/**
|
|
* Single checkbox field. Can be used as a direct replacement for traditional checkbox fields.
|
|
* Checkboxes may be given an optional {@link #labelText} which will be displayed immediately after checkbox.
|
|
*
|
|
* Example usage:
|
|
* new Common.UI.CheckBox({
|
|
* el : $('#id'),
|
|
* labelText : 'someText',
|
|
* value : true
|
|
* });
|
|
*
|
|
* # Values
|
|
*
|
|
* The main value of a checkbox is a boolean, indicating whether or not the checkbox is checked.
|
|
* To check the checkbox use setValue(...) function with parameters:
|
|
*
|
|
* - `true`
|
|
* - `'true'`
|
|
* - `'1'`
|
|
* - `1`
|
|
* - 'checked'
|
|
*
|
|
* Checkbox can be in indeterminate state. Use setValue('indeterminate').
|
|
*
|
|
* Any other value will uncheck the checkbox.
|
|
*
|
|
* To get the checkbox state use getValue() function. It can return 'checked' / 'unchecked' / 'indeterminate'.
|
|
*
|
|
* @property {Boolean} disabled
|
|
* True if this checkbox is disabled.
|
|
*
|
|
* disabled: false,
|
|
*
