In this chapter, we will cover:
- Adding JavaScript code to your application
- Creating a tag cloud with AJAX
- Creating visual effects with JavaScript libraries
- Enhancing your application with the Google API
- Including Google maps
- Embedding multimedia objects in your application
- Creating a region selector
- Sending mail via APEX
- Uploading and downloading files
- Calling APEX from an Oracle form
In the first two chapters, we described the tasks to create a basic APEX web application. In this chapter, we will extend our application with some nice features such as visual effects, a tag cloud, and a Google map.
Many of these features are made possible with the use of JavaScript. JavaScript enables dynamic features such as dynamic list of values, drag and drop functionality, different effects on popping-up and disappearing of items.
Since APEX 4.0, many of these JavaScript features can be built using plug-ins. However, for some features you still need to use JavaScript. By the way, you also need to have good knowledge of JavaScript if you want to make use of the extensive possibilities of Google maps.
