vue el-table实现行内编辑功能

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:

<template>

<el-dialog class="uiot-dialog"

width="900px"

:visible.sync="isShow"

:before-close="beforeClose"

:close-on-click-modal="false"

:title="$t('basicData.device.propDlg.dlgTitle')"

@open="open">

<el-table :data="propTableData.col.filter(data => handleAdd || data.name.toLowerCase().includes(handleAdd.toLowerCase()))"

highlight-current-row

border>

<el-table-column label="No."

type="index"

align="center"

width="50"></el-table-column>

<el-table-column :label="$t('basicData.device.propDlg.code')">

<template slot-scope="scope">

<span v-if="scope.row.isSet">
