checkbox |
Displays a single checkbox, enabling the user to check or uncheck it.
The checkbox item always has one of two values the checked value or unchecked
value.
Page Designer item attributes:
-
Settings, Use
Defaults - If set to On, the checkbox uses
the application-level component settings defined in Shared Components, Component
Settings, checkbox.
See Also: Configuring Checkbox
If Use Defaults is set to Off,
the following custom settings appear:
-
Checked Value - Enter the value stored in the page
item if the end user checks the checkbox. The value can be up to 255
characters long.
On a Faceted Search page, if the facet filters a query column based on a
List Of Values, this value must match both LOV display and
return value. If display and return values differ, then you cannot use this
facet type for this column - use the Checkbox Group facet
instead.
-
Unchecked Value - Enter the value stored in the page
item if the user unchecks the checkbox. This attribute can also be left
blank if you want to store NULL when checked. The value can be up to 255
characters long.
Note: This value is used if the page item is populated with a value
which does not match either the Checked Value or Unchecked Value.
|
|
Checkbox Group |
Displays multiple values as checkboxes, enabling the end user to select multiple
values. A list of values is required for items displayed as checkboxes. The values
corresponding to the checked boxes are stored in a single colon-delimited
string.
Note: For Yes/No checkboxes (that is, a checkbox with only one value), Oracle
recommends using a checkbox or a Switch item type.
The following example displays employee names (ename), but returns employee numbers (empno):
SELECT ename, empno FROM emp;

Geocoded Address |
Provides Geocoding functionality that turns a postal address to a coordinate.
Geocoding is performed by the browser using a REST request to the
Oracle Elocation Geocoding Service (https://elocation.oracle.com/elocation/home.html). In order for geocoding
to work, the user's browser must be connected to the internet.
Geocoding input data comes from other page items which are mapped to
parts of an address such as Street, House Number, Postal Code, or City. The Geocoder
displays a popup window with a list of possible matches. After choosing a match, the
item's session state value will be the address coordinate in GeoJSON format.
The Structured Address attribute determines
whether the address parts are provided to the geocoding service in a
structured or unstructured manner. Structured means that
explicit page items are mapped to address parts such as Street, Postal Code, City or
Region. A structured address has more accurate geocoding results, and also allows
for address correction to be sent back to the page item. Unstructured means
that only one item is used for the whole address and the address parts are separated
by comma. Unstructured mode does not support address corrections.
A Geocoded Address item needs at least one other input item to work and for an exact
address requires a maximum of eight input items.
If Structured Address is Off, the item maps to
only one text field or text area where end users enter address parts, separated by
comma. Following item attributes display under Settings the
Property Editor in in Page Designer:
-
Country Type - Select whether to use a static country for
geocoding, or whether to derive the country from an item. Options include:
Static or Item.
-
Country - Select the country to use for
geocoding.
-
Structured Address - Select
Off. Determines whether address parts are provided to
the geocoding service in a structured or unstructured manner.
-
Address Item - Select the item containing
unstructured address parts, separated by a comma.
-
Match Vector Item - Select a page item for
the Geocoder to return the Match Vector. The match vector is a 17-digit string
with detailed information about how each address attribute has been matched
against the data used for geocoding. See item Help for more details.
-
Trigger Geocoding - Determines when to
trigger geocoding. This includes the browser performing the REST request to the
geocoding service and showing the popup window with possible matches. Options
include: Automatic, Dynamic
Action, and jQuery Selector. See item Help
for more details.
If Structured Address is On, the following item
attributes display under Settings the Property Editor in in
Page Designer:
-
Country Type - Select whether to use a
static country for geocoding, or whether to derive the country from an item.
Options include: Static or
Item.
-
Country - Select the country to use for
geocoding.
-
Structured Address - Select
On. Determines whether address parts are provided to
the geocoding service in a structured or unstructured manner.
-
Sanitize Address - Enable this switch to
feed address data from the geocoding service back to the mapped items.
-
Street Item - Select the item containing
the Street part of the address.
-
House Number Item - Select the item
containing the House Number part of the address.
-
Postal Code Item - Select the item
containing the Postal Code part of the address.
-
City Item - Select the item containing
the City part of the address.
-
City Sub Area Item Item - Select the item
containing the City Sub Area part of the address.
-
Match Vector Item - Select a page item
for the Geocoder to return the Match Vector into. The match vector is a
17-digit string with detailed information about how each address attribute has
been matched against the data used for geocoding. See item Help for more
information.
-
Trigger Geocoding - Determines when to
trigger geocoding. This includes the browser performing the REST request to
the geocoding service and showing the popup window with possible matches.
Options include: Automatic, Dynamic
Action, and jQuery Selector. See item
Help for more information.
Note: The Geocoded Address and Display Map items both work with
the Oracle Elocation Map Cloud service (https://maps.oracle.com/elocation/ajax/index.jsp). This service is
accessed by the browser, not by the APEX database on the server. Be aware this may result in data protection consequences
for users. The geocoding items as and display map items store a coordinate in
GeoJSON format (https://de.wikipedia.org/wiki/GeoJSON) Note
that only the "geometry" portion is used. Currently only "Point" geometries are
supported, for example:
{
"type": "Point",
"coordinates": [
13.74081,
51.05363
]
}
|

automatically checks if the entered value is a number. No extra validations are
required. Validation is done on both client and server.
Page Designer attributes:
-
Appearance, Format Mask -
Specifies how the number is to be formatted for display. The locale determines
the decimal separator used for data entry.
-
Settings, Minimum Value - Enter the

Messages. Specify the message display location by updating the application-level
setting, Default Error Display Location.

Specify whether pressing the Enter key while in this field automatically submits
the page.
-
Settings, Does not save state -
Specify whether the password is saved in session state.

browser cache and Application Express session tables. If you do set this
attribute to No, consider setting Store value encrypted in session state
to Yes.

|
Popup LOV |
Displays a text item with a popup list of values icon. When the end user clicks the icon, a popup window appears with a search field, and a list of supported values.
Popup LOV is best suited for large lists since end users can enter search criteria to reduce the available values displayed. For relatively small lists Select List is often better suited. SELECT ename name, empno id

-
Settings, Search - Select how the
search against the entered value is performed. When using Lazy Loading this
setting can have an impact on query performance. Selecting Contains &
Case Sensitive or Contains & Ignore Case prevents the use of
column indexes.
-
Settings, Lazy Loading - Specify
whether matching values are retrieved from the database using Lazy Loading
techniques. Lazy loading retrieves matching records from the database each time

loading a large number of records may impact the time to initially load the
page.
