Observable property that will be bound to other observable(s). Type parameters K1 K2 Parameters bindProperty1
The bind chain with the to() and toMany() methods. Observable properties that will be bound to other observable(s). ( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled & isBEnabled & isCEnabled ) Must be enabled for the button to become enabled, use the following code: button.bind( 'isEnabled' ).toMany(, 'isEnabled', To bind a button to multiple commands (also Observables) so that each and every one of them It is also possible to bind to the same property in an array of observables. Using a custom callback allows processing the value before passing it to the target property: button.bind( 'isEnabled' ).to( command, 'value', value => value = 'heading1' ) ( isCommandEnabled, isUIVisible ) => isCommandEnabled & isUIVisible ) The binding can include more than one observable, combining multiple data sources in a custom callback: button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible', Which corresponds to: button.bind( 'isEnabled' ).to( command ) It is possible to bind more than one property at a time to shorten the code: button.bind( 'isEnabled', 'value' ).to( command ) You can also "rename" the property in the binding by specifying the new name in the to() chain: button.bind( 'isEnabled' ).to( command, 'isWorking' ) Note: To release the binding, use unbind. whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.button.isEnabled instantly equals command.isEnabled,.Or even shorter: button.bind( 'isEnabled' ).to( command ) Binds observable properties to other objects implementing theĬovering the topic of property bindings with some additional examples.Ĭonsider two objects: a button and an associated command (both Observable).Ī simple property binding could be as follows: button.bind( 'isEnabled' ).to( command, 'isEnabled' )
