【vue 项目】element-select选择器 以省市下拉框联动为例 通过value获取label的值 将value和label都传给后端

<el-form-item label="所属城市：" prop="city"> <el-select v-model=".city1" placeholder="请选择省份" size="small" style="width:220px;margin-right: 20px;" @change="selectCity"> <el-option v-for="item in province" :key="" :value="" :label="" /> </el-select> <el-select v-model=".city2" placeholder="请选择城市" size="small" style="width:220px;"> <el-option v-for="item in cities" :key="" :value="" :label="" /> </el-select> </el-form-item>
