This plugin allows you to create an autocomplete input field based on Yahoo's User Interface Library.

This plugin originally implemented Arthur Clemens' Foswiki:Extensions/AutoCompleteAddOn as a extension, which allows users to provide an autocomplete text box using the %AUTOCOMPLETE% syntax, and also in DataForms (shown below), but has since grown in its own right.



Before you can use this plugin, you need to set up some data for the autocomplete. Examples can be found at AutoCompletePluginTestData.

In Topics and Templates

This plugin expands the %AUTOCOMPLETE{...}% variable, which takes the parameters described in AutoCompletePlugin#Parameters.

In DataForms

To use this plugin in DataForms, create a form template as descibed in DataForms#Defining_a_form. This plugin adds the autocomplete type of field. To pass the parameters required by the plugin, place them in the Values column. An example is shown below:

Name Type Size Values Tooltip message Attributes
Username autocomplete 25em datatopic="Sandbox.AutoCompletePluginTestData" datasection="usernames" delimchar="," itemformat="item[0] + ' (' + item[1] + ')'"    

You can use many of same attributes as you would in topics, except the following:
  • name
  • size
  • value
  • class
  • formname

For a working example of this, see AutoCompletePluginFormExample.


Parameter Comment Default Example
name A unique name for the textfield required name="users"
datatopic The topic with data. Should be formatted as comma-separated string, or as an array of arrays (see AutoCompletePluginTestData#usernames for an example). Use with datasection. required datatopic="Sandbox.AutoCompletePluginTestData"
datasection The topic section with data. Use with datatopic. required datasection="usernames"
size The width of the input field in em or px. 20em size="20em" or size="200px"
value Default value of the input field none value="AutoCompletePlugin"
tabindex The tabindex of the textfield none tabindex="2"
class Name of css class to add to the input field none class="foswikiInputField"
formname Name of the form which the input field is part of none form="userlist"
itemformat The format of an item string in the autocomplete list. Use if the autocomplete list should display different names than the input field - for instance with full person names. The javascript input argument is item. item itemformat="item[0] + ' (' + item[1] + ')'"
delimchar Used to accept multiple delimeted queries. none delimchar=","
onblur, onfocus, onchange, onselect, onmouseover, onmouseout Javascript parameters for the textfield. none onfocus="foswiki.Form.clearBeforeFocusText(this);"
itemselecthandler Defines a javascript function to be executed when an item is selected. See none itemselecthandler="submitJumpForm"


If installed, the following should create an jump box:

<script type="text/javascript">
var SubmitJump = function(sType, aArgs) {
<form name="myJumpForm" action="%SCRIPTURLPATH{"view"}%/%BASEWEB%/%BASETOPIC%">%AUTOCOMPLETE{name="topic" datatopic="Sandbox.AutoCompletePluginTestData" onfocus="foswiki.Form.clearBeforeFocusText(this);" onblur="foswiki.Form.restoreBeforeFocusText(this);" datasection="topiclist" value="Jump" formname="myJumpForm" class="foswikiInputField foswikiInputFieldBeforeFocus"  itemselecthandler="SubmitJump" size="128px" }%</form>
