最近做一个vue前后端分离的项目,前端框架用element ui,在 使用 el-table 的过程中,需要实现行内编辑,效果大概是这样:
分为下面几个步骤:
(1) 自定义 el-table 的表头(即添加 “新增” 按钮):
<el-table :data="proptabledata.col.filter(data => handleadd || data.name.tolowercase().includes(handleadd.tolowercase()))" highlight-current-row border> </el-table>
<template slot="header" slot-scope="scope"> <el-button v-model="handleadd" size="mini" type="success" round plain @click="handleadd(scope.$index, scope.row)">{{ $t('common.add') }}</el-button> </template>
表头自定义了一个“添加”按钮,点击 el-table 动态添加一行。
(2) el-table 动态添加一行:
let row = { code: '', maxvalue: '', minvalue: '', name: '', valuetype: 'string', id: '', typeid: '', warning: false, isset: true } this.proptabledata.col.push(row)
vue 数据变化驱动 dom 进行更新,给 table 绑定的数据 proptabledata.col 添加一个元素,则表格会添加一行。
proptabledata.sel 保存当前行数据:
this.proptabledata.sel = row
(3) el-table 动态删除一行:
子组件中触发父组件的 delete 事件:
this.$emit('delete', row.id)
(4)当前行状态判断,即是否处于编辑状态,控制表格每一行的按钮元素的移除与插入:
<template slot-scope="scope"> <el-button size="mini" type="primary" round plain v-if="!scope.row.isset" @click="valchange(scope.row,scope.$index,true)">{{ $t('common.edit') }}</el-button> <el-button size="mini" type="primary" round plain v-else @click="valchange(scope.row,scope.$index,true)">{{ $t('common.save') }}</el-button> <el-button size="mini" type="danger" round plain v-if="!scope.row.isset" @click="handledelete(scope.$index, scope.row)">{{ $t('common.delete') }}</el-button> <el-button size="mini" type="danger" round plain v-else @click="valchange(scope.row,scope.$index,false)">{{ $t('common.cancel') }}</el-button> </template>
上面代码中,通过 v-if=“scope.row.isset” 来判断当前行是否处于编辑状态。
如果当前行处于编辑状态,则按钮为“保存”和“取消”,此时可对当前行进行保存和取消操作,且不能新增,除非先保存当前行;
如果当前行处于非编辑状态,则按钮为“编辑”和“删除”状态,此时可对当前行进行编辑和删除操作。
这样,就可以实现 el-table 行内编辑的需求。
完整版代码如下:
