@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.- Definition Classes
