Use the autoComplete tag to present a
drop-down list of candidate text values that a user can select from for
an input text box. The text values can be produced by an activity or can
be on a clipboard page. 5.4 PROJ-890
At runtime, the 
icon indicates that the field is supported by an autocomplete tag.
- Unlike a Local List (defined as a Table Type on
the General tab of the Property form), the
list presented at runtime by an autoComplete tag is not static and can
vary from time to time or from user to user.
- Unlike the Dynamic Select control, the list presented at runtime
need not be obtained from a Code-Pega-List structure
(typically produced by querying the PegaRULES database or another
database).
The standard HTML property rule
AutoComplete incorporates an autoComplete JSP
tag, and allows you to set most attributes of the
autoComplete and acDataSource JSP tags as
parameters. Enter an autoComplete JSP tag into hand-crafted HTML code
only in special situations where the standard HTML property rule does not
meet your needs.
Example
This JSP tag begins operation after the user types two input
characters. It presents a drop-down list for a text box that is 50
characters wide, highlighting the characters that match user input
typed in each list element. The data is retrieved by the
acDataSource JSP tag.
<pega:autoComplete
name="AC"
highlight="true"
size="50"
minChars="2">
<pega:acDataSource name="ACDS"
type="ClipboardPage"
sourceName="ACDatasource"
clientCache="false"
searchPropertyName="Employee"
displayField="EmpName"
partialSearch="true"
ignoreCase="true"
maxResults="true"
allFields="true" />
</pega:autoComplete>
Complete
syntax
In the syntax presentations below:
- Square bracket characters
[ and ]
define optional parts of the tag. Do not type the brackets.
- JSP tag delimiters <pega and
/> mark the
start and end of the tag.
- Replace any text in italics with your choice of value of that
type.
<pega:autoComplete
name="name"
[highlight="true|false" ]
[size = "nn" ]
[sendingTimeout = "nn" ]
[delimiter = "zzz"]
[minChars ="nn" ]
[listingWidth = "nn"]
[value = "value"] >
<pega:acDataSource .... />
</pega:autocomplete>
The name attribute is required.
