The binding application process takes place primarily in the bindingAttributeSyntax module, which defines the ko.bindingContext class as well as the ko.applyBindings method. The high-level overview looks like this:
The
ko.applyBindingsmethod is called with the viewmodel.A binding context is constructed using the viewmodel.
The binding provider is retrieved from
ko.bindingProvider.instance.Knockout works with the DOM tree:
It is passed through the binding provider's node preprocessor (except the root node)
The binding handlers for the node are constructed using the binding provider
The binding handlers are sorted by ensuring that any bindings in their
afterproperty are loaded firstThe binding handlers are iterated through, calling each handler's
initandupdatefunction.
The first three steps are pretty straightforward; even the walking algorithm is just a simple recursion that applies bindings to a node and then iterates over its children to preprocess and bind them. The real...
