By using shortcuts you can avoid repetitive coding of HTML or PL/SQL functions. You can use a shortcut to define a page control such as a button, HTML text, a PL/SQL procedure, or HTML. Once defined, you can invoke a shortcut using specific syntax unique to the location in which the shortcut is used. Shortcuts can be referenced many times, thus reducing code redundancy.
This section contains the following topics:
When you create a shortcut, you must specify the type of shortcut you want to create. Oracle Application Express supports the following shortcut types:
Use this type of shortcut to reference a shortcut inside of a JavaScript literal string. This shortcut defines a text string. When the shortcut is referenced, it escapes the single quotation marks required for JavaScript.
Use this type of shortcut to reference a translatable message at run time. Note that since this shortcut does not have a shortcut body, the name of the shortcut must match the corresponding message name. At run time, the name of the shortcut expands to the text of the translatable message for the current language.
Before you can incorporate a shortcut in your application, you must define it and add it to the Shortcuts repository. You reference shortcuts using the following syntax:
"MY_SHORTCUT"
Note that the shortcut name must be capitalized and enclosed in quotation marks.
To define a shortcut:
On the Workspace home page, click the Application Builder icon.
Select an application.
When Application Builder appears, click Shared Components.
Under User Interface, select Shortcuts.
Click Create.
Select one of the following creation methods:
From Scratch
As a Copy of an Existing Shortcut
Follow the on-screen instructions.
New shortcuts are added to the Shortcut repository and are available for use within the following locations:
The Region Source attribute of regions defined as HTML Text (with shortcuts). See "Understanding Regions".
Region Header and Footer Text attribute. See "Specifying a Region Header and Footer".
Item Label attributes and Default Value attribute. See "Items".
Region Templates attributes. See "Customizing Templates".
Once you create a shortcut, it appears on the Shortcuts page. You control how the page displays by making a selection from the View list. Available options include:
Icons (the default) displays each shortcut as a large icon. To edit a shortcut, click the appropriate icon.
Details displays each shortcut as a line in a report. To edit a shortcut, click the name.
Once you create a shortcut, you can alter it by editing attributes on the Edit Shortcut page.
To edit an existing shortcut:
On the Workspace home page, click the Application Builder icon.
Select an application.
Click Shared Components.
Under User Interface, select Shortcuts.
Select a shortcut.
The Edit Shortcut page appears.
To learn more about a specific item on a page, click the item label.
When Help is available, the item label changes to red when you pass your cursor over it and the cursor changes to an arrow and question mark. See "About Field-Level Help".
Click Apply Changes.
The Edit Shortcut page is divided into the following sections: Name, Subscription, Source, Configuration, and Comments.
You can access these sections by scrolling down the page, or by clicking a navigation button at the top of the page. When you select a button at the top of the page, the selected section appears and all other sections are temporarily hidden. To view all sections of the page, click Show All.
Application Builder includes a number of reports designed to help you better manage shortcuts.
