="header">關聯企業</span>
<el-form ref="companySearchForm" :model="filterParams" :inline="true" >
<el-form-item >
<el-input v-model="filterParams.companyName" placeholder="企業名稱" size="mini"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" icon="el-icon-search" @click="getPageCompany" size="mini">查詢</el-button>
</el-form-item>
</el-form>
<el-button type="danger" icon="el-icon-delete" @click="deleteAll" size="mini">删除</el-button>
<el-table ref="table" :data="companyTableData" height="540px" @selection-change="handleSelection">
<el-table-column prop="companyid" label="companyid" type="selection" width="55"></el-table-column>
<el-table-column prop="companyName" label="企業名稱"></el-table-column>
</el-table>
<el-pagination background layout="prev, pager, next" :total="pageTotal" @current-change="currentChange" >
</el-pagination>
2.思路：很簡單
1.1 首先通過el-row、el-col、el-card等将兩個頁面組合在一起。
1.2 其次在首頁el-table 欄内設定 @row-click="companyClick"點選事件，并且設定點選時高亮，highlight-current-row
1.3 第2頁面其實跟第1頁面都差不多，但是要注意像表格資料映射名字要換一個名字ref="table" :data="companyTableData"，及分頁也要換一個名字el-pagination :total="pageTotal" @current-change="currentChange"
1.3 最後兩個頁面的elementui代碼如下：
<el-row :gutter="24">
<el-col :span="16">
<el-card>
<span slot="header">開票機關</span>
<div>
<el-row>
<el-button size="mini" type="primary" icon="el-icon-circle-plus-outline" @click="addInvCo()">添加</el-button>
<el-button type="warning" icon="el-icon-delete" size="mini" @click="handleDeletes()">删除</el-button>
</el-row>
<el-table stripe style="width:100%;" ref="table" :data="tableData" :default-sort="defaultSort"
height="600px" row-key="id" highlight-current-row @row-click="companyClick"
@selection-change="handleSelection" @sort-change="handleSort">
<el-table-column prop="id" label="ID" type="selection"></el-table-column>
<el-table-column type="index" width="60px" label="行号"></el-table-column>
<el-table-column prop="name" label="機關名稱" width="300"></el-table-column>
<el-table-column prop="type" label="機關類型" width="100">
<template slot-scope="scope">
<el-tag v-if="scope.row.type === 'A'" size="small" type="warning">A類(收稅)</el-tag>
<el-tag v-else size="small" type="success">B類(免稅)</el-tag>
</template>
</el-table-column>
<el-table-column prop="license" label="執照編号" width="300"></el-table-column>
<el-table-column prop="legalPerson" label="法人" width="150"></el-table-column>
<el-table-column fixed="right" label="操作" width="100">
<template slot-scope="scope">
<el-button size="mini" type="success" icon="icon iconfont icon-jihuopeizhi"
@click="handleInvCo(scope.row)">修改
</el-button>
</template>
</el-table-column>
</el-table>
<el-row style="text-align: right;margin-top: 10px">
<el-pagination background highlight-current-row
@size-change="handleSizeChange" @current-change="handleCurChange"
:current-page="curPage" :page-size="pageSize" :page-sizes="pageSizes" :total="total"
layout="prev, pager, next, total, sizes, jumper">
</el-pagination>
</el-row>
</div>
</el-card>
</el-col>
<el-col :span="8">
<el-card>
<span slot="header">關聯企業</span>
<div>
<el-form ref="companySearchForm" :model="filterParams" :inline="true" >
<el-form-item >
<el-input v-model="filterParams.companyName" placeholder="企業名稱" size="mini"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" icon="el-icon-search" @click="getPageCompany" size="mini">查詢</el-button>
</el-form-item>
</el-form>
<el-row>
<el-button type="danger" icon="el-icon-delete" @click="deleteAll" size="mini">删除</el-button>
</el-row>
<el-table ref="table" :data="companyTableData" height="540px" @selection-change="handleSelection">
<el-table-column prop="companyid" label="companyid" type="selection" width="55"></el-table-column>
<el-table-column prop="companyName" label="企業名稱"></el-table-column>
</el-table>
<el-row style="text-align: right;margin-top: 10px">
<el-pagination background layout="prev, pager, next" :total="pageTotal" @current-change="currentChange" >
</el-pagination>
</el-row>
</div>
</el-card>
</el-col>
</el-row>
2.js代碼：主要是以下方法調用理清關系
<font color=#999AAA >上述方法代碼如下：
// 點選開票機關擷取相關公司客戶
companyClick: function(row){
var _this = this;
_this.filterParams.current = 1;
_this.filterParams.invoiceCompanyid = row.id;
_this.getPageCompany();
},
// 第2頁面根據不同頁面查詢結果
currentChange: function (current) {
this.filterParams.current = current;
this.getPageCompany();
},
// 第2頁面查詢公司客戶的方法（上述點選查詢方法也是這個）
getPageCompany: function(){
var _this = this;
_this.doGetData(_this.companyBindListUrl,_this.filterParams,function (r) {
if(r.success){
_this.companyTableData = r.data;
_this.pageTotal = r.total;
}
})
},
