behavior: decimal

floating number input element behavior.

Elements

that have this behavior applied by default:

• <input type="decimal" /> - inline float input element

Model

Upon initialization the behavior creates following DOM structure:

<input>
  <caption>
  <button.plus>
  <button.minus>
</input>

Where <caption> will have behavior:edit applied with corresponding filter set. <button.plus>/<button.minus> sub-elements will be created if the input has attribute step defined.

All sub-elements will have :synthetic state flag set on them.

Attributes

that this behavior knows about:

• value=float - initial value of the input element
• min=float - minimal allowed value.
• max=float - maximal allowed value.
• step=float - increment/decrement step. If this property is defined the behavior will create additional -/+ buttons.
• novalue="text" - if editbox is empty then it shows text provided by the novalue attribute. You can style this state by using :empty CSS selector.
• readonly -  declares that element is read only.

Events

Aside of standard set of events (mouse, keyboard, focus) behavior: button generates:

• EDIT_VALUE_CHANGED event - value of the element was changed due to user actions. Posted (asynchronous) event.
• EDIT_VALUE_CHANGING event - sent when value of the element is about to change. Synchronous event.

Value

integer or undefined, reflects current status of internal editing buffer.

Special key combinations

• LEFT, CTRL+LEFT, SHIFT+LEFT, CTRL+SHIFT+LEFT
• RIGHT, CTRL+RIGHT, SHIFT+RIGHT, CTRL+SHIFT+RIGHT
• HOME, SHIFT+HOME
• END, SHIFT+END
