Controls

Handlers

In UX1, there are predefined navigation controls based on the aps/Button module. They are the same as explained in the general Navigation Controls section. The callback handlers of the navigation buttons can be defined either in the aps.app context, or in the view that inherits the aps/View module. The latter avoids conflicts between handlers defined in different views and assigned the same name, e.g. aps.app.onCancel. Define them along with the init and other single-page flow methods:

onCancel:   function() { ... },
onPrev:     function() { ... },
onNext:     function() { ... },
onSubmit:   function() { ... }

ButtonState Method

In the UX1 environment, you can process the cancel and submit navigation controls using the View/buttonState(control,properties) method, which enables you to change the following properties (defined in the aps/Button module) dynamically:

• label
• visible
• disabled

For example, to change all three properties for the submit control, call this method from a view (this object) as follows:

this.buttonState(
   "submit", {
      label: "Store Configuration",
      visible: false,
      disabled: true
   }
)
