javascript - 如何从同一个类中的另一个方法检索最后插入的 id？

Question

我在 Home 类中有两个方法，分别为 addProperty 和 uploadImages。

我从 jquery dropzone 调用 uploadImages() 方法来发布图像，并调用 addProperty() 将表单输入插入数据库。

我想将最后插入的 ID 从 addProperty 方法传递到 uploadImages 以将图像详细信息保存到数据库中。

我想将图像详细信息插入到名为 tbl_property_images 的表中

1. 文件上传工作
2. 表单输入也成功插入

问题:

我需要使用propertyid将图像详细信息插入表中，propertyid是我们从$result获得的最后插入的ID addProperty 方法中的变量。

Answer 1

解决方案1创建一个过程，它将插入记录并返回插入记录的 id。

解决方案2创建一个过程，将所有数据插入到相应的表中并返回成功或失败。
