Class OutputView

Create msg callbacks for a comm msg.

Create and promise that resolves to a child view of a given model

Make an event delegation handler for the given eventName and selector and attach it to this.el. If selector is empty, the listener will be bound to this.el. If not, a new handler that will recursively traverse up the event target's DOM hierarchy looking for a node that matches the selector. If one is found, the event's delegateTarget property is set to it and the return the result of calling bound listener with the parameters given to the handler.

This does not properly handle selectors for things like focus and blur (see https://github.com/jquery/jquery/blob/7d21f02b9ec9f655583e898350badf89165ed4d5/src/event.js#L442 for some similar exceptional cases).

Handle message sent to the front end.

Used to focus or blur the widget.

Public constructor

Render a view

Returns

the view or a promise to the view.

Send a custom msg associated with this view.

Triggered on model change.

Update view to be consistent with this.model

Update the DOM classes applied to an element, default to this.el.

Update the DOM classes applied to the widget based on a single trait's value.

Given a trait value classes map, this function automatically handles applying the appropriate classes to the widget element and removing classes that are no longer valid.

class_map: dictionary Dictionary of trait values to class lists. Example: { success: ['alert', 'alert-success'], info: ['alert', 'alert-info'], warning: ['alert', 'alert-warning'], danger: ['alert', 'alert-danger'] }; trait_name: string Name of the trait to check the value of. el: optional DOM element handle, defaults to this.el Element that the classes are applied to.
