Nested Tracking

This demo shows ability to track arbitrarily nested models. In this case, both name and descriprion properties of models contain values in many languages - stored as a sub objects. These properties are tracked for changes just like direct object property.

Objects in this example are even more complex, containing also arrays of objects.



Relevant code used in examples:

<div data-bind="with: binder.model.Nested">
	<div>
		<input type="text" data-bind="textInput: rawI18N.name.en" class="col-xs-6" />
		<input type="text" data-bind="textInput: rawI18N.name.pl" class="col-xs-6" />
	</div>
	<div>
		<textarea data-bind="textInput: rawI18N.description.en" class="col-xs-6"></textarea>
		<textarea data-bind="textInput: rawI18N.description.pl" class="col-xs-6"></textarea>
	</div>
	<div class="clearfix"></div>
	<hr />
	<div data-bind="html: '<b>' + rawI18N.name.en + '</b>: ' + rawI18N.description.en" class="col-xs-6" ></div>
	<div data-bind="html: '<b>' + rawI18N.name.pl + '</b>: ' + rawI18N.description.pl" class="col-xs-6" ></div>
