vue 下拉框单选、多选以及默认值

背景:

单选框和多选框 都是使用了 el-select,但传给后端的值类型不一样,多选框传的值是 list类型: ['value1','value2'] ,单选框传值和其他类型一样;设置默认值也是如此

效果展示:

 

html 代码如下:

 1 <template>
 2     <div>
 3     <el-form ref="form" :model="form" label-width="80px">
 4     <el-row style="height:30px"  type="flex" >
 5             <el-col :span="4">
 6             <el-form-item label="单选框" >
 7             <el-select v-model="form.selectOne" style="width:140px;">
 8             <el-option label="单选1" value="1"></el-option>
 9             <el-option label="单选2" value="2"></el-option>
10             <el-option label="单选3" value="3"></el-option>
11             <el-option label="单选4" value="4"></el-option>
12             </el-select>
13                 </el-form-item></el-col>
14             </el-row>
15 
16             <el-row style="height:30px"  type="flex" >
17 
18              <el-col :span="12">
19              <el-form-item label="多选框" required>
20                     <el-select v-model="form.selectMultiple" style="width:300px;" placeholder="多选框"  multiple>
21                 <el-option label="多选1" value="1"></el-option>
22                 <el-option label="多选2" value="2"></el-option>
23                 <el-option label="多选3" value="3"></el-option>
24                 <el-option label="多选4" value="4"></el-option>

30             </el-col></el-row>
31     </el-form>
32     </div>
33 </template>

 1 export default {
 2   data() {
 3     return {
 4 
 5         form: {
 6             selectOne:'2',//单选默认值
 7             selectMultiple:['1','2','3'],//多选默认值
