Sending requests to the server and changing contents of an Application Express page dynamically, using AJAX and Javascript, is pretty normal for most APEX developers. In practice, over the years, several different approaches developed for these requirements. And especially in older applications, we often find the htmldb_Get Javascript function being used.
In the latest Application Express Release 5.1, htmldb_Get has been formally desupported (Release Notes); but actually this function was never documented. So it’s time to get rid of htmldb_Get in applications.
In our latest issue, we introduce a simple AJAX requirement and show how this can be implemented either declaratively with Dynamic Actions or programmatically with Javascript code and documented APIs.
