aps/ComboBox¶

Auto-completing text box.

The drop down box’s values are populated from a class called a data provider, which returns a list of values based on the characters that the user has typed into the input box. If OPTION tags are used as the data provider via markup, then the OPTION tag’s child text node is used as the widget value when selected. The OPTION tag’s value attribute is ignored. To set the default value when using OPTION tags, specify the selected attribute on 1 of the child OPTION tags.

Overview ¶

Structure¶

aps/ComboBox is a hybrid containing the aps/Select drop-down box and the aps/TextBox input field.

The functionality of this widget completely matches the functionality of the dijit/form/ComboBox widget.

Find the nested rules for this widget in the recommended Widget Hierarchy.

Query Expression¶

The queryExpr property is a pattern that specifies what query is sent to the data store, based on what the user has typed. Changing this expression will modify whether the results are exact match or partial match. For the search engine, the ${0} is the text entered in the input field. To specify a partial match, the * wildcard is added to the pattern with the following expected results:

${0} - “is”, that is exact match
${0}* - “starts with”
*${0} - “ends with”
*${0}* - “contains”, the default pattern

Examples ¶

Query Expression¶

In the following example, try to test different query expressions.

RUN DEMO

require([
  "aps/Memory",
  "aps/ComboBox",
  "aps/FieldSet",
  "aps/Panel",
  "aps/PageContainer",
  "aps/ready!"
], function(Memory, ComboBox, FieldSet, Panel, PageContainer){
  "use strict";
  var stateStore = new Memory({
      data: [
        {name:"Alabama", id:"AL"},
        {name:"Alaska", id:"AK"},
        {name:"American Samoa", id:"AS"},
        {name:"Arizona", id:"AZ"},
        {name:"Arkansas", id:"AR"},

        {name:"Delaware", id:"DE2"}
      ]
  });

    var page = new PageContainer();
    page.placeAt("stateSelectDiv");
    var panel = new Panel();
    var fieldSet = new FieldSet();

    fieldSet.addChild(new ComboBox({
        store: stateStore,
        queryExpr: "${0}*"
    }));
    panel.addChild(fieldSet);
    page.addChild(panel);
    page.startup();
});

Option Template¶

The following example illustrates the use of the optionTemplate and searchAttr properties.

autoSize boolean¶

Only for PCP / CCP v1. If this property value is set to “true”, then a CSS class is assigned to the widget based on the value of the “size” property: size <= 7 - f-small-size (40px) 7 < size <= 33 - f-middle-size (215px) 33 < size - f-big-size (240px) The default value of this property is true. If you want to use your own CSS class for defining the widget’s size, you should set this property value to “false” and specify your class name in the widget’s “class” property. Default value: true

description string¶

Textual description to be displayed as a small greyed text under the control. Default value: “”.

disabled boolean¶

Specifies if the widget will respond to user input.

Default value: false.

gridSize string¶

This specifies the widget width that is relevant only for widgets inside Container, FieldSet, or Tiles. In other cases it will be ignored.

gridSize string contains few options with number values (from 1 to 12) separated by spaces, which specify the grid size of the widget in different layouts:

- md - desktop

- xs - phone

For example, gridSize: “md-4 xs-2”.

All values below 1, e.g. “md-0”, will be replaced with the empty string (“”), values above 12, e.g. “md-14”, will be reduced to 12 (“md-12”).

Default value: undefined.

hint string¶

Help information in a widget. It is shown under the content of the widget. Deprecated in CCP v2. Default value: “”.

invalidMessage string¶

Tooltip text that appears when the content of the text box is invalid. Default value: “The value entered is not valid.”.

isBusy boolean¶

If the widget is busy then this property is true.

Default value: false.

label string¶

Text that is shown as a label if the widget is placed inside a aps/FieldSet.

Default value: “”.

minLength number¶

The minimum number of characters that end user should type to see autocompletion suggestions list. Default value: 3.

