        submitForm() {

                if (valid) {

                    console.log(this.form1, '数据结构');
                } else {
                    console.log('表单验证失败');
                }
            });
        },
        addAll() {
            this.form1.items.push({
                name: '',
                age: '',
                itemall: [{ drink: '', hobby: '' }]
            });
        }
    }
};
</script>

 得到的数据结构如下图，不会影响，都是单独的表单验证：

 这样就实现啦，文章到此结束，希望对你有所帮助~~
