ivew-admin 校验 自定义验证表单多层嵌套

1.prop=对象

 <FormItem label="身高："  :label-width="" prop="shapeDifference.heightSpaceT2">
          <Input v-model="formItem.shapeDifference.heightSpaceT2" placeholder="请保留两位小数"  ></Input>
      </FormItem>

2.校验

'shapeDifference.heightSpaceT2':[
               { validator: validateheightSpaceT2, trigger: 'blur' },
          ],

3.规则：

 const  validateheightSpaceT2 = (rule, value, callback) => {
                console.log()
                console.log(value)
                 var reg=/(^[-]{}[-]*$)|(^[-]*\.[-]{}$)/
                if (!value) {
                    return callback(new Error('不能为空'));
                }else if(!reg.test(value)) {
                    callback(new Error('请输入一个整数或者保留小数点后两位'));
                }else {
                     callback();
                }
      };
