How to force a view refresh without having it trigger automatically from an observable

Question

Note  this is mostly for debugging and understanding KnockoutJS   Is there a way to explicitly request Knockout to refresh the view from  already bound  view model  I am looking for something like    ko refreshView      I understand that this is not an intended use of Knockout  but I still want to know if there is a such method for debugging and learning purposes

I have created a JSFiddle with my bindHTML knockout binding handler here: https://jsfiddle.net/glaivier/9859uq8t/

First, save the binding handler into its own (or a common) file and include after Knockout.

If you use this switch your bindings to this:

<div data-bind="bindHTML: htmlValue"></div>

OR

<!-- ko bindHTML: htmlValue --><!-- /ko -->

In some circumstances it might be useful to simply remove the bindings and then re-apply   ko cleanNode document getElementById element id   ko applyBindings viewModel  document getElementById element id

You can t call something on the entire viewModel  but on an individual observable you can call myObservable valueHasMutated   to notify subscribers that they should re-evaluate   This is generally not necessary in KO  as you mentioned