Tooltip text that appears when the content of the text box is empty and the field is required. Default value: “This value is required.”.

optionalText string¶

Text for optional widgets of the Input category. Default value: “(Optional)”.

optionTemplate string¶

Only CCP v2. A template string used to create items in the drop-down menu. If you want to show the id property too, set the optionTemplate property to “${name} (${id})”. Property searchAttr should be equal “customName” to use this property. Default value: “${name}”.

placeHolder string¶

Grayed out initial string in a field. For example, it can display instructions. Default value: “”.

queryExpr string¶

Defines how a pattern entered in the input field is matched against the widget store to select store elements from the drop-down list. Changing this expression will modify whether the results are only exact matches, a “starting with” match, and so on. It is applied to each object property. ${0} will be substituted for the user text. * is used for wildcards. ${0}* means “starts with”, *${0}* means “contains”, ${0} means “is”. Default value: “_${0}_”.

required boolean¶

User is required to enter data in the input field. Default value: false.

searchAttr string¶

Only CCP v2. Specifies an attribute in the data store entries to search for a string that a user is typing. To search a string in the ID (specified by the PropertyID in the store) and in the “name” attribute of all store entries, assign the ‘customName’ string to this property. Default value: “name”.

size number¶

Affects the selection of a CSS class that defines the width of the input field of the widget.

size <= 7        f-small-size (40px)
7 < size <= 33   f-middle-size (215px)
size > 33        f-big-size (240px)

Default value: 10 - PCP / CCP v1, undefined - CCP v2.

Public Methods ¶

METHOD	RETURN	DESCRIPTION
cancel ()	object	Sets the isBusy property to false
destroy ()	undefined	Destroy this widget
extraValidator ()	boolean	Here, you can do additional verifications
focus ()	aps/_input function	Focusing on the focusNode of the current object
get ()	any	Get a property of the Stateful instance
getCustomErrorMessage ()	string	Here, you can return a custom error message
getParents ()	array	Discover and return all parents of the widget
labelFunc (item)
placeAt ()	dijit/_widgetbase function	Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions
set ()	object function	Set a property of the Stateful instance
startup ()	undefined	Gets started after the DOM fragment is added to the document

cancel¶

Sets the isBusy property to false.

Return: object

destroy¶

Destroy this widget. Will also destroy any resources (including widgets) registered via this.own(). This method will also destroy internal widgets such as those created from a template.

Return: undefined

extraValidator¶

Here, you can do additional verifications. Overrided method.

Return: boolean

focus¶

Focusing on the focusNode of the current object.

Return: aps/_input function

get¶

Get a property of the Stateful instance. Get a named property of the Stateful object. The property may potentially be retrieved via a getter method in subclasses.

In the base class, this just retrieves the object’s property.

Return: any

getCustomErrorMessage¶

Here, you can return a custom error message. Overrided method. The method must return a value, only if additional verifications fail. To change standard error messages, use respective properties.

Return: string

getParents¶

Discover and return all parents of the widget.

Return: array

labelFunc¶

ARGUMENT	TYPE	DESCRIPTION
`item`	undefined

placeAt¶

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions. A convenience function providing a simple shorthand mechanism to put an existing (or newly created) widget somewhere in the DOM, and allow chaining.

Return: dijit/_widgetbase function

set¶

Set a property of the Stateful instance. Sets named properties of the stateful object and notifies the watchers of the property. A programmatic setter may be defined in subclasses.

Return: object function

startup¶

Gets started after the DOM fragment is added to the document Called after the widget and its children have been created and added to the page, and all related widgets have finished their create() cycle, up through postCreate().

Note that startup() may be called while the widget is still hidden, for example if the widget is inside a hidden dijit/Dialog or an unselected tab of a dijit/layout/TabContainer. For widgets that need to do layout, it’s best to put that layout code inside resize(), and then extend dijit/layout/_LayoutWidget so that resize() is called when the widget is visible.

Return: undefined

Public Events ¶

EVENT	RETURN	DESCRIPTION
onClick ()	undefined	The method is called when a user clicks on the widget

onClick¶

The method is called when a user clicks on the widget.
