To re-apply bindings after clearing a node in knockout.js, you can follow these steps:

  1. First, you need to remove the bindings from the node that you want to clear. You can do this by using the ko.cleanNode() method, which will remove all bindings from the specified node.
  2. Next, you can clear the content of the node by setting its innerHTML to an empty string or removing all its child nodes.
  3. After clearing the node, you can reapply the bindings by calling ko.applyBindings() with the view model and the node that you want to bind to.


Here is an example code snippet showing how to reapply bindings after clearing a node:

1

// Remove bindings from the node
ko.cleanNode(document.getElementById('myNode'));

// Clear the content of the node
document.getElementById('myNode').innerHTML = '';

// Reapply the bindings
ko.applyBindings(viewModel, document.getElementById('myNode'));


By following these steps, you can effectively reapply bindings to a node after clearing it in knockout.js.
