-->
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 =%<nop>AUTOCOMPLETE%= syntax, and also in %SYSTEMWEB%.DataForms (shown below), but has since grown in its own right.

%TOC%

---++ Usage

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

---+++ In Topics and Templates

This plugin expands the =%<nop>AUTOCOMPLETE{...}%= variable, which takes the parameters described in %TOPIC%#Parameters.

---+++ In !DataForms

To use this plugin in %SYSTEMWEB%.DataForms, create a form template as descibed in %SYSTEMWEB%.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 Sandbox.AutoCompletePluginFormExample.

---+++ Parameters

| *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 Sandbox.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="%TOPIC%"= |
| =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 http://developer.yahoo.com/yui/autocomplete/#customevents. | none | =itemselecthandler="submitJumpForm"= |

---+++ Example

If installed, the following should create an jump box:

__Source:__
<verbatim>
<script type="text/javascript">
var SubmitJump = function(sType, aArgs) {
    document.myJumpForm.submit();
}
</script>
<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>
</verbatim>

__Rendered:__
<script type="text/javascript">
var SubmitJump = function(sType, aArgs) {
    document.myJumpForm.submit();
}
</script>
<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>

---++ Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

If you have any problems, or if the extension isn't available in =configure=, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.
