To specify settings after the init, use this syntax:

Methods

To call a method use this syntax:

Available methods

Key Description
create Creates the control (default)
destroy Destroys the selectBox control and reverts back to the original form control
disable Disables the control (i.e. disabled=“disabled”)
enable Enables the control
value If passed with a value, sets the control to that value; otherwise returns the current value
options If passed either a string of HTML or a JSON object, replaces the existing options; otherwise Returns the options container element as a jQuery object
control Returns the selectBox control element (an anchor tag) for working with directly
refresh Updates the selectBox control’s options based on the original controls options
instance Returns the SelectBox instance, where you have more methods available (only in v1.2.0-dev
available) as in the SelectBox class below.

API SelectBox

You can instantiate the selectBox also through a classic OOP way:

var selectBox = new SelectBox($('#mySelectBox'), settings = {});
selectBox.showMenu();

The public methods are:

refresh()
destroy()
disable()
enable()

getLabelClass()
getLabelText()
getSelectElement()
getOptions(String type = 'inline'|'dropdown')

hideMenus()
showMenu()

setLabel()
setOptions(Object options)
setValue(String value)

removeHover(HTMLElement li)
addHover(HTMLElement li)

disableSelection(HTMLElement selector)
generateOptions(jQuery self, jQuery options)
handleKeyDown(event)
handleKeyPress(event)
init(options)
keepOptionInView(jQuery li, Boolean center)
refresh()
removeHover(HTMLElement li)
selectOption(HTMLElement li, event)

Events

Events are fired on the original select element. You can bind events like this:

$('select').selectBox().change(function () {
    alert($(this).val());
});

Available events

Key Description
focus Fired when the control gains focus
blur Fired when the control loses focus
change Fired when the value of a control changes
beforeopen Fired before a dropdown menu opens (cancelable)
open Fired after a dropdown menu opens (not cancelable)
beforeclose Fired before a dropdown menu closes (cancelable)
close Fired after a dropdown menu closes (not cancelable)

Known Issues

  • The blur and focus callbacks are not very reliable in IE7. The change callback works fine.
