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

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

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

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    lt div data-bind  bindHTML  htmlValue  gt  lt  div gt   OR   lt  -- ko bindHTML  htmlValue -- gt  lt  --  ko -- gt
