进行验证的步骤
1、表单el-form 添加 :model="form" ref="form" :rules="rules"，注意是 :model="form"不是v-model，而后每个el-form-item绑定prop
2、不循环的示例在官网可看
3、循环表单的验证：
3-1、el-form-item 绑定 :prop="`addList[${index}][orderNum]`" :rules="rules.orderNum"
注意不循环的表单每个el-form-item 不需要单独加:rules="rules.orderNum"
然后prop的名字要与data中的rules数组对象的名称相同即可
3-2、js判断时，此处的orderNum也就是data中的rules中的名称
`this.$refs.form.validateField('orderNum', (valid) => {
//valid返回的是规则集中写的错误提示信息，如果满足条件，返回的就是空
if (valid) {
return this.$refs["form"].clearValidate('orderNum');
}
});`
