method depend on this Binding.Returns the current value of this Binding and mark the current
@dom
method depend on this Binding.Each time the value changes, in the current
@dom
method, all code after the currentbind
expression will be re-evaluated if the current@dom
method is #watching. However, code in current@dom
method and before the currentbind
expression will not be re-evaluated. This rule is not applied to DOM nodes created by XHTML literal. A change related to a DOM node does not affect siblings and parents of the node.- Note
This method must be invoked inside a
@dom
method body.
