本文主要是介绍(el-Transfer)操作(不使用 ts)：Element-plus 中 Select 组件动态设置 options 值需求的解决过程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Ⅰ、Element-plus 提供的Select选择器组件与想要目标情况的对比：
1、Element-plus 提供Select组件情况：
其一、Element-ui 自提供的Select代码情况为(示例的代码)：
// Element-plus 提供的组件代码:
<template><div class="flex flex-wrap gap-4 items-center"><el-selectv-model="value"placeholder="Select"size="large"style="width: 240px"><el-optionv-for="item in options":key="item.value":label="item.label":value="item.value"/></el-select><el-select v-model="value" placeholder="Select" style="width: 240px"><el-optionv-for="item in options":key="item.value":label="item.label":value="item.value"/></el-select><el-selectv-model="value"placeholder="Select"size="small"style="width: 240px"><el-optionv-for="item in options":key="item.value":label="item.label":value="item.value"/></el-select></div>
</template><script lang="ts" setup>
import { ref } from 'vue'const value = ref('')const options = [{value: 'Option1',label: 'Option1',},{value: 'Option2',label: 'Option2',},{value: 'Option3',label: 'Option3',},{value: 'Option4',label: 'Option4',},{value: 'Option5',label: 'Option5',},
]

其二、页面的显示情况为：
Ⅱ、在项目中使用 Select 组件遇到的问题：
1、在 table 表格中选中配置操作后，属性值(即：Rpl Port)中的 Select 组件的 options 选项动态展示的操作：
其一、需求描述：
在 Select 组件的 options 选项中，需要根据不同的 环ID 值来展示不同的 Rpl Port 属性的选项值;
因此此时需要涉及两个接口的问题，第一个接口来获取本页面所要展示的属性值，另一个接口来获取对应 环ID 值来展示的 Rpl Port 属性的选项值；
Step1、分别获取两个接口所对应的数据值：
A、获取第一个接口数据的代码：
// 因为此时的代码设置了后台返回的数据值，因此看起来比较冗余，但其实就是个获取页面数据的 get 请求;
// 一进入该页面就需要调用接口来拿到数据值，而此时的 (start, limit) 参数，是因为分页组件的原因，后面会提到;
// 而此时的 get_eastandwest_port(start, limit) 方法，是获取第二个接口数据的方法;// 获取页面数据操作
const get_erps_configuration = async (start, limit) => {get_eastandwest_port(start, limit)console.log('TODO: GET /api/erps/cfg')//按道理应该有的获取数据的格式，但是自己手动设置是不能用如下获取数据;// const resp = await axios.get('/api/erps/cfg', {// params: {// start: start,// limit: limit,// },// })const resp = {"total": 15,"data": [ {"ring_id": "1","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "2","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "3","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "4","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "5","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "6","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "7","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "8","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "9","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "10","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"}]}console.log(resp, 1111111)console.log(resp.data, 222222)console.log(resp.data.data, 33333333)// if (resp?.status === 200 && resp?.data?.data) {// tableData.value = resp.data.data// Total.value = resp.data.total// }if (resp?.data) {tableData.value = resp.dataTotal.value = resp.total}
}B、获取第二个接口数据的代码：
// 此时会将第二个接口获得的数据放在页面已经定义的 eastAndWestData 变量中;// 获取东向端口及西向端口的页面数据操作：
const get_eastandwest_port = async (start, limit) => {console.log('TODO: GET /api/erps/ring/mgmt')//按道理应该有的获取数据的格式，但是自己手动设置是不能用如下获取数据;// const resp = await axios.get('/api/erps/ring/mgmt', {// params: {// start: start,// limit: limit,// },// })const resp = {"total": 15,"existing_rings": [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15],"data": [ {"del": false,"enable": false,"ring_id": "1","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "2","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "3","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "4","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "5","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "6","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "7","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "8","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "9","eport": "GigabitEthernet0/1","wport": "GigabitEthernet0/2","vlan": "1","ring_type": "major","sub_to_mjr": "0"},{"del": false,"enable": false,"ring_id": "10","eport": "GigabitEthernet0/4","wport": "GigabitEthernet0/5","vlan": "1","ring_type": "major","sub_to_mjr": "0"}]}console.log(resp, 4444444)console.log(resp.data, 55555555)console.log(resp.data.data, 666666666)// if (resp?.status === 200 && resp?.data?.data) {// eastAndWestData.value = resp.data.data// }if (resp?.data) {eastAndWestData.value = resp.data}console.log(eastAndWestData.value, 7777777777) // eport、wportconsole.log(eastAndWestData.value[0], 888888888) // eport、wportconsole.log(eastAndWestData.value[0].eport, 88889999) // eport、wport
}Step2、在点击配置操作后，动态获取 Rpl Port 属性的 options 值：
A、代码：
// 此时的 (index,row) 参数值是 table 表格中对应行的索引值和属性值;
// 此时的 allRplPortOptions 是在点击配置后，Rpl Port 可能存在的所有情况，以备下面做 Ring Type 属性与 Rpl Port 属性的联动操作;
// 此时的 rplPortOptions 值是 Rpl Port 属性的 options 的值，其会根据不同的 index 索引值来在 eastAndWestData(第二个接口获取的值) 中获取要展示的 options(即：rplPortOptions) 值;
// 此时也涉及联动的问题：在 Ring Type 属性值为 'non_rpl' 时，Rpl Port 属性默认展示为 0; 而在 Ring Type 属性值为其它时，Rpl Port 属性默认展示为从 eastAndWestData 值中拿到的要展示的 options(即：rplPortOptions) 值;// 即：此时就能动态展示 Select 组件的 options 值的需求;// 点击 table 表格中的配置所触发的操作：
const handleEdit = (index,row) => {console.log(index,1122334);console.log(row,5566778);console.log(row.ring_id,7788991);allRplPortOptions.value = [{value: '0',label: '0',},{value: eastAndWestData.value[index].eport,label: eastAndWestData.value[index].eport,},{value: eastAndWestData.value[index].wport,label: eastAndWestData.value[index].wport,}]if(row.ring_type === 'non_rpl') {rplPortOptions.value = [{value: '0',label: '0',},]} else {rplPortOptions.value = [{value: eastAndWestData.value[index].eport,label: eastAndWestData.value[index].eport,},{value: eastAndWestData.value[index].wport,label: eastAndWestData.value[index].wport,}]}erpsCfgDialogForm.value.ring_id = row.ring_id,erpsCfgDialogForm.value.revertive = row.revertiveerpsCfgDialogForm.value.tc_propgt = row.tc_propgterpsCfgDialogForm.value.version = row.versionerpsCfgDialogForm.value.ring_type = row.ring_typeerpsCfgDialogForm.value.rpl_port = row.rpl_porterpsCfgDialogForm.value.holdoff_timer = row.holdoff_timererpsCfgDialogForm.value.guard_timer = row.guard_timererpsCfgDialogForm.value.wtr_timer = row.wtr_timererpsCfgDialogVisible.value = true
}
B、效果展示为：
// 此时点击配置后的，在 Ring Type 属性默认为 Non RPL(即：'non_rpl')时，Rpl Port 属性的默认值为 0;
2、Rpl Port 属性与 Ring Type 属性的 Select 组件之间的联动操作：
其一、需求描述：
想让 Ring Type 属性与 Rpl Port 属性之间存在联动关系：
A、在 Ring Type 属性值切换为 Non RPL 时，使得 Rpl Port 属性值仅显示为0；
B、在 Ring Type 属性值切换为 RPL Owner 或 RPL Neighbour 时，使得 Rpl Port 属性值显示为从 eastAndWestData 值中拿到的要展示的 options 值；
Step1、由上述已知(即：上述的动态展示)：
在 table 中点击每一行的配置后，已经根据 Ring Type 的值，使得 Rpl Port 属性的值显示为 0，还是显示为从 eastAndWestData 值中拿到的要展示的 options 值；
Step2、Ring Type 属性的联动操作：
A、代码为：
// @change="handleChange" 是 Select 组件提供的 change 方法;
// 此时的 allRplPortOptions 值是在 table 中点击每一行的配置后，所获得的所有的 Rpl Port 属性可能存在的值;
// 在切换 Ring Type 属性值时，且就会触发 handleChange 函数，然后根据 Ring Type 的值是 'non_rpl' 就使 Rpl Port 属性值展示为 0； 若 Ring Type 的值不是 'non_rpl' ，那么就使 Rpl Port 属性值展示为从 eastAndWestData 值中拿到的要展示的 options 值(即：也就是 allRplPortOptions.value.slice(1, 3) 存储的值)；//切换 Ring Type 下拉框所触发的函数;
const handleChange = (val) => {console.log(val, 112233)if (val === 'non_rpl') {erpsCfgDialogForm.value.rpl_port = 0rplPortOptions.value = [{value: '0',label: '0',},]} else {erpsCfgDialogForm.value.rpl_port = ''rplPortOptions.value = allRplPortOptions.value.slice(1, 3)}
}B、效果展示为：
// 在 Ring Type 属性值为 'non_rpl' 时，Rpl Port 属性值为 0；
// 在 Ring Type 属性值不是 'non_rpl' 时，Rpl Port 属性值为两个端口值(即：就是从 eastAndWestData 值中拿到的要展示的 options 值(即：也就是 allRplPortOptions.value.slice(1, 3) 存储的值))；
3、Rpl Port 属性的 Select 组件不能为空的校验规则：
其一、需求描述：
在提交整个配置的 form 表单之前，需要所有的校验都通过后，才能调用下发参数的接口;
而对于 Rpl Port 属性值的需求是，不能为空，否则下发有问题,因此需要对 Rpl Port 属性进行防空校验;
Step1、校验规则：
A、代码为：
// 此时的 holdoff_timer 属性、guard_timer 属性、wtr_timer 属性是对其它的校验规则;
// 而 rpl_port 属性是对 Rpl Port 属性值的校验，且此时触发 rpl_port 属性的方式是 change(即：Rpl Port 属性值发生改变后就会触发校验)，在 Rpl Port 属性值为空时就会有提示，且在校验不通过的情况下不能调用接口和下发参数;// erpsCfg 的规则配置：
const erpsCfgRules = ref({holdoff_timer: [{ required: true, message: '此处不能为空', trigger: 'blur' }, // 此时是防空判断;{pattern:/^(([0-9])|([1-9][0-9])|([1-9][0-9][0-9]|[1-9][0-9][0-9][0-9]|10000))$/,message: '请填写0~10000的值',trigger: 'blur',},],guard_timer: [{ required: true, message: '此处不能为空', trigger: 'blur' }, // 此时是防空判断;{pattern: /^([1-9][0-9]|([1-9][0-9][0-9]|1[0-9][0-9][0-9]|2000))$/,message: '请填写10~2000的值',trigger: 'blur',},],wtr_timer: [{ required: true, message: '此处不能为空', trigger: 'blur' }, // 此时是防空判断;{pattern: /^([1-9]|(1[0-2]))$/,message: '请填写1~12的值',trigger: 'blur',},],rpl_port: [{ required: true, message: '此处不能为空', trigger: 'change' }, // 此时是防空判断],
})B、结果为：
// 在 Rpl Port 属性值为空时，校验报错;
Ⅲ、解决在项目中遇到的其它问题：
1、分页组件的使用过程：
其一、代码为：
// 此时页面使用的 el-pagination 组件情况，Total 是从后台获取的，来决定总共有多少页;
// 此时的 @current-change="handleCurrentChange" 函数是切换第几页后触发的函数;
<div class="project_bottom"><el-pagination v-model:current-page="currentPage" v-model:page-size="pageSize" :small="true" layout="prev, pager, next, jumper" :total="Total" @current-change="handleCurrentChange"/>
</div>
// 此时的 get_erps_configuration(pageSize.value * (currentPage.value - 1),pageSize.value) 中的两个参数，分别表示从哪个值开始(即：start 值)，每次获取的值是多少条(即：limit);onMounted(() => {erps_configuration_refresh()
})// 刷新页面：
const erps_configuration_refresh = () => {get_erps_configuration(pageSize.value * (currentPage.value - 1),pageSize.value,)
}// 获取页面数据操作
const get_erps_configuration = async (start, limit) => {get_eastandwest_port(start, limit)console.log('TODO: GET /api/erps/cfg')//按道理应该有的获取数据的格式，但是自己手动设置是不能用如下获取数据;// const resp = await axios.get('/api/erps/cfg', {// params: {// start: start,// limit: limit,// },// })const resp = {"total": 15,"data": [ {"ring_id": "1","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "2","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "3","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "4","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "5","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "6","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "7","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "8","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "9","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"},{"ring_id": "10","revertive": true,"tc_propgt": false,"version": "v2","holdoff_timer": "0","guard_timer": "500","wtr_timer": "5","ring_type": "non_rpl","rpl_port": "0"}]}console.log(resp, 1111111)console.log(resp.data, 222222)console.log(resp.data.data, 33333333)// if (resp?.status === 200 && resp?.data?.data) {// tableData.value = resp.data.data// Total.value = resp.data.total// }if (resp?.data) {tableData.value = resp.dataTotal.value = resp.total}
}
// 此时是调用 handleCurrentChange() 函数，且默认传值为 val，然后再调用想要页的数据值;// 实现页面的分页效果;
const handleCurrentChange = (val) => {get_erps_configuration(pageSize.value * (val - 1), pageSize.value)
}其二、页面展示为：
2、去掉弹窗右上角的X号样式的操作：
其一、代码为：
// 此时是修改 el-dialog 的样式代码;//去掉 dialog 右侧的 X 标记;
::v-deep(.el-dialog) {.el-dialog__header {.el-dialog__headerbtn {font-size: 30px;// display: none;.el-dialog__close {color: red;display: none; }} // .el-dialog__close {// color: red;// display: none; // }}// 修改操作按钮与整个 form 表单的距离；.el-dialog__footer {margin-top: -30px !important;}
}其二、页面展示为：
// 修改样式后，此时的配置弹窗右侧就不再有X号的样式;
Ⅳ、整体代码的面貌：
其一、整体代码为：
<script setup>
