el-select结合v-if动态控制template显示隐藏
背景： 根据（取值方式）select框中当选择项：
1：范围匹配的时候，（取值）显示两个输入框（上线，下线）；
2：精确匹配的时候，（取值）显示一个输入框（精确）
代码实现
<el-table-column label="取值方式" min-width="100" align="center"> <template scope="scope"> <el-select v-model="scope.row.extractMode" clearable placeholder="请选择"> <el-option v-for="item in extractModeList" :key="item.value" :label="item.label" :value="item.value"></el-option> </el-select> </template> </el-table-column> <el-table-column label="取值" min-width="300" align="center"> <template scope="scope"> <!-- v-if="!showExactMactchInput0" --> <div v-if="scope.row.extractMode== 'range' || scope.row.extractMode== 'fuzzy'"><!-- --> <el-input size="small" class="limitTable" type="number" v-model="scope.row.lowerLimit" placeholder="请输入下限内容"></el-input> - <el-input size="small" class="limitTable" type="number" v-model="scope.row.upperLimit" placeholder="请输入上线内容"></el-input> </div> <div v-else-if="scope.row.extractMode== 'exacts' || scope.row.extractMode== 'exclude' " > <!-- v-bind:id="'exactlist-' + scope.$index" ref="'exactlist-' + scope.$index" --> <el-input size="small" class="exactTable2" v-model="scope.row.exactMatch" placeholder="请输入精确内容"></el-input> </div> </template> </el-table-column> <el-table-column label="操作" align="center"> <template slot-scope="scope"> <el-button circle type="success" icon="el-icon-circle-plus" @click="handleLabelRowClone(scope.$index, scope.row)"></el-button> <el-button type="danger" icon="el-icon-remove" circle @click="handleLabelRowDelete(scope.$index, scope.row)"></el-button> </template> </el-table-column>
贴图
ps: 由于更入手vue，很多语法没仔细看文档，导致入坑不少；很多很简单的语法会耽搁时间；切记切记。
(坑：1：原本想用scope.$index[下标]作为标识从而v-if判断；经过实验变量无法进行赋值（弃之）
2：用v-bind:id【scope.$index】 进行dom控制style.display;考虑到vue本身仅关注视图层；方式不优好。（弃之）
3：恍惚间，每一行都独立不就是【scope.$index】【scope.row】是同样的；这样也不用监听v-select的change event。(用之)
v-if/else template任务状态{1,2,3};当完成==3时，跳转ftp：//
<el-table-column label="任务状态" prop="taskStatus">
<template slot-scope="scope">
<span v-if="scope.row.taskStatus=='3'" class="c-click" @click="hrefFtpUrl(scope.row)"> {{statusObj[scope.row.taskStatus] + scope.row.exportUrl}}</span>
<span v-else >{{statusObj[scope.row.taskStatus]}}</span>
</template>
</el-table-column>Vue动态控制表格列的显示隐藏
效果
如上图所示，点击table右上方的表格按钮，弹出菜单栏，进行勾选，从而达到表格对应列显示和隐藏
代码
1.HTML部分
<template> <div id="app"> <el-table :data="tableData" border ref="table"> <el-table-column fixed prop="date" label="日期" width="150" v-if="showColumn.date" > </el-table-column> <el-table-column prop="name" label="姓名" width="120" v-if="showColumn.name" > </el-table-column> <el-table-column prop="province" label="省份" width="120" v-if="showColumn.provinces" > </el-table-column> <el-table-column prop="city" label="市区" width="120" v-if="showColumn.city" > </el-table-column> <el-table-column prop="address" label="地址" width="300" v-if="showColumn.adreess" > </el-table-column> <el-table-column prop="zip" label="邮编" width="120" v-if="showColumn.zipCode" > </el-table-column> <el-table-column fixed="right" width="100" align="center"> <template slot="header"> <i class="el-icon-setting" @click="showColumnOption" ></i> </template> <template slot-scope="scope"> <el-button @click="handleClick(scope.row)" type="text" size="small" >查看</el-button > <el-button type="text" size="small">编辑</el-button> </template> </el-table-column> </el-table> <!-- 配置列面板 --> <transition name="fade"> <div class="columnOption" v-show="isShowColumn"> <div class="content"> <div class="head">选择显示字段</div> <div class="body"> <el-checkbox v-model="checkList.date" disabled>日期</el-checkbox> <el-checkbox v-model="checkList.name">姓名</el-checkbox> <el-checkbox v-model="checkList.provinces">省份</el-checkbox> <el-checkbox v-model="checkList.city">市区</el-checkbox> <el-checkbox v-model="checkList.adreess">地址</el-checkbox> <el-checkbox v-model="checkList.zipCode">邮编</el-checkbox> </div> <div class="footer"> <el-button size="small" type="primary" plain @click="saveColumn" >保存列配置</el-button > </div> </div> </div> </transition> </div> </template>
通过 v-if="showColumn.date" 来判断表格对应列的状态
