Knockout.js bound input value not updated when I use jquery .val('xyz')

问题

I have an input that has a knockout binding to the value.

When I update the value using jquery's .val() method, the changed value is not reflected in the viewModel.

I need to use jQuery to set this value. How can I trigger the update to the viewModel?

回答1:

.val() does not trigger the change event. So, you can just do .val("blah").change() for KO to pick up the changes.
