final class Var[A] extends Binding[A]
Source variable of data binding expression.
You can manually change the value:
val bindingVar = Var("initial value") bindingVar.value = "changed value"
Then, any data binding expressions that depend on this Var will be changed automatically.

@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. The above rule is not applied to DOM nodes created by XHTML literal. Abind
expression under a DOM node does not affect siblings and parents of that node.- Definition Classes
