HTMLView.bind() method

Binds a view's behaviors to its binding source.

On the first call, this iterates through all compiled factories, calling createBehavior() on each to produce a ViewBehavior instance (e.g., an HTMLBindingDirective), and then immediately binds it. This is where event listeners are registered, expression observers are created, and initial DOM values are set.

On subsequent calls with a new source, existing behaviors are re-bound to the new data source, which re-evaluates all binding expressions and updates the DOM accordingly.

Signature:

bind(source: TSource, context?: ExecutionContext<TParent>): void;

Parameters

Parameter	Type	Description
source	TSource	The binding source for the view's binding behaviors.
context	ExecutionContext<TParent>	(Optional) The execution context to run the behaviors within.

Returns:

void
