前言

本文大概內容:
例如:隨著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,再新增另一個頁面,並可以按需要調整兩個頁面之間的比例大小.


一、ElementUI如何在原有頁面新增另外一個頁面並實現關聯增刪查改?

範例:如下圖,我們在原來頁面增刪查改及基礎上,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,並且實現查詢、批次刪除、分頁等功能。(注意:彈框也可以實現,但是我們希望可以少去開啟及關閉彈框的操作步驟,而且同一頁面顯示更直接、方便)


如:要展示的頁面

二、實現步驟

1.ElementUI程式碼

第1頁面的程式碼如下(範例):

// 前面搜尋方塊的程式碼省略....
<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="行號"></el-table-column>
       <el-table-column  prop="name" label="單位名稱" width="300"></el-table-column>
       <el-table-column  prop="type" label="單位型別" 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>
// 中間省略若干....
       <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>

第2頁面的程式碼如下(範例):


<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">刪除</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等將兩個頁面組合在一起。

1.2 其次在首頁el-table 欄內設定 @row-click="companyClick"點選事件,並且設定點選時高亮,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對映名字要換一個名字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程式碼如下:

 <el-row :gutter="24">
                    <el-col :span="16">
                        <el-card>
                            <span slot="header">開票單位</span>
                            <div>
                                <el-row>
                                    <el-button size="mini"  type="primary" icon="el-icon-circle-plus-outline" @click="addInvCo()">新增</el-button>
                                    <el-button type="warning" icon="el-icon-delete" size="mini" @click="handleDeletes()">刪除</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="行號"></el-table-column>
                                    <el-table-column  prop="name" label="單位名稱" width="300"></el-table-column>
                                    <el-table-column  prop="type" label="單位型別" 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="執照編號" 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">刪除</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程式碼:主要是以下方法呼叫理清關係

上述方法程式碼如下:

	// 點選開票單位獲取相關公司客戶
	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;
                   }
               })
           },
           

3.最後的頁面如下:
