- 修改标签名称
html

<el-form ref="nodeRef" :model="form" :rules="rules" label-width="80px">
<el-form-item label="点位名称" prop="nodeName">
<el-input v-model="form.nodeName" placeholder="请输入点位名称" />
</el-form-item>
<el-form-item label="所在区域" prop="regionId">
<el-select v-model="form.regionId" placeholder="请选择区域">
<el-option v-for="item in regionOptions" :key="item.id" :label="item.regionName" :value="item.id" />
</el-select>
</el-form-item>
<el-form-item label="商圈类型" prop="businessType">
<el-select v-model="form.businessType" placeholder="请选择商圈类型">
<el-option v-for="dict in business_type" :key="dict.value" :label="dict.label"
:value="parseInt(dict.value)"></el-option>
</el-select>
</el-form-item>
<el-form-item label="合作商" prop="partnerId">
<el-select v-model="form.partnerId" placeholder="请选择合作商" filterable>
<el-option
v-for="item in partnerOptions"
:key="item.id"
:label="item.partnerName"
:value="item.id"
/>
</el-select>
</el-form-item>
<el-form-item label="详细地址" prop="address">
<el-input v-model="form.address" placeholder="请输入详细地址" />
</el-form-item>
<el-form-item label="备注" prop="remark">
<el-input v-model="form.remark" type="textarea" placeholder="请输入内容" />
</el-form-item>
</el-form>
<template #footer>
<div class="dialog-footer">
<el-button type="primary" @click="submitForm">确 定</el-button>
<el-button @click="cancel">取 消</el-button>
</div>
</template>
</el-dialog>- 将新增表单中所在区域改为下拉框
javascript
import { listRegion } from "@/api/manage/region";
const regionOptions = ref([]);
/** 获取区域列表 */
function getRegionList() {
listRegion({
pageNum: 1,
pageSize: 10000
}).then(response => {
regionOptions.value = response.rows
});
}
// 在组件挂载时获取区域列表
onMounted(() => {
getRegionList();
});
html
<el-form-item label="所在区域" prop="regionId">
<el-select v-model="form.regionId" placeholder="请选择区域">
<el-option v-for="item in regionOptions" :key="item.id" :label="item.regionName" :value="item.id" />
</el-select>
</el-form-item>- 将新增表单中归属合作商改为下拉框
javascript
import{listPartner}from"@/api/manage/partner";
const partnerOptions = ref([]);
/** 获取合作商列表 */
function getPartnerList() {
listPartner({
pageNum: 1,
pageSize: 10000
}).then(response => {
partnerOptions.value = response.rows;
});
}
// 在组件挂载时获取合作商列表
onMounted(() => {
getPartnerList();
});
html
<el-form-item label="合作商" prop="partnerId">
<el-select v-model="form.partnerId" placeholder="请选择合作商" filterable>
<el-option
v-for="item in partnerOptions"
:key="item.id"
:label="item.partnerName"
:value="item.id"
/>
</el-select>
</el-form-item>- 将搜索栏修改为区域搜索，并使用下拉框展示
标签改为下拉框
html
<el-form-item label="区域搜索" prop="regionId">
<el-select v-model="queryParams.regionId" placeholder="请选择区域" clearable @change="handleQuery">
<el-option v-for="item in regionOptions" :key="item.id" :label="item.regionName" :value="item.id" />
</el-select>
</el-form-item>调用API、JS
javascript
import { listRegion } from "@/api/manage/region";
const regionOptions = ref([]);
/** 获取区域列表 */
function getRegionList() {
listRegion({
pageNum: 1,
pageSize: 10000
}).then(response => {
regionOptions.value = response.rows
});
}
// 在组件挂载时获取区域列表
onMounted(() => {
getRegionList();
});3 、总结思路
通过本篇，我们学会将修改表单、输入框改为下拉框的通用思路
思路：
- 所涉及的文件：通常是api中所在模块的js文件和view中所在模块vue文件(包含了页面显示的组件和JS函数)
我们以合作商的下拉框为例：
-
调用前端API
想要将输入框变为下拉框并展示数据，我们就要考虑如何从后端获取数据；
在合作商的JS文件中，我们看到有一个可以查询合作商列表的函数，该函数使用get向后端 /manage/partner/list发起请求；
后端 /manage/partner/list 收到请求后会查询合作商列表，并发起响应
-
创建调用函数
设置partnerOPptions用来接收整个后端传来的数据；
listPartner是刚刚API函数，想像它已经获得了后端传来的数据，接着拿到10000条数据(本质是想获得所有数据)，并将其中rows数据交给刚刚创建的partnerOptions，用来稍后使用；
javascript
/** 获取合作商列表 */
function getPartnerList() {
listPartner({
pageNum: 1,
pageSize: 10000
}).then(response => {
partnerOptions.value = response.rows;
});
}
// 在组件挂载时获取合作商列表
onMounted(() => {
getPartnerList();
});- 修改表单
为了展示partnerOptions中的合作商名称数据，使用下拉框；value代表获取数据中的id字段值，key代表获取数据中的id字段作为标识，label代表最终展示的值为数据中的合作商名称；
html
<el-form-item label="合作商" prop="partnerId">
<el-select v-model="form.partnerId" placeholder="请选择合作商" filterable>
<el-option
v-for="item in partnerOptions"
:key="item.id"
:label="item.partnerName"
:value="item.id"
/>
</el-select>
</el-form-item>
