behavior:check

Standard checkbox button implementation. Can be applied to any element to toggle :checked state on it.

Elements

that have this behavior applied by default:

<input type="checkbox"> - standard HTML inline checkbox button;
<button type="checkbox"> - Windows like inline checkbox button, use it as <button type=checkbox >caption</button>.

that this behavior knows about:

checked - if provided will initialize value of runtime state of the flag checked.
name="name" - standard attribute name - name of the input element on a form.
value="..." - standard value attribute (used by behavior:form).
as="string | integer | float | numeric | auto" - defines how value propert is reported to script. By default value of element with value="42" will be just as a string "42" but value="42" as="integer" will yield integer 42.
mixed - this element allows to be in mixed (undetermined) state.

Together with the standard set of events (mouse, keyboard, focus) behavior:check generates:

"input"|"change"/BUTTON_STATE_CHANGED event - the button just changed its state to checked. Asynchronous event.
"press"/BUTTON_PRESS event - mouse down or spacebar key down when button is in focus. Synchronous event.

If value is requested from the element directly then value will have true or false values - reflects current status of :checked state flag.

For mixed checkbox the behavior also accepts null value - undetermined state.

If checkbox element is placed inside a <form> then form's value collection will include value of checkbox@value attribute if it is checked.

N/A - behavior:check does not introduce any specific methods.
