页面导航上的 AJAX 加载程序 - Oracle Apex 4
我对 apex 开发还很陌生，并且很难找到有关 AJAX 实现的文档。我有一些导航到不同页面的按钮。其中一些页面运行非常昂贵的 sql 语句，并且需要一段时间才能加载。我想添加一个ajax加载器只是为了给用户一些系统当前正在加载下一页的反馈。
我怎样才能做这样的事情？ Apex 4 是否包含 AJAX 还是我需要加载 JQuery 等框架？任何帮助或指导将不胜感激。
I am pretty new to apex development and am having trouble finding documentation on AJAX implementation. I have a few buttons that navigate to different pages. Some of these pages run very expensive sql statements and it takes a while to load. I would like to add an ajax loader just to give the user some feedback that the system is currently loading the next page.
How can I do something like this? Does Apex 4 include AJAX or do I need to load a framework such as JQuery? Any help or direction would greatly be appreciated.
