vue3+Element Plus实现自定义穿梭框的详细代码
作者：左小白
找到一个好用的vue树形穿梭框组件都很难,又不想仅仅因为一个穿梭框在element-ui之外其他重量级插件,本文给大家分享vue3+Element Plus实现自定义穿梭框的示例代码,感兴趣的朋友一起看看吧
先上效果图：具体细节可以自己调整这里主要说明 派单，取消这两个按钮的实现
DOM部分代码：
<el-row style="min-height: 7.5rem">
<el-col :span="10" style="border: 1px solid #E1E1E1;border-radius: 5px">
<div>
<div style="border-radius: 5px 5px 0px 0px;
border-bottom: 1px solid #42A4ED;display: flex;
justify-content: space-around;background: #42A4ED">
<div id="rec" style="
font-weight: bolder;
cursor: pointer;/*鼠标变成手指样式*/
transition: all 0.3s;
color: #fff;">
<p style="padding: 10px 10px;height: 40px;"></p>
</div>
</div>
<div style="padding-bottom: 20px;margin: auto;
min-height: 15%;width:80%;font-size: .2rem;
color:#0c1a24;background-color: #fff;">
<el-row>
<el-col :span="20" style="margin-left: 40px; margin-top: 10px;">
<el-input :style="{ margin: 'auto', height: '30px'}" v-model.trim="formData.orgName"
v-show="flag == 'REC'" placeholder="请输入组织名称">
<template #append>
<img @click="getUserData()" src="@/assets/images/icon/search.png"
style="position:relative;top:0px;right: 0px;cursor: pointer">
</template>
</el-input>
</el-col>
</el-row>
</div>
<el-table v-loading="flagTbale" ref="selectedLeft" align='center' :row-style="{ height: '30px', padding: '0 0' }"
highlight-current-row :data="tableData" @selection-change="handleLeftSelectionChange"
:cell-style="{ padding: '3px', background: '#fff', paddingLeft: '0', color: '#666' }"
:header-cell-style="{ background: '#42A4ED', color: '#FFFFFF', height: '20px', fontSize: '0.2rem', fontWeight: 'bold' }"
:header-row-style="{ padding: '10px' }">
<el-table-column type="selection" width="50" prop="select"></el-table-column>
<el-table-column :show-overflow-tooltip="true" align="center" v-for="col in cols" :key="col.id"
:label="col.label" :prop="col.prop" :width="col.width">
</el-table-column>
</el-table>
<div style="height: 1rem;margin-bottom:0.2rem;display: flex; justify-content: center;">
<el-pagination class="pagination" small layout="prev, pager, next" @size-change="handleSizeChange"
:pager-count="3" @current-change="handleCurrentChange" v-model:current-page="pageNum"
v-model:page-size="pageSize" :total="total" />
</div>
</div>
</el-col>
<!-- 中间按钮 -->
<!--中间按钮开始-->
<el-col :span="2" class="layui-transfer-active" style="margin: 230px 3% 0 5%;">
<div>
<el-button class="setting-btn" style="width: 70%;" @click="buttonRight" type="primary"
:disabled="fxDisabled">
派单
</el-button>
</div>
<div>
<el-button class="setting-btn mt20" style="width: 70%;" @click="buttonLeft" type="primary"
:disabled="qxfxDisabled">取消
</el-button>
</div>
</el-col>
<el-col :span="10" style="border: 1px solid #E1E1E1;border-radius: 5px">
<div>
<div style="border-radius: 5px 5px 0px 0px;
border-bottom: 0px solid #42A4ED;display: flex;
justify-content: space-around;background: #42A4ED">
<div id="reced" style="font-family: SourceHanSansCN-Medium;
font-weight: bolder;
cursor: pointer;/*鼠标变成手指样式*/
transition: all 0.3s;
color: #fff;">
<p style="padding: 1px 0px;height: 4px;"></p>
</div>
</div>
<el-table ref="selectedRight" align='center' max-height="470px" :row-style="{ height: '30px', padding: '0 0' }"
highlight-current-row :data="sharedData" @selection-change="handleRightSelectionChange"
:cell-style="{ padding: '3px', background: '#fff', paddingLeft: '0', color: '#666' }"
:header-cell-style="{ background: '#42A4ED', color: '#FFFFFF', height: '20px', fontSize: '0.2rem', fontWeight: 'bold' }"
:header-row-style="{ padding: '10px' }"
>
<el-table-column type="selection" width="55" prop="select"></el-table-column>
<el-table-column :show-overflow-tooltip="true" align="center" v-for="col in cols" :key="col.id"
:label="col.label" :prop="col.prop" :width="col.width">
</el-table-column>
</el-table>
</div>
</el-col>
</el-row>穿梭框的table表头是动态的html中无需修改，使用这个组件首先需要在scripe中创建如下变量
const tableData = ref([]) //左侧数据
const selectedLeft = ref([])// 左侧选中数据
const sharedData = ref([])//右侧数据
const selectedRight = ref([])// 右侧选中数据
//表格loading
const flagTbale = ref(false) //可以去除所有的flagTbale 变量即可去除loading功能
//两个table表头
const cols = ref([
{ id: 1, prop: 'latnName', label: '本地网' },
{ id: 2, prop: 'orgId', label: '组织编码' },
{ id: 3, prop: 'orgName', label: '组织' },
])然后就是最重要的按钮功能
// 取消按钮
const buttonLeft = async () => {
if (!selectedRight.value || !Array.isArray(selectedRight.value)) {
selectedRight.value = [];
}
// 将右侧选中的数据移动到左侧
tableData.value = tableData.value.concat(selectedRight.value);
// 从右侧数据中移除已经移动的数据
sharedData.value = sharedData.value.filter(item => !selectedRight.value.includes(item));
// 清空右侧选中的数据
selectedRight.value = [];
}
// 分享按钮
const buttonRight = async () => {
if (!selectedLeft.value || !Array.isArray(selectedLeft.value)) {
selectedLeft.value = [];
}
// 将左侧选中的数据移动到右侧
sharedData.value = sharedData.value.concat(selectedLeft.value);
// 从左侧数据中移除已经移动的数据
tableData.value = tableData.value.filter(item => !selectedLeft.value.includes(item));
// 清空左侧选中的数据
selectedLeft.value = [];
}按钮禁用逻辑实现
// 按钮是否禁用
const qxfxDisabled = ref(true)
const fxDisabled = ref(true)
// 左侧表格选中事件
const handleLeftSelectionChange = (selection) => {
if (selection.length !== 0) {
fxDisabled.value = false
}
if (selection.length === 0) {
fxDisabled.value = true
}
};
// 右侧表格选中事件
const handleRightSelectionChange = (selection) => {
selectedRight.value = selection;
if (selection.length !== 0) {
qxfxDisabled.value = false
}
if (selection.length === 0) {
qxfxDisabled.value = true
}
};到这里你就可以使用在这个组件了。这是经过插分的代码原本还拥有表头切换的逻辑如有需要可留言.我后续可以在做整理
