<el-form-item label="综合利用">
<el-checkbox-group v-model="form.functemp">
<el-checkbox :label="32">防洪</el-checkbox>
<el-checkbox :label="16">灌溉</el-checkbox>
<el-checkbox :label="8">调峰调频</el-checkbox>
<el-checkbox :label="4">供水</el-checkbox>
<el-checkbox :label="2">无</el-checkbox>
<el-checkbox :label="1">其他</el-checkbox>
</el-checkbox-group>
</el-form-item>
其中form对象本身没有functemp这个属性
解决方法：
this.form = { ...this.form, functemp: [] }
